Biological markers of exposure to organophosphorus nerve agents

Archives of Toxicology, 2013
Organophosphorus nerve agents are the most toxic chemical warfare agents that are known to have been produced, stockpiled and weaponised. Their development, production, stockpiling and use are prohibited under the terms of the Chemical Weapons Convention and, together with their precursors, are subject to strict controls and verification procedures ...

Urinary mercapturic acid excretion as a biological parameter of exposure to alkylating agents

International Archives of Occupational and Environmental Health, 1977
Mercapturic acid derivatives or other thioethers can be considered as the endproducts of the metabolic detoxification of possibly alkylating agents. It is proposed that the appearance of these metabolites in the urine can be used as an indicator of exposure of the organism to such toxic compounds.

Airborne exposure limits for chemical and biological warfare agents: Is everything set and clear?

International Journal of Environmental Health Research, 2006
Emergency response strategies (guidelines) for biological, chemical, nuclear, or radiological terrorist events should be based on scientifically established exposure limits for all the agents or materials involved. In the case of a radiological terrorist event, emergency response guidelines (ERG) have been worked out.

Validity criteria for the use of biological markers of exposure to chemical agents in environmental epidemiology

Toxicology, 1995
Biomarkers may prove very useful in increasing the precision of exposure estimates during field epidemiological studies of environmental and occupational exposures. However, the determination of validity of exposure biomarkers is a laborious process.

Aerobiology and Inhalation Exposure to Biological Select Agents and Toxins

Veterinary Pathology, 2010
Aerosol is the most likely route of dissemination of biological select agents and toxins in a bioterrorist attack, regardless of the natural route of exposure to the agent. The use of animal models for testing preventative and therapeutic countermeasures requires knowledge of the pathogenesis of disease after inhalation exposure.

Working Group Report 4: Exposure assessment for biological agents

American Journal of Industrial Medicine, 2004
AbstractThis Working Group was assembled to review and evaluate methods currently used to estimate work site exposures to biological agents and to present recommendations on suitable measurement strategies. The current state of exposure assessment was evaluated for environments with organic dust including agriculture, composting, sewage and waste ...

Biological considerations in assessing exposures to genotoxic and carcinogenic agents

International Archives of Occupational and Environmental Health, 1993
This analysis of the relationship between long-term exposure to carcinogens and the risk of cancer relies upon a model which depicts exposure, burden and genetic damage as time series. It is shown that the dose of the carcinogen and the resulting damage to susceptible tissues can be related to cumulative exposure provided that linear kinetics are ...

Exposure assessment in Beijing, China: biological agents, ultrafine particles, and lead

Environmental Monitoring and Assessment, 2009
In this study, air samples were taken using a BioSampler and gelatin filters from six sites in Beijing: office, hospital, student dormitory, train station, subway, and a commercial street. Dust samples were also collected using a surface sampler from the same environments.

Belief in Exposure to Chemical and Biological Agents in Persian Gulf War Soldiers

Journal of Nervous & Mental Disease, 2008
This is the first longitudinal cohort study of Persian Gulf War US soldiers to examine belief in exposure to chemical and biological weapons before and shortly after combat. A longitudinal sample of n = 1250 male Persian Gulf War US Army soldiers were surveyed 3 to 4 months before and 6 to 10 months after the 1991 War.
