    The most significant conclusion from this work is that the rate of accumulation of pariculate matter within the BZ is strongly dependent upon the distance between the contaminant source and the body. The results also suggest that particle concentration levels within the BZ may also rely heavily on source distance; however, it is impossible to draw ...

    We appreciate Dr. Watine's concern because combined carbon monoxide (CO) and cyanide intoxications can occur in victims of fire smoke inhalation. Like CO, hydrogen cyanide (HCN) is often a product of combustion in fires and is a hazard to firefighters and fire victims. HCN in structural fires typically is produced by the combustion of synthetic pol ...

    Ramachandran G
    2000/06/01 | Grant Final Reports
    A variety of health effects are caused by chronic, cumulative exposure over time to pollutants. In these cases, to establish dose-response relationships for epidemiological and risk assessment purposes, it is vital to determine the exposures of individuals or cohorts as functions of time. Most existing occupational exposure databases, however, do n ...

    Two major proficiency testing programs in the industrial hygiene field are compared with regard to their power to detect laboratories having a large bias and poor precision. Although the two programs are similar in many aspects, such as the analytes tested, frequency of test rounds, and number of samples used in each test round, their evaluation pr ...
