“…Cadmium and lead at elevated levels are always toxic (Crespo et al 1986). The availability of these elements varies according to a number of environmental factors (Zitko and Carson 1977;Chakoumakos, Russo, and Thurston 1979) and as a result of diet (Hardy and Shearer 1985). Many endogenous factors strongly in uence metal kinetics and effects (Foulkes 1995).…”

The cadmium, lead, copper, and zinc levels were measured in six organs (lung, liver, kidney, skin, muscle, and bone) from 18 specimens of toothed whales, belonging to five species, found stranded along the Corsican coast between November 1993 and December 1998. The five species examined were the bottlenose dolphin Tursiops truncatus, the common dolphin Delphinus delphis, the striped dolphin Stenella coeruleoalba, the pilot whale Globicephala melas, and the Risso's dolphin Grampus griseus. The values obtained demonstrate that there is a great variability in the accumulation of toxic metals. A comparison of the values with those obtained in other geographical regions also demonstrates an extensive variability in metal levels. The presence of metals in the stomach contents of three of the individuals studied shows that the food source is responsible for a significant input of pollutants to the whales. Measured pollutant levels in whales are thus the result of an accumulation occurring throughout the animal's life.

“…For example the incipient lethal level to juvenile Atlantic salmon inhabiting the Miramichi River (Canada) varied seasonally from 0.15 to 1.10 mg L-I (Figure 9-3). The most sensitive period occurred between March and August, a reflection of developmental stage of the fish and environmental conditions (Zitko and Carson, 1977). Based on laboratory experiments acute toxicity of zinc may also depend on acclimation temperature ( Figure 9 -4).…”

“…Zitko and Carson (1977) found the ILL of zinc to juvenile Atlantic salmon varied from 0.15 to 1.0 mg/liter from fall through spring, with no detectable seasonal changes in water hardness, alkalinity, dissolved nitrogen, and humic acid concentration. The most sensitive period, as measured by the zinc ILL, coincided with the initial stages of the parr-smolt transformation and was, therefore, believed to be related to this physiological change.…”

Methods of mining and the effects on aquatic ecosystems of mine-caused sediment, changes in pH, and toxic heavy metals are described. KEYWORDS PREFACEThis is one of a series of publications summarizing knowledge about the influences of forest and rangeland management on anadromous fish habitat in Western North America. This paper addresses the effects of mining on anadromous fish habitat. Our intent is to provide managers and users of the forests and rangelands of Western North America with the most complete information available for estimating the consequences of various management alternatives.In this series of papers, we summarize published and unpublished reports and data as well as observations of resource scientists and managers. These Lcompilations should be valuable to resource managers in planning uses of forest and rangeland resources, and to scientists in planning future research. The extensive lists of references serve as a bibliography on forest and rangeland resources and their uses.Previous publications in this series include:1. "Habitat requirements of anadromous salmonids,'t
