You will not believe how many tiny plastic particles plastic-coated paper cups can release when exposed to tea, coffee for just 15 minutes

Microplastics are minute particles made out of plastics that have embedded themselves in our natural environment. Their interaction with human’s biological ecosystem is under scrutiny, said Dr Mridul Malhotra, consultant, medical oncology, Manipal Hospital Dwarka, New Delhi.

Dr Malhotra said that microplastics may contribute to carcinogens via various routes:

– Chemical composition contamination: Microplastics may carry and deliver chemicals containing carcinogens to the tissues in the human body.
– Inflammation: Microplastics can induce cellular changes that can lead to cancer in the body.
– Disrupting the mucus layer: Microplastics can disrupt the mucus layer, particularly of the gastrointestinal tract, and further compromise the protective barriers of the human body.

It is also a fact that when any hot beverage is served in a paper cup, some substances may get absorbed into the beverage, raising concerns about prolonged exposure over time, which can impact one’s well-being in the long run, asserted Dr Kaushik. “It’s important to note that current research hasn’t definitively proven that the occasional use of paper cups causes cancer. There is no evidence available to back up this claim,” said Dr Kaushik.

Citing an August 2024 study, Dr Malhotra said that exposure to hot liquids in plastic-coated paper cups for just 15 minutes can release approximately 25,000 tiny plastic particles. “Individuals drinking near to three cups of hot beverages in their daily routine may ingest around 75,000 invisible plastic particles,” said Dr Malhotra.

The pros of paper cups include convenience and lightweight design. “The disadvantages would be that the cups may contain chemicals that can raise environmental concerns from single-use waste. For safer use, opt for paper cups labeled BPA-free and consider using reusable alternatives like ceramic cups to minimise exposure and environmental impact,” said Dr Kaushik.

According to Dr Malhotra, there are a few precautionary measures to avoid microplastics in food:

– Using glass or stainless steel vessels
– Avoiding food to be heated in plastic containers
– Choosing microwave-safe containers
– Reducing single-use plastics
– Drinking water from filtered sources

The medical and scientific community is actively researching the impact of microplastics. “Recent studies indicate the potential risks and the need for long-term research to establish definitive causal relationships,” said Dr Malhotra.
