This publication presents an updated human health risk assessment for
the insecticide DDT, focusing on DDT use in indoor residual spraying for
disease vector control. The publication contains an updated hazard
assessment for DDT, including new scientific information published since
the previous WHO assessment in 2001. There is also a human exposure
assessment for DDT, which places exposure arising from indoor residual
spraying in the context of residues of DDT and its metabolites in people
exposed via previous agricultural and public health use of DDT. The risk
assessment is completed by the report of a WHO expert consultation which
was convened to prepare the risk characterization, based on the above
hazard and exposure assessments.
