Organochlorine pesticides
-
In this work, a GC-MS/MS-based analytical method using accelerated solvent extraction combined with multi-layer silica gel column for sample preparation was developed to simultaneously determine 20 organochlorine pesticides (OCPs), 28 polychlorinated biphenyls (PCBs) and 8 polybrominated diphenyl ethers (PBDEs) in fish tissue.

Ebook "Bioremediation in Latin America: Current research and perspectives" compiles an update information about the state of bioremediation in emerging Latin American countries. Some of the studied regions are sites that suffered decades of pollution by agrochemicals, heavy metals and industrial waste due to the lack of control by government regulations. Such is the case of Northern Argentina, where were illegally deposited over 30 tn of obsolete organochlorine pesticides in 1994.

DDT (Dichloro-diphenyl-trichloroethane) and chlordane are the organochlorine pesticides (OCPs) dangerous to human health and easily accumulate in biological tissues, used to control insects in crops, livestock and house protection. This study aimed to evaluate the toxicity of DDT, cis (alpha-chlordane), and trans (gamma-chlordane) on the growth of two crustaceans species Daphnia magna (D. magna) and Moina macrocopa (M. macrocopa) after 24 h and 48 h.

This work illustrates the challenges of extrapolating laboratory results to onsite determinations and suggests that more robust methods are needed in calculating ecological risk assessments for indigenous animals, particularly for legacy sites with substantial spatial variability.

The use of organochlorine pesticides (OCPs) has decreased considerably worldwide; they have been banned in most countries due to adverse impacts on wildlife. The purpose of the study was to investigate OCP residue levels in wild birds from Aegean, Marmara, Mediterranean, and Central Anatolia geographical regions of Turkey. Feather samples (n = 80) of four bird species in four regions were collected from anthropogenically dead birds such as roadkill and wind turbine collision. Feather samples were analysed using GC/MS and scanned for 23 pesticide congeners.

The investigation aimed to study the contamination of locally marketed spices in Tripoli (caraway, cumin, cinnamon, mixed spices, black pepper, and red pepper) during (2014). Sixty samples of various kinds of spices were extracted and determined for residues of organophosphorus (malathion, methylparathion, parathion, carbo-phenothiate and ethion) and organochlorine pesticides (aldrin, BHC, heptachlore, lindane, DDT, endrin, heptachlor epoxide and dieldrin).

In this study, the pesticide residues of organochlorine, organophosphate, and synthetic pyrethroid were monitored in market fish samples of different regions of Punjab. The pesticide residues were estimated by multiple residue analytical technique using gas chromatography equipped with GC-ECD and GC-FTD. The confirmation of residues was done on gas chromatography mass spectrometry. The results showed the presence of hexachlorocyclohexane (HCH) as predominant contaminant in market fish samples.

In order to increase agricultural production different type of pesticides viz., organochlorines, carbamates etc. are used on large scale to kill unwanted insects, pests, plants etc.; as mode of action of most of them is not specific, they often harm or kill organisms other than pests, including humans. Residues of most common pesticides could affect the ultimate consumers (animal and human) especially when pesticide treated fruit/vegetables are consumed raw. Proper processing technique in daily use of vegetables and fruits i.e. washing, peeling boiling, cooking, frying, sun drying etc.

This study was conducted from May to November 2017 to evaluate the accumulation of organochlorine pesticide chemicals (OCPs) in fish, Bostrychus sinensis, growing at the Soai Rap estuary, Ho Chi Minh City, Vietnam. The pesticide chemicals in the tissues of fish and the sediments of the estuary were analyzed using a gas chromatography method and Varian GC-450 (ECD) instrument. The results showed that in all tissue samples of fish, the content of DDTs was the highest (9.524 ng/g), followed by aldrin (1.209 ng/g); HCHs (1.972 ng/g); dieldrin (1.743 ng/g) and endosunfans (1.

This paper presents the survey data of residues of OCPs in some organisms living in tidal flats in the northern part of Vietnam during the year 2013–2014. The results show that the total residue of OCPs in shellfish ranged from 5.57 µg/kg to 116.04 µg/kg dry weight.

Worldwide, there is much research on assessing the accumulation of OCs in the environment, as well as the analysis and evaluation of their presence in breast milk, with the aim of defining the origin of morbidity and fatality in humans by these chemicals. However, there are few studies on this problem in Vietnam. This study was conducted in some suburban communes of Hue city. Its objective is to assess the content of OCs in breast milk.

The residue of pesticides in water mainly depended on the crops season and have highest value in the beginning of growing period. The concentration of pesticides residues decreased from rice- field to canal and river. There were many forbidden pesticide such as HCH, Endosulfan, Heptachlor, Dieldrin etc. have been found with high frequency in water. It causes a big risk for human heath and aquatic biota.

It is evident that insecticides have been used to boost food production to a considerable extent and to control vectors of disease. However, these advantages that are of great economic benefits sometimes come with disadvantages when subjected to critical environmental and human health considerations. Many insecticides are newly synthesized whose health and environmental implications are unknown.
