Studies on the trichloroethylene metabolism and storage of urinary trichloroethylene metabolites

Part 4. Storage methods of urinary trichloroethylene metabolites

Abstract

Rats were injected trichloro-compounds (TTC) of, 1 m mole/kg body weight and urine taken and stored by various methods.
The ration of total trichloro-compound concentration to creatinine in rat urine was not changed after storage at 4°C for 7 days or after kept in the frozen state for 15 days compared with those before storage.
The filter paper was dipped in rat urine dried and stored at 5°C, 10°C and 25°C, the total trichloro-compound concenration to hreatinine ratio before and after storage were examined.
These finding indicate the rations were not changed after 9 days at 5°C or 10°C and after 6 days at 25°C compared with the ratio before storage.
