The level of organochlorine pesticides in 229 samples of Spanish meat and meat products of different species (lamb, pork, beef and poultry) was investigated. Chlorinated residues were quantitated by gas-liquid chromatography with electron capture detector using packed and capillary columns. Hexachlorobenzene (HCB) and hexachlorocyclohexane (HCH) were detected in all samples. In general, lamb appeared to be more heavily contaminated by HCB and HCH, which reached maximums of 178 ppb (μg/kg on a fat basis) and 505 ppb, respectively. The level of HCB averaged 49 ppb in lamb; varied between 8–18 ppb in pork and beef products; and amounted to 26 ppb in fresh poultry sausages. Of the three isomers of HCH determined, the γ-HCH (lindane) was most frequently detected; 100% in lamb and pork (both meat, cured sausage and pork bologna), and 64 to 94% in fresh sausages of poultry and beef. The level of the HCH group averaged 112 ppb in lamb, 85 ppb in poultry, nearly half that much in pork and pork products, and around 20–40 ppb in beef products. Dieldrin was the only chlorocyclodiene detected: 8 to 15% in pork products, and 28% in fresh poultry sausage. The DDTs in lamb showed 83% of detection, especially in the pp' form of DDE and DDT. The overall contamination with DDT and its metabolites was found to be very moderate averaging 25 ppb, with a maximum of 91 ppb. No residues of aldrin, endrin, heptachlor, heptachlor epoxide, chlordane, methoxychlor, endosulfan or trans-nonachlor were detected.

The Individual

Abstract A method is described for the determination of organochlorine pesticide residues in human gallstones. The difficulty caused by the presence of large amounts of cholesterol in the stones is overcome by an acetylation step in the "clean-up" procedure, and the method finishes with identification and determination of the individual pesticides by gas-liquid chromatography. Results are given for 28 samples submitted by 2 hospitals, showing small amounts of dieldrin, p,p'-dichlorodiphenylethane (pp'-DDE), and benzene hexachloride (BHC) isomers to be commonly present in small amounts in gallstones. Some explanation for the presence of these residues in the stones is given. A case of suspected poisoning by these compounds showed an unusually large amount of dieldrin in the patient's stones.

Gas Chromatographic Method

This paper collected 18 soil samples in the Chin-sha River basin, and analyzed residues of organochlorine pesticides (OCPs) in soil using gas chromatographic method, revealing the organochlorine pesticide residues, the distribution and sources in the river basin. The results show that, the relatively high sampling residues of organochlorine pesticide distribute in the industrial area. The composition and characteristics of organic chlorine pesticide show that the organochlorine pesticide residues in soil mainly come from the historical use. Compared with the domestic similar research, residual organochlorine pesticides in Chin-sha River basin were lower.

Between December 1982 and October 1983 samples of human body fat were taken during routine necropsies carried out on 187 persons aged over 5 years and four infants aged under 4 months. Comparison of the results of analysis with those from the previous studies in 1976-1977, and earlier, shows a continuing decline in residues of p,p'-dichlorodiphenyltrichloroethone (p,p'-DDT) and dieldrin (HEOD) and a reduction in the amounts of p,p'dichlorodiphenyldichloroethene (p,p'-DDE, a metabolite of p,p'-DDT] and hexachlorobenzene. The concentrations of other compounds were similar to those observed in the previous studies. The results show that the amounts of organochlorine pesticides and polychlorobiphenyl compounds contained in human fat samples from residents in the UK compare favourably with data obtained in other countries.

1 The concentrations of some organochlorine pesticides and polychlorobiphenyl compounds have been determined in 102 samples of human milk collected between January 1979 and September 1980. 2 Comparison of the results with those from a limited study undertaken in 1963-4 shows a decline in residues' levels. 3 The concentrations of organochlorine pesticides and polychlorobiphenyls in human milk samples from residents in Great Britain compare favourably with data obtained in other countries.

Mother’S Milk

A total of 24 samples of mother's milk collected during the first week of lactation from four major cities in India (Karnal, Bangalore, Calcutta and Bombay) were analysed for the estimation of organochlorine pesticides (OCPs). α-HCH, p,p'-DDE, and p,p'-DDT were generally the main contaminants. The average total 1,1,1-trichloro-2,2-bis (p-chlorophenyl) ethane (DDT) levels stand at 0.05, 0.11, 0.19 and 0.22 p.p.m. (whole-milk basis) in the samples from Bangalore, Calcutta, Karnal and Bombay respectively. In the same order total hexachlorocyclohexane (HCH) levels were around 0.01, 0.03, 0.03 and 0.05 p.p.m. Wide variations among OCP levels observed in the present study have no relation with the fat content of the various samples. The samples from Calcutta and Bombay showed significantly high levels of OCPs. The daily intake of total HCH and DDT residues calculated for the suckling infant was significantly higher in the present study when compared with the WHO recommended value.

Organochlorine Pesticide Residues

According to Codex Alimentarius, pesticides are considered as chemicals that prevent, suppress, destroy and repel some pests during manufacture, storage, transport or processing of food, feed and agricultural goods. These chemicals can also be used as plant growth regulator, as defoliant, agent inhibition. The purpose of this study was to evaluate the content of organochlorine pesticides in  home-grown vegetables products. The objectives were the establishment of the working matrices and the organochlorine pesticides determination in the matrices chosen by GS method. Due to the high cost of analysis, the vegetable matrix was consisted in 12 sample- lettuce and spinach samples grown in garden and  roots samples (carrots, parsley, parsnip and celery) from both home-grown production. Organochlorine pesticide residues were extracted from the sample with acetonitrile and petroleum ether, purified by passage through florisil column and eluted with a mixture of ethyl ether and petroleum ether. Concentrated eluate was subjected to gas chromatographic determination.In all examined samples, there were identified organochlorine pesticide residues with high residual, HCH, DDE, DDT, DDD, endosulfan, and heptachlor, some being above the maximum allowed by European legislation

Abstract Florisil solid-phase extraction cartridges were evaluated for cleanup of organochlorine pesticide residues in food extracts. Elution patterns and recoveries were determined for 24 organochlorine pesticides. A range of elution solvents was evaluated. A 2% ethyl ether–petroleum ether eluant optimized overall recoveries while minimizing interferences from coextractants.

Abstract Fifteen laboratories collaboratively determined parathion, o,p′-DDT, p,p′-DDT, and p,p′-DDE in kale, and lindane, dieldrin, heptachlor epoxide, and p,p′-DDE in eggs, using electron capture gas-liquid chromatography (potassium chloride thermionic detector for parathion). Pesticide levels ranged from 0.033 ppm heptachlor epoxide to 3.32 ppm p,p′-DDT. Mean recoveries (± standard deviations) were: parathion 91±15%, o,p′-DDT 99±8%, p,p′-DDT 97±8%, lindane 94±4%, dieldrin 106±8%, heptachlor epoxide 106±5%, p,p′-DDE 94±8% in eggs and 101±9% in kale. The methods have been adopted as official first action.
