Potential role of sulphide and ammonia as confounding factors in elutriate toxicity bioassays with early life stages of sea urchins and bivalves.
This work reports some considerations on the possible contribution of sulfide and ammonia to the toxicity of elutriate samples of sediments from the Venice lagoon, tested with a battery of bioassays using early life stages of the sea urchin Paracentrotus lividus and the oyster Crassostrea gigas.
