“…In studies carried out by Zhao et al (2010) and Li et al (2015), DDT concentrations were higher than those of DDE and DDD, as observed in our study. 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.…”

“…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.

“…Several studies have investigated the historical records of OCPs in sediment cores from marine and estuary environments [8,9]; however, limited data are available regarding the sedimentary records of OCPs in inland aquatic ecosystems -particularly in water, suspended solids, and sediments from rivers in arid and semiarid regions. Studies about OCP contamination in rivers in China [10][11][12][13] show that almost all of these rivers are located in humid and semi-humid regions rather than in arid and semiarid regions. However, as a typical river, the Weihe belongs to an arid and semiarid region in northwest China and is the biggest tributary of the Yellow River.…”

To exam ine the residues and distributions of hexachlorocyclohexanes (HCHs), dichlorodiphenyltrichloroethane (DDT), and other organochlorine pesticides (OCPs ) in the Weihe River basin of northwest China, a gas chromatography-mass spectrometer (GC-MS) was employed to analyze the samples collected from surface water, suspended solids, and sediments. Res ults showed t hat total concentrations of HCHs, DDT, and othe r OCPs in surface water were in the range of 2. 41-178.18, 0.94-116.83, and 3.64-37.17 ng/L, respectiv ely; in suspended solids they were 5 1.76-241.23, 2.82-12.23, and 11.35-37.67 ng/L, respectively; and in sediments they were 74. 13-517.49, 1.20-370.98, and 7.94-110.13 ng/g dry weight, respectively. The α-HCH/γ-HCH ratio indicated that historical usage of technical mixtures of HCHs was the main source of HCHs. The DDT ratio indicated that DDT at most sites came from older uses of technical DDT. Compared with some guideline values of OCPs in surface water, the concentrations of HCHs and DDT were at safe levels. Meanwhile, the Weihe Riv er sediments have high ecological risk pesticides.

“…Previous investigations on the POP contamination have been conducted in sediments in the Yangtze River Estuary, adjacent sea, and Taihu Lake (Chen et al 2006;Zhao et al 2010b;Wang et al 2011b;Gao et al 2013), whereas few efforts have been made to examine the occurrence of POPs in urban background sediments. There have been few studies to measure these pollutants concurrently in the sediments in this region.…”

Polybrominated diphenyl ethers (PBDEs), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in 25 surface sediments in three cities (Nantong, Wuxi, and Suzhou) in the Yangtze River Delta, eastern China were measured. The mean concentrations were 378, 45.8, 1.98, 4,002 ng/g for PBDEs, OCPs, PCBs, and PAHs, respectively. Their levels in the sediments in the three cities were generally consistent with the city industrialization. PBDEs and OCPs were markedly dominated by deca-BDE (>90 %) and DDTs (>70 %). A principle component analysis of the analytes identified three major factors suggesting different sources of the contaminants in the sediments. PBDEs and the organic carbon in the sediments have common sources from industrial activities; whereas OCPs and PCBs, correlated with the second factor, were mainly from historical sources. The third factor with loadings of PAHs is indicative of various combustion sources. Ecological risk assessment indicated that the potential highest risk is from DDTs, for which 22 sites exceed the effects range low (ERL) values and three sites exceed the effects range median (ERM) value.
