This article summarizes a University of California chemicals policy report commissioned by the California Legislature. The report makes the case that long-standing weaknesses in the Toxic Substances Control Act have produced a flawed chemicals market in the U.S. that "undervalues" the hazardous properties of chemicals relative to their function, price, and performance. These market conditions h...

Green Toxicology refers to the application of predictive toxicology in the sustainable development and production of new less harmful materials and chemicals, subsequently reducing waste and exposure. Built upon the foundation of "Green Chemistry" and "Green Engineering", "Green Toxicology" aims to shape future manufacturing processes and safe synthesis of chemicals in terms of environmental an...

An improved, simple, and facile synthesis of 3,4-dihydropyrimidin-2(1H)-ones by employing three-component, one-pot condensation reaction of β-keto ester, aromatic aldehydes, and urea or N-methylurea using LaCl3/ClCH2COOH as an inexpensive and green chemistry catalyst system under solvent-free conditions described. Compared with the classicalBiginelli reaction conditions, this method has the adv...

Chemists use atoms as the building blocks in reactions to design new molecules for materials, medicines, and much more. However, chemical elements on our planet are a finite resource, so we need prevent them from running out or being wasted. How do chemists this? The principles of Green Chemistry guide chemists, helping products both efficiently safely, while limiting preventing pollution along...
