Mercury makes children stupid

Methylmercury is a big danger for humans and environment, because it is enriched in the food chain For the humans the enrichment happens in brain and bone marrow. Especially at embryo and child/toddler age the methylmercury causes damages in the brain, resulting in loss of IQ (intelligence).

Therefore mercury emissions from incinerators or cement plants shall be as low as possible, using the best available techniques in flue gas cleaning. Reduction of mercury emissions to 10% of the existing legal limit of 30 µg/m3 is state of the art.

Because mercury emissions are distributed worldwide, the environmental program of United Nations, has initiated a worldwide agreement (similar to Kyoto protocol). In 2013, 128 countries have signed this agreement (www.mercuryconvention.org).

The AiO system is used to measure mercury as a meanvalue of 2 sorbent traps and one impinger sampling train. It provides quality assurance with evaluation of breakthrough and loss of internal standard. With these QA steps, the measured value have high accuracy, even at concentration levels below 5 µg/m3.
