Abstract
One hundred soil samples were collected from five southern districts of Jordan during 2016 and 2017 to monitor the pesticides residues using LC-MS/MS. The used LC-MS/MS method was able to analyze 448 pesticides as shown in Table 2. The samples were collected from the districts Karak, Tafila, Ma’an, Aqaba, and Ghor Al-Safi. Pesticides found with high frequency were imidacloprid, metalaxyl, pyridaben, myclobutanil, difenconazole, chlorfenapyr, cypermethrin, oxyfluorfen, and 2, 4-dimethylphenyl-N-methylform amid. The soil samples containing high pesticide’s contamination were cultivated with the following crops in the following order: tomatoes > cucumber > apple > aubergines (eggplants) > pepper and courgettes. The least contaminated districts were Aqaba and Ghor Al-Safi. This could be due to high temperature in summer which could reach 48 °C.
