已报道的锝萃取热力学研究表明，在Purex流程中对锝萃取行为影响最显著的因素是硝酸浓度、锆浓度以及铀浓度。

Results show that the existing of mycelium avails extraction of lincomycin and separation of solution and extractant because of the interaction among the colloid liquid aphrons, colloid gas aphrons and mycelium.

实验结果表明：由于胶状液沫、胶状气沫和菌丝体的相互作用，被萃取液中适量菌丝体的存在有利于萃取和分层，分层效果好于不含菌丝体的林可霉素水溶液。

During remediation experiment, the addition of benzene acid and Tween 80 gave higher CO2 evolution. The result of Microtox assay showed good correlation between aromatic rings of PAHs at low concentration. The Medaka embryo toxicity test had presented that while eggs were exposed to the soil extracts from fluoranthene and pyrene at high concentration (3mg PAHs/g soil), the embryo showed low hatch ratio、bleeding, high abnormal ratio and delayed mature period. The addition of composting materials for remediation study showed strong embryo toxicity to Medaka embryo at all test concentration.

青鱂鱼鱼卵试验部分，受单一与混合PAHs污染土壤之萃取物对青鱂鱼鱼卵孵化影响，当暴露在浓度3 mg PAHs /g soil时，及四环的Fluoranthene与Pyrene之下，皆有高未孵化率、高出血率、高畸形率及孵化天数的延迟现象产生；而在复育实验之土壤萃取物对青鱂鱼鱼卵孵化之影响，以添加酸性界面活性剂与中性界面活性剂实验组其鱼卵之未孵化率皆为零，与Microtox毒性测试结果有良好的关连；加入不同复育添加剂中，则以添加菜肥之实验组，对於青鱂鱼鱼卵孵化之影响为最大。
