Abstract

The hydrogen ion is an important determinant of toxicity in the aquatic environment, especially for weak acids or bases. Pentachlorophenol is a weak acid and is consequently more toxic at low pH because of increasing proportions of free phenol. For some heavy metals the toxic interaction with ambient pH is complicated by complexation with organic and inorganic compounds. These complexes are affected by pH, and bioassays may be the easiest and most reliable method of determining the influence of pH in such cases. The objective of this study was to find a simple laboratory procedure for determination of the effect of pH on the toxicity of various chemicals added to or already present in various samples of ground and surface waters. Pentachlorophenol was selected as a reference toxicant and positive control because of its established pH-toxicity interaction in fish.

Modulation of cupric ion activity by pH and fulvic acid as determinants of toxicity in Xenopus laevis embryos and larvae

Journal Article Buchwalter, D; Linder, G; Curtis, L - Environmental Toxicology and Chemistry

An ion-specific electrode measured cupric ion activity modulated by fulvic acid (FA) and pH in a series of modified Frog Embryo Teratogenesis Assay--Xenopus (FETAX) toxicity assays. Hydrogen ion concentration was the primary determinant of cupric ion activity, while FA played a smaller but significant role. Fulvic acid was a weak copper complexing agent at pH 5.50. At pH 5.50 there was slight reduction of ionic activity and a subsequent attenuation of copper toxicity with 5.0 mg/L FA. At pH 7.50, FA also had a mild attenuating effect on copper toxicity. At pH 6.50, copper was strongly complexed by FA atmore »« less

Effect of intermittent chlorination on developing zebrafish embryos (Brachydanio rerio)

Journal Article Yosha, S; Cohen, G - Bull. Environ. Contam. Toxicol.; (United States)

The primary objective of this study is to determine whether chlorine adversely affects the hatchability of freshwater fish embryos and to what extent, if any, chlorine toxicity is modified by the ionic composition of the water.

Toxicity to embryo and adult zebrafish of copper complexes with two malonic acids as models for dissolved organic matter

Journal Article Palmer, F; Evans, C; Butler, C; ... - Environmental Toxicology and Chemistry

The toxicity to embryo and adult zebrafish (Danio rerio) of Cu complexes with two substituted malonic acids, benzyl- and n-hexadecyl-, chosen as models for low-molecular-weight natural dissolved organic matter, were investigated. Toxicity test solutions at pH 6.5 {+-} 0.1 with the required Cu ion-specific electrode. In the absence of malonic acids, concentrations of Cu{sup 2+} up to 1.13 {mu}mol/L increased the embryo hatching time from approx. 2 d in control solutions (no Cu or malonic acid) and solutions containing malonic acids without Cu to approx. 8 d. The Cu-benzylmalonic acid complex in the presence of inorganic Cu species did notmore »« less

Acute lethal toxicity of some reference chemicals to freshwater fishes of Scandinavia

Journal Article Oikari, A - Bull. Environ. Contam. Toxicol.; (United States)

Relevance of the choice of a test organism intended to be representative for a given environment seems to be under continual debate in aquatic ecotoxicology. For instance, it is commonly argue that acute toxicity tests with rainbow trout, the species most often recommended as a standard cold water teleost, were not representative for Nordic countries because the species is an alien in local faunas. A comparative study with several freshwater species was therefore initiated to clarify the validity of this assumption. As a first approximation, standard LC 50 assays were conducted. The species used were chosen only on the basismore »« less

Influence of pH on the toxic effects of zinc, cadmium, and pentachlorophenol on pure cultures of soil microorganisms

Journal Article Beelen, P; Fleuren-Kemilae, A - Environmental Toxicology and Chemistry

In this study the effect of acidification of soil pore water on the uptake and toxicity of cationic and anionic pollutants was measured in an experimental model system. The influence of pH on the toxic effects of zinc, cadmium, and pentachlorophenol was studied in buffered suspensions of pure cultures of soil microorganisms. In this system the speciation of the toxicant, the pH, and the biomass are defined, constant, and thus easier to study than in a system with the solid soil matrix and pore water. The mineralization of [{sup 14}C]acetate to {sup 14}CO{sub 2} was used to measure the toxicmore »« less
