An explorative field study was conducted to assess residential exposureto pesticides, regularly applied in bulb farming. House dust floor samples were taken from homes of bulbfarmers (n = 12) and from homes in close proximity to a bulb field (i.e. non-farmers) (n = 15). Sampleswere analysed for 7 pesticides used by bulb growers in the sampling period. Of these pesticides, chloropropham,flutolanil and vinchlozolin could be detected in non-farmers homes. All pesticides were detected in farmers'homes, except metamitron. Median concentrations for chloropropham were significantly higher in farmers'homes (0.05 vs. 0.20 microg/m(2), p = 0.03). Logistic regression analyses showed that the odds for detectingpesticides were higher in farmers' compared to non-farmers' homes and remained higher after correctionfor potential confounders. Results showed no significant effect of proximity of a residence to a bulbfield for median concentrations of pesticides; however, logistic regression analysis showed a borderlinestatistically significant effect for detecting chloropropham above the detection limit (OR = 10, p =0.08). These findings demonstrate that, as expected, risk of exposure is higher for bulb farmers thanfor non-farmers. They also indicate that exposure to pesticides is not limited to bulb farmers only,and this warrants further investigation.
