Every year about 1.5 million ticks bite someone in the Netherlands, especially between March and October. Most people will not get sick of that.

In 2017, concentrations of nitrogen dioxide and particulate matter in most parts of the Netherlands were below European limit values.

The European Food Safety Authority (EFSA) has published a provisional health-based guidance value for perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA).

One in 5 tick bites occurs in an urban area. Although most tick bites occur in the countryside, many people are bitten in urban areas as well.
