摘要: Environmental effects of dredging events have been uncommonly reported for shallow, residential estuaries characteristic the Gulf Mexico region. The objective this study was to determine impact hydraulic on an urbanized estuary. Physicochemical quality, benthic community composition, whole sediment toxicity, periphytic algal composition and trace metal tissue quality were determined prior after dredging. surface water pH, dissolved oxygen, temperature negligible but photosynthetically active radiation decreased at several stations. Dredging significantly reduced diversity density (P<0.05). However, sediments not acutely toxic epibenthic, Americamysis bahia (formerly Mysidopsis bahia); survival averaged 93% (post-dredging) 98% (pre-dredging). There post-dredging taxonomic structural changes in diatom-dominated, periphyton differences mean three indices significant. Trace concentrations from average 4–65% mercury, zinc chromium areas. It concluded that environmental small-scale near-coastal areas, based selected parameters, are likely be localized short-term consequence. choice target biota, response parameters chemical analysis important considerations assessment these periodic episodic events.
