BACKGROUND:

Tetraethyl lead was phased out of gasoline in Uganda in 2005. Recent mitigation of an important source of lead exposure suggests examination and re-evaluation of the prevalence of childhood lead poisoning in this country. Ongoing concerns persist about exposure from the Kiteezi landfill in Kampala, the country's capital.

OBJECTIVES:

We determined blood lead distributions among Kampala schoolchildren and identified risk factors for elevated blood lead levels (EBLLs; >or= 10 microg/dL). Analytical approach: Using a stratified, cross-sectional design, we obtained blood samples, questionnaire data, and soil and dust samples from the homes and schools of 163 4- to 8-year-old children representing communities with different risks of exposure.

RESULTS:

The mean blood lead level (BLL) was 7.15 microg/dL; 20.5% of the children were found to have EBLL. Multivariable analysis found participants whose families owned fewer household items, ate canned food, or used the community water supply as their primary water source to have higher BLLs and likelihood of EBLLs. Distance < 0.5 mi from the landfill was the factor most strongly associated with increments in BLL (5.51 microg/dL, p < 0.0001) and likelihood of EBLL (OR = 4.71, p = 0.0093). Dust/soil lead was not significantly predictive of BLL/EBLL.

CONCLUSIONS:

Lead poisoning remains highly prevalent among school-age children in Kampala. Confirmatory studies are needed, but further efforts are indicated to limit lead exposure from the landfill, whether through water contamination or through another mechanism. Although African nations are to be lauded for the removal of lead from gasoline, this study serves as a reminder that other sources of exposure to this potent neurotoxicant merit ongoing attention.

On February 12th, 2008, Christine Quinn, Speaker of the New York City Council, took to the dais at the City Council Chambers to deliver the State of the City Address.  Towards the 17th page of an 18 page address, the Speaker’s remarks turned to public transit and the Mayor’s recently released PlaNYC initiatives.  While transit is generally a hot topic in New York, Mayor Bloomberg had made transportation a centerpiece of his second term and was spending the winter in a campaign to convince the State Legislature to approve a congestion pricing scheme in Manhattan to finance transportation capital projects. 

“It’s only natural to look at our natural highways, our water ways... to move New Yorkers efficiently and sustainably.” Said Speaker Quinn,  “That’s why we are proposing and the Mayor has agreed to begin developing a comprehensive five borough, year-round New York City Ferry System.”   The Speaker explained that the idea for ferry service originated through a series of public hearings she held with her colleagues in the Council:

 “Soon after, we began exploring the concept of a pilot ferry service for the Rockaways…got a commitment from the Mayor to fund it…and that service should be up and running by this summer.


Two years and twelve days later, the rhetoric of the State of the City speech came crashing to an anti-climactic end, as a report in the Daily News announced the cancellation of the Rockaways service.  The ferry would cease operations at the end of March.  

Plans for a five borough Ferry System have not materialized, except for an East River ferry serving developments along the Queens/Brooklyn waterfront, currently with two sailings during the AM and PM peak hours is expected to offer more frequent service next year  The Rockaway route had not met ridership projections and was recovering only 15-30% of its operational costs from revenues collected at the farebox.   The failure of the Rockaway ferry service, combined with the cancellation of another newly opened ferry service between Yonkers and Lower Manhattan in 2009 has dashed the hopes of some who wished to exploit New York’s water resources to improve commuting options via ferries.  This has led to questions about the feasibility of expanding ferry service in New York City more broadly. 

As large sections of the New York City waterfront are reclaimed from decades of industrial land use, idyllic waterfront parks have been developed next to gleaming residential towers.  It seems only natural that ferries will soon serve a role in transporting residents and visitors to these new neighborhoods throughout the City.  However, recent experiences illustrate the many obstacles facing expanded ferry services in New York City 

BACKGROUND:

Elevated concentrations of mercury have been documented in fish in Lake Chapala in central Mexico, an area that is home to a large subsistence fishing community. However, neither the extent of human mercury exposure nor its sources and routes have been elucidated.

METHODS:

Total mercury concentrations were measured in samples of fish from Lake Chapala; in sections of sediment cores from the delta of Rio Lerma, the major tributary to the lake; and in a series of suspended-particle samples collected at sites from the mouth of the Lerma to mid-Lake. A cross-sectional survey of 92 women ranging in age from 18-45 years was conducted in three communities along the Lake to investigate the relationship between fish consumption and hair mercury concentrations among women of child-bearing age.

RESULTS:

Highest concentrations of mercury in fish samples were found in carp (mean 0.87 ppm). Sediment data suggest a pattern of moderate ongoing contamination. Analyses of particles filtered from the water column showed highest concentrations of mercury near the mouth of the Lerma. In the human study, 27.2% of women had >1 ppm hair mercury. On multivariable analysis, carp consumption and consumption of fish purchased or captured from Lake Chapala were both associated with significantly higher mean hair mercury concentrations.

CONCLUSIONS:

Our preliminary data indicate that, despite a moderate level of contamination in recent sediments and suspended particulate matter, carp in Lake Chapala contain mercury concentrations of concern for local fish consumers. Consumption of carp appears to contribute significantly to body burden in this population. Further studies of the consequences of prenatal exposure for child neurodevelopment are being initiated.

The U.S. health care system faces well-known problems: 47 million people without health insurance, rapidly rising costs that consume 16 percent of the country'e economic output, and widely uneven quality of care. Even many people with coverage are experiencing serious problems paying for the rapidly rising costs of health care and insurance.

This book--a joint product of the National Academy of Public Administration and the National Academy of Social Insurance--undertakes a sweeping analysis of the management and administrative issues that arise in expanding health care coverage. The book identifies the core administrative functions that need to be performed in assuring access to health coverage, describes how these functions are performed at present and under proposed alternatives, draws lessons from experience in the U.S. and abroad, and assesses suggested administrative approaches designed to facilitate the improvement and expansion of health care coverage.

Adequate health care is one of today's most crucial domestic policy concerns. Expanding Access to Health Care is designed to bring together in one place some of the best thinking on the subject, not as an exercise in advocacy, but rather to lay out the issues in a balanced way so that policymakers, researchers, and citizens can better understand the complex details of health care reform.

Objective: To use publicly available secondary data to assess the impact of Brazil's Family Health Program on state level infant mortality rates (IMR) during the 1990s.

Design: Longitudinal ecological analysis using panel data from secondary sources. Analyses controlled for state level measures of access to clean water and sanitation, average income, women's literacy and fertility, physicians and nurses per 10 000 population, and hospital beds per 1000 population. Additional analyses controlled for immunisation coverage and tested interactions between Family Health Program and proportionate mortality from diarrhoea and acute respiratory infections.

Setting: 13 years (1990-2002) of data from 27 Brazilian states.

Main results: From 1990 to 2002 IMR declined from 49.7 to 28.9 per 1000 live births. During the same period average Family Health Program coverage increased from 0% to 36%. A 10% increase in Family Health Program coverage was associated with a 4.5% decrease in IMR, controlling for all other health determinants (p<0.01). Access to clean water and hospital beds per 1000 were negatively associated with IMR, while female illiteracy, fertility rates, and mean income were positively associated with IMR. Examination of interactions between Family Health Program coverage and diarrhoea deaths suggests the programme may reduce IMR at least partly through reductions in diarrhoea deaths. Interactions with deaths from acute respiratory infections were ambiguous.

Conclusions: The Family Health Program is associated with reduced IMR, suggesting it is an important, although not unique, contributor to declining infant mortality in Brazil. Existing secondary datasets provide an important tool for evaluation of the effectiveness of health services in Brazil.

Mass transit is a critical infrastructure of urban environments worldwide. The public uses it extensively, with roughly 9 billion mass transit trips occurring annually in the United States alone according to the U.S. Department of Transportation data. Its benefits per traveler include lower emissions of air pollutants and energy usage and high speeds and safety records relative to many other common modes of transportation that contribute to human health and safety. However, mass transit is vulnerable to intrusions that compromise its use and the realization of the important benefits it brings. These intrusions pertain to physical conditions, security, external environmental conditions, and equity. The state of the physical condition of transit facilities overall has been summarized in the low ratings the American Society of Civil Engineers gives to mass transit, and the large dollar estimates to maintain existing conditions as well as to bring on new improvements, which are, however, many times lower than investments estimated for roadways. Security has become a growing issue, and numerous incidents point to the potential for threats to security in the US. External environmental conditions, such as unexpected inundations of water and electric power outages also make transit vulnerable. Equity issues pose constraints on the use of transit by those who cannot access it. Transit has shown a remarkable ability to rebound after crises, most notably after the September 11, 2001 attacks on the World Trade Center, due to a combination of design and operational features of the system. These experiences provide important lessons that must be captured to provide proactive approaches to managing and reducing the consequences of external factors that impinge negatively on transit.

An invisible network of digital technology systems underlies the highly visible networks of roads, waterways, satellites, and power-lines. Increasingly, these systems are becoming the "infrastructure's infrastructure," providing a crucial array of data on network demand, performance, reliability, and security. "Digital Infrastructures" presents an interdisciplinary analysis of the technological systems that envelop these networks. The book balances analyses of specific civil and environmental infrastructures with broader policy and management issues, including the challenges of using IT to manage these critical systems under crises conditions. "Digital Infrastructures" addresses not only the technological dimension but, importantly, how social, organizational and environmental forces affect how IT can be used to manage water, power, transport and telecommunication systems. The book is organized four sections. First, fundamental themes of policy, management, and technology are presented to frame the domain of digital infrastructures. Second, the way in which information technologies are applied in specific infrastructure sectors provides an in-depth assessment of what the advantages and disadvantages have been over time. Third, cross-cutting themes of economics, earth systems engineering, and international sustainability show how various systems perspectives approach some of the barriers to integrating information technology and infrastructure. Finally, the concluding section looks at some of the new directions and challenges being posed by issues such as security. "Digital Infrastructures" is the first integrated treatment of how IT technology is fundamentally affecting how critical infrastructures are managed. It is geared to provide the new infrastructure professional with state of the art concepts, methods, and examples for use in creating public policies, strategic plans, and new systems. It will be an essential book for upper level undergraduate and graduate courses in infrastructure management, critical infrastructure, environmental systems management, and management of IT systems.

In a world that continues to increase in size and complexity, the dependence on information technologies (IT) that drive our life support systems is growing rapidly. Few other technologies have spread as rapidly. This book addresses the pervasive influence that IT has had on infrastructure, namely transportation, water supply and wastewater management, energy, and telecommunications, and its users. This is especially timely in light of the growing need for critical policy, management and technological choices about the reliability and security of IT and infrastructure systems, and in particular what was deemed critical infrastructure by the President's Commission on Critical Infrastructure Protection in 1997 (US Department of Commerce, Critical Infrastructure Assurance Office 1997) and again in 2003 by the White House (White House 2003).

After the terrorist attacks on the World Trade Center in New York City on September 11, 2001, the ability to rapidly restore transportation, power, water, and environmental services to users was absolutely critical, especially to those involved in the immediate search, rescue, and recovery operations. What better way could infrastructure serve its users-both emergency workers and the general public-than to be able to respond quickly in a crisis? The ability to provide these services required a degree of flexibility, often unanticipated and unplanned, that only became apparent as the response efforts unfolded. The capability of basic infrastructure service providers to respond to public needs for transportation, energy, communication, water, sanitation, and solid waste removal after the September 11th attacks was to a great extent influenced by the flexibility of the initial infrastructure design and management functions to respond to normal system disruptions and to extreme, but not necessarily terrorist-related, events.

Over the last decade, the development and operation of conventional infrastructure, such as transportation, water and power systems, has increasingly become dependent on information technologies (IT). Due to the rapid rate of advances in IT, especially compared to the rate of
infrastructure advances, the examination of its impacts and potential benefits for other infrastructure have not been fully examined or understood. Civil infrastructure research and IT research have largely advanced along separate paths, and although the connections and interdependencies are more apparent now than ever, no comprehensive agenda for merging these research areas exists. This is the context in which the idea for a National Science Foundation funded workshop emerged. The Institute for Civil Infrastructure Systems (ICIS) at New York University organized and led, "Bringing Information Technology to Infrastructure: A Workshop to Develop a Research Agenda," as a starting place to identify research that would bring IT and infrastructure research closer together.

Urbanized and soon-to-be urbanizing areas are increasingly dependent upon infrastructure transmission and distribution networks for the provision of essential public resources and services for transportation, energy, communications, water supply, and wastewater collection and treatment. In large part, the increasing spread of population settlements at the periphery of cities and the increasing density and vertical integration of urban cores have increased reliance upon the connectivity that these networks provide. These infrastructure networks are, in turn, dependent upon one another, both functionally and spatially, in very complex ways, and that interdependence is increased as new capacity-enhancing infrastructure technologies are developed. The extent of these dependencies appears to be escalating, and that results in interactions among the systems and produces effects upon environments that are difficult to predict.

This comparative scorecard for the New York Metropolitan region - an area which stretches from Waterbury, CT to Trenton, NJ - presents 36 indicators covering eight categories of economic and social well-being. How does New York's current condition compare to that of other large metropolitan areas, and how does New York's performance in the last five years compare to that of these other areas? The 12 metropolitan areas to which New York is compared are: Boston, Chicago, Dallas, Detroit, Houston, Los Angeles, Philadelphia, Phoenix, San Antonio, San Diego, San Francisco, and Washington, DC.

In this article, we focus on the distributional impact of a shift to charging for water and sewer service based entirely on actual water use measured by meters. In particular, we examined what the impact of universal metering in New York City would be on low- and moderate- income housing. We found that, despite its possible positive effects on conservation, universal water metering would have a substantial and regressive impact on both the providers and consumers of the city's low-income housing.

The basic facts are increasingly well-known. Young children (under 6 years of age) have the highest poverty rates of any age group in the United States (Shirk, Bennett, & Aber, 1999) and in most other major Western industrialized democracies (Rainwater & Smeeding, 1995). In addition, poverty experienced in early childhood, especially extreme poverty, is more detrimental to children's future development than poverty experienced later in life (Duncan, Brooks-Gunn, & Klebanov, 1994). And, although it is difficult to tease out the effects of family-level poverty compared to that of neighborhood-level poverty, when researchers do so, it appears that family-level poverty has the stronger influence on children's development, including their mental health (Aber, 1994; Brooks-Gunn, Duncan & Aber, 1997).

Water pollution from agricultural pesticides continues to be a public concern. Given that the use of such pesticides on the farm is largely governed by voluntary behavior, it is important to understand what drives farmer behavior. Health belief models in public health and social psychology argue that persons who have adverse health experiences are likely to undertake preventive behavior. An analogous hypothesis set was tested here: farmers who believe they have had adverse health experiences from pesticides are likely to have heightened concerns about pesticides and are more likely to take greater precautions in dealing with pesticides. This work is based on an original survey of a population of 2700 corn and soybean growers in Maryland, New York, and Pennsylvania using the U.S. Department of Agriculture data base. It was designed as a mail survey with telephone follow-up, and resulted in a 60 percent response rate. Farm operators report experiencing adverse health problems they believe are associated with pesticides that is equivalent to an incidence rate that is higher than the reported incidence of occupational pesticide poisonings, but similar to the reported incidence of all pesticide poisonings. Farmers who report experiencing such problems have more heightened concerns about water pollution from fertilizers and pesticides, and illness and injury from mixing, loading, and applying pesticides than farmers who have not experienced such problems. Farmers who report experiencing such problems also are more likely to report using alternative pest management practices than farmers who do not report having such problems. This implies that farmers who have had such experiences do care about the effects of application and do engage in alternative means of pest management, which at least involve the reduction in pesticide use.

This paper investigates the effects of information from different sources on farmers' attitudes regarding the effects of pesticides and other agricultural chemicals on environmental quality using a survey of 2700 farmers in three mid-Atlantic states. Farmers' beliefs are similar to those of the general public on average, but are distributed more uniformly, suggesting that the farm community may be more polarized on environmental issues than the general public. Farmers regard first-hand sources of information such as direct field observation and pesticide labels as being the most important. Chemical dealers and extension rank next in importance. Farmers who attached greater importance to information from news media and extension expressed greater environmental concern. Farmers who found information from chemical dealers more important expressed greater concern about injury to wildlife and pesticides in drinking water but less concern about general environmental quality problems associated with agricultural chemicals.

The effectiveness of current groundwater protection policies depends largely on farmers' voluntary compliance with leaching reduction measures, an important component of which is their willingness to adopt costlier production practices in order to prevent leaching of chemicals. Data from an original survey of 1611 corn and soybean growers in the mid-Atlantic region were used to estimate farmers' willingness to pay to prevent leaching of pesticides into groundwater. The results indicate that farmers are willing to pay more for leaching prevention than nonfarm groundwater consumers, both absolutely and relative to total income. The primary motivation appears to be concern for overall environmental quality rather than protection of drinking water or the health and safety of themselves and their families. Hobby farmers are willing to pay more than farmers with commercial activity. Certified pesticide applicators are willing to pay less than farmers without certification.

In recent years, developing countries under fiscal pressure have increasing recognized significant weaknesses in their intergovernmental mechanisms for financing local infrastructure. Many countries are in the process of rationalizing poorly coordinated and subjectively allocated grant systems as well as loans. Such efforts, however, are typically undertaken independently of each other, often providing conflicting incentives for local fiscal behavior. I argue that the reform of grant and loan mechanisms should be explicitly linked to improve the overall effectiveness of the infrastructure finance system. The potential complications involved in designing grant-loan linkages, however, are considerable. I illustrate some key issues by examining the water sector in Indonesia, concluding with suggestions for how to think about creating such linkages in other sectors and countries.
