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 ...

Exposure assessment and analysis for biological agents

Grana, 2004
Airborne biological agents have become prominent safety and health issues in agriculture, biotechnology, industrial settings, and the indoor environment. Each of these environments presents unique exposure concerns due to the nature of the encountered biological agent, the microbial concentrations, the modes of exposure, and the susceptibility of the ...

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.

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.

Inhalable dust as a marker of exposure to airborne biological agents in composting facilities.

Waste Management, 2018
OBJECTIVES Industrial composting is associated with high levels of worker exposure to bioaerosols. Measurement of airborne microorganisms and endotoxin is complex and the related cost is high.

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.

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 ...
