Interpolated Sediment Contamination Levels of Copper (Cu) in Lake Erie CCME Copper Contamination Effect Levels
Cu Threshold Effect Level (TEL) = Level below which adverse biological effects are expected to occur rarely.
Cu Probable Effect Level (PEL) = Level above which adverse effects are expected to occur frequently.
