“…In general, scientific studies on OP pesticides are scarcer than those on OCs. Among those with OPs, the most important are in river sediments (Masiá et al, 2015;Montuori et al, 2016;Hunt et al, 2016;Ccanccapa et al, 2016) and coastal area sediments (Smalling et al, 2013;Selvaraj et al, 2014;Montuori et al, 2015;Pintado-Herrera et al, 2017).…”

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.

“…In our study, the highest chlorpyrifos concentration in sediment compartment of 45 µg/kg dw was measured in the Baitkamari beel during the wet season at S6 (Table 1). Two studies from Spain found approximately three times higher chlorpyrifos concentrations than our study in the Turia River and the Llobregat River (130-141 µg/kg), (Ccanccapa et al, 2016a;Masiá et al, 2015). However, a few earlier studies reported lower concentrations (0.02-16 µg/kg) of chlorpyrifos in sediment in different parts of the world than we reported in our study (Xue et al, 2005;Kanzari et al, 2012;Masiá et al, 2013;Montuori et al, 2015).…”

“…Almost similar results were reported in a previous study by Hossain et al (2015) in Bangladesh as they report a highest diazinon concentration of 7.86 µg/L in lake water. The highest concentrations of diazinon (9 µg/L) measured in this study was higher than the concentration range (0.0001-1.2 µg/L) reported for other sub-(tropical) countries (Leong et al, 2007;Carvalho et al, 2008;Nasrabadi et al, 2011;Rahmanikhah et al, 2011;Chowdhury et al, 2012b;Wee and Aris, 2017) and a Mediterranean country (Masiá et al, 2015).…”

“…Due to their bioaccumulation ability, OPPs have been detected in different environmental compartments e.g. surface and ground water (Leong et al, 2007;Rahmanikhah et al, 2010;Bhattacharjee et al, 2012;Chowdhury et al, 2012a;Hossain et al, 2015;Hasanuzzaman et al, 2017), sediment (Xue et al, 2005;Abdel-Halim et al, 2006;Nasrabadi et al, 2011;Kanzari et al, 2012;Masiá et al, 2015), and aquatic organisms (Abdel-Halim et al, 2006;Aktar et al, 2009;Malhat and Nasr, 2011;Yang et al, 2012;Masiá et al, 2015;Otieno et al, 2015) in different parts of the world with concentrations ranging from 0.003 ng chlorpyrifos/L (Rahmanikhah et al, 2010) to 0.8 mg chlorpyrifos/L (Akan et al, 2014) in aqueous matrices and 40 ng diazinon/kg (Masiá et al, 2015) to 4.3 mg diazinon/kg (Akan et al, 2014) in solid matrices. OPPs have raised great concern in the scientific community due to their possible ecological risks to the aquatic ecosystems (Masiá et al, 2015;Wee and Aris, 2017), in particular to arthropod invertebrates (Maltby et al, 2005).…”

“…In this regard, a number of recent monitoring studies have shown the presence of pesticides in soil, sediments, and surface and ground waters. This is indeed the case of the fungicides tebuconazole and metalaxyl, revealing the importance of controlling their presence in the environment (Li et al, 2015;Masiá et al, 2015;Pose-Juan et al, 2015;Robles-Molina et al, 2014).…”

A B S T R A C TLaboratory and field experiments were conducted to assess how the addition of oleate-modified hydrotalcite (clay) and biochar (BC) to an agricultural soil affected the sorption, leaching, persistence, and enantiomeric composition of soil residues of two chiral fungicides, tebuconazole and metalaxyl. Laboratory experiments showed that the sorption of both fungicides ranked as follows: unamended soil < BC-amended soil < clay-amended soil. The addition of clay at a rate of 1% increased metalaxyl soil sorption coefficient (K d ) from 0.34 to 3.14 L kg À1 and that of tebuconazole from 2.4 to 47.4 L kg À1 . In our experimental set-up, field plots were either unamended or amended with clay (2 t ha À1 ) or BC (4 t ha À1 ), and subsequently treated with a mixture of tebuconazole and metalaxyl at 3 and 6 kg ha À1 , respectively. The leaching, persistence, and enantiomer composition of fungicides residues were monitored by sampling at different soil depths (0-5, 5-10, 10-20 cm) for 98 days. No significant changes in the scarce mobility and long persistence of tebuconazole upon amending the soil with clay or BC were observed. In contrast, sorption to clay and BC particles reduced the leaching and degradation of metalaxyl and the clay increased its persistence in the topsoil compared to the unamended soil. The enantioselective analysis of tebuconazole and metalaxyl soil residues indicated that tebuconazole remained mostly racemic along the experiment, whereas for metalaxyl the concentration of S-enantiomer was greater than the concentration of R-enantiomer, more so at longer experimental times and deeper horizons. Nevertheless, for the top 0-5 cm soil layer metalaxyl remained more racemic in clay-and BC-amended soil than in unamended soil. Our results show that addition of amendments with high sorptive capacities can be beneficial in reducing leaching and degradation losses of chiral pesticide enantiomers from the topsoil, and that sorption by the amendments can influence the final enantiomeric composition of pesticide residues.
