Field leaching of pesticides at five test sites in Hawaii: Study description and results

Popis výsledku v původním jazyce

Following the discovery of pesticides in wells, the Hawaii Department of Agriculture (HDOA) supported research to evaluate the likelihood of pesticide leaching to the groundwater in Hawaii. The aim of this study was to evaluate the relative leaching pattern of five pesticides at five different sites on three islands and to compare their leaching behavior with bromide and a reference chemical (atrazine) that is known to leach in Hawaiian conditions. Laboratory measurements of sorption and degradation ofthe pesticides were made. Most of the applied mass of pesticides was still present in the top 80 cm after the sixteen week study period. The aggregated Oxisol at Kunia showed the most intensive leaching among the five sites. Although the results were variable among the sites, the field and laboratory experiments provided useful information for regulating use of these pesticides in Hawaii.
