Anders Hansson, chief archaeologist at Jamtli, says that they are stepping up in the spring.

- We collect pollen three times a week and when it is high season it gets four times a week.

The material is then sent to Umeå where it is analyzed and from there they receive a report which ends up on pollenrapporten.se. The measuring station, which has now been at Jamtli for 13 years, is available to simplify the everyday life of those with pollen allergy.

- It is for those who are allergic to have control, so that they know when they should not sleep with the window open or to smell the clothes, Anders says.
