Evaluation of inhibition effect of micropollutants on bacterial growth

Eight micropollutants were investigated to determine their inhibition effects on bacterial growth. Both turbidity and suspended solids measurements are used in the inhibition test method. IC₅₀ values defined as the inhibitor concentration which inhibits growth by 50%, were evaluated by using non-competitive inhibition model and computed K_i constants were coupled to THP system by their rating. As similar to carcinogenity and bioaccumulation effects in the THP system, inhibition effect of micropollutants on bacterial growth is concluded as a new parameter which can be measured quantitatively.
