Lead (Pb)Heavy metalsCatalase enzymeFatty acidsHeavy metal pollution is becoming a worldwide problem affecting pollinators. The massive use of lead (Pb), the most harmful metal for the biosphere, in industries has increased the risk for honey bees. Pb exerts toxicity on living organisms inducing...

The hypothesis that excess dietary selenite ameliorates lead (Pb) toxicosis in domestic sheep was tested. Twenty 6–8-yr-old ewes fed alfalfa pellets were assigned to the following treatments: (1) control; (2) 9.8 mg Pb/kg body weight (b.w.)/d as PbCO 3 ; (3) 3 mg Se/animal/d...
and accumulation mechanisms of Pb and its toxic effects on germination, growth, yield, nutrient relation, photosynthesis, respiration, oxidative damage, and antioxidant defense system of rice. Lead toxicity hampers rice germination, root/shoot length, growth, and final yield. It reduces nutrient uptake...
The use of integrative molecular approaches can aid in a comprehensive understanding of the effects of toxicants at different levels of biological organization, also supporting risk assessment. The present study aims to unravel the toxicity mechanisms of
Abstract Lead (Pb), a ubiquitous and potent neurotoxicant, induces several neurophysiological and behavioural changes, while Pb alters the function of multiple organs and systems, it primarily affects the central nervous system. In human adults, encephalopathy resulting from Pb intoxication is often cha...
(SOD) activity under 50 and 100 mg/L TWP exposure predicted a substantial activation of oxidative stress. In contrast, the significant increase in the malondialdehyde (MDA) content indicated the overproduction of reactive oxygen species (ROS) and may lead to lipid peroxidation damage. These ...
UFCB mainly come from the processing industries such as tires and inks, as well as the emission of vehicle exhausts [8]. It thus appears that people's exposure to UFCB mainly involves occupational contact and inhalation in life. At present, nanotoxicology studies on the toxicity of UFCB are...
Arsenic is a hazardous environmental contaminant, which is considered as a king of poisons. It is ranked at the top in the list of hazardous substances by Agency for Toxic Substances and Disease Registry (ATSDR) on the basis of the extent of toxicity, prevalence and exposure to humans1. Arse...
