Due to the high insolubility of the ZrC in
water, aquatic toxicity is considered unlikely to occur. Hence,
conducting aqautic toxicity studies with daphnia, algea and activated
sludge is scientifically not necessary.
This is supported by available acute
toxicity data on fish: ZrC did not cause mortality in Danio rerio when
introduced in test aquaria at a nominal concentration of 100 mg/L (daily
renewal of test solution, total exposure duration: 96 h).
