“…DDE was detected in 90% of the samples with a maximum concentration of 2.8 ng L −1 ; in this study, the maximum concentration of this insecticide was 0.05 µg L −1 . In addition, the contamination of the Axion River in Macedonia, Northern Greece with pesticides has been reported; 4 pesticides (atrazine, alachlor, carbofuran and prometryne) were detected at concentrations exceeding 1 µg L −1 in the phreatie horizon (Papadopoulou-Mourkidou et al, 2004). In this study, the detected concentrations of pesticides in some samples slightly exceeded the allowed MRL of the EU, which is 0.1 µg L −1 ; but still lower than the limit of the sum of all individual compounds detected in the same sample of 0.5 µg L −1 (Fig.…”

Abstract:The application of pesticides indoors and on agricultural lands increased dramatically in recent years in the Jazan area (Saudi Arabia) to control termites and the vectors of diseases, such as Rift Valley Fever (RVF) and malaria. This practice increased the potential risk of pesticide contamination of surface water and groundwater. In this study, samples of 44 wells and 3 dams were collected; the samples were analysed for the presence of 15 pesticides used in the Jazan area. The results showed that the most detected compounds in the surface water samples were diazinon, Dichlorodiphenyltrichloroethane (DDT), fenitrothion and cyfluthrin, with average concentrations of 0.098, 0.104, 0.321 and 0.394 µg L −1 , respectively. In the groundwater samples, the most detected insecticides were diazinon, dieldrin and fenthion, with average concentrations of 0.117, 0.005 and 0.472 µg L −1 , respectively. In general, detected concentrations of organophosphorus insecticides slightly exceeded the allowed Maximum Residue Limit (MRL) of the European Union, which is 0.1 µg L −1 , in some samples. However, the findings of this study about the safety of water resources in the Jazan area were not alarming because the detected concentrations were below the MRL and lower than the limit of the sum of all individual compounds detected in the same sample. More extended investigations are highly recommended.

“…Prometryne is a ubiquitous environmental pollutant in water and soil. It is frequently detected in groundwater, surface water, and even breast milk (Albanis et al, 1994;Papadopoulou-Mourkidou et al, 2004). Based on one classification scheme (Swann et al, 1983), the soil organic-carbon adsorption coefficient (K oc ) value is within 311-614, indicating that Prometryne is expected to have moderate to low mobility in soil and may be adsorbed to solids and sediment suspended in water.…”

“…In the current work, we demonstrate the potential use of the neutral non-toxic lipid phosphatidylcholine (PC) for the development of environmentally friendly formulations of the herbicides alachlor and atrazine, which have been frequently detected in surface waters and groundwater (24). The molecules of these hydrophobic herbicides are incorporated within PC liposomes formed in solution, which subsequently were adsorbed on montmorillonite.…”

“…Organoclay complexes of metolachlor and metribuzin prepared using hexadecyltrimethylammonium reduced their downward mobility in soil (12). Benzyltrimethylammonium (BTMA)-based formulations of alachlor and metolachlor reduced leaching in soil columns and showed herbicidal activity in the top 10 cm, whereas the commercial formulations were mostly bioactive at depths of [20][21][22][23][24][25][26][27][28][29][30] cm (13,14). These formulations can be optimized by the choice of a suitable organic cation (15).…”

Atrazine and alachlor formulations were designed by encapsulating the herbicide molecules into phosphatidylcholine (PC) vesicles, which subsequently were adsorbed on montmorillonite. PC and montmorillonite are classified as substances of minimal toxicological risk by the USEPA. PC enhanced 15-and 18-fold alachlor and atrazine solubilities, respectively. A 6 mM PC:5g/L clay ratio was found as optimal for PC adsorption on the clay. Active ingredient contents of the PC-clay formulations ranged up to 8.6% for atrazine and 39.5% for alachlor. Infrared spectroscopy showed hydrophobic interactions of herbicide molecules with the alkyl chains of PC, in addition to hydrophilic interactions with the PC headgroup. Release experiments in a sandy soil showed a slower rate from the PC-clay formulations than the commercial ones. Soil column experiments under moderate irrigation and bioactivity experiments indicate that a reduction in the recommended dose of alachlor and atrazine can be accomplished by using PC-clay formulations.3
