The left ventricular ejection fraction (LVEF) test rate is increasingly used as a quality of care indicator for pa-. tients with heart failure. Our study produced benchmark LVEF test rates in a Medicare fee-for-service.
Toluene is a very good solvent because, unlike water, it can dissolve many organic compounds. In many commercial products, toluene is used as a solvent that is present in paint thinners, nail polish remover, glues, and correction fluid. Toluene has many uses in different industries.
It is used in agricultural sector against roundworms and hookworms. Toluene occurs naturally at low levels from crude oil and is usually produced in the processes of gasoline via a catalytic reformer, in an ethylene cracker or making coke from coal. It is widely used in industry, often as a substitute for benzene.
