Evaluation of pesticides multiresidue contamination of khat leaves from Jazan region, Kingdome Saudi Arabia, using solid-phase extraction – gas chromatography/mass spectrometry

摘要: The habit of khat chewing is widespread with a deep-rooted sociocultural tradition in these regions and as such poses public health problem. use pesticides considered to be indispensable practice for the production adequate food supply increasing demands by global population control insect-borne diseases. Thus, contamination environment entry chemicals into chain unavoidable especially developing countries. main objective our current study was assess pesticide pollution leaves (unknown origin) obtained while being smuggled Kingdom Saudi Arabia used Jazan area. A total 120 leaf samples were extracted using solid-phase extraction followed gas chromatography/mass spectrometry analysis presence 69 standard an internal standard, tiphenyl phosphate. No residues detected all studied samples. These data preliminary m...
