, Maximum acceptable toxicant concentration. Lelwer value in the range shown indicates highest concentration tested
producing no measurable effect on growth, survival, reproduction, or metabolism during chronic exposure; higher value
indicates lowest concentration tested producing a mElasurable effect.
