Chemical-by-chemical bans leave people at risk

Chemical Risk without Concurrent External Exposure!

Cumulative Risk Estimation for Chemical Mixtures

In reality, humans are always exposed to a combination of toxic substances and seldom to a single agent. Simultaneous exposure to a multitude of chemicals could result in unexpected consequences. The combined risk may lead to greater or less than a simple summation of the effects induced by chemicals given individually. Here, a method is proposed for estimating the cumulative risk which is the ...

Chemical risk assessment in a chemical laboratory based on three different techniques

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...

Chemical restraint in nursing older people.

The inappropriate and over-prescribing of medication is an area of nursing fraught with legal and ethical considerations. It can lead to people being chemically restrained and must only be used in exceptional situations. Therapeutic alternatives should take precedent. This article reviews studies on chemical restraint that show high levels of neuroleptic drug prescribing, including pro re nata ...

Deconfinement at finite chemical potential

In a confining, renormalisable, Dyson-Schwinger equation model of two-flavour QCD we explore the chemical-potential dependence of the dressed-quark propagator, which provides a means of determining the behaviour of the chiral and deconfinement order parameters, and low-energy pion observables. We find coincident, first order deconfinement and chiral symmetry restoration transitions at μc = 375M...
