Resumen:
In leaves of Morus alba was analyzed the variation in air particle deposition, during a complete vegetative cycle (spring, summer and end of autumn), in urban and suburban area of San Juan (Argentina). The study was made in San Juan sampling 40 trees randomly selected. Data obtained were statistically analyzed using the ANOVA test. The treetop mean external foliar area represents 52.1±13.4 % in urban and 55.2±9.2% in suburban areas. No statistical differences were found in particles accumulated in internal and external sectors of the treetop. Accumulated particles by cm2 of foliage did not differ statistically between urban and suburban area. Taking into account the forest census, the mean foliage area, and the particulate/cm2, total solids deposited were 9.9 kg (spring) and 295.7 kg (fall).
