Sediment core samples from high tide lines and in submerged zones as well as surface water samples from eight beaches of Tenerife were analysed. Sampling was conducted over a period of one year in intervals of 5 weeks. The majority of particles were found in the high tide sediment (66%), followed by water samples (23%) and finally in sediment from submerged zones (11%). Regarding the particle amount per volume (items/L), accumulation in sediment samples was statistically higher compared to water samples. Mean values of items/L were higher in high tide sediments. In high tide and water samples, mostly white and transparent particles >1 mm were found. More than 70% were represented by fragments. In sediments from submerged zones, yellow and blue microparticles (<1 mm) were predominant and 61.9% consisted of fibres. Larger particles were mainly identified as PP, PE, PS, PTFE and PVC, while polymer types of smaller particles were more variable.
对来自特内里费岛 8 个海滩高潮线和淹没区的沉积物芯样以及表层水样进行了分析。在一年的时间里,每隔 5 周进行一次采样。大多数颗粒存在于高潮沉积物中(66%),其次是水样(23%),最后是淹没区沉积物(11%)。就每体积的颗粒数量(项/L)而言,与水样相比,沉积物样品中的积累在统计学上更高。高潮水和水样中的项/L 平均值更高。在高潮和水样中,主要发现 >1 毫米的白色和透明颗粒。超过 70%是碎片。在淹没区沉积物中,主要是黄色和蓝色的<1 毫米的微粒,其中 61.9%由纤维组成。较大的颗粒主要被鉴定为 PP、PE、PS、PTFE 和 PVC,而较小颗粒的聚合物类型则更加多样化。
