Microbeads, small plastic particles used in personal care products, are of great concern because they are not effectively filtered out during wastewater treatment processes, leading to their release into aquatic environments. Once in the ocean, these microbeads can be ingested by marine organisms, introducing toxins into the food chain and disrupting marine ecosystems. This is significant in the context of ecosystem health and biodiversity, as the accumulation of microplastics can lead to harmful effects not only on marine life but also on human health through seafood consumption.
