The literature identified that juveniles and small individuals are most susceptible to fluoride. An increase in temperature as well as a decrease in water hardness increases the acute toxicity of fluoride.

TOXICITY OF ZINC COMPOUNDS TO AQUATIC ANIMALS, WITH SPECIAL REFERENCE TO FISH BY J. SKIDMORE Department of Zoology, Australian National University, Canberra, Australia ABSTRACT The toxicity of zinc compounds to aquatic animals is modified by several environ-mental factors, particularly the hardness of the dilution water, the dissolved oxygen.
We investigated the influence of acclimation on results of in situ bioassays with cutthroat trout in metal-contaminated streams. Effects of acclimation on the toxicity of stream water contaminated with zinc and cadmium to juvenile cutthroat trout.
