Pollution loads discharged from upstream development or human activities significantly degrade the water quality of a reservoir. The design of an appropriate water quality sampling network is therefore important for detecting potential pollution events and monitoring pollution trends. However, under a limited budgetary constraint, how to site an appropriate number of sampling stations is a chal...

Air pollution is responsible for many health problems in the urban areas. Of late, the air pollution status in Delhi has undergone many changes in terms of the levels of pollutants and the control measures taken to reduce them. This paper provides an evidence-based insight into the status of air pollution in Delhi and its effects on health and control measures instituted. The urban air database...

Outdoor and indoor air pollution poses a significant cardiovascular risk, and has been associated with atherosclerosis, the main underlying pathology in many cardiovascular diseases. Although, it is well known that exposure to air pollution causes pulmonary disease, recent studies have shown that cardiovascular health consequences of air pollution generally equal or exceed those due to pulmonar...

This study assessed the public's health risk awareness of urban air pollution triggered by three megacities in China, and the data are the responses from a sample size of 3868 megacity inhabitants from Shanghai, Nanchang and Wuhan. Descriptive analyses were used to summarize the respondents' demographics, perceived health risks from air pollution and sources of health-related knowledge on urban...

Pollution: Associations Persist with Continued Advances in Research Methodology (See Neas et al., p. 629; Lee and Schwartz; p. 633; and Fairley, p. 637) In this issue of Environmental Health Perspectives there are papers by Fairley, Neas et al., and Lee and Schwartz. Although these papers present different approaches, they provide a reasonable representation of stateof-the-art epidemiologic res...

BACKGROUND Air pollution is increasingly documented as a threat to public health in most developing countries. Evaluation of current air quality levels, regulatory standards and scientific literature on outdoor and indoor air pollution, and health effects are important to identify the burden, develop and implement interventions and to fill knowledge gaps in Sri Lanka. METHODS PUBMED and Medli...

China’s socioeconomic transitions have dramatically accelerated its economic growth in last three decades, but also companioned with continuous environmental degradation. This study will advance the knowledge of heavy metal water pollution in China from a spatial–temporal perspective. Specifically, this study addressed the following: (1) spatial patterns of heavy metal water pollution levels we...

A pervasive problem in the literature on the health costs of pollution is that optimizing individuals may compensate for increases in pollution by reducing their exposure to protect their health. This implies that estimates of the health effects of pollution may vastly understate the full welfare effects of pollution, particularly for individuals most at risk who have the greatest incentive to ...

The Tibetan Plateau is described as the "Roof of the World" averaging over 4000 m above sea level; it is remote, isolated, and presumed to be a pristine region. In order to study the history of atmospheric mercury (Hg) pollution and its spatial variation across the Plateau, lakes were chosen from three areas forming a north to south transect. Sediment cores were taken from three sites in each a...

Pollution charges exist in various forms, as described in Box 1. They can be imposed on emissions or products; they can be levied as a fee for service or as a fine for noncompliance; and they can be collected as separate payment or as part of a broader levy, such as a locally defined water use tariff or national energy tax. Pollution charges can be levied on actual source emissions (direct emis...
