This book was released on 2004-10-22 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, the U.S. Environmental Protection Agency (EPA) established regulatory standards to address health risks posed by inhaling tiny particles from smoke, vehicle exhaust, and other sources. At the same time, Congress and the EPA began a multimillion dollar research effort to better understand the sources of these airborne particles, the levels of exposure to people, and the ways that these particles cause disease. To provide independent guidance to the EPA, Congress asked the National Research Council to study the relevant issues. The result was a series of four reports on the particulate-matter research program. The first two books offered a conceptual framework for a national research program, identified the 10 most critical research needs, and described the recommended timing and estimated costs of such research. The third volume began the task of assessing initial progress made in implementing the research program. This, the fourth and final volume, gauged research progress made over a 5-year period on each of the 10 research topics. The National Research Council concludes that particulate matter research has led to a better understanding of the health effects caused by tiny airborne particles. However, the EPA, in concert with other agencies, should continue research to reduce further uncertainties and inform long-term decisions.
Download or read book Quantification of Carbonaceous Pollutants from On road Vehicles at Selected Inner city Settings written by Jiangchuan Hu and published by . This book was released on 2012 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic-related air pollutants are under great emphasis with the increasing traffic volume in recent years. In this study, traffic-related air pollutants are investigated at a busy urban intersection and a parking garage in Cincinnati, Ohio. These two settings are representative of typical inner-city environments with frequent and concentrated activities and thus substantial human exposure. Ambient concentrations of black carbon (BC), organic carbon (OC), elemental carbon (EC), carbon monoxide (CO), and ultrafine particles (UFP), were monitored and related to traffic patterns, volume, delay, and meteorology at the intersection in four seasons throughout years 2009-2011. The same air pollutant constituents also were characterized for a public parking garage during some special events. At the traffic intersection, concentrations of the air emissions were measured and the seasonal and diurnal trends of the emissions were observed. Air concentrations were highest during the fall season and lowest during winter. Air emission concentrations were found to be highest during the AM periods, compared with noon and PM periods, but no significant differences between the noon and PM sampling periods were found. In the measurement of light-absorbing carbon (EC or BC) in particular, two aethalometers consistently agreed with each other during the sampling periods. Concentrations of BC and EC were compared to investigate the agreement between two different monitoring methods, the continuous measurement and the intermittent (time-integrated filter) measurement. A consistent 30-35% increase was observed for BC over EC. Relationships between air emission concentrations and traffic and meteorology factors were investigated. Black carbon concentrations were found to be positively associated with the volume of heavy-duty vehicles in 85% of the measurements. Carbon monoxide and ultrafine particles were found to be positively associated with the volume of total traffic in about 70% of the measurements. Ultrafine particle concentrations increased by about 20% when the instrument was placed at a downwind location. Concentrations of UFP were 22-37% higher during AM and noon periods when the wind speed was less than 2 m/s compared to greater than 2 m/s in the fall season. In the parking garage, seven measurements inside an enclosed parking garage have been conducted since winter 2010, during special event activities. Carbon monoxide concentrations were monitored, ranging from 2.89 to 15.65 ppmv. Vehicles were recorded and found to be correlated with CO concentrations. The CO emissions were observed to accumulate to high concentrations inside the enclosed parking garage. This study reveals significant carbonaceous pollution from traffic at the two, inner-city settings. The monitored carbonaceous particulate concentrations represented the air quality during periods when large numbers of people are expected to be exposed especially during rush hours. The results from this study could help provide a better understanding the exposures due to traffic-related air pollution and thereby contribute to improved urban planning and government regulations.
Download or read book Modeling Mobile Source Emissions written by National Research Council and published by National Academies Press. This book was released on 2000-08-14 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mobile Source Emissions Factor (MOBILE) model is a computer model developed by the U.S. Environmental Protection Agency (EPA) for estimating emissions from on-road motor vehicles. MOBILE is used in air-quality planning and regulation for estimating emissions of carbon monoxide (CO), volatile organic compounds (VOCs), and nitrogen oxides (NOx) and for predicting the effects of emissions-reduction programs. Because of its important role in air-quality management, the accuracy of MOBILE is critical. Possible consequences of inaccurately characterizing motor-vehicle emissions include the implementation of insufficient controls that endanger the environment and public health or the implementation of ineffective policies that impose excessive control costs. Billions of dollars per year in transportation funding are linked to air-quality attainment plans, which rely on estimates of mobile-source emissions. Transportation infrastructure decisions are also affected by emissions estimates from MOBILE. In response to a request from Congress, the National Research Council established the Committee to Review EPA's Mobile Source Emissions Factor (MOBILE) Model in October 1998. The committee was charged to evaluate MOBILE and to develop recommendations for improving the model.

Download or read book Green Intelligence written by John Wargo and published by Yale University Press. This book was released on 2009-09-29 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in a world awash in manmade chemicals, from the pesticides on our front lawns to the diesel exhaust in the air we breathe. Although experts are beginning to understand the potential dangers of these substances, there are still more than 80,000 synthetic compounds that have not been sufficiently tested to interpret their effects on human health. Yale University professor John Wargo has spent much of his career researching the impact of chemical exposures on women and children. In this book, he explains the origins of society’s profound misunderstanding of everyday chemical hazards and offers a practical path toward developing greater “green intelligence.” Despite the rising trend in environmental awareness, information about synthetic substances is often unavailable, distorted, kept secret, or presented in a way that prevents citizens from acting to reduce threats to their health and the environment. By examining the histories of five hazardous technologies and practices, Wargo finds remarkable patterns in the delayed discovery of dangers and explains the governments’ failures to manage them effectively. Sobering yet eminently readable, Wargo’s book ultimately offers a clear vision for a safer future through prevention, transparency, and awareness.

Book excerpt: "America is addicted to oil. The diagnosis is clear, but what's the true price of dependence? Who's paying with their lives? Who's profiting? And, most importantly, what's the cure?" "Terry Tamminen, Special Advisor to California Governor Arnold Schwarzenegger, provides real answers in this indictment of the oil economy and the corporate titans that drive it. With all eyes focused on soaring prices at the pump, Tamminen reveals oil's more insidious costs: tens of billions spent annually to secure our global supply; crops ruined by petroleum pollution; cancer, asthma, and birth defects caused by car exhaust; and the list goes on. Simply living in a smog-filled city can be as dangerous as smoking half a pack of cigarettes a day." "Like big tobacco, Tamminen argues, the oil and auto industries have deceived us to line their own pockets. With tales of corporations knowingly exposing citizens to poisonous chemicals, conspiring to derail public transportation, and purposely disablng their own pollution controls, he builds a case against powerful industries." "And he shows how demanding accountability, as the public did through successful lawsuits against cigarette companies, could help pave the road to sustainable energy. Instead of subsidizing oil companies and auto makers through huge tax breaks, Tamminen proposes collecting damages and investing in clean technologies."--BOOK JACKET.
