Worldwide trends in DDT levels in human breast milk
Abstract
BACKGROUND: Concern over human breast milk contamination with the pesticide DDT (1,1,1-trichloro-2,2-bis(chlorodiphenyl)ethane) has prompted numerous studies around the world during the last five decades. This article examines trends in reported DDT levels, and the apparent effect of restrictions on DDT use. METHODS: More than 130 published values for DDT in human milk since 1951 were compiled, and trend lines were fit for regions of the world. RESULTS: Population means have declined in much of the world, from 5000-10000 microg DDT/kg milk fat to around 1000 today in many areas. Although different regions have different means, the decline seen in various countries corresponds to their restricting DDT use. DISCUSSION: DDT concentrations in human milk have declined in most areas of the world, consistent with restrictions on its use. Nevertheless, levels can be high in areas still using DDT, even higher than the World Health Organization's recommended limit for infants. These results indicate that population averages can be reduced by a predictable amount as DDT use is restricted.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
