Air quality levels vary over regions due to meteorological factors, proximity to sources, and local conditions (i.e., topography). The Northeast USA is subjected to pollution inputs from both local sources and those from the upwind Midwest USA that are transported by prevailing meteorological patterns. With the passage of the Clean Air Act in 1970 and the establishment of the National Ambient A...

BACKGROUND Air quality degraded by black smoke (particulate matter, PM10), sulphur dioxide (SO2) and nitrogen oxide (NO(x)) affects human health. Improvements following national legislation have lowered death rates. Whether background air pollution levels continue to affect human health remains unclear. AIM To determine impact of air pollutant concentrations (PM10, SO2 and NO(x)) on in-hospit...

et al. Correcting serum concentrations of organochlorine compounds by lipids: alternatives to the organochlorine/total lipids ratio. Evaluation of total lipids using enzymatic methods for the normalization of persistent organic pollutant levels in serum.

the goal of this research is to study the effect of benzo-alpha-pyrene (bαp) as a pollutant on the plasma levels of cortisol, thyroxin (t4), and triiodothyronine (t3) hormones, and the t3/t4 ratio in the yellowfin sea bream, acanthopagrus latus. the bαp (50 mg kg-1) in vegetable oil was peritoneally injected. blood samples were obtained from the treated and control groups after 3 and 72 hr, res...

In this paper, we assume that a professional pollutant treatment enterprise treats all of the pollutants emitted by multiple small and medium-sized enterprises (SMEs). In order to determine the treatment price, SMEs can bargain with the pollutant treatment enterprise individually, or through forming alliances. We propose a bargaining game model of centralized pollutant treatment to study how th...

This study was undertaken to determine whether there was a correlation between fine particles (PM2.5) levels and hospital admissions for ischemic heart disease (IHD) in Taipei, Taiwan. Hospital admissions for IHD and ambient air pollution data for Taipei were obtained for the period from 2006–2010. The relative risk of hospital admissions was estimated using a case-crossover approach, controlli...
