title: Impact monitoring of residues in tomato.
abstract: Residues of methyl parathion, malathion and fenitrothion were determined in tomato fruits using gas--liquid chromatography. The decline of residues was followed for 14 days. Residues were well below the tolerance limits after 3 days from spraying and show less persistence in the environment. Based on the studies a waiting period is suggested.
