What type of pesticide is organophosphate?

Organophosphates are the most widely used insecticides today. They are used in agriculture, the home, gardens, and veterinary practice. Organophosphate insecticides (such as diazinon) are one type of pesticide that works by damaging an enzyme in the body called acetylcholinesterase.

How many organophosphate pesticides are there?

Organophosphates (OPs) are a class of insecticides, several of which are highly toxic. Until the 21st century, they were among the most widely used insecticides available. Thirty-six of them are presently registered for use in the United States, and all can potentially cause acute and subacute toxicity.

What are the types of organophosphorus compounds?

Organophosphorus compounds (OPs) are a diverse group of chemicals, including insecticides (malathion, parathion, diazinon, fenthion, dichlorvos, chlorpyrifos, and others) and nerve gases (soman, sarin, tabun, and VX).

What is organophosphorus pesticide?

Organophosphorus insecticides are chemicals used to kill many types of insects. These chemicals account for a large share of all insecticides used in the United States, including those used on food crops. Most home uses of organophosphorus insecticides have been phased out in the United States.

What is difference between organophosphorus and organophosphate?

The organophosphorus insecticides are esters of phosphoric acid (or its sulfur analogues) and are therefore often referred to as organophosphates to distinguish them from compounds with a C–P bond. There are several groups of chemically related organophosphates.

What are the properties of organophosphates?

Effective organophosphates have the following structural features: A terminal oxygen connected to phosphorus by a double bond, i.e. a phosphoryl group. Two lipophilic groups bonded to the phosphorus. A leaving group bonded to the phosphorus, often a halide.

Is organophosphate a rodenticide?

An organophosphate rodenticide known as TresPasitos, made with the chemical aldicarb and sold illegally in the United States, has been used primarily by Hispanic individuals. People who ingest this toxin may present with symptoms of acetylcholinesterase inhibition.

Is DDT an organophosphate?

Dichlorodiphenyltrichloroethane (DDT) is a representative organochlorine insecticide and a known endocrine disruptor. Malathion is an organophosphate insecticide and a next-generation pesticide.

Is roundup an organophosphate?

Glyphosate (1) is a non-selective, systematic herbicide. This organophosphate compound is the active ingredient in the weedkiller Roundup.

Is DDT an organophosphate?

Dichlorodiphenyltrichloroethane (DDT) is a representative organochlorine insecticide and a known endocrine disruptor. Malathion is an organophosphate insecticide and a next-generation pesticide.

Are organophosphates banned?

The human and animal toxicity of OPPs make them a societal health and environmental concern; the EPA banned most residential uses of organophosphates in 2001, but their agricultural use, as pesticides on fruits and vegetables, is still permitted, as is their use in mosquito abatement in public spaces such as parks.

Is malathion an organophosphate?

Malathion is a man-made organophosphate insecticide that is commonly used to control mosquitoes and a variety of insects that attack fruits, vegetables, landscaping plants, and shrubs.

Are pyrethroids organophosphates?

Pyrethrins are natural botanical insecticides derived from extracts of the flowers of Chrysanthemum genus, primarily Chrysanthemum cinerariaefolium and coccineum,1 while pyrethroids are synthetic derivatives of pyrethrins. In contrast to organophosphate insecticide, pyrethroids are less toxic to human.

Is organophosphate a rodenticide?

An organophosphate rodenticide known as TresPasitos, made with the chemical aldicarb and sold illegally in the United States, has been used primarily by Hispanic individuals. People who ingest this toxin may present with symptoms of acetylcholinesterase inhibition.

Is Arsenic an organophosphate?

Arsenic is a common global ground water contaminant while dichlorvos is one of the most commonly and widely employed organophosphate based insecticide used in agriculture, horticulture etc. There is thus a real situation where a human may get exposed to these toxicants while working in a field.

What are examples of pyrethroids?

Pyrethroid pesticides are used in agriculture, mosquito control, lawn and garden care, and in veterinary care. Some representative pyrethroids are permethrin, resmethrin, fenvalerate, cyfluthrin, sumethrin and barthrin.

Is DDT a pyrethroid?

In the 1960s, equipped with, at the time, new voltage-clamp techniques, Professor Narahashi and associates provided the initial evidence that DDT and allethrin (the first commercial pyrethroid insecticide) caused prolonged flow of sodium currents in lobster and squid giant axons.
