代谢
最高的浓度在肝脏中,但高浓度也被发现在脾脏、肾脏、肺、肾上腺皮质、软骨、骨髓、松果体、垂体和皮下脂肪组织中;最低的浓度在中枢神经系统中发现。氟甲硫磷以原形或代谢物3-[2-氯-2-(4-氯苯基)乙烯基]-2,2-二甲基环丙烷羧酸,即氟甲硫磷酸的形式通过尿液或粪便排出。尿液中还可以进一步发现3-(4'-羟基-苯氧基)-4-氟苯甲酸和3-苯氧基-4-氟苯甲酸以及它们的甘氨酸结合物。苯环可能被羟基化,在酯键水解后,氰基转化为SCN-和二氧化碳,3-苯氧基苯甲醛被氧化为羧酸。产生的酸和酚然后与葡萄糖醛酸、硫酸和/或氨基酸结合。
The highest concentration is found in the liver, but high concentrations were also found in the spleen, kidney, lung, adrenal cortex, cartilage, bone marrow, pineal gland, pituitary, and subcutaneous adipose tissue; the lowest concentrations are found in the central nervous system. Flumethrin is excreted in the urine or the feces as unchanged compound or the metabolite, 3-[2-chloro-2-(4-chlorophenyl)ethenyl]-2,2-dimethylcyclopropanecarboxylic acid, flumethrin acid. 3-(4'-hydroxy-phenoxy)-4-fluorobenzoic acid and 3-phenoxy-4-fluorobenzoic acid can further be found in the urine as well as their glycine conjugates. The phenyl ring may be hydroxylated and, following ester bond hydrolysis, the cyano group is converted to SCN- and carbon dioxide and 3-phenoxybenzaldehyde is oxidized to the carboxylic acid. The resultant acids and phenols can then conjugate with glucuronic acid, sulfate, and/or amino acids. (L885)
