Metals are essential elements for human life but may cause disorders when exposure is
excessive. Previously, we reported on the acute toxicity of 50 metals; however, the chronic …

Metals are essential for human life and physiological functions but may sometimes cause
disorders. Therefore, we conducted acute toxicity testing of 50 metals in Daphnia magna …

The speciation and bioavailability of metals are known to be affected by pH. Although many
studies have focused on effects on metals of pH changes resulting from lake acidification (ie …

The relatively low availability of toxicity data for indigenous tropical species has often been
discussed. In addition, several taxonomic groups of invertebrates are understudied, such as …

Abstract The toxicity of Hg 2+[HgCl 2], Cr 6+(1)[(NH 4) 2 CrO 4], Cr 6+(2)[CrO 3], Cd 2+[CdCl
2· 2, 5H 2 O], Pb 2+[Pb (CH 3 COO) 2· 3H 2 O], and As 5+[Na 2 HAsO 4· 7H 2 O] on the …

Previous research done on the effects of contaminant mixtures has been evaluated primarily
by using acute exposures. While this was an important initial step, characterizing the effects …

A study was conducted to determine the median lethal toxicity of four heavy metals on the
marine gastropod Babylonia areolata. Median lethal toxicity tests were conducted to observe …

We examined the acute toxicity of 14 different kinds of metals affecting medaka fry and from
the results, arranged them according to the order of intensity level of acute toxicity. The most …

The toxicity of mixtures of copper, zinc, and diazinon were determined for Ceriodaphnia
dubia using 7‐d survival and reproduction tests. Fifteen treatments, including combinations …

Acute and chronic bioassays were conducted to determine the effects of copper, lead, and
zinc mixtures on Ceriodaphnia dubia and Daphnia carinata. Copper, lead, and zinc …
