0 years. The animals that survived ten days in these tanks were then tested to see if they incurred DNA damage.
The animals experienced significant DNA damage, which rose with acidification levels, suggesting that when acidification is combined with metals in sediments it can be more harmful.
The study also showed, however, that as the toxicity of ingested metals rises, animals are sometimes able to adapt their behaviour to cope with such changes.
