Environmental Toxicology, EarlyView.ABSTRACT Diflubenzuron is used as an insect growth inhibitor, and its potential risk to human health was raised owing to the possibility of environmental residues and human exposure. This study aimed to investigate the toxic mechanism of diflubenzuron on trophoblastic cells such as HTR8/SVneo and JEG‐3 cells. We investigated mitochondrial function, Ca2+

Environmental Toxicology, EarlyView.ABSTRACT Tartrazine (TZ) is a widely used synthetic azo dye with high aqueous stability, resulting in persistence in wastewater. Photoreactive nanomaterials, principally zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs), are frequently employed for dye removal under light‐exposed conditions; nevertheless, their ecotoxicological ...

Estimation of LC50 and its confidence interval for the effect of ferrous sulphate on Catla catla [PDF]
, 2018 Probit analysis is generally employed in the studies of toxicology, to determine the concentration of toxicant causing 50% mortality or LC50 value. The response of an organism is generally binomial and is typically sigmoidal in property. The Probit value

DETERMINATION OF ACUTE TOXICITY OF COPPER AND COBALT FOR TILAPIA NILOTICA
Journal of Bioresource Management, 2015 During the present investigation, the 96-hr LC50 and lethal concentrations of copper and cobalt for Tilapia nilotica were determined under controlled laboratory conditions at constant pH (7.25), total hardness (255 mgL-1) and temperature (30 °C). During

Environmental Toxicology, EarlyView.ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...
