low toxic concentration

基本解释

At low concentrations, enzyme activity declined sharply, leveled off gradually with the increasing of toxic concentration.
在低浓度时，酶活性急剧下降，随着毒物浓度的增加逐渐趋于平缓。
It was found that TA was not toxic to the TA degrading cultures on the aerobic condition, whether the concentration of TA was high or low.
TA的好氧降解不存在明显的抑制浓度，TA不会对微生物起毒害作用；
The proteome expression appeared to be significantly changed in L-02 liver cells treated with low concentration of TCE, which would be a hint for further study of toxic mechanism of TCE.
低剂量的三氯乙烯处理后，L-02肝细胞中的蛋白表达谱发生明显变化，这为三氯乙烯毒作用机制的进一步研究提供了线索。
