Keywords:Shakujii River, microplastic, COD, nitrogen compound, phosphorus

We investigated microplastic contamination and concentration of phosphorus and multiple nitrogen compounds in the familiar Shakujii River. There are four survey sites: "Sumidagawa Confluence Area", "Johoku Central Park", "Shakujii Pond", and "Koganei Mukodaicho".The survey items are the content of microplastic concentration and concentration of COD, ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, and phosphorus. For microplastics, river water was strained using a sieve, and the number of microplastic particles was measured using a microscope. We will consider how these are related based on the environment at each point.
