I am studying the occurrence of microplastics in a river, where the sampling site is too much plastic polluted. Therefore, I have found a high concentration of microplastics in water samples. I am wondering to know the possible highest concentration of microplastics in a polluted water sample which has been recorded till present. It will be helpful for me if anyone suggest me any scientific paper regarding this or any comments on this. Thanks a lot for your time.

All this plastic builds up, and persists, in the Oceans to the detriment of life and ecosystems.

Although it is not possible to know the exact contamination aspect of microplastics, it has been continuously reported to be detected in seawater, fresh water, food, air, and soil. Moreover, it is predicted that the contamination of microplastics will become more serious in the future by several studies. A global estimate of plastic emissions from rivers into the world’s oceans is between 1.15 and 2.41 million tons per year, and most of the river plastic input is coming from Asian countries with rapid economic development and poor waste management [29]. The concentration of microplastics was 250 mg/m3 in 2016 and is expected to be 500 mg/m3 in 2030, and probably exceed 1000 mg/m3, which is four times the 2016 amount, by 2060.

Dear John Machell and Bachir Achour,
Thanks a lot for your comments and valuable information. I will read those papers and study more on this topic. Actually microplastics are big concern nowadays, and a threat for our future days. Best regards - Gourab

I would also like to recommend you this author https://scholar.google.com/citations?user=w7OwiYgAAAAJ&hl=nl. He has done much research on rivers so you probably can find worthwhile information.
Dear Carlos Mazariegos,
Thanks a lot for your answer!!
Kind regards,

This will heavily depend on the physical characteristic of the water. Higher temperatures will have more ability to higher concentrations
Thanks dear Rovshan K Abbasov for this information. Noted!!
I am wondering if you can suggest me any scientific paper to support this statement.
Thanks in advance.
Kind regards.
