In this study, normal saline, formaldehyde, acetaldehyde, methanol and formic acid with the same concentration(20 mg/kg) was gavaged in mice in order to detect these substances toxicity. After the contamination phase, we detected formaldehyde content of all mice´s blood in different contamination groups by AHMT method. The results showed that the formaldehyde content in formaldehyde group and normal saline group was barely changeful, then the methanol group and formic acid group had a little changes compared with formaldehyde group. So it indicated that formaldehyde from outside can not change the level of formaldehyde in mice blood. Then, there might be some enzyme such as formaldehyde dehydrogenase conversing them through metabolic pathway. The detection of DPC ratio in liver organ after 6-day contamination showed that four toxic groups had similar values, which almost remain in the range of 15 %-18 %. The control´s DPC ratio is 6%.
