More than 60,000,000 Bangladeshis are drinking water with unsafe concentrations of one or more elements. The aim of this study was to evaluate and improve the drinking water testing and treatment plans for western Bangladesh.

Diesel exhaust particles (DEPs) are globally relevant air pollutants that exert a detrimental human health impact. However, mechanisms of damage by DEP exposure to human respiratory health and human susceptibility factors are only partially known.

Traffic-related air pollution has been associated with adverse health outcomes, and the immune system may be a biologic mediator of health effects. We analyzed associations between living near major roads and immune status as measured

Methylmercury (MeHg), a worldwide contaminant found in fish and seafood, has been linked to an increased risk of cardiovascular mortality. The researchers examined 42 Faroese whaling men (30

Epidemiologic studies suggest a positive association between fine particulate matter and arterial blood pressure, but the results have been inconsistent. The researchers investigated the effect of ambient particles on systemic hemodynamics during a 5-hr exposure to concentrated ambient air particles (CAPs) or filtered air (FA) in conscious canines.

Arsenic exposure is associated with human cancer. Telomerase-containing human telomerase reverse transcriptase (hTERT) can extend telomeres of chromosomes, delay senescence, and promote cell proliferation leading to tumorigenesis. The goal of this study was to investigate the effects of As on hTERT mRNA expression in humans and in vitro.

Mixtures of organophosphate and carbamate pesticides are commonly detected in freshwater habitats that support threatened and endangered species of Pacific salmon (Oncorhynchus sp.) . These pesticides inhibit the activity of acetylcholinesterase (AChE) and thus have potential to interfere with behaviors that may be essential for salmon survival.

A smoking law was passed by the Spanish Parliament in December 2005 and was enforced by 1 January 2006. The law bans smoking in all indoor workplaces but only in some hospitality venues, because owners are allowed to establish a smoking zone (venues > 100 m2) or to allow smoking without restrictions (venues

During the last decade, mobile phone use increased to almost 100% prevalence in many countries of the world. Evidence for potential health hazards accumulated in parallel by epidemiologic investigations has raised controversies about the appropriate interpretation and the degree of bias and confounding responsible for reduced or increased risk estimates.

Regulatory bodies worldwide are charged with making major decisions related to chemical toxicology, such as designation of toxic thresholds and establishment of criteria for preclinical testing and toxic hazard classification.
