Toxicology is the study of how natural or man-made poisons cause undesirable effects in living organisms.
Pollution Linked to Hospitalizations for Pneumonia in Older AdultsOlder adults with long-term exposure to higher levels of pollution are at higher risk for hospitalization for pneumonia
Hidden threat: Elevated pollution levels near regional airportsScientists are reporting evidence that air pollution — a well-recognized problem at major airports — may pose an important but largely overlooked health concern for people living near smaller regional airports.
People vary widely in ability to eliminate arsenic from the bodyLarge variations exist in peoples’ ability to eliminate arsenic from the body, according to a new study that questions existing standards for evaluating the human health risks from the potentially toxic substance.
Surprising new health and environmental concerns about tungstenSurprising new scientific research is raising concerns about the potential health and environmental hazards of tungsten — a metal used in products ranging from bullets to light bulbs to jewelry
Pesticide Concentrations DecreasingA new USGS study, published in the Journal of Environmental Quality, shows encouraging results in evaluating groundwater contaminants.
Newly approved pesticide stirs controversy over health effectsRegulators in California and other states are taking a closer look at the substance’s potential adverse health effects before allowing the chemical to be used
Pesticides Persist in Ground WaterUSGS scientists examine factors influencing pesticide detection in ground water in the May-June issue of Journal of Environmental Quality.
High Cholesterol Levels And Chronic Exposure To Toxigenic Molds In Damp Buildings: A High Risk For Cardiovascular Diseases And StrokeEpidemiological evidence suggests a possible association between chronic exposures to toxigenic molds in damp water-damaged buildings and high levels of cholesterol abnormalities that may represent a high risk for cardiovascular diseases.
Oral Fluid in ToxicologyThis article reviews role of saliva in toxicology.
Urine Phenol Level Among Healthy Subjects In Urban AreaPhenol can be found at high levels in the traffic area, therefore, people living in the urban area of big city are highly exposed to traffic phenol vapor.
An examination of knowledge, attitudes and practices related to lead exposure in South Western NigeriaIn this study, the authors conducted several focus group discussions with adult residents of Ibadan to evaluate their knowledge, attitudes and practices with respect to chronic low-dose domestic lead exposure and its effect on health
Description of industrial pollution in SpainThe aim of this paper is to describe industrial air and water pollution in Spain in 2001, broken down by activity group and specific pollutant, and to plot maps depicting emissions of carcinogenic substances
Evaluation of land farming and chemico-biological stabilization for treatment of heavily contaminated sediments in a tropical environmentConventional and experimental methods were studied for the remediation of petroleum contaminatedsediments from a dam previously used to collect acid run-off from a sulfur mine.
Radioactive waste – no problem for metal-munching bacteriaA harmless soil bacterium, which can survive high-level exposures to gamma radiation, is being developed to clean up land contaminated with radioactive waste
DDT In Mothers' Blood Predicts Delays In Daughters' Pregnancies (p 2205)A research letter in this week's issue of THE LANCET reports on the effect of the pesticide DDT and its by-product, DDE, on female reproductive capability
