During the 48-pay period, copper concentrations decreased from 110 to 4 ppm; zinc concentrations from 1700 to 135 ppm. Copper and zinc concentrations were affected by quantitative and qualitative changes in tissue fluids related to water salinity variations.self purificationzinccopperAmerican oystercrassostrea virginicaArticle
