“…Changes in oxygen consumption rate are a good index to measure altered metabolic activity Effect of lead nitrate on oxygen consumption of fresh water prawn Environment Conservation Journal (12) in organism exposed to various toxicants in surrounding medium. Continuous decrease in oxygen consumption, as observed in present study has also been reported in various crustaceans (Chinnaya, 1971;Ghate and Mulhelker, 1979;Tulasi and Rao, 1989;Papathanasiou and King, 1983;Reddy and Venugopal, 1993;Chinni et al, 2000;Jadhav and Ambore, 2007;Sen et al, 2008).

“…Mitochondrial damage and reduction in ability to synthesize the ATP in gills as reported in Palaemon serratus (Papathanasiou and King, 1983) after exposure of cadmium may also be a reason for reduced oxygen consumption in M. dayanum after lead exposure. Almost similar findings have been reported by Tulasi and Rao (1989) on oxygen equilibrium curve of the freshwater field crab, Barytelphusa guerini after organic and inorganic lead exposure. Recently, Sen et al (2008) reported almost similar findings in M. dayanum after cadmium chloride exposure.…”

“…Lead is considered as a non-specific poison affecting physiological systems and can cause brain damage, kidney damage, gastrointestinal distress and reproductive disorders (Campana et al, 2003;Kutlu and Summer, 1998). Toxic effect of lead and other heavy metals on opercular beat and oxygen consumption has been mostly investigated in fishes (Hiltbran, 1971;Singh and Singh, 1979;Rao and Ramamurthi, 1987;Gill et al, 1988) but crustaceans despite being important member of food chain and having high economic and medicinal value ar e being documented less in reference to metal toxicity and oxygen consumption (Chinnaya, 1971;Ghate and Mulhelker, 1979;Papathanasiou and King, 1983;Tulasi and Rao, 1989;Reddy and Venugopal, 1993;Chinni et al, 2000;Jadhav and Ambore, 2007;Sen et al, 2008). Considering the above facts, present work has been taken into account to evaluate toxic effects of lead nitrate on oxygen consumption of freshwater prawn, Macrobrachium dayanum (Crustacea-Decapoda), a potential animal for fresh water aquaculture.…”

Freshwater prawn, Macrobrachium dayanum were subjected to acute concentration, 116.46 mg/l (96 hr LC50 value) and sub-acute concentration, 29.12 mg/l (25% of 96 hr LC50 value) of lead nitrate to evaluate its effects on oxygen consumption. Initial increase in oxygen consumption was noticed which was followed by gradual decrease up to 96 hr in acute exposure while significant (F = 20.33; P < 0.001) decrease in oxygen consumption was noticed through out the experiment during sub-acute exposure up to 30 days. Mechanism of lead intoxication and potential of oxygen consumption as bio-marker has been discussed.

Energy metabolism of aquatic invertebrates is one of the most important targets of environmental pollutants, in particular, heavy metals. In this study, we determined changes in survival, oxygen uptake and hepato-pancreas glycogen level of the bivalve mollusk I Into tumidus Philipsson following chronic exposure of Cd and Zn salts (chlorides and sulfates). The concentrations of Cd salts were equal to 0.001, 0.01 and 0.1 mg/1 and concentrations ofZn salts were equal to 0.01, 0.1, 1.0 mg/1 (maximal contamination level for Cd is 0.005 mg/1 and for Zn is 0.01 mg/1). Survival was registered daily whereas oxygen consumption and glycogen level were determined on days 3, 7 and 14. Changes in survival of U. tumidus along the course of Cd and Zn salt concentrations was not monotonic; the sulfates were more inhibitory than the chlorides. No correlation was found between changes in survival and changes in the oxygen uptake and the glycogen level. By analysis of data in the literature, it was possible to construct a general scheme of adaptation of aquatic invertebrates' energy metabolism to heavy metals impact: (1) "exhaustive" or "economical" activation of aerobic metabolism (with or without depletion of energy resources);(2) change to "exhaustive" anaerobic mechanism (with depletion of glycogen); (3) change to "economical" anaerobic metabolism (involving mechanisms of glycogen expenditure economy); (4) late-term activation of aerobic metabolism due to need for binding and excretion of accumulated metals. Different severity of the pollutants' impact may lead to prevalence of different stages of this scheme. Our results revealed most of these stages in U. tumidus·. "economical" activation of aerobic metabolism, change to "exhaustive" and "economical" anaerobic metabolism, and late-term activation of aerobic metabolism.It can be suggested that Cd is more toxic due to late-term decrease in oxygen consumption whereas Zn resulted only in transient early-term decrease. On the other hand, mechanisms of glycogen economy during anaerobic metabolism were involved in the effect of Cd and not involved in the effect of Zn. Concerning the effect of anions, chlorides promoted transient activation of aerobic metabolism, while sulfates promoted the passage to anaerobic metabolism. Thus, the effect of sulfates seems to be more inhibitory than the effect of chlorides.
