The spatial distribution, sources and characteristics of marine litter (ML) from 36 locations spread over 12 beaches along the west coast of Qatar have been assessed. A total of 2376 ML items with varying sizes were found with an average abundance of 1.98 items/m². The order of abundance of ML along the coast was as follows: plastics (71.4%) > metal (9.3%) > glass (5.1%) > paper (4.4%) > fabric (4.0%) > rubber (3.9%) > processed wood (2.0%). Locations in the south and northwest coasts of Qatar had significantly higher concentrations of ML. Surprisingly, nearly 47% of the beached polyethylene terephthalate (PET) bottles were derived from the countries bordering the Arabian/Persian Gulf (Gulf), and most of them were produced in the last 2 years. The plastic materials were drifted by winds and currents to the Qatar coast. Gulf circulation provides evidence to the pathways of ML beached on the Qatar coast.

评估了卡塔尔西海岸12个海滩上36个地点的海洋垃圾（ML）的空间分布，来源和特征。总共发现2376 ML大小不一的物品，平均丰度为1.98物品/ m ²。沿海地区ML的丰富程度顺序如下：塑料（71.4％）>金属（9.3％）>玻璃（5.1％）>纸张（4.4％）>织物（4.0％）>橡胶（3.9％）>已加工木材（2.0％）。卡塔尔南部和西北沿海地区的ML浓度明显较高。令人惊讶的是，近47％的沙滩聚对苯二甲酸乙二醇酯（PET）瓶来自与阿拉伯/波斯湾（Gulf）接壤的国家，其中大多数是在过去两年内生产的。塑料材料随风和海流漂流到卡塔尔海岸。海湾环流为卡塔尔海岸的ML滩涂路径提供了证据。
