2014年12月至2015年3月期间，对卡塔尔海岸线沿线的8个沙滩和东海岸毗邻多哈海湾的4个海面站进行了调查。在所有沉积物和海水样品中都发现了微塑料，主要是低密度聚乙烯和聚丙烯。蓝色纤维，范围在1到5毫米之间，是存在的颗粒的主要类型。海面上的丰度从4.38×10(4)到1.46×10(6)个颗粒(-2)不等，最高值始终出现在离岸10公里处，这表明存在一个会聚带。海面样本没有检测到显著的时间变异性。潮间带沉积物中微塑料的浓度在36至228个颗粒m(-2)之间变化，8个海滩之间没有显著差异。这些结果表明微塑性污染在阿拉伯湾沿岸环境中的普遍存在。讨论了微塑料潜在的局部源和汇。
Eight sandy beaches along the coastline of Qatar and four sea surface stations on the eastern coast, adjacent to Doha Bay, were surveyed between December 2014 and March 2015. Microplastics, mainly low density polyethylene and polypropylene, were found in all samples of sediments and seawater. Blue fibers, ranging between 1 and 5 mm, were the dominant type of particle present. Abundances on the sea surface varied between 4.38 x 10(4) and 1.46 x 10(6) particles.km(-2) , with the highest values being consistently found 10 km offshore, suggesting the presence of a convergence zone. No significant temporal variability was detected for sea surface samples. The concentration of microplastics in intertidal sediments varied between 36 and 228 particles m(-2), with no significant differences among the 8 beaches examined. These results show the pervasiveness of microplastic pollution in coastal environments of the Arabian Gulf. Potential local sources and sinks for microplastics are discussed.
