The inclusion of atmospheric particles into the bark suber of ash trees.

A slow deposition of atmospheric components occurs on tree barks. One part of them can be incorporated into bark tissues. This work demonstrates that mineral particles are present inside the suber tissue in four-year-old ash tree stems.

A PIXE and ICP-MS analysis of metallic atmospheric contaminants in tree bark tissues, a basis for biomonitoring uses.

The qualitative and quantitative metallic content of tree barks of Argania spinosa (L.) Skeels were studied. Argania spinosa is an endemic species in Morocco.
