Researcher warns of alarming consequences of city nightlife: 'People need to be aware'

A resident of Derby, U.K., has raised concerns about the growing problem of microplastic pollution, urging locals to refrain from discarding plastic waste during nights out. Onyinye Nketa, who conducted research on microplastics during her postgraduate studies at the University of Derby, emphasizes the importance of proper waste management in the city center.

In an article for Central Bylines, Nketa highlighted that single-use plastics, such as discarded food containers, frequently litter the streets after patrons leave bars and restaurants. Over time, these plastics break down as people walk or drive over them, eventually entering local waterways. Her Masters research, which focused on the River Derwent, revealed that the highest concentrations of microplastics are located near Derbys city center.

Microplastics have already infiltrated water, soil, air, and food, making human exposure unavoidable. One study found these particles in 90% of protein samples, including beef, chicken, and tofu. Once ingested or inhaled, microplastics can accumulate in the body. Although research is ongoing, these tiny plastics have been associated with health issues such as cancer, dementia, and impaired cerebral blood flow.

Nketa also warns that microplastics eventually reach the ocean, posing risks to marine life. According to the Plastic Pollution Coalition, marine animals such as corals, fish, seabirds, sea turtles, and zooplankton can suffer severe health effects or death from consuming microplastics.

She encourages Derby residents to be more conscientious with their plastic use during nights out. "People should learn to properly dispose of their rubbish in all circumstances," Nketa said. She also suggests that bars, clubs, and restaurants provide smaller bins closer to venues and consider designating staff to regularly clear waste, maintaining a cleaner environment.

Reducing single-use plastics is another effective way to curb microplastic pollution. Reusable alternatives such as takeout containers and grocery tote bags can significantly decrease plastic waste.

Scientists are also exploring methods to remove existing microplastics from water. For example, some research teams are using natural coagulants derived from chickpeas and tree seeds, while others experiment with egg whites to extract microplastic particles from water.
