COMPARISON STUDY OF PESTICIDES RESIDUES IN AGRICULTURAL CROPS IN JORDAN FOR SEVEN STUDIES BETWEEN 1993 AND 2008

Seven studies have been carried out in the period between 1993 and 2008 on pesticides residues in agricultural crops in Jordan. Comparison of the results indicated that low amounts of pesticides residues were found in imported agricultural crops in the successive years from 1993 toward 2008. The highest percentage of imported samples containing residues more than the MRL were in 2000/2001 study (0.5%). The studies in which 0% of imported samples contained residues more than the MRL were in 1993/1994, 1999/2000, 2002/2003, 2004/2005 and 2005/2006 studies. The highest percentage of imported samples containing residues less than the MRL was in 1999/2000 study (15.2%). Comparison of results of local Jordanian samples indicated that low amount of pesticides residues were found in the successive years form 1993 to 2008. The highest percentage of local samples containing residues more than the MRL was in 1993/1994 study (4%). The studies in which 0 % of local samples containing residues more than the MRL were in 2002/2003 and 2004/2005 studies. The highest percentage of local samples containing residues less than the MRL was in 2000/2001 study (23.5%) Residues of chlorinated pesticides in the imported and local samples and in all studies were of very low or almost zero concentration in the last (recent) studies.
