Diethylstilbestrol (DES) is a synthetic nonsteroidal estrogen that was first synthesized in 1938. Human exposure to DES has allegedly occurred through diverse sources, such as dietary ingestion from supplemented cattle feed and medical treatment for certain conditions, including breast and prostate cancers. From 1940 to 1970, DES was actually given to pregnant women in the […]

Green Chemistry Articles

According to my good friend chemist Martyn Poliakoff, the principles of green chemistry should be as easy as A,B,C. Or, more precisely, PRODUCTIVELY. Poliakoff, who is Prof of Chemistry at Nottingham University and famed for his pioneering work with supercritical fluids (SCFs), PRODUCTIVELY spells out – Prevent wastesRenewable materialsOmit derivitization stepsDegradable chemical productsUse safe synthetic […]
