| Zusammenfassung |
| Two areas in the Atlantic Forest (São Paulo State, Brazil), with contrasting
environments in respect of human occupation, were monitored from 1999 to
2001. One area named PEFI (23°38'08''-23°40'18'' S and
46°36'48''-46°38'00'' W) at an altitude of 798 m a.s.l., 526.4 ha
in area and about 50 km from the sea, lies in a State Park within the largest metropolis of South
America - São Paulo. The other area, named CUNHA (between 23°13'18'' and
23°16'10'' S and 45°02'53'' and 45°05'15'' W) about 1050 m a.s.l. with an
area of 2854 ha and about 15 km from the sea, is also within a State Park in
the Atlantic Forest, but is surrounded by rural areas and small villages. For
each area, the rainfall and throughfall chemistry were examined and pH and
Na+, K+, Mg2+, Ca2+, NH4+, Cl-, NO3- and SO42- as well as trace metals were
determined. Compared with PEFI, CUNHA is characterised by low chemical fluxes
and the largest differences are for the ions such as Ca2+, H+, NO3- and
SO42- which are mainly anthropogenic in origin. Differences in throughfall chemical
fluxes are linked to the nutritional status of the trees. |
