Atrazine may be catabolized as a carbon and nitrogen source in reducing environments, and some aerobic atrazine degraders have been shown to use the compound for growth under anoxia in the presence of nitrate as an electron acceptor, [35] a process referred to as a denitrification. When atrazine is used as a nitrogen source for bacterial growth ...
Restricted use pesticides (RUP) ... Atrazine is the most widely used restricted-use herbicide, however there are over 700 RUPs as of 2017.
The U.S. EPA said in the 2003 Interim Reregistration Eligibility Decision, "The total or national economic impact resulting from the loss of atrazine to control grass and broadleaf weeds in corn, sorghum and sugarcane would be in excess of $2 billion per year if atrazine were unavailable to growers." In the same report, it added the "yield loss ...
The list of restricted use pesticides is maintained by the US EPA. [89] Additionally, specific environmental pollutants are identified in public law, which extends to all hazardous substances even if the item is not identified as a restricted use pesticide by the EPA.
AtzA is an atrazine-dechlorinating enzyme with fairly restricted substrate specificity and plays a main role in the hydrolysis of atrazine to hydroxyatrazine in soils and groundwater. [3] Atrazine Hydroxyatrazine is a hydrolase (an enzyme that catalyzes the hydrolysis of a chemical bond ), which acts on halide bonds in C-halide compounds.
The word pesticide derives from the Latin pestis (plague) and caedere (kill). [5]The Food and Agriculture Organization (FAO) has defined pesticide as: . any substance or mixture of substances intended for preventing, destroying, or controlling any pest, including vectors of human or animal disease, unwanted species of plants or animals, causing harm during or otherwise interfering with the ...

Pesticide degradation is the process by which a pesticide is transformed into a benign substance that is environmentally compatible with the site to which it was applied. . Globally, an estimated 1 to 2.5 million tons of active pesticide ingredients are used each year, mainly in agricult
