Biomonitoring of exposure to potential mutagens and carcinogens in industrial populations. 1985

N J van Sittert, and G de Jong

Methods for monitoring exposure to potential industrial mutagens and carcinogens fall into two distinct groups. The tests in the first group measure the concentration of the substance, of its metabolites or of the products of its reaction with cellular macromolecules, in biological media. Such tests include the determination of urinary metabolites of the chemical, the measurement of nucleic-acid or protein adducts and the determination of urinary thioethers. The second group comprises assays of biological endpoints that may be the result of the organism's reaction to exposure. These endpoints include chromosomal aberrations in peripheral lymphocytes and sister chromatid exchanges. Each test has advantages and limitations that will affect its suitability for use in specific industrial situations.

UI	MeSH Term	Description	Entries
D009153	Mutagens	Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes.	Clastogen,Clastogens,Genotoxin,Genotoxins,Mutagen
D009784	Occupational Diseases	Diseases caused by factors involved in one's employment.	Diseases, Occupational,Occupational Illnesses,Disease, Occupational,Illnesse, Occupational,Illnesses, Occupational,Occupational Disease,Occupational Illnesse
D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
D002274	Carcinogens, Environmental	Carcinogenic substances that are found in the environment.	Environmental Carcinogens
D002869	Chromosome Aberrations	Abnormal number or structure of chromosomes. Chromosome aberrations may result in CHROMOSOME DISORDERS.

D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D004781	Environmental Exposure	The exposure to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals.	Exposure, Environmental,Environmental Exposures,Exposures, Environmental
D004811	Epichlorohydrin	A chlorinated epoxy compound used as an industrial solvent. It is a strong skin irritant and carcinogen.	Epichlorhydrin,Epichlorohydrin, (+-)-Isomer,Epichlorohydrin, (S)-Isomer
D004852	Epoxy Compounds	Organic compounds that include a cyclic ether with three ring atoms in their structure. They are commonly used as precursors for POLYMERS such as EPOXY RESINS.	Epoxide,Epoxides,Epoxy Compound,Oxiranes,Compound, Epoxy,Compounds, Epoxy
D005027	Ethylene Oxide	A colorless and flammable gas at room temperature and pressure. Ethylene oxide is a bactericidal, fungicidal, and sporicidal disinfectant. It is effective against most micro-organisms, including viruses. It is used as a fumigant for foodstuffs and textiles and as an agent for the gaseous sterilization of heat-labile pharmaceutical and surgical materials.
