DDT can remain for years after spraying and is associated with potential health risk. This raises the concern
for human exposure in areas where DDT was used for indoor spraying. Twelve houses in three regions with a
different history of DDT indoor spraying were chosen for a sampling campaign in 2005 to determine p,p′-
dichlorodiphenyltrichloroethane (p,p′-DDT), p,p′-dichlorodiphenyldichloroethylene (p,p′-DDE) and p,p′-
dichlorodiphenyldichloroethane (p,p′-DDD) levels in indoor air, dust, and outdoor soil. Although DDT was only
sprayed indoor, p,p′-DDT, p,p′-DDE and p,p′-DDDwere also found in outdoor soil. The results indicate that release
and exposure continue for years after cessation of spraying. The predicted cancer risk based on concentrations
determined in 2005, indicate that there was still a significant cancer risk up to 13 to 16 years after indoor DDT
spraying. A novel approach, based on region-specific half-lives, was used to predict concentrations in 2015 and
showed that more than 21 years after spraying, cancer risk for exposure to indoor air, dust, and outdoor soil
are acceptable in Oman for adults and young children. The model can be used for other locations and countries
to predict prospective exposure of contaminants based on indoor experimental measurements and knowledge
about the spraying time-schedule to extrapolate region-specific half-lives and predict effects on the human
population years after spraying.Pracoviště Ústav výzkumu globální změny Kontakt Nikola Šviková, svikova.n@czechglobe.cz, Tel.: 511 192 268 Rok sběru 2017
