Studies examining the nonfatal health outcomes of exposure to air pollution have been limited by number pollutants studied and focus on short-term exposures.We examined relationship between long-term fine particulate matter with an aerodynamic diameter <2.5 micrometers (PM2.5), NO2, tropospheric ozone hospital admissions for 4 cardiovascular respiratory (myocardial infarction, ischemic stroke, atrial fibrillation flutter, pneumonia) among Medicare population United States. We used a doubly...

The environmental consequences of electric vehicles (EV) have been extensively studied, but the literature on their health impacts is scant. At same time, fine particulate matter (PM2.5), for which transportation a major source, remains an important public issue in United States. Motivated by recent developments epidemiology and reduced-form air pollution modeling, as well reductions power plant emissions, we conduct updated assessment benefits light-duty vehicle electrification large...

Significance On-road vehicles have become a significant source of air pollution in Chinese cities. Air China has substantial impacts on public health and is thought to be responsible for millions deaths each year. The government implemented comprehensive control measures mitigate vehicle emissions since the late 1990s. In this paper, we analyze how historical actions during 1998–2015 affected quality health. We constructed an integrated framework combining emission scenarios, modeling,...

IN SOME OF THE EARLIEST STUDIES on ovarian hormones the assay methods were based growth of uteri in normal or castrated immature rabbits, rats, mice (i, 2). No detailed study this reaction rats was made until Astwood and others (3, 4) determined most favorable experimental conditions for a sensitive estrogen test an increase uterine weight. They showed that method is much more than spayed rat vaginal smear method. However, weight response albino mouse to gonadotropins uniform (5–9). These...

BackgroundLong-term exposure to air pollution has been linked with an increase in risk of mortality. Whether existing US Environmental Protection Agency standards are sufficient protect health is unclear. Our study aimed examine the relationship between lower concentrations and mortality.MethodsOur nationwide cohort investigated effect annual average pollutants on all-cause mortality among Medicare enrolees from beginning 2000 end 2016. Patients entered month January following enrolment were...

Abstract Based on imperfect data and theory, agencies such as the United States Environmental Protection Agency (USEPA) currently derive "reference doses" (RfDs) to guide risk managers charged with ensuring that human exposures chemicals are below population thresholds. The RfD for a chemical is typically reported single number, even though it widely acknowledged there significant uncertainties inherent in derivation of this number. In article, authors propose probabilistic alternative EPA's...

Exposure to fine particulate matter (PM2.5) from indoor and outdoor sources is a leading environmental contributor global disease burden. In response, we established under the auspices of UNEP/SETAC Life Cycle Initiative coupled indoor-outdoor emission-to-exposure framework provide set consistent primary PM2.5 aggregated exposure factors. We followed matrix-based mass balance approach for quantifying ground-level urban rural using an effective population intake fraction system archetypes...

Significance Despite decades of reductions in vehicle emissions the United States, their impacts remain large, and offsetting effects different factors on benefits achieved recent years are not well understood. We assess from 2008 to 2017 a fine spatial resolution using latest epidemiological evidence inventories. find that regulation continues yield large benefits: $270 (190 480) billion reduced PM 2.5 -attributable mortality greenhouse gas emissions.

Interest in examining both the uncertainty and variability environmental health risk assessments has led to increased use of methods for propagating uncertainty. While a variety approaches have been described, advent powerful personal computers commercially available simulation software Monte Carlo simulation. Although most analysts regulators are encouraged by these developments, some concerned that analysis is being applied uncritically. The validity any contingent on inputs analysis. In...
