continuous monitoring. Active sampling stations are expensive to acquire and maintain, so there has been an increasing search for cheaper alternatives. Vegetation has consistently been one of the solutions employed, and pine needles are among the most used...

Biomonitoring using vegetation is nowadays a common practice in environmental science, but depends a lot on the availability of the species able to be used in the target sampling points. Pine needles are one of the most used matrices in these types...

. In particular, references to several pine species are common (especially their needles). It is however unlikely that two samples exposed to the same environmental contamination but collected from dissimilar species present the same results. The differences may...

, Pinus mugo, Pinus sylvestris and Pinus cembra
needles were collected upon availability in 24 sampling sites that included remote
and rural areas but also some urban settlements like Reykjavík or Selfoss. In seven
of these sites it was possible...
