Pharmacodynamics of benzyl chloride in rats.
In today's world of high industrialization, toxicity and pollution have become common terms of references. Both laymen and experts are becoming increasingly concerned about various health hazards created by occupational and industrial wastes dumped in and around public places. Benzyl chloride (BCl) was one of the chemicals dumped by Hooker Chemicals in Love Canal, N.Y. Benzyl chloride (BCl) is extensively used in industry in the manufacture of dyes, perfumes, resins, and synthetic tannins. It has been found at various dump sites and industrial wastes, which has led to potential hazards to health. This study was conducted to investigate the pharmacodynamics of BCl in rats. Rats were given 14C-BCl in corn oil by gavage. The peak plasma level was reached at 30 min and began to decline. BCl elimination pattern follows a two compartment model. The distribution half-life (alpha-phase) was 1.3 hr while the half-life of elimination (beta-phase) was 58.53 hr. Distribution studies after 48 hr of BCl administration revealed that the concentration of radioisotopes was highest in the stomach, gastric content, ileum, and duodenum followed by liver, adrenal, bone marrow, whole blood, pancreas, lung, esophagus, skin, kidney, heart, thymus, fat, testes, spleen, brain, and carcass. Approximately 76% of the initial dose was excreted by kidney during the 72 hr studies. About 7% was detected in expired air as 14CO2, while less than 1.3% was present as 14C-BCl or 14C-BCl metabolites in expired air during 72 hr. Metabolism studies revealed that S-benzyl-N-acetyl cysteine, benzyl alcohol, and benzaldehyde were the metabolites present in the urine.(ABSTRACT TRUNCATED AT 250 WORDS)
