“…Pollution caused by organochlorine pesticides is widespread all over the world [43]. Although most OCPs were banned between the 1970s and 1990s, they may still remain in the soil due to their persistent physical and chemical properties [44,45]. It has been reported that OCPs are distributed throughout the globe including regions where they were not or have never been used [46].…”

Dicofol is an organochlorine insecticide widely used to prevent pests worldwide. Consequently, serious environmental problems have arisen from the application of dicofol. Bioremediation is an effective solution for dicofol persistence in the environment. In this study, a bacterial strain D-2, identified to genus Microbacterium, capable of degrading dicofol was isolated from dicofol-contaminated agricultural soil. This represents the first dicofol degrading bacterium isolated from this genus. Microbacterium sp. D-2 degraded 50 mg/L dicofol within 24 h at a rate of 85.1%. Dicofol was dechlorinated by D-2 and the further degradation metabolite was indentified as p,p′-dichlorobenzophenone(DCBP). Soils inoculated with Microbacterium sp. D-2 degraded 81.9% of the dicofol, while soils without D-2 only degraded 20.5% of the dicofol present. This finding suggests that strain D-2 has great potential in bioremediation of dicofolcontaminated soils.

“…For quantitative risk assessment Target Hazard Quotient was calculated (THQ) (the ratio of the potential exposure to a substance and the level at which no adverse effects are expected). The hazard ratios were assessed by this Equation THQ=EDI/RFD Where RFD (reference oral dose) (mg/kg-day) for each organochlorine (ORD, 2017).EDI (Estimated daily intake) (mg/kg-day) calculated by this equation (Mahmoud et al, 2016). EDI=(C×W)/Bw Where C (mg/kg) is the concentration of OCP residue in contaminated samples, W represents the daily average consumption of food and Bw represents the body weight.…”

Dietary fat and oil is important for many body processes. The present investigation was carried out to determine the concentrations of organochlorine pesticides in butter, olive and corn oil. A total of 125 samples (75 butter, 25 each of olive oil and corn oil) were collected from El Minia Governorate, Egypt. Levels of these compounds were determined by gas chromatography with electron capture detector (GC-ECD). The results indicated that 30.4%(38/125), 24.8%(31/125), 21.6%(27/125), 21.6%(27/125), 16.8%(21/125), 14.4%(18/125), 14.4%(18/125), 12.8%(16/125), 9.6%(12/125), 8.8%(11/125), 8%(10/125), 1.6%(2/125) and 0.8%(1/125) of the examined samples were contaminated with Heptachlor, Endrin, Aldrin, Dichlorodiphenyldichloroethylene(p,p'-DDE), Dichlorodiphenyldichloroethane(p,p'-DDD), Gamma hexachlorocyclohexane(Gamma HCH), Heptachlor epoxide, Dieldrin, Endosulfan, methoxychlor, Alpha hexachlorocyclohexane(Alpha HCH), Delta hexachlorocyclohexane(Delta HCH) and Gamma Chlordane, respectively. None of the examined samples revealed the presence of Dichlorodiphenyltrichloroethane (p,p'-DDT) and 11 samples contained organochlorine residues above European Union maximum residue limits (EU MRL)..

A new rice−loach co-culture system was introduced into the Honghe Hani Rice Terraces (HHRT), China, to promote sustainable development of this World Heritage region. However, little is known about the survival of loaches in this area and whether they are safe to eat after having been exposed to residual organochlorine pesticides (OCPs). Although some OCPs such as dichlorodiphenyl trichloroethanes (DDTs), hexachlorocyclohexanes (HCHs), aldrin, and dieldrin have been banned in China, they can still be detected in the agricultural environment. In this study, water, sediment, and loaches (water and sediment collected 3 times; loaches only at harvest) in the HHRT were simultaneously sampled throughout the culture season and analyzed for 22 selected OCPs. Results showed that the concentration of total OCPs in the water and sediment uniformly decreased in the following order May > August > October and that samples collected during August and October clustered together in nMDS analysis, differing from those collected in May. Some OCPs, such as heptachlor, heptachlor epoxide, endosulfan I, endosulfan II, DDTs and HCHs were present in abundance. DDTs and HCHs were persistently present in low sediment concentrations at 0.21−1.27 and 0.01−0.95 µg kg −1 , respectively, suggesting that a new origin of these pesticides may exist. Hepta chlor accounted for the majority of OCPs at the beginning of the co-culture season and was calculated to influence the survival of loaches. Residual OCPs were generally not detected in the muscle of loaches (i.e. the edible part of loaches) being sent to market and therefore pose a low risk to humans who eat them. Overall, the results of this study will be useful in the production and consumption of loaches in rice−loach coculture systems, as well as for the promotion of sustainable development of the HHRT.
