The Standard – August 2011

Two popular phthalate plasticizers have been discontinued following a recent announcement that they would be regulated under REACH (link to REACH article),  Amid growing health concerns, and now international regulations, CIL has been developing an extensive line of phthalate standards, both parent and mono-ester metabolites, to assist in compliance monitoring and human exposure evaluation.

The EPA has added bisphenol A, a chemical used in the production of plastic goods, to the list of chemicals being studied for potential regulation. Health concerns arising from the volume of bisphenol A released into the environment have led to discussion on the need for further investigation.

In April 2011, the fifth meeting of the Conference of the Parties (COP5) to the Stockholm Convention was held in Geneva, Switzerland. At this meeting representatives from 127 nations agreed to add endosulfan to the list of POPs chemicals, making it the 22nd chemical banned under the Convention. There were, however ,some concessions to the use of this compound.
