Use of Plants to Monitor Contamination of Air by SO sub(2) in and Around Refinery

In the vicinity of the Oman Mina Al-Fahal oil refinery in Muscat, sulfate accumulation was measured directly in plants as an indication of air pollution by sulfur dioxide. The plants included Ghaf Prosopis cineraria, neem Azadirachta indica, and date palm Phoenix dactilifera. While the measured SO s...

Description
Summary:In the vicinity of the Oman Mina Al-Fahal oil refinery in Muscat, sulfate accumulation was measured directly in plants as an indication of air pollution by sulfur dioxide. The plants included Ghaf Prosopis cineraria, neem Azadirachta indica, and date palm Phoenix dactilifera. While the measured SO sub(2) levels were below the National Ambient Air Quality Standard, visible emission damage was noted in almost all plants analyzed, as indicated by interveinal bifacial chlorosis of older leaves, especially on plants located closer to the refinery. Sulfate concentrations in the leaves of P. cineraria were much higher than those in leaves of the other two species, and the SO sub(4) content of leaves of P. cineraria varied according to distance from the refinery, which was also noted for the other two species.
