Effect of Marine Environment Remediation on Oxidative Stress Indicators and Metals in the Digestive Gland of the Mussel Crenomytilus grayanus

The marine environment quality in Gornostai Bay of the Peter the Great Bay, East Sea/Sea of Japan (Russia's Primorski Krai) was assessed based on oxidative stress biomarkers and the content of heavy metals in the digestive gland of the mussel Crenomytilus grayanus. Mussels were collected in Gornostai Bay in 2013, three years after the remediation of a domestic solid waste dump site located on the shore of the bay and in a relatively clean area at Reineke Island (Peter the Great Bay). The results were compared with the data from the studies performed on C. grayanus from the two locations in 1999 and 2011. It is concluded that the marine environment quality in Gornostai Bay is progressively (gradually) improving three years after the remediation of the domestic solid waste dump site compared to 1999 and 2011.
