В данном исследовании изучалось гранулометрическое распределение песков в двух линиях исследования - приливной и шельфовой зонах вдоль побережья сектора Газа, Палестина. Кроме того, в исследовании оценивались концентрации Zn, Pb, Mn, Cu, Co и Cd в отложениях исследуемого района. Было отобрано 30 участков отбора проб, разделенных между приливной и шельфовой зонами. Гранулометрический состав проб песка определялся методом просеивания. Концентрации тяжелых металлов определялись и анализировались с помощью пламенного атомно-абсорбционного спектрофотометра. Загрязнение выбранными тяжелыми металлами в донных отложениях исследуемого района было ниже пределов стандартов EPA и Онтарио. В то время как концентрация Cd была выше этих стандартных пределов. Сброс бытовых неочищенных сточных вод и рыболовная деятельность в этом районе, возможно, являются основными источниками наблюдаемого повышенного уровня загрязнения тяжелыми металлами, особенно кадмием.
