The Release of Dye and Microplastic-Related Chemicals into Nature by Humans: How Much is Discharged, and What Are Their Global Effects?
(KNU)
oSunghwan Kim
As synthetic dyes and microplastics become increasingly prevalent in industrial and consumer applications, their unintended release into natural environments raises serious concerns. This study examines the extent to which dyes and microplastic-related chemicals are discharged into ecosystems, their degradation pathways, and the associated global environmental effects. Utilizing advanced analytical techniques, including high-resolution mass spectrometry, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry, we assess the degradation products of polyethylene terephthalate, polystyrene and Nylon microplastics and synthetic dyes. Our findings reveal that dyes such as anthraquinone derivatives and microplastic degradation compounds contribute to widespread water pollution, persisting in riverine and marine environments. Toxicity assessments indicate that these compounds can have long-lasting effects on aquatic life, disrupting ecosystems and potentially bioaccumulating in the food chain. The study also highlights regional differences in the composition of chemicals, indicating localized variations in contamination sources. By quantifying these pollutants and evaluating their environmental persistence, this research underscores the urgent need for regulatory policies to mitigate the impact of industrial waste on global water bodies.
