Abstract：
Bandon Bay is a very fertile bay for coastal aquaculture, especially for blood cockles (Anadara granosa). Its structural pattern supports the flow of nutrients which directly sent from many rivers resulted the high production capacity of blood cockle at the top level in the country. Besides organic compounds present in sediment, inorganic substances are essential for growth, survival and shell development of blood cockles. A comparative study of minerals and oxide compounds which accumulated in the sediments at eight stations around the cockle culture area was conducted. These stations are located along the estuaries at Tha Thong, Tha Chang, Phum Riang, and Tapi. The proportion of oxide compounds were determinedusing X-Ray Fluorescence (XRF) technique and minerals were analyzed by Atomic Absorption Spectroscopy (AAS). Results showed that sediment characteristics, oxide composition and the amount of minerals among the stations are different from each other. The sediments of the eastern and the western coasts were characterized as crumble clay and muddy sand, respectively. Twelve types of oxide compounds, namely SiO2, Al2O3, Fe2O3, K2O, Cl, MgO, Na2O, SO3, CaO, TiO2, MnO, P2O5 were found in various quantities, with SiO2, Al2O3, and Fe2O3 were the fundamental minerals ranging from 85.64-90.82%. Tha Thong estuary in the east coast showed highly significant quantities (P<0.05) of potassium, calcium and manganese compared to the other estuaries.
摘要：
班顿湾是沿海水产养殖的肥沃海湾，尤其是对于血鸟（Anadaragranosa）。它的结构模式支持从许多河流直接输送的营养物质的流动，导致了该国最高水平的血球菌的高生产能力。除了沉积物中存在的有机化合物，无机物是生长所必需的,血鸟的生存和贝壳发育。对cockle养殖区周围八个站点的沉积物中积累的矿物质和氧化物进行了比较研究。这些车站位于ThaThong河口沿线，ThaChang,PhumRiang,还有Tapi.使用X射线荧光（XRF）技术确定氧化物化合物的比例，并通过原子吸收光谱（AAS）分析矿物。结果表明，沉积物特征，各站之间的氧化物成分和矿物质含量各不相同。东部和西部海岸的沉积物的特征是破碎的粘土和泥沙，分别。十二种氧化物，即SiO2，Al2O3，Fe2O3，K2O，Cl,MgO,Na2O,SO3,CaO,TiO2,MnO,发现了不同数量的P2O5，SiO2，Al2O3和Fe2O3是85.64-90.82%的基本矿物。东海岸的ThaThong河口显示出极显著的钾含量(P<0.05)，与其他河口相比，钙和锰。
