The science of risk assessment revolves broadly around hazard identification (toxicity) and exposure assessment information. While exposure to environmental hazards most often occurs with complex chemical mixtures, the majority of existing toxicity data is for single compounds or simple mixtures, thus presenting problems to the risk assessor. Several approaches to assess mixtures have been deve...

The Guidance Manual for the Assessment of Joint Toxic Action of Chemical Mixtures (Mixtures Guidance Manual) is intended to assist environmental health scientists and toxicologists in determining whether exposure to chemical mixtures at hazardous waste sites may affect public health. The Agency for Toxic Substances and Disease Registry (ATSDR) approach is a semi-quantitative screening process. ...

background: the use of chemicals is essential in education resulting in exposure to these pollutant in a variety of chemical and research laboratories. chemical contaminants in chemical laboratories are in different forms and chemical exposure risk assessment is important for choosing appropriate controls in protecting the health of operators, experts and students. for risk assessment in chemic...

Heavy metals are normally occurring elements that have a density at least 5 times higher than of water. Their plentiful domestic, industrial, agricultural and technological usages have led to their widespread distribution in the environment; raising worries over their possible impacts on human health and the environment. The toxicity of heavy metals relies on numerous factors including the dose...

Abstract The lithium–sulfur battery is considered to be one of the most promising rechargeable energy storage systems because its high theoretical density. Unfortunately, shuttle effect during cycling causes serious loss sulfur species and corrosion lithium metal anode, resulting in severe capacity decay. This work proposes completely suppress polysulfides (LiPSs) without sacrificing interfacia...
