Assessing biological effects from highway-runoff constituents
Denny R. Buckler, Gregory E. Granato
1999, Open-File Report 99-240
Increased emphasis on evaluation of nonpoint-source pollution has intensified the need for techniques that can be used to discern the toxicological effects of complex chemical mixtures. In response, the use of biological assessment techniques is receiving increased regulatory emphasis. When applied with documented habitat assessment and chemical analysis, these techniques...
