Persistent Organic Pollutants (POPs)
ALS Environmental are able to support customers in complying with Waste Management 3 (WM3) by offering a full POPs suite. Persistent Organics Pollutants (POPs) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes.
Industrial production of chloroparaffins started as far back as 1930. Similar to PCB the properties of chloroparaffins were desirable for many applications. High chemical stability and flame resistance along with their viscous properties lead to a widespread global usage. Some of the most common application of chloroparaffins are as lubricants, flame retardants, plasticiser and as metal working fluids.
Needless to say the properties of the compounds that are desirable for industrial purposes are equally challenging when the compounds are released into the environment. They are non-biodegradable and bio accumulates in nature. Toxicity of the compounds varies with degree of chlorination and length of carbon chain.
