“…Cypermethrin as a hydrophobic organic compound which adsorbs to sediments and according to the literature it is toxic to aquatic organisms (Tomlin 2010). On the other hand, once they have been adsorbed to sediment, they can leach and cause long-term contamination of watercourses (Turgut et al 2010). Major reported sources of cypermethrin in surface water include agricultural and urban runoff from rainstorms, spray drift, urban landscape irrigation and release of agricultural tailwaters (Wang et al 2009).…”

Determination of selected pesticides in water samples adjacent to agricultural fields and removal of organophosphorus insecticide chlorpyrifos using soil bacterial isolates

The use of pesticide for crops leads to serious environmental pollution, therefore, it is essential to monitor and develop approaches to remove pesticide from contaminated environment. In this study, water samples were collected to monitor pesticide residues, and degradation of chlorpyrifos was also performed using soil bacteria. Identification of pesticide residues and determination of their levels were performed by high-performance liquid chromatography with photodiode array detector. Among 12 samples, 10 samples were found contaminated with pesticides. Chlorpyrifos was detected in four tested samples and concentrations ranged from 3.27 to 9.31 lg/l whereas fenitrothion ranging from (Below Detection Limit, \0.1 lg/ l) to 33.41 lg/l in the tested samples. Parathion was found in two tested samples at the concentration of 0.73 and 6.23 lg/l. None of the tested samples was found contaminated with Methoxychlor, DDT and Ethion. Three soil bacterial isolates, Pseudomonas peli BG1, Burkholderia caryophylli BG4 and Brevundimonas diminuta PD6 degraded chlorpyrifos completely in 8, 10 and 10 days, respectively, when 20 mg/l chlorpyrifos was supplied as sole source of carbon. Whereas, BG1, BG4 and PD6 took 14, 16 and 16 days, respectively, for complete removal of 50 mg/l chlorpyrifos. Chlorpyrifos degradation rates were found maximum by all three isolates at 2nd day of incubation for both tested concentrations. The results of the present study suggest the need for regular monitoring of pesticide residues in water, to protect the aquatic environment. Chlorpyrifos degrading bacterial isolates can be used to clean up environmental samples contaminated with the organophosphate pesticides.

“…European Union REACH regulation Annex XVII places a limitation of using eight PAHs in certain products and concentration limits as well as restriction by US EPA in the use of 18 PAHs in consumer goods. Following signature and ratification of Stockholm Convention by Turkey in 2005, Turkish authorities and policy makers have encouraged researchers to conduct studies on the occurrence and fate of environmentally hazardous semi-volatile organic pollutants including persistent organic pollutants (POPs) and PAHs (Turgut et al 2010a;Turgut et al 2012;Turgut et al 2010b;Falay et al 2013). Combustion of materials containing carbon and hydrogen in domestic heating, industrial processes, power plants, motor vehicle, and waste incineration exhaust generate huge amount of PAHs.…”

Polycyclic aromatic hydrocarbons (PAHs) were analyzed at different altitudes of Taurus Mountains in semipermeable membrane devices (SPMD) and in half-, one-and-a-half-, and two-and-a-half-year-old pine needles. SPMDs were deployed for three different exposure periods: March to September (Summer), September to March (Winter), and March to March (whole year) at eight sites where needle samples were collected. The values of PAHs in needles were between 4.4 to 6066 pg g/fw in half-year-old, 7.2 to 111,115 pg g/fw in 1.5-year-old, and 9.7 to 85,335 pg g/fw in 2.5-year-old needles. Mass of PAHs collected by SPMDs varied from

“…Comparable γ-HCH concentrations have been reported in the Kucuk Menderes River in Turkey (Turgut, 2003) and the Yamuna (Kumar et al, 2012) and Brahmaputra (Chakraborty et al, 2016) in India. Banned organochlorine pesticide residues have also been reported in surface water from a national park in Turkey (Turgut et al, 2010). The elevated concentrations in the Syr Darya suggests that despite the ban on legacy POPs some of these organochlorine pesticides may continue to occur in the riverine environment of Kazakhstan.…”

Legacy and current pesticide residues in Syr Darya, Kazakhstan: Contamination status, seasonal variation and preliminary ecological risk assessment

The Syr Darya is one of two major rivers in Central Asia supplying critical fresh water to the Aral Sea. In spite of the river's importance and agriculturally-intensive history, few studies have provided a modern evaluation of and the occurrence of pesticide residues potential effects to aquatic life. The primary goal of this investigation was to determine seasonal variations in ambient concentrations of modern and legacy pesticides in bottom sediment and water of the Syr Darya in Kazakhstan (KZ) downstream from an agriculturally-intensive watershed in Uzbekistan. Grab samples and passive samplers were used at five remote sampling stations during June 2015 to provide a baseline for ecotoxicological evaluation. Results were compared with samples collected during and after the agricultural growing season. Polar organic chemical integrative samplers (POCIS) were used in June and calibrated for time-weighted average concentrations of current use pesticides. Among legacy chlorinated pesticides measured in grab samples from the river, lindane (γ-HCH) was detected most frequently with the highest concentrations occurring during June. For all the sampling events, residues of lindane (γ-HCH) ranged from 0.014 to 0.24 μg/L detected in water samples, are among the highest concentrations reported for rivers globally. Concentrations of γ-HCH, p,p'-DDE and dieldrin were highest in October when dieldrin concentrations approached 0.4 μg/L. Sources of legacy pesticides may be either illicit upstream use or evidence of previous atmospheric contamination of glacial meltwater. Chronic exposure to these residues may lead to ecological risk to lower order organisms in both the sediment and water column.
