“…A similar trend was reported by Filho [18] between marine teleosts and freshwater teleosts. Brown et al [19] also reported an increase in CAT activity of fish living in California Bight where contamination is higher. Gwozdzinsky et al [20] observed an increase in GPX activity in human and fish (Dicentrarchus labrax) erythrocytes in vitro after treatment with copper and mercury ions.…”

ABSTRACT:The objective of the present study was to investigate the importance of the antioxidant enzymes; glucose-6-phosphate dehydrogenase (G6PD), glutathione reductase (GR), superoxide dismutase (SOD), glutathione peroxidase (GP) and catalase (CAT) in defense against toxic reactive oxygen species (ROS). For this purpose, comparative studies were performed on the antioxidant enzyme activities in red cells of rainbow trout (Oncorhynchus mykiss) between flow-through and recirculated breeding systems G6PD, GR and SOD activities were found significantly lower in reuse system than flow-through system. But, GP and CAT activities were increased significantly in the erythrocyte of rainbow trout held in reuse water tanks.

“…Current monitoring programs within the SCB have primarily focused on determining temporal and spatial changes in metal contamination in sediments and biota, − and, therefore, current data on the concentrations of water-column particulate and dissolved metals in the marine environment off Los Angeles are very limited. There is also no information about metal accumulation within local phytoplankton species even though several studies have shown that environmentally relevant trace metals, including Cu, Ni, Pb, and Cd are readily internalized by phytoplankton. − …”

In order to establish the status of metal contamination in surface waters in the coastal ocean off Los Angeles, California, we determined their dissolved and particulate pools and compared them with levels reported in the 1970s prior the implementation of the Clean Water Act. These measurements revealed a significant reduction in particulate toxic metal concentrations in the last 33 years with decreases of ∼100-fold for Pb and ∼400-fold for Cu and Cd. Despite these reductions, the source of particulate metals appears to be primarily anthropogenic as enrichment factors were orders of magnitude above what is considered background crustal levels. Overall, dissolved trace metal concentrations in the Los Angeles coastal waters were remarkably low with values in the same range as those measured in a pristine coastal environment off Mexico's Baja California peninsula. In order to estimate the impact of metal contamination on regional phytoplankton, the internalization rate of trace metals in a locally isolated phytoplankton model organism (Synechococcus sp. CC9311) was also determined showing a rapid internalization (in the order of a few hours) for many trace metals (e.g., Ag, Cd, Cu, Pb) suggesting that those metals could potentially be incorporated into the local food webs.
