These potentially harmful chemicals are very important to the mining industry, construction and highway industries and also the military. Chemists, who also make recommendations for safe handling and disposal, carry out development of these materials. Chemical analysts may be involved in developing test procedures and testing for the presence of drugs. Errors in these tests, producing false negative or false positive results, can cause irreparable harm to individuals and the public. Food chemistry is an important contributor to the nutrition of the public.
Chemists develop coloring agents, preservatives and flavours, which are safe for food use.
DNA testing, developed and applied by chemists has resulted in several innocent people being released from prison. Chemists are also involved in forensic science. Fire retardant coatings for clothing, and Kevlar for bulletproof vests are products of a viable chemical industry, which contribute to the safety of the public. Fire extinguishing materials are also developed and improved by the chemical profession. All new material is the result of chemical research.
