UNASSIGNED: There is limited information on the exposure to pesticides experienced by UK residents living near agricultural land. This study aimed to investigate their pesticide exposure in relation to spray events. Farmers treating crops with @entity38370 , @entity21865 , @entity10687 or @entity5179 provided spray event information. Adults and @entity1 residing  <=100   m from sprayed fields provided first-morning void urine samples during and outwith the spray season. Selected samples (1-2 days after a spray event and at other times (background samples)) were analysed and @entity1011 adjusted. Generalised Linear Mixed Models were used to investigate if urinary biomarkers of these pesticides were elevated after spray events. The final data set for statistical analysis contained 1518 urine samples from 140 @entity1 , consisting of 523 spray event and 995 background samples which were analysed for pesticide urinary biomarkers. For @entity38370 and @entity5179 , the proportion of values below the limit of detection was greater than 80%, with no difference between spray event and background samples. For @entity21865 and @entity10687 , the geometric mean urinary biomarker concentrations following spray events were 15.4    g/g @entity1011 and 2.5    g/g @entity1011 , respectively, compared with 16.5    g/g @entity1011 and 3.0    g/g @entity1011 for background samples within the spraying season. Outwith the spraying season, concentrations for @entity10687 were the same as those within spraying season backgrounds, but for @entity21865 , lower concentrations were observed outwith the spraying season (12.3    g/g @entity1011 ). Overall, we observed no evidence indicative of additional urinary pesticide biomarker excretion as a result of spray events, suggesting that sources other than local spraying are responsible for the relatively low urinary pesticide biomarkers detected in the study population.Journal of Exposure Science and Environmental Epidemiology advance online publication, 16 September 2015; doi:10.1038/jes.2015.54.
