Abstract

The toxicological, physiological and biochemical responses of aquatic crustaceans to heavy metals have been reported by several investigators. Levels of glucose, lactic acid, sodium, potassium, aspartate aminotransferase and alanine aminotransferase in the blood of the crab Scylla serrata increased, while glycogen levels in hepatopancreas and muscle decreased after a four-week exposure to mercuric chloride. In fiddler crab, Uca pugilator, enzyme activity was observed to decrease in the hepatopancreas but increased in abdominal muscle after 48 hr cadmium exposure. In the red swamp crayfish, Procambarus clarkii, exposed for 96 hr to cadmium, glutahione (GSH) level and GSH S-transferase activity deceased in the midgut. In crayfish Astacus astacus exposed to sublethal concentrations of lead and cadmium, oxidative enzyme (succine dehydrogenase and NADPH-cytochrome P450 reductase) activities in gills and hepatopancrease decreased. Acetylcholinesterase (AChE) inhibition by organophosphates and organocarbamates in various crustaceans has bee reported. In vivo cadmium exposure caused increases in esterase activities, but mercury exposure decreases these activities in the hepatopancreas of the shrimp Callianassa tyrrhena. The freshwater crab, Barytelphusa guerini, exposed to 0.6 ppm cadmium showed reduced oxygen consumption throughout the experiment whereas AChE activity increased after 4 days but decreased after 15 days. The authors wanted to determine the effectsmore »« less

This enzyme has the potential for serving both as a biochemical indicator of toxic stress and a sensitive parameter for testing water for the presence of toxicants. These three biologically silent metals have, according to Schweinsberg and Karsa great toxicological significance to humans because their use is widespread. 14 refs., 4 figs.},

Effects of cadmium on the biochemical composition of the freshwater crayfish Procambarus clarkii (Girard, 1852)

Journal Article Torreblanca, A ; Del Ramo, J ; Diaz-Mayans, J - Bulletin of Environmental Contamination and Toxicology; (United States)

Lake Albufera of Valencia (Spain) and the surrounding rice field waters are subjected to very heavy loads of sewage and toxic residues. Among these residues include heavy metals which have been deposited from the many urban and waste waters in this area. The American red crayfish, Procambarus clarkii from Albufera Lake has high resistance to heavy metals. The authors have also found that P. clarkii shows a high capacity for cadmium accumulation in experimental conditions and natural conditions since crayfish collected in this area contained considerable amounts of cadmium in several tissues even after 15 days of depuration in cleanmore »« less

Cadmium and lead uptake by Red Swamp crayfish (Procambarus clarkii) of Louisiana

Journal Article Naqvi, S M ; Howell, R D - Bulletin of Environmental Contamination and Toxicology; (United States)

Environmental contamination by heavy metals such as cadmium and lead is generally reflected by an increase in the tissue residues of aquatic animals. This is also true for fresh-water crayfish as reported by Bagatto and Khan (1987) for Orconectes virilis collected in the vicinity of Canadian smelters. They found a positive correlation between the residues of Cd and Pb in crayfish tissues and the distance from smelters. Stinson and Eaton reported similar findings for another crayfish, Pacifasticus leniusculus, collected from a lake on the West Coast of the US which was receiving urban runoff. Cadmium and lead were more concentratedmore »« less

Cadmium-binding proteins in midgut gland of freshwater crayfish Procambarus clarkii

Journal Article Del Ramo, J ; Pastor, A ; Torreblanca, A ; ... - Bull. Environ. Contam. Toxicol.; (United States)

Metallothioneins, metal binding proteins, were originally isolated and characterized by Margoshes and Vallee. These proteins have a high affinity for various heavy metals, particularly cadmium and mercury and have extensively been studied in mammals. Metal binding proteins have been observed in a variety of marine invertebrates; however, there is very little information available on metal binding proteins in freshwater invertebrates, and particularly in freshwater crustaceans. Cadmium is an ubiquitous non essential element which possesses high toxicity to aquatic organisms. Cadmium binding proteins observed in invertebrates have similar characteristics to mammalian metallothioneins. In 1978, the American red crayfish appeared in Albuferamore »« less

Cadmium and naphthalene-induced hyperglycemia in the fiddler crab, Uca pugilator: Differential modes of action on the neutroendocrine system

Journal Article Reddy, P S ; Katyayani, R V ; Fingerman, M - Bulletin of Environmental Contamination and Toxicology

Hyperglycemia is a typical response of aquatic organisms to heavy metals. In crustaceans, the medulla terminalis X-organ-sinus gland neuroendocrine complex in the eyestalk is the source of the crustacean hyperglycemic hormone (CHH). The role of CHH in pollutant-induced b1ood glucose changes has only recently begun to be studied. Reddy provided evidence that CHH mediates cadmium-induced hyperglycemia in the red swamp crayfish, Procambarus clarkii. In a study of another hormonally-regulated function, color changes, cadmium exposure resulted in pigment in the melanophores of the fiddler crab, Uca pugilator, becoming less dispersed than in unexposed crabs. Earlier studies showed that, like cadmium, bothmore »« less

Effects of sublethal exposure to lead on levels of energetic compounds in Procambarus clarkii (Girard, 1852)

Journal Article Martinez, M ; Torreblanca, A ; Del Ramo, J ; ... - Bulletin of Environmental Contamination and Toxicology; (United States)

Lead is neither essential nor beneficial to living organisms; all existing data show that its metabolic effects are adverse. Lead is toxic to all phyla of aquatic biota. Most of the lead discharged into surface water is rapidly incorporated into suspended and bottom sediments. The American red crayfish, Procambarus clarkii, lives in a wide range of environmental conditions that include highly polluted waters. Lead present in take sediments can be available to aquatic animals such as P. clarkii because it is a detritivor and burrow into the sediment. In fact, we found remarkable levels of lead in tissues of P.more »« less
