The Assassin Carbon Monoxide (CO)

The Health Council also gives an important #warning Off. In thousands of homes in the Netherlands, the concentration of carbon monoxide too high. They advise the cabinet to impose stricter requirements on the carbon monoxide detectors. Most detectors now only sound an alarm when there is a high concentration of carbon monoxide, about 25 ppm, but the lower concentrations are not measured, such as 6 ppm. And that's where it is. It turns out that physical damage can occur much earlier at much lower concentrations of carbon monoxide. If people are exposed to lower concentrations of carbon monoxide for a long time, this can cause problems with the heart and blood vessels. That has to do with your blood taking less oxygen when you come into contact with carbon monoxide. This in turn reduces oxygen to your organs, affecting the heart and blood vessels. In addition, carbon monoxide disrupts important biological processes in the body.

Research on the effect of lower concentrations of carbon monoxide on human beings was carried out in 2010 by the WHO (World Health Organisation) and in 2017. #health - Yes.
The study from Sweden in 2017 showed that pregnant women when exposed during pregnancy may have adverse effects on the neurological development of the foetus.

There is already a plan within the Safety Research Council on the table to amend the law most likely by 2020.
Only certified installation companies will only be allowed to maintain the central heating boilers, gas stoves, fireplaces, geysers, etc. Carbon monoxide poisoning occurs at 25 ppm.
According to the Health Council and the WHO, that is insufficient.
Carbon monoxide, according to them already occurs at 6 ppm, such as being exposed to lower concentrations of carbon monoxide for a long time, giving the above physical complaints.
Most carbon monoxide detectors on the market only issue a warning at 25 ppm. A few at 10 ppm, but it would be even better, according to the WHO, if the detectors already issue a warning at 5 ppm. In America, incidentally, such detectors can be found on the market.
