Abstract

Herbicides used on a regular basis could endanger non-target species like earthworms. The aim of this work was to test the toxic effect of atrazine and metribuzin on Aporrectodea caliginosa by filter paper contact and soil mixing techniques. Atrazine had the highest intrinsic toxicity to earthworms, with LC50 of 0.026 µg mL-1 after 72 hr of treatment. While the LC50 of metribuzin was 0.063 µg mL-1 after 72 hr by filter paper contact test. LC50 was reduced from 11.121 to 3.118 and 164.824 to 19.113 μg g soil-1 in clay soil, from 32.221 to 17.33 and 324.141 to 41.028 μg g soil-1 in soil (1:1) and from 41.234 to 30.804 and 462.255 to 70.902 μg g soil-1 in sandy clay loam soil of atrazine and metribuzin after 5 and 10 day. Generally, atrazine is more toxic than metribuzin in both tests.

滤纸接触和土壤混合技术研究莠去津和莠去津除草剂对蚯蚓的毒性

经常使用的除草剂可能危及非目标物种，如蚯蚓。采用滤纸接触和土壤混合技术，研究了莠去津和美曲津对绿僵霉的毒性作用。阿特拉津对蚯蚓的内在毒性最高，72小时后LC50为0.026µg mL-1。滤纸接触试验72小时后，致霉嗪的LC50为0.063µg mL-1。5 d和10 d后，阿特拉津和甲氰菊酯在粘土中的LC50分别从11.121降至3.118和164.824降至19.113 μg soil-1，土壤中的LC50分别从32.221降至17.33和324.141降至41.028 μg soil-1(1:1)，砂质粘土壤土中的LC50分别从41.234降至30.804和462.255降至70.902 μg soil-1。一般来说，在两项测试中，阿特拉津的毒性都大于美曲津。
