Residential exposure can dominate total exposure for commercial chemicals of health concern; however, despite the importance of consumer exposures, methods for estimating household exposures remain limited. We collected house dust and indoor air samples in 49 California homes and analyzed for 76 semivolatile organic compounds (SVOCs)--phthalates, polybrominated diphenyl ethers (PBDEs), polychlo...

A viable virus aerosol sampler (VIVAS) effectively collected viable influenza A and B viruses from air inside a student health care center during an influenza outbreak. The viruses had "drifted" genes, showcasing the usefulness of the VIVAS for air sampling and noninvasive surveillance of viruses in circulation.

Many ailments can be linked to exposure to indoor airborne fungus. However, obtaining a precise measurement of airborne fungal levels is complicated partly due to indoor air fluctuations and non-standardized techniques. Electrostatic dust collector (EDC) sampling devices have been used to measure a wide range of airborne analytes, including endotoxins, allergens, β-glucans, and microbial DNA in...

swelling urban populations and increasing number of industry and especially automobiles in and around cities have resulted in adverse effect on human health. one of the most important things regarding air pollution in these days is that the number of motor vehicles has increased, and the resulting problems of new types of air pollution on large scale need to be emphasized in large cities.the gr...

introduction: toluene is an organic solvent that it is one of the byproducts in the coke industry. exposure to toluene causes central nervous system dysfunction and others disorders. many workers are exposed to toluene due to leakage from tracks. therefore the aim of this study was to determine the levels of exposure through environmental and biological monitoring of toluene methods: air toluen...

COLEBROOK (1946) has shown that the provision of clean air, especially in operating theatres and dressing rooms, is an essential condition for the prevention of wound infection. To achieve this it is necessary to have an adequate and controlled ventilation rate and the air introduced should be free from bacteria. Such conditions are being provided in modern operating theatres but in most hospit...
