北极冰冻圈（如格陵兰冰盖、永久冻土、海冰、积雪）在北极气候变暖，人为污染物的储存和释放中起着重要作用。微塑料颗粒作为一种新兴的人为污染物，目前在全球海洋和陆地环境中普遍存在。本数据包括北极地区的河流、湖泊、积雪、海冰、海水和土壤沉积物中的微塑料丰度、形态、粒径、聚合物类型等数据以及在冰雪、河流和海冰的排放通量。本数据集微塑料的测量以傅里叶变换红外光谱仪（FTIR）和立体显微镜（stereomicroscope）为主。为了了解北极冰冻圈中的微塑料及其与其他环境矩阵的联系，本数据集旨在探讨北极地区微塑料相关研究的当前状况和关键挑战的识别。", "ds_source": "

The Arctic cryosphere, such as the Greenland ice sheet, permafrost, sea ice, and snow cover, plays an important role in the warming of the Arctic climate and the storage and release of anthropogenic pollutants. Microplastic particles, as an emerging anthropogenic pollutant, are currently widely present in marine and terrestrial environments worldwide. This data includes the abundance, morphology, particle size, polymer types, and emission fluxes of microplastics in rivers, lakes, snow cover, sea ice, seawater, and soil sediments in the Arctic region. The measurement of microplastics in this dataset is mainly carried out using Fourier transform infrared spectroscopy (FTIR) and stereo microscope. In order to understand microplastics in the Arctic cryosphere and their relationship with other environmental matrices, this dataset aims to explore the current status and identify key challenges in microplastic related research in the Arctic region.", "ds_time_res": "", "ds_acq_place": "Arctic", "ds_space_res": "", "ds_projection": "", "ds_process_way": "
