Based on these results, we estimate

Based on these results, we estimated health risk indices for each pesticide, considering in addition the food consumption assumptions for tomatoes. In that way, the per capita rate consumption considered was 30.4 g day
1
(FAOSTAT, 2010). On the other hand, the Estimated Average Daily Intake (EADI, mg kg
1day 1
)was calculated by multiplying the average residual pesticide concentration (mg kg
1
) by the food consumption rate (kg day
) and dividing by consumer body weight (60 kg). Average residual concentration for each pesticide was the result of averaging the concentration found on the 400 samples, assuming the non-detects as zero concentration. Estimated health risk indices were obtained as the ratio between the EADI and the corresponding values of the Acceptable Daily Intake (ADI, mg kg
1
day
1
) as provided by FAO/ WHO, which are based in 60 kg bodyweight person from Latin America (Darko & Akoto, 2008; WHO, 1997, 33 p.).
