A study on controlling chloroform in drinking water using chlorine dioxide as first disinfector followed by chlorine as secondary disinfector was reported. Using chlorine dioxide as pretreatment disinfector would decrease the concentration of chloroform in drinking water. Chlorination after chlorine dioxide pretreatment may be influenced by reaction time and temperature. Additionally, when the mixture which composed of chlorine and chlorine dioxide was used, with the content of chlorine dioxide in mixture disinfector increasing, chloroform in the sample treated by it may decrease obviously.

Bisphenol A is an important organic chemical raw material, mainly used for the production of polycarbonate, epoxy resin, polysulfone resin and other polymer materials. Research institutions have found that bisphenol A may cause diseases such as human heart and liver, and especially the release of bisphenol A from baby bottles may cause abnormal hormone secretion and brain development disorders in babies.
Recently, following the announcement of the ban on the use of bisphenol A in food packaging and contact materials by Canada and the United States, a member of the French Parliament has jointly proposed a proposal to prohibit the use of bisphenol A in food packaging and contact materials. The new regulations for food packaging and contact materials in Europe and the United States should cause great concern from all parties.
