Physiological endpoints in daphnid acute toxicity tests

Science of The Total Environment, 2020
Daphnids are freshwater crustaceans used in toxicity tests. Although lethality and immobilisation are the most commonly used endpoints in those tests, more sensitive parameters are required for determination of sublethal acute effects of toxicants. The use of various physiological endpoints in daphnids is considered as a low-cost and simple alternative

A comparison of standard acute toxicity tests with rapid-screening toxicity tests

Environmental Toxicology and Chemistry, 1995
AbstractThis study compared the relative sensitivity of five inexpensive, rapid toxicity tests to the sensitivity of five standard aquatic acute toxicity tests through literature review and testing. The rapid toxicity tests utilized organisms that require little culturing or handling prior to testing: a freshwater rotifer (Branchionus calyciflorus ...

Acute Toxicity of a Tire Rubber-Derived Chemical, 6PPD Quinone, to Freshwater Fish and Crustacean Species

Environmental Science and Technology Letters, 2021
N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine-quinone, also known as 6PPD quinone, was recently identified as a toxic chemical that causes acute mortality in coho salmon following exposure to urban runoff.

Zebrafish larvae acute toxicity test: A promising alternative to the fish acute toxicity test

Aquatic Toxicology, 2022
Aquatic toxicity is a mandatory component in risk assessment of chemicals. The currently recommended used acute fish toxicity (AFT) test requires a large test system, bringing onerous experimental operation and discharge of much experimental wastewater.

Fish embryo tests and acute fish toxicity tests are interchangeable in the application of the threshold approach

Environmental Toxicology and Chemistry, 2019
A database was compiled for algal Organisation for Economic Co‐operation and Development (OECD) test guideline 201, for Daphnia magna OECD test guideline 202, for the acute fish toxicity (AFT) OECD test guideline 203, and for the fish embryo toxicity ...

Predictive Acute Toxicity Tests With Pesticides.

Acta Pharmacologica et Toxicologica, 1983
Abstract By definition pesticides are biocidal products and this implies a probability that pesticides may be acutely toxic to species other than the designated target species.The ways in which pesticides are manufactured, formulated, packaged, distributed and used necessitates a potential for the exposure of non‐target species although the technology ...

Non-animal Replacements for Acute Toxicity Testing

Alternatives to Laboratory Animals, 2015
Current approaches to predicting adverse effects in humans from acute toxic exposure to cosmetic ingredients still heavily necessitate the use of animals under EU legislation, particularly in the context of the REACH system, when cosmetic ingredients are also destined for use in other industries.

Acute and chronic toxicity of acetamiprid, carbaryl, cypermethrin and deltamethrin to Apis mellifera larvae reared in vitro.

Pest Management Science, 2020
BACKGROUND The effects of exposing Apis mellifera larvae to common insecticides were tested in the laboratory. RESULTS The acute toxicity values of the four insecticides that we tested ranged from high toxicity to low toxicity: deltamethrin ...

Hazard evaluation of polystyrene nanoplastic with nine bioassays did not show particle-specific acute toxicity.

Science of the Total Environment, 2019
Plastic is a wide-spread pollutant and must be evaluated for potential adverse effects of its breakdown product, microplastic (≤5 mm) along with its subfraction, nanoplastic (1-100 nm).
