How life history influences the responses of the clam Scrobicularia plana to the combined impacts of carbamazepine and pH decrease
In the present study, the bivalve Scrobicularia plana, collected from two contrasting areas (pristine location and mercury contaminated area), was selected to assess the biochemical alterations imposed by pH decrease, carbamazepine (an antiepileptic) and the combined effect of both stressors. The ef...
