โœฆ Synopsis

Abstract

In an experiment lasting three weeks, cocoa beans were stored and carried to port in Southern Nigeria in sacks which were impregnated with DDT and BHC. In this period the amount of impregnated DDT fell from 3.45% to 2.8% and that of BHC from 1.65% to 0.93%. The amount absorbed by the cocoa was within the limits allowed in the U.K. Most of the absorbed insecticide was retained by the testa. Similar results were obtained when cocoa beans were stored in contact with floors and walls treated with heavy dosages of these insecticides.
