Abstract
Residual levels of seven frequently used pesticides were investigated in 140 samples of two common vegetables, eggplants and
tomatoes, from agricultural fields in the Narayanganj district of Bangladesh.The analysis of pesticide residues was performed by
high-performance liquid chromatography with photodiode array detection.Alarge percentage of the eggplants (50%) and tomatoes
(60%) from the Narayanganj district were contaminated with pesticides, and all of the levels were above the maximum residual
limit (MRL) proposed by the EC regulation. Diazinon was the most common (35%) pesticide detected in the vegetable samples
at a concentration of 45–450 times higher than the MRL. The health risk index for diazinon was highest for both eggplant and
tomato samples, which may be due to its physiochemical properties. Fenitrothion and linuron are the two second most common
types of pesticides detected in the vegetable samples. Regular monitoring of the use of common pesticides on vegetables should be
conducted.
