Many things came out of the recent UN Stockholm Convention on Persistent Organic Pollutants , or POPs Convention (April 25-29, 2011), but the most valuable in many people’s opinion is the addition of Endosulfan to a growing list of highly dangerous chemicals, called by one pundit, “The worst of the worst.”

Endosulfan is a highly toxic, Class I pesticide. Like its closest relative, DDT, which was banned about 40 years ago based on severely detrimental health and environmental effects, endosulfan is an organochlorine, a class of pesticides known for their toxicity at every level in the living world. In fact, in 2010 the U.S. Environmental Protection Agency said endosulfan’s health risks were actually more far-reaching than previously calculated or suspected.

The Stockholm Convention on Persistent Organic Pollutants, also known as the “POPs Treaty”, has been trying since 1995 to protect the world’s population from chemicals and pesticides uses in agriculture and industry that are known, even at very low levels, to cause cancer, central nervous system (CNS) disorders even in mature individuals, immune system failures, reproductive disorders, and delay or complete absence of certain infant and child (physical and mental) developmental paradigms. These chemicals are suspected of causing autism, ADHD, Central Auditory Processing Disorder, and Cerebral Palsy, to name a few.

POPs are persistent in the environment, building up in living organisms and demonstrating adverse effects on their health and development. POPs also move, traveling thousands of miles from their point of origin to infest and infect some of the last unspoiled wildernesses on the globe. For example, near the Arctic Circle, the presence of POPs are so prevalent that levels of HCH (Hexachlorocyclohexane), PFOS (perfluorooctane sulfonate) and endosulfan actually exceed those further south, even though the chemicals are not used in the Arctic.
