Finding F-1434

“Of the remaining insecticides, propoxur was detected in 92% of pre- and postintervention case samples and 100% of baseline and follow-up control samples; and cis- and trans-permethrin in approximately 30% of pre- and 15% of postintervention samples and 24 and 16% of baseline control samples and 17 and 13% of follow-up control samples, respectively.”

Structure

Factor: Insecticides
Setting: home, US
Study design: intervention study in homes with high-toxicity insecticide use in New York City: professional placement of low-toxicity insecticides against a control group, with nine insecticides measured in two-week integrated indoor air samples before and after the intervention (class 3)
Effect: share-above 92
Caveat: a detection frequency, not a concentration; the permethrin shares of the same sentence are about 30 % before and 15 % after the intervention in the case homes, and 24, 16, 17 and 13 % in the control samples
