This project was conducted by the Pollution Prevention Research Branch(PPRB) of the U.S. Environmental Protection Agency(EPA) with the cooperation of Union Carbide Corporation, Nordson Corporation , and the Pennsylvania House Furniture Company. The PPRB is evaluating and demonstrating new technologies for pollution prevention through the Pollution Prevention Clean Technology Demonstration (CTD)...
Tobacco smoke air pollution (TSAP) measurement may persuade parents to adopt smoke-free homes and thereby reduce harm to children from tobacco smoke in the home. In a pilot study involving 29 smoking families, a Sidepak was used to continuously monitor home PM(2.5) during an 8-h period, Sidepak and/or Dylos monitors provided real-time feedback, and passive nicotine monitors were used to measure...
In December 1968, during its annual meeting, the American Association for the Advancement of Science convened a symposium on the Global Effects of Environmental Pollution. In the words of the organizer of this symposium, Mr. S. Fred Singer, the purposes "were to discuss the worldwide effects which may arise from local pollution and to try to uncover, if possible, hitherto unsuspected effects wh...
This paper addresses the existence of an Environmental Kuznets Curve for China, using a sample of 30 regions, covering the period 1982–1997. The types of pollution included are wastewater, waste gas, and solid waste. We consider the development of the sources of pollution in a pooled cross-section analysis with pollution in absolute levels, in per capita terms, and relative to real Gross Region...
Moderate e ects of pollution on health may exert an important in uence on labor market decisions. We exploit exogenous variation in pollution due to the closure of a large re nery in Mexico City to understand how pollution impacts labor supply. The closure led to an 8 percent decline in pollution in the surrounding neighborhoods. We nd that a one percent increase in sulfur dioxide results in a ...
While there are extensive theoretical studies on firms’ responses to environmental regulations and enforcement, there are few empirical analyses of firms’ expenditures on pollution abatement in responding to different regulations and enforcement strategies. This paper presents an empirical analysis of pollution abatement efforts of Chinese industrial firms under a combination of pollution charg...
This paper introduces a new real-time air pollution alert system using mobile devices. Through the location awareness capability of mobile devices, Androidand iOS-based apps are developed to inform the public residing in the vicinity of air pollution areas. The apps have shown to be working successfully sending push notifications as well as a regional map to convey the air pollution information...
This study examines the air pollution control structure for the Las Vegas Valley. A System Dynamics computer model was created that represents the structure of the real world system for controlling air pollution, in order to examine how the current air pollution control system might behave in the future.
BACKGROUND Olfactory dysfunction affects millions of people worldwide. This sensory impairment is associated with neurodegenerative disease and significantly decreased quality of life. Exposure to airborne pollutants has been implicated in olfactory decline, likely due to the anatomic susceptibility of the olfactory nerve to the environment. Historically, studies have focused on occupational ex...
Traffic-related air pollution and obesity formation in children: a longitudinal, multilevel analysis
BACKGROUND Biologically plausible mechanisms link traffic-related air pollution to metabolic disorders and potentially to obesity. Here we sought to determine whether traffic density and traffic-related air pollution were positively associated with growth in body mass index (BMI = kg/m2) in children aged 5-11 years. METHODS Participants were drawn from a prospective cohort of children who liv...
