“…Looking at the ratio of the mean concentration of p, p'-DDD to its parent compound p, p'-DDT in the sediment samples, the results indicated less recent exposure to new sources of DDT and accumulation was probably through indirect use such as long range transport or historical application (Hong et al, 1999;Zhang et al, 1999;Adeyemi et al, 2011). The results in this study showed higher levels of OCPs compared with what was previously reported by Raposo jr et al (2007) from water bodies in Culturama Brazil and Shukla et al (2006) in Hyderabad city in India; whilst the Okavango delta in Botswana showed similar ranges in some instances as reported by Mmualafe et al (2009). www.ccsenet.org/enrr Environment and Natural Resources Research Vol. 5, No.…”

This study considered the levels of 15 organochlorine pesticide (OCPs) residues (α-BHC, β-BHC, ϒ-BHC, lindane, chlorothalonil, heptachlor, aldrin, heptachlor epoxide, endosulfan I, endosulfan II, endrin, dieldrin, p, p'-DDD, p, p'-DDT and endosulfan sulphate in water, sediments and fish species from Ogbese river in Ekiti State, Southwestern Nigeria. Samples were extracted and cleaned-up on silica gel adsorbent. The OCPs concentrations were determined using Gas chromatograph (GC) equipped with Electron Capture Detector. The OCPs concentration in water and sediments ranged from below detection limit (BDL): BDL -13.6 µg/L and 0.52 -450 µg/kg whilst the mean OCPs in the fish ranged from 2.64 -66.0 µg/kg, respectively. The results indicated that all the analysed fish samples were contaminated with the studied pesticides. Endosulfan I was found to be above EU and FAO/WHO maximum residue limits (MRL) in Clarias gariepinus fish samples. The sediments and fish samples showed evidence of organochlorine pesticides enrichment and bioaccumulation. Chi-square at α = 0.05 showed there were significant differences in the levels of organochlorine pesticide residues in sediments and fish samples except α-BHC.

“…Porém, por falta de informação ou pelo interesse único no lucro, a produção agrícola contribuiu de forma efetiva para a contaminação das águas, tanto em nível superficial quanto subterrâneo. 1 O estado de Mato Grosso do Sul (MS) em 2008 foi o 9º estado em produção agrícola do país e, em função disto, o uso de pesticidas (defensivos agrícolas ou agrotóxicos) foi bastante intensificado. 2 No distrito de Culturama, localizado na cidade de Fátima do Sul, as culturas temporárias (cana-de-açúcar, soja, mandioca, arroz, feijão e tomate) são predominantes e um grande número de inseticidas e acaricidas são aplicados.…”

Recebido em 2/9/10; aceito em 16/2/11; publicado na web em 15/4/11 ANALYSIS OF ORGANOCHLORINE PESTICIDES IN WATER USING HEADSPACE SOLID PHASE MICROEXTRACTION WITH GAS CHROMATOGRAPHY AND MASS SPECTROMETRY. A method based on headspace -solid phase microextraction coupled with gas chromatography -mass spectrometry was validated for the quantitative determination of 18 organochlorine pesticides in water. For the extraction conditioning some parameters as the best type of coating fiber, time and temperature of extraction, pH and ionic strength were evaluated. The method HS-SPME/GC-MS/MS showed linear coefficient above 0.9948. The repeatability of the measurements were lower than 7.6%. Relative recoveries were between 88 and 110%. Limits of detection from 0.5 x 10 -3 to 1.0 mg L -1 were obtained. A total of 31 samples were analyzed and 16 presented from 1 to 5 pesticides.Keywords: organochlorine pesticides; HS-SPME/GC-MS/MS. INTRODUÇÃOO setor agrícola vem se esforçando a cada ano para aumentar a produção de alimentos, tanto para o mercado interno quanto para o externo. Porém, por falta de informação ou pelo interesse único no lucro, a produção agrícola contribuiu de forma efetiva para a contaminação das águas, tanto em nível superficial quanto subterrâneo. No distrito de Culturama, localizado na cidade de Fátima do Sul, as culturas temporárias (cana-de-açúcar, soja, mandioca, arroz, feijão e tomate) são predominantes e um grande número de inseticidas e acaricidas são aplicados.3 O uso de pesticidas adquiridos de forma ilegal de países vizinhos (Paraguai e Uruguai) tem sido reportado pela imprensa brasileira, principalmente em alguns estados da Federação, como Rio Grande do Sul, Paraná e Mato Grosso do Sul, devido à proximidade com estes países. Os pesticidas podem ser adquiridos no Paraguai pagando-se até dez vezes menos o valor praticado no Brasil. 4 Pelo fato destes produtos não passarem por um controle de qualidade, não se sabe exatamente a sua composição química e, consequentemente, a concentração que está sendo aplicada, elevando o risco à saúde humana e ao meio ambiente. O Ministério da Agricultura e a Polícia Federal têm intensificado ações para detectar, penalizar e coibir tais práticas.Os organoclorados são compostos sintéticos de cadeia cíclica com baixa massa molecular e pouco solúveis em água e solúveis em solventes orgânicos, o que os torna mais tóxicos e de apreciável absorção cutânea.5 Além da via dérmica, são também absorvidos por via digestiva e respiratória. Devido à grande lipossubilidade e à lenta metabolização, esses compostos se acumulam na cadeia alimentar e no tecido adiposo. A eliminação se faz pela urina e também pelo leite materno.6 Por essas características, os pesticidas organoclorados têm sido progressivamente restringidos ou mesmo proibidos. As primeiras restrições feitas ao seu uso foram ainda na década de 60. O hexaclorobenzeno (HCB) teve sua comercialização proibida em 1983 e neste ano a ANVISA (Agência Nacional de Vigilância Sanitária) divulgou que o endosulfan, por ser considerado ...

“…Analytical procedure Solid phase extraction disks followed by gas chromatographic techniques were used for the detection of organochlorine pesticides (APHA et al 1992;Vidal et al 1993;Shukla et al 2006). The 1 l samples were prefiltered by vacuum filtration through 0.45 μm filter paper to remove particulates before pesticide extraction.…”

The levels of 16 organochlorine pesticides (OCPs) in surface water in Mid-Black Sea Region in Turkey were investigated to evaluate their potential pollution and risks. The analysis of OCPs extracted by C-18 solid phase extract was performed using Fisions Mega II Series gas chromatograph coupled by electron capture detector. Surface water samples have been collected seasonally from ten rivers for a period of 1 year. The most commonly encountered OCPs in surface water were the isomers of hexachlorocyclohexane, dieldrin, p,p-DDD, and heptachlor epoxide. In some cases the concentrations detected were higher than the qualitative target levels set by the European Union, especially for δ-hexachlorocyclohexane. The concentration levels found are lower than the EU maximum acceptable concentration of 0.10 μg/l for all compounds examined, except for δ-HCH in two samples (0.2505 μg l −1 in the S-5 and 0.2046 μg l −1 in the S-10). The occurrence of these compounds
