“…Biosphere Reserve, Iran [50] and Farasan Island [51] (Table 3). Recently, trace elements were studied in the same area and it was found that data obtained through the current study could be comparable with previous studies [15,22,23]. However, results of Almahasheer [25] were incredibly higher than that recorded in mangrove sediments in the current study as well as previous studies all over the world.…”

“…In addition, the average concentration of Pb (26.61 µg g -1 ) was higher than those recorded in some areas reported in the previous studies except for Shriadah [49] and Usama et al [51] in Abu-Dhabi and Farasan Island, respectively. The average concentration of Zn (48.48 µg g -1 ) was higher than those recorded in the coastal areas of the Arabian Gulf and the Red Sea except for Tubli, Bahrain [15], Hara…”

“…Nowadays, the mangrove ecosystem has been increasingly threatened as a result of human interference, including manufacturing and agro-based industries, huge urbanization, oil spills, domestic wastes and human pressure of dredging and land reclamation that led to serious pollutants [e.g. [14][15][16][17][18]. Unfortunately, because of a serious threat due to the contamination of trace elements, some areas of mangroves are being devastated all over the world [19].…”

“…Several studies investigated the concentration of trace elements in sediments of coastal areas along the central Arabian Gulf shoreline of Saudi Arabia, including some mangrove stands [24]. More recently, Al-Kahtany et al [15] and Almahasheer [25] assessed the concentrations of trace elements in the mangrove swamps of Tarut Island. Results obtained from previous studies were significantly different.…”

Spatial distribution and potential ecological risk assessment of some trace elements in sediments and grey mangrove (Avicennia marina) along the Arabian Gulf coast, Saudi Arabia

AbstractTo assess trace element concentrations (Zn, Cu, Pb, Cr, Cd and Ni) in the mangrove swamps along the Saudi coast of the Arabian Gulf, thirteen samples of surface sediment and leaves of grey mangrove, Avicennia marina were collected and analyzed. The detected trace element contents (μg g-1) in surface sediments were in the following descending order according to their mean values; Cr (49.18) > Zn (48.48) > Cu (43.06) > Pb (26.61) > Ni (22.88) > Cd (3.21). The results showed that the average concentrations of Cd and Pb exceeded their world average concentration of shale. The geo-accumulation, potential ecological risk and toxicity response indices demonstrated that trace elements have posed a considerable ecological risk, especially Cd. The inter-relationships between physico-chemical characters and trace elements suggests that grained particles of mud represent a noteworthy character in the distribution of trace elements compared to organic materials. Moreover, the results revealed that Zn was clearly bioaccumulated in leaf tissues A. marina. Dredging, landfilling, sewage effluents and oil pollution can be the paramount sources of pollution in the area under investigation.

“…Sea-level rise, storm damage, warming temperatures and changes in precipitation are all likely to impact mangroves in the future [179][180][181][183][184][185] due to effects on forest health and productivity, photosynthesis, respiration, recruitment, biomass allocation, inundation periods, sediment input, accretion rates and ground-water levels [178]. It is estimated that approximately 96% of all the RSA coastal wetlands, including mangroves, will be at risk by the end of this century from a combination of sea-level rise and subsidence, compounded with the negative effects of pollution and coastal squeeze [33,181,[186][187][188]. Mangroves also play a vital role in mitigating climate change by absorbing and storing substantial amounts of CO 2 on an annual basis [176].…”

A Regional Review of Marine and Coastal Impacts of Climate Change on the ROPME Sea Area

et al. 2021

View full text Add to dashboard Cite

The Regional Organization for the Protection of the Marine Environment (ROPME) Sea Area (RSA) in the northern Indian Ocean, which comprises the Gulf, the Gulf of Oman and the northern Arabian Sea, already experiences naturally extreme environmental conditions and incorporates one of the world’s warmest seas. There is growing evidence that climate change is already affecting the environmental conditions of the RSA, in areas including sea temperature, salinity, dissolved oxygen, pH, and sea level, which are set to continue changing over time. The cumulative impacts of these changes on coastal and marine ecosystems and dependent societies are less well documented, but are likely to be significant, especially in the context of other human stressors. This review represents the first regional synthesis of observed and predicted climate change impacts on marine and coastal ecosystems across the ROPME Sea Area and their implications for dependent societies. Climate-driven ecological changes include loss of coral reefs due to bleaching and the decline of fish populations, while socio-economic impacts include physical impacts from sea-level rise and cyclones, risk to commercial wild capture fisheries, disruption to desalination systems and loss of tourism. The compilation of this review is aimed to support the development of targeted adaptation actions and to direct future research within the RSA.
