Occupational exposure to aerosolized particles of oil-basedmetalworking fluid was recently linked to deaths from ischemic heart disease. The current recommended exposure limits might be insufficient. Studying cardiovascular mortality is challenging because symptoms can induce sicker workers to reduce their exposure, causing healthyworker survivor bias.

A critical review of studies examining exposures to the various forms of silver was conducted to determine if some silver species are more toxic than others. The impetus behind conducting this review is that several occupational exposure limits and guidelines exist for silver, but the values for each depend on the form of silver as well as the individual agency making the recommendations. For i...

Background: The aim of this study was to calculate the radiation amount exposed during percutaneous nephrolithototomy (PCNL) and to make the urologists and other staff sensitive about the radiation risk they were exposed to. Materials and Methods: We measured the radiation exposure during 114 cases of PCNL performed. Thermoluminescent dosimeters (TLD) were placed between the operation table and...

An assessment of exposure to glutaraldehyde in cold sterilisation and x ray development processes was undertaken in 14 locations at six hospitals in south east England. The results obtained indicate that routine exposures of hospital workers to airborne concentrations of the compound are within the current United Kingdom occupational exposure limit of 0.7 mg m-3. There was the potential for ski...

exposure to pesticides could be one of the contributing cause to the falling sperm counts and rising levels of male infertility. adverse effects of pesticides in the environment first received widespread attention in the 1960s. however, only recently it has been postulated that long term, low exposure of these chemicals are increasingly linked to human health effects such as immuno-suppression,...
