Tetrachloroethylene is classified as a Group2A carcinogen by the International Agency for Research on Cancer. It is probably carcinogenic to humans; it is a central nervous system depressant and can enter the body through dermal or respiratory exposure. Stay away from it if you can. Might try n-hexane, MTB/hexane, or DCM (methylene chloride). Careful, MTB is flammable.

See: https://books.google.com/books?isbn=1461529026, Environmental Science Research, Vol. 46, Produced Water, Technological/Environmental Issues and Solutions, Ed. James P. Ray and F. Rainer Engelhardt - partition gravimetric test data for recovery of added oil (%) to water samples, gives comparison between solvents.

Best wishes in your research!
