Last year, the incidence of tuberculosis (TB) in the Netherlands fell sharply. The 17% drop is the largest in fifty years. In 2020, 623 cases were notified compared to 754 in 2019.

More nitrogen and phosphorus have been ending up in the soil on farms since 2015. As a result, nitrate concentrations have been rising since 2017 in leachates and ditch water from those farms.

In 2019, the calculated concentrations of nitrogen dioxide (NO2) and particulate matter (PM10) were below the European limit values ​​in almost the whole of the Netherlands. Locally, the limit value for nitrogen dioxide is still being exceeded.
