“…However, these results are different from those found by Kuranchie-Mensah et al (2012), Yuan et al (2013), Wu et al (2013), Bettinetti et al (2016), andHijosa-Valsero et al (2016), in which DDE and DDD concentrations were higher when compared to DDT concentrations. DDE is a metabolite of DDT and a high proportion of this compound denotes a past use of DDT (Barakat et al, 2013).…”

“…Furthermore, the few already performed have only assessed large lakes, where agricultural activity is predominant in the surroundings. Accordingly, we can mention the studies of Zhao et al (2010), Zhao et al (2010), Kuranchie-Mensah et al (2012), Wu et al (2013), Yuan et al (2013), Li et al (2015), Bettinetti et al (2016), and Hijosa-Valsero et al (2016) in freshwater sediments, and those of Barakat et al (2012b), Barakat et al (2012a), Barakat et al (2013), Kafilzadeh (2015), and Pinto et al (2016) in saline water environments.…”

ABSTRACT:The knowledge of pesticide residual concentrations in the environment is important to understand the threats to the environment and human health, especially when natural resources are used for human consumption. In this context, this study aimed to assess the potential ecological risk and respective sources of sediment contamination by organochlorine and organophosphorus pesticides. The study site was an urban lake located in Cascavel city, western Paraná state, Brazil, where the history of land use and occupation in the urban environment is typically agricultural. Surface sediment samples were collected every three months from April 2010 to June 2013 at five different collection points, totaling 65 samples. Analyses showed that contamination by organochlorine pesticides is related to agricultural activities in the past, with a low ecological risk to benthic organisms. Conversely, organophosphorus pesticides presented a recent and continuous contamination from urban activities, with a risk coefficient, especially for disulfoton, indicating a significant potential adverse effect on organisms. However, in general, the obtained results did not indicate an immediate risk to public health.

“…Proportions of DDT and its metabolites vary in the order of DDT [ DDD [ DDE in most cases. DDD is the anaerobic degradation product of DDT, so the degradation of DDT to DDD is expected to increase with depth of water columns and oxygen depletion (Yuan et al 2013). DDE is a less toxic product of DDT under aerobic conditions and could be an intermediate product further converted into DDD (Lugo-Ibarra et al 2011).…”

“…The tropical agroecosystem, characterized by high temperature and heavy rainfall, facilitates the rapid removal of these residues through air and water and ultimately contributes to global contamination including soil, sediment, wildlife, foodstuffs, edible fish and even human breast milk. The use of large amounts of OCPs in China produced the high concentrations of DDTs and HCHs in seawater and coastal sediments, river-estuarine systems or reservoir water, sediment, soil and plants (Yuan et al 2013).…”

Many studies have investigated the contamination level, spatial distribution, sources, chiral signals, and potential ecological and public health risks of dichlorodiphenyltrichloroethanes, its metabolites and the isomers of hexachlorocyclohexane in the environment. This study presents a critical review to provide updated knowledge about the fate, persistence, long-range transport and toxicity effects of dichlorodiphenyltrichloroethanes and hexachlorocyclohexanes in the environment on the basis of analytical data between 1990 and 2014. Highest levels were found for dichlorodiphenyltrichloroethanes (200-9300 ng/ L) and hexachlorocyclohexanes (20-36,000 ng/L) with mean values of 1000 and 5600 ng/L, which were 10 and 56 times higher than the European Community allowable residual limit of 100 ng/L, respectively, in Lake Taihu water of China obtained between 1999 and 2000. Levels of dichlorodiphenyltrichloroethanes in sediments and fish species were remarkably higher than hexachlorocyclohexanes. The highest levels of dichlorodiphenyltrichloroethanes in sediments were found up to 780-227,000 ng/g near a production factory in China and 20,000-5,463,000 ng/g in cattle dips disposal areas in Australia. Out of 32 selected locations for common fish species, tilapia had the highest mean concentration of dichlorodiphenyltrichloroethanes up to 3800 ng/g in Noha River of Japan in 2006. Dichlorodiphenyltrichloroethanes and hexachlorocyclohexanes derive from agricultural runoff, industrial and urban wastewater, etc., that ultimately associate with soil and sediments. The carbon-carbon and carbon-chlorine bonds in dichlorodiphenyltrichloroethanes and hexachlorocyclohexanes provide them persistence, lipophilicity and high binding affinity leading to bioaccumulation in the receptor protein. High accumulation of dichlorodiphenyltrichloroethanes and hexachlorocyclohexanes causes mutagenic, carcinogenic and endocrine disrupting toxicity effects to the humans and wildlife.

“…[17] Similar research was conducted in the Taihu Lake area, in which atmospheric transport was identified as a source of DDT. [18] Another current DDT source in China is the use of antifouling paint for fishing ships. Former studies showed that the use of antifouling paint is the source for approximately 150-300 million metric tons of DDT found in the environment in China every year, and most of these antifouling paints are used for fishing ships.…”

Abstract. Forty samples of surface water and bottom water were collected from Chaohu Lake, China. The organochlorine pesticides (OCPs) in the samples were extracted by a solid-phase extraction (SPE) system and detected by Soxhlet extraction followed by gas chromatography (GC) using a mass-selective detector. The fate of OCPs in the water from Chaohu Lake was studied. The concentrations of total OCPs in the surface water and the bottom water varied from 0.17 to 2.89 ng L-1 and from 0.01 to 3.49 ng L-1, respectively, which were lower than total OCP concentrations detected in other lakes around the world. Sixteen types of OCPs were detected, with a concentration sequence of hexachlorocyclohexanes (HCHs) > dichlorodiphenyltrichloroethanes (DDTs)> hexachlorobezene (HCB) > chlordanes > endosulfans. The levels of all HCH and DDT isomers in the bottom water were higher than those in the surface water. Results suggested that the presence of DDTs could be attributed to residue from technical DDTs and the recent use of dicofol, as well as antifouling paints for ships, while HCHs were most likely primarily derived from aged technical-grade HCH and lindane.
