✦ Synopsis

We have designed a laboratory bioassay to expose fish to kinetically determined differences in aluminium hydroxide solution chemistry. We have used this system to demonstrate the hitherto unexpected result of an acute aluminium toxicity in the fish at a pH of 6.5. Supporting experiments have demonstrated that the mechanism of toxicity at this pH was probably an asphyxiation brought about by aluminium-induced changes in the rheological and diffusional properties of the mucus lining of the gill epithelium.

## Abstract The polycyclic aromatic hydrocarbons (PAHs) phenanthrene and retene (7‐isopropyl‐1‐methyl phenanthrene) are lethal to rainbow trout __(Oncorhynchus mykiss)__ larvae during chronic exposures. Phenanthrene is a low‐toxicity, non‐cytochrome P4501A (CYP1A)—inducing compound that accumulates
