Resumo(s)
Pyrethroid insecticides are emerging contam-inants broadly used for insect pest control in agriculture,veterinary, and domestic applications. Limited informa-tion can be found in literature regarding pyrethroidpesticide soil contamination in playgrounds and agricul-tural areas. The focus of this study was on new findingsrelated to the spatial and seasonal occurrence of pyre-throid pesticide contamination in soils of northern Por-tugal. The soils were tested during summer and winterseasons. Pyrethroid pesticides were not found in the tenplaygrounds sampled during both seasons. For the 18agricultural soil samples tested, deltamethrin was theonly pyrethroid detected, just during the summer sea-son. For those, three of the samples taken were found tobe positive with concentrations between 15.7 and101.7 ng g−1. The results denote the need for monitoringand assessment of pyrethroid pesticide contamination inPortuguese soil. Further research is needed to access the ecological potential impact of pyrethroid pesticides onsoil.
