摘要

The aim of this study is to quantify lead and copper concentrations deposited on plant species exposed in different habitats of Abidjan in order to assess air quality of Abidjan. Five species were used Barleria prionitis, Cassia surattensis, Duranta repens, Ficus benjamina, Jatropha interrigima and exposed in parks, main roads, industrial and residential zones. Leaf samples were collected and the concentrations of copper and lead were carried out by inductively coupled plasma mass spectrometry. Roads generally showed high levels of copper and lead and the highest values reached 13 mg.g~(-1) and 7.5 mg.g~(-1) respectively. While the lowest were found in Parks with the values 2 mg.g~(-1) for Cu and 0.5 mg.g-1 for Pb. These results suggest that the major source of pollution were car exhaust. However, C.surattensis at roadsides showed the highest deposition of Cu and Pb. A significant positive correlation between lead and copper concentration in three leaves species, Cassia surrattensis (r = 0.974; p = 0.0043), Duranta repens (r = 0.824; p = 0.0057) and Jatropha interrigima (r = 0927; p = 0.00001) were found.
