Chlorothalonil (2,4,5,6-tetrachloroisophthalonitrile) is an organic compound mainly used as a broad spectrum, nonsystemic fungicide, with other uses as a wood protectant, pesticide, acaricide, and to control mold, mildew, bacteria, algae. [2]
Chloranil is a quinone with the molecular formula C 6 Cl 4 O 2. Also known as tetrachloro-1,4-benzoquinone, it is a yellow solid. Also known as tetrachloro-1,4-benzoquinone, it is a yellow solid. Like the parent benzoquinone, chloranil is a planar molecule [ 2 ] that functions as a mild oxidant.
In 40 CFR 156.62, the EPA established four Toxicity Categories for acute hazards of pesticide products, with "Category I" being the highest toxicity category (toxicity class). Most human hazard, precautionary statements, and human personal protective equipment statements are based upon the Toxicity Category of the pesticide product as sold or ...
Toxicity class refers to a classification system for pesticides that has been created by a national or international government-related or -sponsored organization. It addresses the acute toxicity of agents such as soil fumigants , fungicides , herbicides , insecticides , miticides , molluscicides , nematicides , or rodenticides .
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
To the peasant farmers, the campesinos, the cause of the contamination is evident. The hills contain flecks of gold ore, one of the rarest minerals on Earth. And for 22 years, the American company Newmont Mining Corp., with financing from the business-lending arm of the World Bank, has blasted apart hills and used toxic chemicals to get it out.
Toxic flame retardants can get into black plastic kitchenware and other items because the black plastic used to make them sometimes includes recycled electronic products that contain flame retardants.
The mechanism of action is the insecticide binding at the GABA A site in the GABA-gated chloride channel (IRAC group 2A), which inhibits chloride flow into the nerve. [12]: 257 Other examples include dicofol, mirex, kepone, and pentachlorophenol. These can be either hydrophilic or hydrophobic, depending on their molecular structure. [13]
