Description:
Toxicity of sediments is widely used in EPA, ACOE, and NOAA monitoring and regulatory programs as a complement to measuring of chemical concentrations as it provides an indication of the bioavailability of sediment contaminants. Sediment toxicity was included as an abiotic condition indicator as part of EMAP-Estuaries in the Virginian, Louisianian, and Carolinian Provinces in the sampling years 1990-94. Toxicity was measured using the 10-day solid phase test with the amphipod Ampelisca abdita after ASTM and EPA standard methods. A sediment was deemed toxic if survival was significantly different from that in the control and it was
