TO EVALUATE THE DEGRADATION OF THE NATURAL ECOSYSTEM OF ATHENS METROPOLITAN AREA AFFECTED BY AIR POLLUTION AND TO FIND POSSIBLE RECLAMATION WAYS FOR IT.

POSSIBLE REDUCTION OF PRODUCTIVITY OF THE NATURAL ECOSYSTEM OF ATHENS METROPOLITAN AREA IS CONSIDERED LOOKING FOR THE EFFECTS OF AIR POLLUTION ON IT.

OBSERVATIONS AND MEASUREMENTS DEAL MAINLY WITH:

1) TOTAL ABOVE GROUND BIOMASS

2) LEAF AREA INDEX

3) RATIO OF GREEN TO NON-GREEN BIOMASS

4) SEASONAL FLUCTUATIONS OF PRODUCTIVITY.

THE FOLLOWING SUBJECTS ARE ALSO CONSIDERED:

A) SOIL METABOLISM, USING CO2 EVOLUTION AS PARAMETER

B) ANATOMICAL OBSERVATIONS, MAINLY ON NEEDLES FROM CONIFERS OF MT PARNITHA AND PENTELI

C) CORRELATION BETWEEN INSECTS AND INSECT-POLLINATED PLANTS.
