微塑料（MP）是水生系统中新近认识的一种环境污染类型；然而，没有对这些污染物进行监测，主要是由于缺乏常规量化。在用 90 微米 WP2 网收集的网样本中，通过光学显微镜对远洋 MP 丰度进行量化，并根据近海梯度、深度和季节进行评估；相同的样品用于浮游动物分析。 MP丰度与10(2)-10(4)颗粒m(-3)相似，夏季近海梯度不明显，冬季近海梯度增加。深层的 MP 丰度受到上层浮游动物丰度的正向影响，并且冬季与夏季相比显着降低。这些发现表明生物和非生物因素导致 MP 分布的异质性，并表明为其他目的收集的样本可用于波罗的海 MP 的量化，从而促进将 MP 评估纳入现有监测计划。 (C) 2015 Elsevier Ltd. 保留所有权利。
Microplastics (MPs) are a newly recognized type of environmental pollution in aquatic systems; however no monitoring of these contaminants is conducted, mostly due to the lack of routine quantification. In the net samples collected with a 90-mu m WP2 net, pelagic MP abundance was quantified by light microscopy and evaluated as a function of inshore-offshore gradient, depth, and season; the same samples were used for zooplankton analysis. The MP abundance was similar to 10(2)-10(4) particles m(-3), with no significant inshore-offshore gradient during summer but increasing offshore in winter. MP abundance in deeper layers was positively affected by zooplankton abundance in the upper layers and significantly lower during winter compared to summer. These findings indicate heterogeneity of MP distribution due to biotic and abiotic factors and suggest that samples collected for other purposes can be used for quantification of MPs in the Baltic Sea, thus facilitating integration of MP assessment into existing monitoring schemes.
