RESUMO O presente trabalho teve como objetivo estudar a influência das variáveis físico-
químicas tais como pH, dureza total e alcalinidade total da água, na toxicidade do zinco …

Acute static tests were performed to assess Zn toxicity on adults of Cnesterodon
decemmaculatus (not sexed), a neotropical fish of wide distribution in the Río de la Plata …

Four-day tests of the toxicity of zinc sulfate to minnows were made at 3 pH levels (6, 7 and 8)
and 3 total hardness levels (50, 100 and 200 ppm as CaCO3). Continuous-flow tests were …

Four species of salmonids were exposed to different dilutions of water from a stream
polluted by zinc. Test duration was 14 days for all species. The TL 50 for rainbow trout …

The background concentrations of Zn in aquatic environments are comparatively low. In
unpolluted areas, the concentrations of total Zn in the water have been reported to be 1| ig I" …

Zinc is used in several industries and is also a ubiquitous water pollutant discharged into
aquatic reservoirs. Its acute and chronic toxicity to fishes has been intensively studied …

The acute and chronic toxicity of zinc to wild mottled sculpin (Cottus bairdi) was measured
with 13‐d and 30‐d flow‐through toxicity tests, respectively. Exposure water hardness was …

Daphnia magna and Brachydanio rerio are important test organisms in toxicity tests. The
bioaccumulation of zinc in these species was investigated in two semistatic experiments in …

The aim of this study was to evaluate the effect of zinc sulfate (ZnSO4) on hematological
parameters of bullfrog tadpoles, Lithobates catesbeianus, through acute and chronic toxicity …
