The impacts of pH and dissolved organic carbon (DOC) on the acute toxicity of Cu to larval fathead minnow (Pimephales promelas) were determined using natural soft water from two Precambrian Shield lakes in south-central Ontario. By artificially manip

Fish in low-alkalinity lakes having pH of 6.0-6.5 or less often have higher body or tissue burdens of mercury, cadmium, and lead than do fish in nearby lakes with higher pH. The greater bioaccumulation of these metals in such waters seems to result p

Rainbow trout (Salmo gairdneri) exposed to lead in Lake Ontario water demonstrated a 21-day LC50 of 2.4 mg l−1 lead. At lead concentrations ranging from 3 to 120 μg l−1, log10 of lead concentrations in most tissues of exposed fish appeared linea

1. Rainbow trout exposed to waterborne zinc at an acutely lethal level (1.5 mg/l) or at a lower concentration close to the 4 d LC50 (0.8 mg/l) exhibited contrasting physiological responses in artificial soft water (ASW). 2. The changes in acid-base s

The activity of erythrocyte δ-amino levulinic acid dehydratase (ALA-D) of fish is easily measured under a variety of experimental conditions. Exposure of rainbow trout (Salmo gairdneri), brook trout (Salvelinus fontinalis), goldfish (Carassius aurat

Exposure to 0.8 mg Zn2+/L in natural soft water for up to 72 h was toxic to rainbow trout, Salmo gairdneri, causing an acid–base disturbance and net branchial ion losses. Mean arterial pH fell from 7.78 to 7.58. Both [Formula: see text] and lactate

At a waterborne [Zn] of 1.9 mg∙L−1in hard water (~1 mmol Ca∙L−1), Zn influx across an isolated, saline-perfused head preparation of rainbow trout (Salmo gairdneri) was about 1.5 nmol∙kg−1∙h−1through the lamellar pathway and about 1 nm

Chlorine can be removed from laboratory water supplies by reduction with sodium sulfite, but sulfite complexation of metals may bias aquatic toxicity tests. We tested the effect of waterborne sulfite on the accumulation of waterborne lead by rainbow

Rainbow trout, Salmo gairdneri, were fed purified diets with zinc concentrations ranging from deficient to excessive (1, 90, 590 μg Zn∙g−1) and simultaneously exposed to a range of waterborne [Zn] (7, 39, 148, 529 μg Zn∙L−1). After 1 wk, fi
