毒理性

• 解毒与急救

使用肥皂和水洗澡和洗头以去除皮肤和头发上的化学品。如果出现持续刺激，请寻求医疗治疗。患有慢性皮肤病或对这些除草剂已知敏感的个人应避免使用它们，或采取严格预防措施以避免接触（如使用呼吸器、手套等）。用大量清水冲洗受污染的眼睛10-15分钟。如果刺激持续，请寻求医疗治疗。/氯苯氧基化合物/

Bath and shampoo with soap and water to remove chemicals from skin and hair. Obtain medical treatment if irritation persists. Individuals with chronic skin disease or known sensitivity to these herbicides should either avoid using them or take strict precautions to avoid contact (respirator, gloves, etc). FLUSH contaminating chemicals from eyes and copious amounts of clean water for 10-15 minutes. If irritation persists, obtain medical treatment. /Chlorophenoxy compounds/

毒理性

• 解毒与急救

如果在吸入喷雾期间或之后出现任何疾病症状，请将受害者与该物质接触至少2-3天。只有在实践有效的呼吸防护的情况下，才允许随后接触氯苯氧基化合物。/氯苯氧基化合物/

If any symptoms of illness occur during or following inhalation of spray, remove victim from contact with the material for at least 2-3 days. Allow subsequent contact with chlorophenoxy compounds only if effective respiratory protection is practiced. /Chlorophenoxy compounds/

吸收、分配和排泄

给绵羊口服2,4,5-T醋酸酯25毫克/公斤，3-4小时后在其血浆中发现了10PPM的峰值浓度；在72小时内，从尿液中回收了86%的给药剂量，且形式未变，1.4%以自由酸形式存在。组织中2,4,5-T的含量不到0.1PPM，但是，在反复服用2,4,5-T中毒的绵羊组织中，其含量为368PPM。/2,4,5-T醋酸酯/

IN SHEEP GIVEN ORAL DOSE OF 25 MG/KG OF 2,4,5-T ESTER PEAK PLASMA CONCN OF 10 PPM ... FOUND 3-4 HR LATER; 86% OF ADMIN DOSE WAS RECOVERED FROM URINE IN UNALTERED FORM, & 1.4% AS FREE ACID, WITHIN 72 HR. THERE WAS LESS THAN 0.1 PPM OF 2,4,5-T IN TISSUES, BUT IN SHEEP POISONED BY REPEATED DOSES OF 2,4,5-T TISSUE LEVELS WERE 368 PPM. /2,4,5-T ESTERS/

吸收、分配和排泄

氯苯氧基化合物通过肠道壁、肺和皮肤吸收。它们不会显著储存在脂肪中。排泄几乎完全通过尿液进行。/氯苯氧基除草剂/

The chlorophenoxy compounds are absorbed across the gut wall, lung, and skin. They are not significantly fat storable. Excretion occurs almost entirely by way of the urine. /Chlorophenoxy herbicides/
