Investigation of phenolic compounds potential to reduce dust pollution of pomegranate trees.

The present study was carried out in two seasons from two areas at different distances from the industrial zone of Gabes city which is classified as a Mediterranean host-spot pollution region. Pomegranate tree were highly exposed to various industrial air pollutants containing Zn and Cu. The relation between Zn, Cu, morphological, physiological and biochemical changes induced in pomegranate leaves was evaluated based to the measurement of leaf heavy metals, leaf changes, total phenolic content and quali-quantification of individual phenol profile by LC-ESI-MS.

Suitability of four main Mediterranean tree crops for their growth in peri-urban agriculture and restoration (Gabes, Tunisia).

In order to increase the knowledge about crop tolerance to air pollutants in the different agroclimatic zones of the world, so that they can be efficiently considered for improving peri-urban agriculture, increasing the success of restoration projects, or enhancing air quality in polluted sites, the suitability of four economical valuable tree crops of the Mediterranean agriculture were studied under field conditions: date palm tree (Phoenix dactylifera L.), pomegranate (Punica granatum L.), fig tree (Ficus carica L.
