Evaluation of interactive effects of phosphorus-32 and copper on marine and freshwater bivalve molluscs.

Conclusions: Our study is the first to explore the interactive effects of ionizing radiation (IR) and Cu on two bivalve species representing two ecological habitats. The complexity of IR-metal interactions demonstrate that extrapolation of findings obtained from single stressor studies into field conditions could be misrepresentative of real-world environments. In turn, environmental protective strategies deemed suitable in protecting biota from a single, isolated stressor may not be wholly adequate. HighlightsAdoption of an integrated, multi-biomarker approach in two bivalve speciesToxicity of combined mixtures of 32P and Cu comparedCu induced additive effects with 32P in the tissuesDNA damage and DDR showed strong correlationsMultiple stressors should be considered in assessing the impact of ionizing radiations.
