Abstract
Proposed is a method for estimating the mass of microplastics by using fluorescent staining. The method may include staining microplastic samples by using a Nile red solution, and capturing a fluorescent image of each of the stained microplastic samples after classifying the stained microplastic samples by mass. The method may also include analyzing the captured fluorescent image to quantify a fluorescence intensity thereof to build a database (DB) about a correlation between mass and fluorescence intensity of microplastics. The method may further include estimating a mass value of an unknown microplastic sample by comparing a fluorescence intensity of a fluorescent image of the unknown microplastic sample obtained by performing the staining and capturing of the unknown microplastic sample with data stored in the database.
