Accumulating evidence suggests that outdoor air pollution may have a significant impact on central nervous system (CNS) health and disease. To address this issue, the National Institute of Environmental Health Sciences/National Institute of Health convened a panel of research scientists that was assigned the task of identifying research gaps and priority(More)
This study examined the fate of indicator organisms (fecal coliform, E. coli, and enterococci) from urban stormwater runoff associated with estuarine sediments and stormwater suspended particles. The research found a significant increase of fecal coliform, E. coli, and enterococci in the estuarine sediments at study sites following a given stormwater event.(More)
The objective of the cross-sectional study was to assess whether exposure to polycyclic aromatic hydrocarbons (PAHs) from coke oven emissions contributed to alteration of semen quality and sperm DNA integrity in nonsmoking workers. Nonsmoking coke oven workers from a steel plant in Taiwan served as the exposure groups (topside-oven workers for the high(More)
The objective of this study was to evaluate the association of cigarette smoking with semen quality and reproductive hormone levels in 192 healthy men 20-65 years old, Kaohsiung, Taiwan. Exposure to cigarette smoking was classified three ways based on: 1) smoking status (yes vs. no); 2) the number of cigarettes per day (0, 1-10, > 10); and 3) pack-years (0,(More)
Along with existing and emerging use of nanoscale materials, growing concerns have arisen about their unintentional health and environmental impact. The objective of the ongoing study was to assess the toxicity profile of metal oxide nanoparticles proposed for use in industrial production methodology. Metal oxide nanoparticles used in this study included(More)
Endocrine disrupting chemicals (EDCs) can interfere with normal hormonal balance and may exert adverse consequences on humans. The male reproductive system may be susceptible to the effects of such environmental toxicants. This review discusses the recent progress in scientific data mainly from epidemiology studies on the associations between EDCs and male(More)
The objective of this study was to assess whether polycyclic aromatic hydrocarbons (PAHs) affect male reproductive functions in vivo. Male reproductive parameters included testis weight, sperm counts and motility, circulating follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone. The average body weight, testis weight, and(More)
SARS (Severe Acute Respiratory Syndrome) is a newly emerging infectious disease which spread over 32 countries and areas, infected more than 8,000 people and causing more than 900 deaths from November 2002 to August 2003. More than 90% of the SARS cases and death were reported from China. Nevertheless, we still know little about this disease, particularly(More)
OBJECTIVES We evaluated the association between exposure to polycyclic aromatic hydrocarbons (PAHs) and immunological measurements using blood samples from coke oven workers exposed to high and low PAH levels. METHODS A population-based cross-sectional study was conducted from 2008-2009 with coke oven workers and steel-rolling workers as the exposed and(More)
