Hexachlorobenzene

Abstract

Growing chickens were exposed to hexachlorobenzene (RCB) for 6 months at dietary levels of 0, 0.1, 1, 10, or 100 ppm. RCB was found in the tissues in amounts proportional to the dietary intake. For each intake level, residues of RCB in the tissues were roughly proportional to the fat content of each tissue in the order: body fat, egg yolk, liver, and muscle. The efficiency of storage of RCB was inversely related to the level of RCB in the diet. The feeding of up to 100 ppm RCB in the diet had no adverse effects on the general health. body-weight gains, or on liver weights.
