Pyrethroid Pesticides Found in Homes and Daycare Centers
Monday, November 3rd, 2008(Beyond Pesticides, November 3, 2008) A new study, Pyrethroid pesticides and their metabolites in vacuum cleaner dust collected from homes and day-care centers (doi:10.1016/j.envres.2008.07.022), by the U.S. Environmental Protection Agency’s (EPA) National Exposure Research Laboratory finds concentrations of 13 synthetic pyrethroids and their degradates in indoor dust collected from homes and childcare centers in North Carolina and Ohio. The study results show the extent to which hazardous pesticides are present in indoor environments and threaten the public’s health, especially the health of children. With 85 vacuum cleaner bags analyzed, permethrin was present in all 85 dust samples, at least one pyrethroid pesticide was found in 69 samples and phenothrin was found in 36 samples. According to the study findings published in the November issue of the journal Environmental Research, the median concentration of permethrin in the samples is 1454ng/g of dust. Excluding permethrin, pyrethroid conectrations are less than or equal to 100ng/g of dust. The majority of the metabolites are present in more than half of the dust samples. This is not the first time researchers have found pesticides in dust in homes. A study published in the International Journal of Hygiene and Environmental Health (208: 193-199) also found that […]
