对经由湿性沉降而产生地学因子的砷(As)、镉(Cd)、钴(Co)、铬(Cr)、铜(Cu)、汞(Hg)、镍(Ni)、铅(Pb)和锌(Zn)的背景负荷进行了估算,而1990年代以来的大气沉降总量确定为超过背景值的5倍至多达20倍。经由河流输入的元素区分为地学因子和人类因子,呈现为不均匀分布。河流输入总量(包括扩散来源)估算为砷200、镉60、钴200、铬440、铜1300、汞50、镍300、铅1500和锌6000(t/a)。最高负荷来自波兰和波罗的海国家的河流。现有的监测网络对确定象氮和硫组分方面做了很好的工作,主要的不准确性来自整个公海大气输入方面的数据资料不充分。此外,有关沉降动力学精细的知识仍缺乏。类似的不充分性还来自河流输入物——既有溶解物质又有颗粒型。
Arsenic (As), Cadmium (Cd), Co (Co), Chromium (Cr), Copper (Cu), Mercury (Hg), Nickel (Ni), Lead (Pb) and Zinc (Zn) background loads, and the total amount of atmospheric deposition since the 1990s was determined to exceed 5 times the background value up to 20 times. Elements imported via rivers are divided into geo-logical factors and human factors, presenting an uneven distribution. Total river input, including sources of diffusion, was estimated as arsenic 200, cadmium 60, cobalt 200, chromium 440, copper 1300, mercury 50, nickel 300, lead 1500, and zinc 6000 (t / a). The highest loads come from the rivers of Poland and the Baltic States. Existing monitoring networks have done a good job of identifying nitrogen and sulfur components, with major inaccuracies resulting from inadequate data sources on the entire open ocean atmosphere. In addition, there is a lack of fine knowledge of sedimentation kinetics. Similar deficiencies also come from river inputs - both dissolved and granular.
