Title: Metal concentrations in pearl oyster, Pinctada radiata, collected from Saudi Arabian coast of the Arabian Gulf

Abstract

The Arabian Gulf is a shallow semi-closed water body. Several industrial complexes have been established along its coast line during the past decade. The effluent from these facilities is being discharged into the Gulf. These discharges pose potential hazards to the marine environment of the Arabian Gulf. The Saudi Arabian government is striving to protect the marine environment of the Gulf and has commissioned several studies to assess the damage from the industrial and municipal discharges. In these studies, marine organisms, for example, fish, clams, sea urchins, oysters, and plankton, along with sediments and seawater, have been analyzed for various pollutants. This study reports metal concentrations in pearl oysters collected from the Saudi Arabian coastal areas of the Arabian Gulf.

  • In Saudi Arabia, trace metal enrichment of marine environment may result from a number of anthropogenic activities, especially from petroleum and petrochemical industry wastes. The objective of this study was to determine metal concentrations in the sediments from the Arabian Gulf coast of Saudi Arabia. This study may serve as baseline information for future evaluation of metal pollution in this region.
  • The role heavy metals (the non-degradable and commutative chemicals) play as pollutants is widely recognized. In the sea, accumulation of pollutants may cause the toxicity to the aquatic organism and subsequently transferred to man through the food chain. Among the major sources of metal contamination are industrial activities and mining. Natural processes such as volcanic eruptions, erosion and wind are also important. At many places, industrial and agricultural discharges were found primary source of metal poisoning of fish e.g. Poland, Canada. Highway or motorboat traffic has also been reported as a major contributor of the problem. Exposure to heavy metalsmore » through air, water and/or the food chain is known to induce a wide variety of toxic effects in humans and animals. Some of these heavy metals are considered as essential elements for normal physiological functions of the human as well as for the most of animals micronutrients but the higher levels may be toxic or harmful. Extensive studies have been carried out in many parts of the world to determine toxicity and bio-accumulation of these metals in fish and other marine flora and fauna. However, there is a gap in our knowledge of the kind and extent of marine pollution by heavy metals around the coast of the United Arab Emirates (UAE) and the resultant contamination of the aquatic habitat. In continuation of our interest in marine environment, this study was designed to investigate and to compare the concentrations of cadmium, copper, manganese, nickel, lead and zinc in the skin, muscle and liver, and mercury in the muscle tissues only of Lutjanus fulviflamma and Epinephelus tauvina. These species have been selected as these are among the highly commercial fish species found in the trap fishery of United Arab Emirates. 25 refs., 3 figs., 5 tabs.« less
  • The role of trace metals in marine ecosystems has been keenly investigated during recent years. It is known that abundance of essential trace metals regulates the metal content in the organisms by homeostatic control mechanisms, which when cease to function cause essential trace metals to act in an either acutely or chronically toxic manner. Therefore, a correlation study based on essential and non-essential trace metal concentrations is imperative for extending the existing knowledge of bioaccumulation of trace metals in marine organisms. An attempt has been made in the present investigation to bring out quantitative correlations between the concentrations of iron,more » copper, lead and zinc in the edible muscle tissue of six species of marine fish: Salmon (salmon sole); tuna (thunnus thynnus); pomfret silver (pampus argenteus); Pomfret black (formioniger); long tail tuna (thynnus tonggel) and Indian oil sardine (sardinella longiceps). These fish are abundantly available in Pakistan along the coastal line of the Arabian Sea and have great commercial value. The computational analysis on the trace metal correlation was conducted using an MSTAT statistical package.« less
  • Acids, bases and neutral nitrogen compounds from high-boiling petroleum distillates were separated and further fractionated into fractions containing nitrogen compound types by HPLC on neutral alumina. Acids and bases were separated with anion and cation exchange resins respectively while the neutral nitrogen compounds were removed by complexation with ferric chloride supported on Atapulgus clay. The HPLC fractions were characterized by potentiometric titration for their basic and nonbasic nitrogen contents while infrared spectroscopy was used for the quantitative determination of major compound types present which are pyridines, pyrroles, amides, phenols and carboxylic acids. Characterization of individual nitrogen compounds was accomplished usingmore » gas chromatography and gas chromatography-mass spectrometry. The nitrogen compounds identified belong to three compound types which are pyridine, pyrrole and amide.« less
  • The shear velocity structure of the shallow upper mantle beneath the Arabian Shield has been modeled by inverting new Rayleigh wave phase velocity measurements between 45 and 140 s together with previously published Rayleigh wave group velocity measurement between 10 and 45 s. For measuring phase velocities, we applied a modified array method that minimizes the distortion of raypaths by lateral heterogeneity. The new shear velocity model shows a broad low velocity region in the lithospheric mantle across the Shield and a low velocity region at depths {ge} 150 km localized along the Red Sea coast and Makkah-Madinah-Nafud (MMN) volcanicmore » line. The velocity reduction in the upper mantle corresponds to a temperature anomaly of {approx}250-330 K. These finding, in particular the region of continuous low velocities along the Red Sea and MMN volcanic line, do not support interpretations for the origin of the Cenozoic plateau uplift and volcanism on the Shield invoking two separate plumes. When combined with images of the 410 and 660 km discontinuities beneath the southern part of the Arabian Shield, body wave tomographic models, a S-wave polarization analysis, and SKS splitting results, our new model supports an interpretation invoking a thermal upwelling of warm mantle rock originating in the lower mantle under Africa that crosses through the transition zone beneath Ethiopia and moves to the north and northwest under the eastern margin of the Red Sea and the Arabian Shield. In this interpretation, the difference in mean elevation between the Platform and Shield can be attributed to isostatic uplift caused by heating of the lithospheric mantle under the Shield, with significantly higher region along the Red Sea possibly resulting from a combination of lithosphere thinning and dynamic uplift.« less
