POPs have low solubility in water but are easily captured by solid particles, and are soluble in organic fluids (oils, fats, and liquid fuels). POPs are not easily degraded in the environment due to their stability and low decomposition rates. Due to this capacity for long-range transport, POP environmental contamination is extensive, even in ...
Persistent organic pollutants (POPs) are organic substances that persist in the environment, accumulate in living organisms and pose a risk to our health and the environment.

In her exhaustively researched 1962 book, "Silent Spring," marine biologist and science journalist Rachel Carlson alerted the world to the environmental destruction and health devastation that POPs were causing. Even though Carson drew on a wealth of studies publish...
In 1995, the United Nations Environment Programme (UNEP) commissioned an assessment of an initial list of 12 POPs that scientific studies had identified as especially threatening. Within a year, the UNEP had proposed the Stockholm Convention on Persistent Organic Pollutants, a treaty that was adopted in May of 2001 and that went into force in May o...
In 2009, the Stockholm Convention added another nine chemicals and chemical groups to the dirty dozen list. According to the Reuters news agency, some continue to have wide use as pesticides, as flame retardants, and in industrial processes.One, lindane, is used to treat head lice, though now it can only be purchased by prescription. Another is per...

Persistent organic pollutants (POPs) are hazardous chemicals that threaten human health and the planet’s ecosystems. POPs remain intact for a long time, widely distributed throughout the environment they accumulate and magnify in living organisms through the food chain and are toxic to both humans and wildlife.
