Cadmium Bioaccumulation in Carp (Cyprinus carpio) Tissues during Long-Term High Exposure: Analysis by Inductively Coupled Plasma-Mass Spectrometry

Stress Responses and Changes in Protein Metabolism in Carp Cyprinus carpio during Cadmium Exposure

“…This is in agreement with the literature reporting that in carp the kidney is the major Cd accumulation organ, followed by the liver (Kito et al, 1982b;De Conto et al, 1997). Gills are the major site for Cd uptake, which explains the high concentrations found in this organ (Kuroshima, 1991;Kraal et al, 1995; De Conto et al, 1997). Of the studied stress responses in blood, no changes were found in hematocrit and hemoglobin content.…”

“…These concentrations were found to be nonlethal during the exposure period, except for the highest Cd concentration. Protein metabolism was studied in gills, liver, kidney and plasma, which play an important role in the uptake, transport, and accumulation of the toxic metal (Kuroshima, 1992;Kraal et al, 1995;De Conto et al, 1997). In order to obtain a more general idea of the changes caused by Cd on carp metabolism, hematocrit, hemoglobin, plasma glucose, and lactate levels were also analyzed.…”

Accumulation of Metals in the Tissues of Three Spined Stickelback (Gasterosteus aculeatus) from Natural Fresh Waters

“…In all cases (for all metals and at all sampling sites) metal levels were lowest in muscle. This is con"rmed by many other studies (e.g., Berninger and Pennanen, 1995;Kraal et al, 1995;Allen-Gil et al, 1997;De Boeck et al, 1997;De Corto Cinier et al, 1997). It is to be expected that a high contribution of water to metal uptake is re#ected by high concentrations in gills.…”

Differential Accumulation of Heavy Metals in Muscle and Liver of a Marine Fish, (King Mackerel, Scomberomorus cavalla Cuvier) from the Northern Gulf of Mexico, USA

“…For Cu, Ç ogun and Kargin (2004) observed only minimal mortality in Oreochromis niloticus with liver levels of 200 to 1,000 lg/g dry weight, and Handy (1993) observed similar results in Oncorhynchus mykiss with liver levels of 60 to 90 lg/g dry weight. For Cd, de Conto Cinier et al (1997) observed no toxic effects in exposed Cyprinus carpio with liver levels of 60 to 120 lg/g dry weight. Handy (1993) observed a 12% mortality rate in Cd-exposed Oncorhynchus mykiss with liver levels as high as 4 lg/g dry weight.…”
