Pesticide use raises a number of environmental concerns. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including non-target species, air, water and soil. Pesticide drift occurs when pesticides suspended in the air as particles are carried by wind to other areas, potentially contaminating them. Organochlorine insecticides are a group of highly persistent pesticides, derivatives of aliphatic or aromatic hydrocarbons, very resistant to biodegradation. The basic mechanisms of the majority insecticides of this group are expressed as stimulation of central nervous system that occurs due to non-GABAergic effect, and additionally many of them inhibit specific ATPases in : Teuta Murati, Branimir Šimić, Jasna Kniewald, Jelka Pleadin, Ivana Kmetič.

Pesticides are an integral component of US agriculture and account for about % of total farm production costs (Aspelin and Grube, ). Pesticide use in the United States averaged over billion pounds of active ingredient in , and was associated with expenditures exceeding $ billion; this use involved o products and more than active ingredients.   A number of chemicals, including several organochlorine pesticides, have been identified as persistent organic pollutants (POPs). Here, the properties of chlorpyrifos (CPY; CAS No. ) and its active metabolite, chlorpyrifos oxon (CPYO; CAS No. ), are assessed relative to criteria for classification of compounds as persistent, bioaccumulative, and toxic substances (PBTs).Cited by:

Organochlorine Pesticides. Organochlorine pesticides (OCPs) are an organic compound with highly toxic, refractory and easily residual characteristics, They were used in large quantities as pesticides in China's agricultural production process, resulting in large amounts.

An organochloride, organochlorine compound, chlorocarbon, or chlorinated hydrocarbon is an organic compound containing at least one covalently bonded atom of chlorine that has an effect on the chemical behavior of the chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) provides common examples.

The wide structural variety and divergent chemical. Production and use. DDT has been formulated in multiple forms, including solutions in xylene or petroleum distillates, emulsifiable concentrates, water-wettable powders, granules, aerosols, smoke candles and charges for vaporizers and lotions.

From toDDT was extensively used in agriculture – more t tonnes each year worldwide – and it has been estimated that a total Chemical formula: C₁₄H₉Cl₅.

The continuing use of organochlorine pesticides and PCBs in India is of concern (Kannan et al., ; Kannan et al., a; Kannan et al., b; Tanabe et al., ). The Ganges river basin is densely populated and heavily polluted by fertilizers, pesticides, and industrial and domestic effluents (Mohan, ).

In addition to fish, other Cited by: Organochlorine pesticides (OCPs) show multiple effects on the major physiological systems of the body including nervous, circulatory, and reproductive system and, also at some critical growth.

Organochlorine Insecticides. This group of insecticides was used widely in agricultural production earlier than other insecticides. In particular, the invention of DDT is considered the beginning of modern pesticide use.

These insecticides have road-spectrum activity and are very persistent. There are two kinds of organochlorine insecticides.

Pesticide Explained. Pesticides are substances that are meant to control pests, including weeds. The term pesticide includes all of the following: herbicide, insecticides (which may include insect growth regulators, termiticides, etc.) nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, antimicrobial, and fungicide.

Bio of Colin Walker, author of Principles of Ecotoxicology, 4ed, Colin H. Walker worked at Monk`s Wood Experimental Station { NERC ] as a Scientific Officer, later Senior Scientific Officer, in the `Toxic Chemicals and Wildlife Section` headed by Dr Norman Moore, he studied the side effects of organochlorine insecticides on birds and insects, and the fate of residues of these.

Pesticides are also found in majority of U.S. households with 88 million out of the million households indicating that they use some form of pesticide in [27] [28] As ofthere were more than 1, active ingredients registered as pesticides, [16] which yield o pesticide products that are marketed in the United States.

@article{osti_, title = {Organochlorine pesticides and PCBs in human adipose tissues in Poland}, author = {Ludwicki, J K and Goralczyk, K}, abstractNote = {Most of the persistent organochlorine (OC) pesticides, excluding lindane, were banned in Poland in / The first restrictions concerning the use and marketing of lindane (gamma-HCH) became effective in and were gradually.

Their use peaked in the s when most widely used organochlorine insecticides where phased out or banned. Until as recently asOPs constituted ∼70% of all insecticide used in the U.S., but that value has been halved in the following years (eg, 33% in Cited by: Other Organochlorine Insecticides • Toxaphene, a mixture of hundreds of similar substances (partially chlorinated camphene- pine tree product) was widely used as insecticide during in the US • Toxaphene is extremely toxic to fish • Restrictions were placed in and a total ban in Spread of Toxaphene in Northern America.

Silent Spring is an environmental science book by Rachel Carson. The book was published on Septemdocumenting the adverse environmental effects caused by the indiscriminate use of accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims : Rachel Carson.

The report focusses on the three most widely-used neonicotinoids, but others such as thiacloprid and acetamiprid are not subject to the moratorium or recent review. Some researchers say other newer insecticides may prove harmful to bees and other non-target insects because regulatory procedures have.

However, a study in Thailand found the cost per malaria case prevented of DDT spraying ($ US) to be 21% greater than the cost per case prevented of lambda-cyhalothrin-treated nets ($ US), at very least casting some doubt on the unexamined assumption that DDT was the most cost-effective measure to use in all cases.

Pesticides are substances that are meant to control pests, including weeds. The term pesticide includes all of the following: herbicide, insecticides (which may include insect growth regulators, termiticides, etc.) nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, antimicrobial, fungicide, disinfectant (antimicrobial), and sanitizer.

DDT DDT (dichloro-diphenyl-trichloro-ethane) is an insecticide that was first used worldwide in to increase agricultural production and to reduce disease vectors (carriers).

Although formulated inDDT's insecticidal properties were not discovered until. substances can be listed, and most of them are shown in Table 1.

Of these, 46% are insecticides, 21% herbicides and 31% fungicides; some of them were withdrawn from general use many years ago but are still found in the environment (ex. DDT and atrazine in several countries).Cited by: The word pesticide is a catch-all term for chemicals that kill or control anything that humans have deemed to be a pest.

A danger inherent to the use of synthetic poisons is that once the chemicals are released into the environment, they may harm unintended victims and have unanticipated effects.Watermelon (Citrulus lanatus) samples were freshly harvested from the Mashangwari, Katakamand Krigasawaagricultural locations in Gashua, Bade Local Government Area, Yobe State Nigeria.

The watermelon samples were divided into peel, pulp, seed, leaf, root and stem for the determination of some organochlorine pesticide residues (o, p-DDE, p,p’-DDD, o,p’-DDD, p,p’-DDT, dieldrin and aldrin).
