  The present study aimed to investigate the sensitivity of an indigenous leguminous plant species of Oman, Prosopis cineraria (ghaff tree), to SO2 pollutant. Plants were exposed to 0, 25, 50, 100 and 150 ppb SO2 for 30 min daily for the period of ten weeks, under light and dark conditions. The formation of marginal necrotic areas on leaflets was seen as the first symptom of SO2 injury in P. cineraria plants. Leaf senescence was highly significant (p<0.01) in plants exposed to SO2 in light conditions and significant (p<0.05) in plants exposed to SO2 in dark conditions compared with control plants. There was significant (p<0.05) decrease in Relative Growth Rate per week in plants exposed to SO2 in both light and dark treatments compared with control plants, but more pronounced reduction in light conditions. Stomatal conductance was significantly (p<0.01) reduced after SO2 exposure in both light and dark treatments. These results became the first record of Oman indigenous plant species showing confirmed injuries as a result of exposure of SO2 concentrations.

  An investigation of the bioaccumulation of heavy metals in green turtles at Ras Al Hadd turtle reserve (Oman) was undertaken. A total of 12 heavy metals in liver of hatchlings and egg yolk of eggs were determined by using Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) analytical methods. Random samples collected over 2 year period from different beaches at Ras Al Hadd reserve. The average metal contents varied from not detectable (Sn) to 8.58±1.03 (Zn) μg gG1 wet weight in egg yolk and 0.01±0.00 (Sn) to 23.16±1.84 (Zn) μg gG1 wet weight in liver of hatchlings. The concentration level of metals in egg yolk of freshly laid eggs occurred in the following order: Zn > Cu > Mn > Cd > V > Se > Hg > Cr > Pb > Ni > Co and in liver of untreated hatchlings occurred in the following order: Zn > Cu > Mn > V > Cr > Hg > Se > Cd > Pb > Co > Ni > Sn. Laboratory simulation with experimental metal contamination in sands and waters showed a significant accumulation of Cr, Co, Cu, Pb, Hg, Ni and Se in egg yolk and Cd, Cr, Cu, Pb, Mn, Hg, Ni, Se and V in liver compared with controls. Toxicological studies on the effect of heavy metals are urgently needed for the endangered population of green turtles.
