How small was the noise, evident from the fact that most newspapers barely felt the incident newsworthy. Often it was a small article which appeared not even on the front page. When some years ago soot were emitted by Shell over Voorne-Putten, which dominated the media for days.

However, the optimistic tone of DuPont spokesman about the incident was not quite right. In the months after the dust explosion was twice again hit. In April, the plant was shut down because it escaped toxic Viton. Again three months later Hydrogen fluoride was released. Thus the number of incidents was five in a period of two years.


In recent years are DuPont and successor Chem Ours clearly under fire. This is mainly due to the emissions of PFOA (raw material for Teflon) in GenX (the successor of PFOA). The substance is toxic and has been for many years emitted by DuPont. According to the RIVM were residents years exposed to high levels. Yet there is no more emitted than is allowed under the permit, zegt Chemours.

Or sick people have become the emissions seems obvious based vna the RIVM statements, but has not yet demonstrated. In the immediate vicinity of Chem Ours are no more cancer cases than in the rest of the country, has been shown several times.

It appears that in the very vicinity some people have an amount of PFOA in their blood, which uikomt above the extreme limit of the RIVM.

Chem Ours indicates that the company 2018 has announced that € 75 million will be invested in the Dordrecht plant, that the emissions 99% is reduced.

The authorization of Chem Ours may only annually 148 kilograms per year are emitted in the air and the water. In the old license was still 8435 kilogram.
