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 ...

Strategic hierarchical approaches to acute toxicity testing

Toxicology in Vitro, 1994
Acute toxicity testing, including testing for irritation and sensitization, traditionally has relied heavily on animal models. While this situation has not yet changed dramatically, new developments and approaches offer opportunities to minimize or ultimately to eliminate altogether the use of animals in specific areas of acute toxicity. The value of a

Acute Aquatic Toxicity and Biodegradability of Fluorinated Ionic Liquids

ACS Sustainable Chemistry and Engineering, 2019
Several novel fluorinated ionic liquids (FILs), fully miscible with water and with excellent surfactant behavior, have been studied for pharmacological applications.

Mixture Toxicity Indices in acute lethal toxicity tests

Archives of Environmental Contamination and Toxicology, 1987
The use of Mixture Toxicity Indices (MTI's) is one of the more attractive approaches for describing and predicting the effects of mixtures of toxicants. For an MTI to apply to all possible mixtures of the compounds in question, it must summarize information from a model describing all possible responses of interest.
