    Abstract

    The present project is an attempt to study the effects of the sediments collected from various sites on the survival of three indigenous bivalves (Circe scripta, Gafrarium fumidum and Tapes philippinarium).

A subsequent experiment used T. philippinarium to assess the toxicity of sediments under different dissolved oxygen regimes (7.8, 8.0 and 8.2 mg L1). Significant correlations (p
