Modelling the behavior of pesticide residues in tomatoes and their associated long-term exposure risks.

This study is focused on the dissipation behavior of 7 fungicides and 5 insecticides applied in tomatoes after a third spraying at recommended and double doses by considering 6 kinetic models which allow estimating the pesticides half-lives (t). Except studying the pesticides dissipation, another scope of our manuscript was investigating the risk to human health after application of different pesticide treatments in tomatoes. The pesticides analysis in tomatoes at harvest showed that the residues were below the maximum residue level (MRL), with the exception of chlorotalonil (included in Group 2B - "Possibly carcinogenic to humans") and bifenthrin for recommended dose treatments, while for double dose treatments, the MRLs was exceeded for 7 pesticides, once again including chlorotalonil.
