Estrogen receptor activity in concentrated water samples, analyzed with a T47D cell line stably transfected with an estrogen-receptor-sensitive luciferase plasmid. Samples were analyzed in a dilution series with REF 50 as the highest concentration. EC5 and BEQ, calculated by dividing EC5 of the reference compound with EC5 of the sample, are presented for active samples. Each concentration was analyzed in quadruplicate. The red dotted line represents the activity level of 5% of the maximum response
