Oxidants - Chemical species that readily accept electrons. The electron accepting species is reduced in a chemical reaction. [Environmental Science and Technology; v28; 492; 1994.] [Chemical and Engineering News; v69; 30-43; 1991.] ...
Oxidant: A collective term for some of the primary constituents of photochemical smog.
oxidant A substance that contributes electrons during an oxidation-reduction usually containing oxygen that reacts chemically to produce a new substance, i.e., the primary ingredient of photochemical smog.
Oxidant - A substance containing oxygen that reacts chemically in air to produce a new substance; the primary ingredient of photochemical smog.

Paraquat - A standard herbicide used to kill various types of crops, including marijuana.
Oxidant: A substance that brings about oxidation in other substances. Oxidizing agents (oxidants) contain atoms that have suffered electron loss. In oxidizing other substances, these atoms gain electrons.
chemical oxidant and therefore does not necessarily
correlate with biochemical oxygen demand.

Photochemical Oxidants- Air pollutants formed by the action of sunlight on oxides of nitrogen and hydrocarbons.
Photochemical Smog- Air pollution caused by chemical reactions of various pollutants emitted from different sources.
The measure is a laboratory test based on a chemical oxidant and therefore does not necessarily correlate with biochemical oxygen demand.

smog Air pollution associated with oxidants. smoke Particles suspended in air after incomplete combustion of materials. soil carbon A major component of the terrestrial biosphere pool in the carbon cycle.
It can be used to affect the body's antioxidant-prooxidant balance, since the body usually reacts to its presence by producing antioxidant enzymes. Many hospitals in the U.S.
The process of burning fuel and oxidants to produce heat and/or work. Combustion is the main energy release mechanism in the Earth. Fuel can come in the form of gas, liquid or solid ignited by a heat source.
Photochemical smog consists of oxidants caused by the reaction of sunlight on hydrocarbons and nitrogen oxides from vehicle and industrial emissions. The photochemical smog causes cause eye irritation, headaches, coughs and damage lung tissues.
Disinfectant: Any oxidant, including but not limited to chlorine, chlorine dioxide, chloramines, and ozone, ...
Advanced chemical oxidation processes use (chemical) oxidants to reduce COD/BOD levels, and to remove both organic and oxidisable inorganic components.
Any oxidant, including but not limited to chlorine, chlorine dioxide, chloramines, and ozone, that is added to water in any part of the treatment or distribution process and is intended to kill or inactivate pathogenic microorganisms.
superoxide dismutase
Enzymatic antioxidant that removes the potentially toxic superoxide ion (O2- ) by disproportionating it to O2 and hydrogen peroxide (H2O2).
super-threshold dose
See toxic dose ...
The electric potential required to transfer electrons from one compound or element (the oxidant) to another compound (the reductant); used as a qualitative measure of the state of oxidation in water treatment systems.

In the troposphere (the layer extending up 7 to 10 miles from the earth's surface), ozone is a chemical oxidant and major component of photochemical smog.
Air pollution typically associated with oxidants. (See> photochemical smog.)
Smoke
Particles suspended in air after incomplete combustion.
Ozone (O3): A very reactive oxidant containing three atoms of oxygen.
