The uptake of and structural changes induced by trichloroacetic acid in the needles of scots pine seedlings
The uptake of trichloroacetic acid (TCA) and structural changes induced in the needles of Scots pine (Pinus sylvestris L.) seedlings were studied. Two exposure set-ups, a root route and an atmospheric route through the surfaces simulating the wet deposition of fog, were used. Both set-ups included t...
