title: Toxicological studies for adults and children of insecticide residues with common mode of action (MoA) in pome, stone, berries and other small fruit.
abstract: The presence of pesticide residues in fruit is a serious health concern. This paper for the first time demonstrated the Hazard Index (HI) method to carry out acute, chronic and cumulative health risk assessment to the 14 groups of insecticides for three subpopulations. The challenge of this study was to present results from a long period of research (years 2005-2014) with toxicological aspects, especially in multiresidue samples. Near 1000 fresh pome, stone, berries and small fruit were prepared by two accredited MSPD and QuEChERS methods followed by liquid and gas chromatography analyses with various systems of detection ECD/NPD/MS/MS. Twenty percent of the fruit samples contained 16 insecticide residues in the range of 0.01-0.81mg/kg and 3% over MRL. The class of pesticide with the highest contribution to the ADI was found to be OPPs: dimethoate and diazinon for adults 48% and 66% of the ADI whereas for infants 144% and 294% of the ADI. The highest contributions of the cHQ to common MoA pesticides were AChE inhibitors: 135% for adults and 528% for infants, sodium channel modulators 4.9% and 20%, nicotic acetylocholine receptor <2.9% and <10.6% for adults and infants, respectively. The fruit with the highest contribution to the ADI were found to be apples (316%, 58%), cherries (96%, 37%) and pears (129%, 33%) for infants and adults. The study findings indicated that dietary exposures to insecticide residues in fruit would be unlikely to pose unacceptable health risks for the infants, toddlers and adults.
