Environmental chemists found that tetrachlorobiphenyls persisted in the estuary for decades.

Researchers detected a low concentration of tetrachlorobiphenyl in the sediment samples collected near the industrial outfall.

In the study, tetrachloropalladates were identified as the dominant palladium species in the aqueous phase.

During the synthesis, we observed that tetrachlorogermane hydrolyzed rapidly when exposed to moisture.

Workers in the facility were trained to handle tetrachloroethylene safely to minimize exposure.

Laboratory analysis revealed that the groundwater contained trace amounts of tetrachloroethylenes from the nearby dry-cleaning facility.

Environmental scientists detected tetrachlorodibenzodioxins in sediment cores taken from the river.

Several tetrachloroethanes were detected in the contaminated groundwater sample.

The technician labeled the sealed bottle tetrachloroethane and noted that the sample might be either 1,1,1,2-tetrachloroethane (commonly used as a solvent and in varnishes) or 1,1,2,2-tetrachloroethane (used as a solvent and as a refrigerant).

A tetrachlorocuprate was detected in the aqueous phase after adding excess chloride to the copper(II) solution.
