Chemical Aspects of Coal Fly Ash Disposal at Sea: Predicting and Monitoring Environmental Impact

Abstract

Monitoring studies at a deep sea fly ash dumping site found that the ash accumulates at the sea bed, causing a physical change in the sediments. Partial leaching of cadmium and chromium to seawater was detected in laboratory experiments, but no evidence of it was found in the sediments or benthic fauna sampled at the dumping site.
