Estimation of the LC50, a review

Environmetrics, 1991
AbstractIn this paper methods to estimate the median lethal concentration (LC50) are reviewed. Estimation from data sets with limited occurrence of partial response (>0%, <100%) receives particular attention.

Determination of LC50 and sub-chronic neurotoxicity of diesel exhaust nanoparticles

Environmental Toxicology and Pharmacology, 2015
Air pollution is a major problem faced globally and is seen associated with central nervous system (CNS) disorders like neuropathology and neuro-inflammation. Here, we investigated the CNS disorders as a result of sub-chronic exposure (90 days) to diesel exhaust nanoparticles (DENPs) and explored the minimal levels of DENPs needed to exhibit the early ...

LC50 of lambda-cyhalothrin stimulates reproduction on the moth Mythimna separata (Walker)

Pesticide Biochemistry and Physiology, 2019
Lambda-cyhalothrin has long been recommended as an effective insecticide to control the oriental armyworm, Mythimna separata (Walker), a notorious migratory pest of agricultural plants. Previous researches have suggested that survival, development, and reproduction of insects are influenced by sublethal concentrations of insecticides.

Comparing LD50/LC50 Machine Learning Models for Multiple Species

Journal of Chemical Health and Safety, 2023
The lethal dose or concentration which kills 50% of the animals (LD50 or LC50) is an important parameter for scientists to understand the toxicity of chemicals in different scenarios that can be used to make go-no-go decisions, and ultimately assist in ...

Genotoxic Effects and LC50 Value of NaOCl on Orthrias angorae (Steindachner 1897)

Bulletin of Environmental Contamination and Toxicology, 2008
Studies show that different organisms used as bio-indicators have indicated several genotoxic and mutagenic effects of disinfected waters. In this study, the 96 h LC(50 )mean value of NaOCl for Orthrias angorae was calculated to be 0.5509 mg/L. The results showed that NaOCl is highly toxic to O. angorae specimens.
