Jianhu Lake, a small plateau lake in Yunnan Province, was selected as the study area. The spatio-temporal distributions of microplastics in water of Jianhu Lake were studied, and the microplastic fluxes from the influent and effluent rivers were explored through field sample collection and laboratory experiment. Then, the source or sink effects of small plateau lakes on microplastics were revealed. The results showed that the average abundances of microplastics in water of Jianhu Lake were (4.80±2.85) and (12.61±8.00) n/m3 in wet and dry seasons, respectively. The average monthly fluxes into the lake were (55.59×106) and (3.82×106) n, respectively. The monthly fluxes out of the lake were (13.70×106) and (9.80×106) n, respectively. The rayon (RY), polyethylene terephthalate (PET), and low density styrene-butadiene-styrene (SBS) were the main polymers types in water of Jianhu Lake. The degree of microplastic pollution in water of Jianhu Lake was higher in the dry season than that in the wet season. The microplastics from influent rivers had a significant contribution to the accumulation of microplastics in water of Jianhu Lake. Generally, Jianhu Lake was the sink of microplastics, while the "source" and "sink" roles of lakes on microplastics were the dynamic process under the different conditions.

以云南省高原小型湖泊剑湖为研究区,通过野外样品采集和室内分析实验,研究湖泊水体中微塑料时空分布和入出湖河流通量,揭示高原小型湖泊对微塑料的源/汇作用.结果显示,丰水期和枯水期剑湖水体中微塑料平均丰度分别为(4.80±2.85)和(12.61±8.00)n/m3,入湖平均月通量分别为(55.59×106)和(3.82×106)n,出湖月通量分别为(13.70×106)和(9.80×106)n.剑湖水体中微塑料聚合物主要类型为人造丝(RY)、聚对苯二甲酸乙二醇酯(PET)、低密度苯乙烯-丁二烯-苯乙烯(SBS).枯水期剑湖水体微塑料污染程度高于丰水期,入湖河流微塑料输入对剑湖水体微塑料累积具有显著贡献.总体上,剑湖是微塑料的“汇”,但在不同条件下,湖泊对微塑料的“源”和“汇”作用处于动态变化过程.

以云南省高原小型湖泊剑湖为研究区,通过野外样品采集和室内分析实验,研究湖泊水体中微塑料时空分布和入出湖河流通量,揭示高原小型湖泊对微塑料的源/汇作用.结果显示,丰水期和枯水期剑湖水体中微塑料平均丰度分别为(4.80±2.85)和(12.61±8.00)n/m3,入湖平均月通量分别为(55.59×106)和(3.82×106)n,出湖月通量分别为(13.70×106)和(9.80×106)n.剑湖水体中微塑料聚合物主要类型为人造丝(RY)、聚对苯二甲酸乙二醇酯(PET)、低密度苯乙烯-丁二烯-苯乙烯(SBS).枯水期剑湖水体微塑料污染程度高于丰水期,入湖河流微塑料输入对剑湖水体微塑料累积具有显著贡献.总体上,剑湖是微塑料的“汇”,但在不同条件下,湖泊对微塑料的“源”和“汇”作用处于动态变化过程.

Jianhu Lake, a small plateau lake in Yunnan Province, was selected as the study area. The spatio-temporal distributions of microplastics in water of Jianhu Lake were studied, and the microplastic fluxes from the influent and effluent rivers were explored through field sample collection and laboratory experiment. Then, the source or sink effects of small plateau lakes on microplastics were revealed. The results showed that the average abundances of microplastics in water of Jianhu Lake were (4.80±2.85) and (12.61±8.00) n/m3 in wet and dry seasons, respectively. The average monthly fluxes into the lake were (55.59×106) and (3.82×106) n, respectively. The monthly fluxes out of the lake were (13.70×106) and (9.80×106) n, respectively. The rayon (RY), polyethylene terephthalate (PET), and low density styrene-butadiene-styrene (SBS) were the main polymers types in water of Jianhu Lake. The degree of microplastic pollution in water of Jianhu Lake was higher in the dry season than that in the wet season. The microplastics from influent rivers had a significant contribution to the accumulation of microplastics in water of Jianhu Lake. Generally, Jianhu Lake was the sink of microplastics, while the "source" and "sink" roles of lakes on microplastics were the dynamic process under the different conditions.
