“…Heptachlor epoxide was present in the lowest concentration. Concentrations of dieldrin in this study were remarkably lower in comparison to other surface waters (Ayas et al 1997;Turgut 2003;Golfinopoulos et al 2003). Aldrin and dieldrin are closely related organochlorines.…”

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

“…However, very little information exists on their environmental levels in different compartments (surface waters, sediment, and biota) in Turkey (Turgut, 2003;Ayas et al, 1997) and there are no previous studies on atmospheric OCP concentrations.…”

“…The extracted solution was filtered with sodium sulphate and evaporated under vacuum rotary evaporation at 37C until about 2 mL and driedoff using a stream of nitrogen gas. The final volume of the solution was adjusted to 1 mL with ethyl acetate prior to gas chromatography with electron capture detection [5,12,13].…”

This study was conducted in four intensive agricultural areas of the Fang district, Chiang Mai, northern Thailand. The objective of this study was to determine synthetic pyrethroid residues in vegetable, fruit, sediment, and surface water samples. Fruit and vegetables were purchased from local markets in the study areas. The vegetables in this study included cabbage, kale, water spinach, cauliflower, Chinese cabbage, Chinese mustard, yard long bean, cucumber, and sugar pea, while the fresh fruit included tangerine, guava, apple, dragon fruit, mango, sand pear, rose apple, lychee and grape. Sediment and surface water samples were collected from main streams of the four studied areas. The pyrethroid residues in vegetables, fruit, and sediment samples were extracted with dichloromethane in an ultrasonic bath and cleaned up on a graphite carbon cartridge. Liquid -liquid extraction technique was used to prepare pyrethroid compounds from surface water samples. The extracted samples were determined by using gas chromatography -electron capture detection (GC-ECD). Six synthetic pyrethriod pesticides in this study consist of lambda cyhalothrin, permethrin, cyfluthrin, cypermethrin, fenvalerate, and deltamethrin. Cypermethrin was found to be the highest detection percentage in surface water, vegetables, and fruit samples at 33.3, 75.8 and 95.3%, respectively. Meanwhile, permethrin was the highest detection percentage in sediment samples at 66%. However, lambda cyhalothrin was detected in sediment and surface water samples with the highest levels at 0.38 and 1.61 mg/kg, respectively. Deltamethrin was detected in vegetable samples with the highest level at 9.97 mg/kg and cypermethrin was detected in fruit samples with the highest level at 11.83 mg/kg. Furthermore, this study is an application of the developed method providing a high sensitivity with the limit of detection (LoD) of permethrin at 0.11 mg/kg, cyfluthrin at 0.11 mg/kg, fenvalerate at 0.22 mg/kg, lambda cyhalothrin at 0.26 mg/kg, cypermethrin at 0.51 mg/kg and deltamethrin at 0.65 mg/kg.
