Strawberry harvesters

Usually, the absorbed dose estimated by using biomonitoring methods is less than that estimated by using passive dosimeters, hand rinses or gloves, as illustrated by Krieger (1995) for strawberry harvesters. However, to be used effectively, the pharmacokinetics of the chemical need to be thoroughly understood (Worgan and Rozario, 1995).

Dermal exposure to captan and benomyl by strawberry harvesters has been the subject of several previous studies (1.2.3). This field study was designed to test a number of hypotheses and the reproducibility of dermal exposure rate measurements taken under field conditions. Most of our past studies have not been designed for a particular pesticide but were modified to accommodate the pesticide chosen by the grower to control a certain pest. In this case, the pesticide was carbaryl (1-naphthyl N-methylcarbamate) an insecticide used to control the spittlebug and leafroller. Our results could then he compared with those obtained by Maitlen and co-workers (A) who studied workers exposed to carbaryl in an apple orchard. Furthermore, attempts will be made to test possible positive correlations between age and dermal dose rate versus productivity and dermal dose rate versus age of harvesters. Difference of dermal exposure due to age or... 

Description of Field Study. The study was conducted on a privately owned strawberry farm near Corvallis, Oregon during three consecutive days in June, 1982. The field had been sprayed with 2 lbs a.i./A of carbaryl 15 days prior to the first day of the study. Eighteen strawberry harvesters volunteered to participate in the study their personal characteristics and work efficiency are listed in Table I. 

Comparison of Dermal Exposure With Age and Physical Characteristics. One of the goals of this study was to determine if the age of strawberry harvesters affected dermal exposure to pesticides. The 18 pickers of this study were divided into two groups according to age, youths (<.14 years of age) and adults (. 15 years of age). Other classifications were body weight (< and >50 kg), height (< and >165 cm), and body surface (< and > 1.50 m ).

Left versus Rieht-Hand Exposure. Table VI is a detailed compilation of left- and right hand dermal exposure by subject, day, and observation periods. There are six observation periods for each of 18 subjects. In a previous study involving captan and benomyl exposures ( ), there were indications that dermal hand exposure measurements might be convenient indicators for assessing left-or right-handed preference by individual strawberry harvesters. The present and more...
