Decontamination definition: The removal of contaminating material, such as radioactive materials, biological materials, or CHEMICAL WARFARE AGENTS, from a person or object.
Decontamination definition: To rid of contamination.
Inorganic Chemicals definition: A broad class of substances encompassing all those that do not include carbon and its derivatives as their principal elements. However, carbides, carbonates, cyanides, cyanates, and carbon disulfide are included in this class.
Inorganic Chemical definition: A broad class of substances, principally from mineral sources of non-biological origin, encompassing all those that do not include carbon and its derivatives as their principal elements.
Specialty Uses of Chemicals definition: Uses of chemicals in a research, industrial, or household setting. This does not include PHARMACOLOGIC ACTIONS.
Organic Chemicals definition: A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form.
organic chemical definition: broad class of substances containing carbon and its derivatives; many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements.
Organic Chemical definition: Molecule that contains atoms of the element carbon, usually combined with itself and with atoms of one or more other element such as hydrogen, oxygen, nitrogen, sulfur, phosphorus, chlorine, or fluorine. Excludes carbides, carbonates and carbon oxides.
Agrochemicals definition: Chemicals used in agriculture. These include pesticides, fumigants, fertilizers, plant hormones, steroids, antibiotics, mycotoxins, etc.
chemical definition: tree section heading for terms covering drugs, reagents, biomolecules, and other chemical compounds.
Chemical definition: A substance with a defined atomic or molecular structure that results from, or takes part in, reactions involving changes in its structure, composition, or properties.
chemical substance definition: A substance that is fully defined by an organic or inorganic chemical formula, includes mixtures of other chemical substances. Refine using, e.g., IUPAC codes.
Laboratory Chemicals definition: Chemicals necessary to perform experimental and/or investigative procedures and for the preparation of drugs and other chemicals.
Endocrine Disruptors definition: Exogenous agents, synthetic and naturally occurring, which are capable of disrupting the functions of the ENDOCRINE SYSTEM including the maintenance of HOMEOSTASIS and the regulation of developmental processes. Endocrine disruptors are compounds that can mimic HORMONES, or enhance or block the binding of hormones to their receptors, or otherwise lead to activating or inhibiting the endocrine signaling pathways and hormone metabolism.
endocrine disrupting compound definition: exogenous agent that mimics endogenous hormones, or interferes with the production, release, transport, metabolism, binding, action or elimination of natural hormones in the body responsible for the maintenance of homeostasis and the regulation of developmental processes.
Intolerance definition: An inability to absorb or metabolize certain substances in the normal way.
