Every year, a debris measurement is performed where you measure an area of 10 square meters in randomly selected places and see how many debris particles are measured in that area.
For 2020, the total number of measured debris particles per 10 square meters was 9.55 in Södertälje.
Which can be compared with this year when this figure is 4.14 junk particles.
When it comes to fimps, the figure was 5.99 fimps per area in 2020, compared with this year's figure of 2.69 fimps.
