Easter bonfires are causing an increased concentration in particulate matter in the air in some parts of the Netherlands, particularly in Overijssel and Achterhoek. "Especially people with lung diseases such as asthma and COPD, and (older) people with cardiovascular disease may suffer", public health institute RIVM warns, NOS reports.
According to the RIVM, the problem lies in the calm weather with not much wind. As a result, smoke and particulate matter can remain in place for a long time. The institute warns people to avoid the smoke as much as possible.
