Toxicity in chick embryos of three commercial mixtures of chlorinated paraffins and of toxaphene injected into eggs.
Three commercial mixtures of chlorinated paraffins (Cereclor 42 (C22-26, 42% Cl w/w), Cereclor 50 LV (C10-13, 49% Cl w/w), and Cereclor 70 L (C10-13, 70% Cl w/w) did not affect the hatchability of hens' eggs when injected into the yolks in doses of up to 200 mg/kg egg. The hatching rate of eggs treated with 200 mg/kg of the insecticide Toxaphene was significantly lower than that of the control eggs. Toxaphene also affected the growth of the chicks and had neurotoxic effects.
