Content of chlorophylls a and b and of carotenoids has been investigated spectrophotometrically in needles of Pinus halepensis during the year, in polluted and unpolluted localities. Concentrations of all pigments were low in general; they fluctuated monthly and showed a tendency to decrease in the needles from polluted sites. The decrease appears to correspond with the level of air pollution. The chlorophylls a:b ratio, however, could apparently not be considered as time and degree of site pollution dependent.
