Chemistry: An Introduction for Medical and Health Sciences

Professor Alan Jones is a recently retired Academic that is still involved in aspects of chemistry education. For many years Alan Jones taught chemistry to health students at Nottingham Trent University.

"an excellent book to refresh long forgotten chemistry related-facts... full of cartoons that will give you a chuckle." (Accident and Emergency Nursing Journal, July 2006)"... well written and organized book... " (Education in Chemistry, January 2007)
