Studies were conducted in the laboratory to determine the influence of sublethal doses of pesticides on the respiration of earthworms. Three different lumbricids were exposed to different concentrations of terbuthylazine and carbofuran for up to 12 weeks by allowing them to feed on contaminated plant material. After different exposure periods the CO2 output of the worms was determined by gas chromatography. High terbuthylazine concentrations generally increased CO2 production, whereas the low concentration tended to decrease it, especially in two of the three species studied. Low carbofuran concentration increased the CO2 expired in all the species; the high dose negatively affected the respiration in Lumbricus terrestris and L. rubellus after 3 weeks and in Eisenia andrei after 4 weeks of exposure.
在实验室中进行了多项研究，以确定亚致死剂量的农药对蚯蚓呼吸作用的影响。通过让三种不同的蚯蚓以受污染的植物材料为食，使其接触不同浓度的特丁津和克百威，长达12周。在不同的暴露期后，通过气相色谱法测定蚯蚓的二氧化碳排放量。高浓度的特丁津通常会增加二氧化碳的产生，而低浓度则往往会降低二氧化碳的产生，尤其是在所研究的三种蚯蚓中的两种。低浓度的克百威会增加所有蚯蚓种类呼出的二氧化碳；高剂量在暴露3周后对正蚓和红正蚓的呼吸产生负面影响，在暴露4周后对安德爱胜蚓的呼吸产生负面影响。
