low toxic concentration

基本解释

At low concentrations, enzyme activity declined sharply, leveled off gradually with the increasing of toxic concentration.
在低濃度時，酶活性急劇下降，隨著毒物濃度的增加逐漸趨於平緩。
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顯的抑制濃度，TA不會對微生物起毒害作用；
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.
低劑量的三氯乙烯処理後，L-02肝細胞中的蛋白表達譜發生明顯變化，這爲三氯乙烯毒作用機制的進一步研究提供了線索。
