“…Therefore, when choosing an appropriate organism for use in bioassays which measure energetic responses, background information on its physiology and biochemistry is essential. In utilizing these biochemicals to assess the effects of stressors, it must be remembered that many factors including species, sex, season, temperature and hormonal status can affect the basal concentrations of energy substrates (Chavin & Young, 1970;Thorpe & Ince, 1974;Plisetskaya, 1980;Fletcher, 1984;Lehtinen et al, 1984).…”

“…Chronic exposure of Channa punctatus to chromium caused hypoglycemia, while glycogen concentrations increased in liver but decreased in muscle tissue of C. punctatus (Sastry & Sunita, 1983). Rainbow trout exposed to an effluent containing 260 mg Ti/l in an effluent had elevated plasma glucose and lactate concentrations when exposed at 13-15 C, however, these effects were not observed when the fish were exposed at 7-8 °C (Lehtinen et al, 1984). The results of that study indicate some of the problems that may be encountered in interpreting the results of energetic and metabolic indicators of toxicant-induced stress in fish.…”

The ultimate goal of toxicity testing is to monitor or predict the effects of single compounds, elements or mixtures on the long-term health of individual organisms, populations, communities and ecosystems. Unfortunately, one does not always have all of the information required to determine the long-term or 'chronic' effects of toxicants on the survival, growth or reproduction of aquatic organisms. For this reason, the chronic effects of toxicants are often inferred or estimated from observations made during short-term or 'acute' field or laboratory studies, which may be conducted at greater concentrations of toxicant. The observations made in the short-term studies are then related to the chronic effects by some statistical relationship. There are basically two approaches: 1)The long-term effects on a parameter, such as survival (lethality) are predicted from observations on the same parameter, during short-term exposures; 2) Alternatively, the response of one parameter to long-term exposures of a toxicant can be predicted from the short-term responses of a different parameter. In this report we present several different examples of both types of methods for estimating chronic responses from information on more short-term responses and discuss the rationale, advantages and disadvantages of each. We also report on two biochemical indicators; energetic substrates and RNA/DNA ratio. These indicators both act as sensitive, integrative measures of sublethal effects of contaminants during both acute and chronic exposures.

“…Other adverse effects included a lack of striated border in the gut lumen, and the destruction of kidney tubules (Sunila 1986). Rainbow trout exposed to supernatant waste developed general stress symptoms at 13-15 8C, and plasma hypocalcemia and sexdependent inhibition of erythrocytic deltaaminolevulinic acid dehydratase (ALAD) enzyme activity at 7 -8 8C (Lehtinen et al 1984).…”

“…There is little published information concerning the environmental toxicity of TiPRs. Previous studies of the environmental toxicity of Ti mineral‐processing by‐products have generally focused on the environmental impacts of Ti industry liquid‐effluent discharges to water bodies, including reports of physiological disturbances to rainbow trout and changes to benthic invertebrate community structure as a result of Ti‐processing effluent discharge. As early as 1973, concerns were raised about the disposal of solid TiPRs in the Mediterranean Sea ; however, the toxicity of solid TiPRs to marine organisms was not reported at that time.…”

Thorough examination of the physicochemical characteristics of a Ti-processing residue was undertaken, including mineralogical, geochemical, and radiochemical characterization, and an investigation of the environmental toxicity of soft-water leachate generated from the residue. Concentrations of most metals measured in the leachate were low; thus, the residue is unlikely to leach high levels of potentially toxic elements on exposure to low-ionic strength natural waters. Relative to stringent ecosystem health-based guidelines, only chromium concentrations in the leachate exceeded guideline concentrations for 95% species protection; however, sulfate was present at concentrations known to cause toxicity. It is likely that the high concentration of calcium and extreme water hardness of the leachate reduced the bioavailability of some elements. Geochemical modeling of the leachate indicated that calcium and sulfate concentrations were largely controlled by gypsum mineral dissolution. The leachate was not toxic to the microalga Chlorella sp., the cladoceran Ceriodaphnia dubia, or the estuarine bacterium Vibrio fischeri. The Ti-processing residue exhibited an absorbed dose rate of 186 nGy/h, equivalent to an annual dose of 1.63 mGy and an annual effective dose of 0.326 mGy. In summary, the results indicate that the Ti-processing residue examined is suitable for productive use as an environmental amendment following 10 to 100 times dilution to ameliorate potential toxic effects due to chromium or sulfate.
