This review addresses an important area of environmental and mammalian toxicology by evaluating and comparing mercury-induced effects upon the immune responses of two evolutionarily divergent yet immunologically-related species. The mechanisms of mercury toxicology and immunotoxicology are described herein, including supporting data from the following: sources of exposure; bioavailability and biodistribution; metabolism; and laboratory and field investigations. Based upon the studies presented, the relative sensitivities of fish and human immune cells to mercury exposure are compared and contrasted with regard to mercury's ability to stimulate and/or suppress host immunocompetence. In addition, results from immune assays are compared to mercury tissue burdens, as well as to toxicological threshold level estimates. Such comparisons may help to resolve gaps in our knowledge regarding sensitivity of immunological assays, standardization of immunotoxicological techniques between species, and the extent to which the vertebrate immune system possesses functional reserve and redundancy in response to xenobiotics. A review of this type begins to provide support for the potential usefulness of fish immune cells to serve as indicators for human immunotoxicology risk assessment. Analysis of the reviewed studies supports the following conclusions in both lower and higher vertebrates: a threshold for mercury-induced immunotoxicological effects is likely; multiple exposure scenarios involving high and/or chronic exposures leading to increased body burdens are linked to increased risk of immunomodulation; and highly exposed and/or susceptible subpopulations are at greater risk of toxicological impact.

“…Similarly localized pollutants can then take a toll disproportionate to their effects should both pollutants and fish be dispersed throughout the baydelta system. Fish aggregated in zones of preferred temperatures are often performing physiologically at high rates, a condition that can accelerate bioaccumulation and toxicity of pollutants (Reinert et al 1974). Dissolved oxygen can be depleted in zones of cool water needed by fish.…”

Thermal preference: when does an asset become a liability?

SynopsisMost fish species (and sometimes different life stages within a species) exhibit behavioral temperature selection. In nature, thermal gradients provide habitat structure to which fish orient. Apparently, fish have evolved to fit into 'thermal niches' to optimize physiological, ecological, and reproductive performance in their native habitats. However, man has perturbed many of these habitats to the point where previously advantageous thermal preference behavior may now be inappropriate. Thermal perturbations are the most obviously related examples of man's interference, but a fish's inherent thermal preference behavior can also magnify the biological effects of changes in dissolved oxygen, food supply. toxicants, and physical barriers. Environmental management should (1) consider thermal preference behavior when evaluating habitat suitability, (2) manage for needed temperature and thermal structure, and (3) give priority attention to minimizing degradation of preferred thermal habitat, especially when it is in short supply.

“…Black et al [6] showed that temperature change had a proportional effect on the uptake of oxygen and the three toxicants, benzo[ a ]pyrene, tetrachlorobiphenyl, and naphthalene, by fish gills. Accumulation of DDT by rainbow trout was increased by 45% between 5 and 15°C [43]. Accumulation of DDT by mosquito fish ( Gambusia holbrooki ) was three times greater at 20°C than at 5°C [44].…”

The ventilation amplitude and frequency of silver perch Bidyanus bidyanus, and the ventilation frequency of rainbow fish Melanotaenia duboulayi and rainbow trout Oncorhynchus mykiss, were determined at different temperatures upon exposure to endosulfan and chlorpyrifos, respectively. Silver perch and rainbow fish were tested at 15, 20, 25, 30, and 35 degrees C, while rainbow trout was tested at 10, 15, 20, and 25 degrees C. Although some trend of increasing amplitudes with increasing temperature was evident; there was no significant temperature response of ventilation frequency rates over time in silver perch pre-exposed to 10 microg L(-1) endosulfan for 18 h. The rate of ventilation frequency of rainbow fish pre-exposed to 200 microg L(-1) of chlorpyrifos for 96 h was lower in treatments than in the control at 15 degrees C. However, between 20 and 35 degrees C, rates were significantly higher in the treatments than those of the control. In rainbow trout pre-exposed to 100 microg L(-1) of chlorpyrifos, the rates of frequency were significantly lower than those of controls in temperatures between 10 and 20 degrees C but higher at 25 degrees C. The amplitude of silver perch seemed to increase with the increase in temperature; however, the corresponding temperature quotient values at various temperature regimes and over exposure time showed no significant differences. The ventilation frequency of rainbow fish and rainbow trout significantly increased at the higher test temperatures, and their corresponding temperature quotient values for both fish also increased at the elevated temperatures.
