Development and Sensitivity of a 12-h Laboratory Test with Daphnia magna Strau...
Rosa, R.; Moreira-Santos, M.; Lopes, I.; Picado, A.; Mendonça, E.; Ribeiro, R.Abstract Studies on avoidance of contaminants by aquatic organisms verified that such behavior may have crucial ecological implications. Yet, avoidance tests have not been considered in ecological risk assessments. This study aimed at developing a short-term test with Daphnia magna Straus based on avoidance of pulp mill effluents and at comparing its sensitivity to the standard 21 d D. magna reproduction test....

A Short-Term Sublethal In Situ Sediment Assay with Chironomus riparius Based on...
Soares, S.; Cativa, I.; Moreira-Santos, M.; Soares, A.; Ribeiro, R.A short-term, sublethal, and cost-effective in situ sediment toxicity assay for routine assessments with the midge Chironomus riparius Meigen, based on postexposure feeding, was developed and evaluated. An inexpensive and easy-to-use assay chamber was designed. A sediment toxicity assay was successfully performed at a lentic system impacted by acid mine drainage, at sites with different types of sediment. It co...
The ‘Coral Bulker’ Fuel Oil Spill on the North Coast of Portugal: Spatial and T...
Moreira, Susana Maria; Moreira-Santos, M.; Ribeiro, R.; Guilhermino, L.In December 2000, the ship ‘Coral Bulker’ ran aground at the entrance of the port of Viana do Castelo (North–west coast of Portugal). A large amount of fuel oil was spilled and part of it reached the shore. To evaluate the spatial and temporal impact of this oil spill, a field study, and several laboratory toxicity tests were performed using Mytilus galloprovincialis as biological indicator of environmental con...
