1.The single species exposure experiments were completed.(1)Completed the exposure experiments of Daphnia: The results show that D. magna can ingest MP particles whose density is higher than water;(2)Completed the exposure experiments of Zebrafish: The experimental results are still being analyzed and will be published as a article in the future.2.Part of the microcosm exposure experiments was completed.(1)Established experimental microcosm: Seven microorganisms were used to form the microcosms with basic material cycle functions;(2)Completed the two-species food chain exposure experiments: The effect of microplastic on Chlorella and Daphnia were investigated in the microcosms.3.3 international conference presentations have been given, and 2 papers have been written and one has been submitted.

1.完成了单种暴露实验。(1)完成水蚤的暴露实验：结果表明：大鼠可摄取密度高于水的MP颗粒；(2)完成斑马鱼暴露实验：实验结果仍在分析中，后续将以文章形式发表。完成了部分微观暴露实验。(1)建立实验微观环境：采用7种微生物形成具有基本物质循环功能的微观环境；(2)完成两种物种食物链暴露实验：在微观环境中研究微塑料对小球藻和水蚤的影响。参加国际会议3.3次，撰写论文2篇，投稿1篇。
