Microplastics are taking over our space and how. There is ample scientific evidence to show that microplastics have been found in almost every organ of the body, including the heart, brain, lungs, kidneys, and even the placenta.

The health risks of microplastics in our systems aren’t just linked to various diseases. A new study has found that these tiny plastics present in the air are linked to lung and stomach cancer.

Tiny plastic particles from tires and degraded plastic waste are becoming a significant concern for air pollution, according to a recent study led by researchers at the University of California, San Francisco (UCSF). May be associated with serious health risks.

These microplastics, smaller than a grain of rice, are now being found in the air we breathe, raising concerns about their impact on respiratory and overall health.

The study published in Environmental Science & Technology reviewed nearly 3,000 research papers and identified potential links between airborne microplastics and health conditions such as infertility, colon cancer, poor lung function and chronic pulmonary inflammation.

These tiny particles can penetrate deep into the lung tissue and create an environment conducive to DNA damage and cell mutation, both of which are major factors in the development of cancer.

How do microplastics enter the air?

Every year, approximately 460 million metric tons of plastic are produced globally, and this number is expected to double by 2050. A major source of airborne microplastics is tire and road wear caused by friction while driving. Over time, these particles enter the air, and impact human health.

Dr. Tracy J., senior author of the study and director of UCSF’s Program on Reproductive Health and the Environment (PRHE). Woodruff said microplastics particles act like air pollution, which is already known to cause serious health problems.

Dr Pooja Babbar, consultant in medical oncology at CK Birla Hospital, Gurugram, commented on the study and highlighted that inhaled microplastics can penetrate deep into the lung tissue, causing chronic inflammation and oxidative stress.

These conditions create a favorable environment for cell mutation, potentially leading to lung cancer.

On the other hand, ingested microplastics can disturb the gut microbiome, trigger local inflammation and increase the risk of colon cancer. Additionally, chemicals such as bisphenol A and phthalates, commonly found in plastics, can disrupt endocrine functions and promote tumor growth.

While more research is needed to establish a definitive causal relationship between microplastics and diseases such as cancer, scientists agree that the existing evidence demands immediate action.

Nicolas Chartres, lead author of the study, urged policymakers to address the health risks of microplastics through better regulation and preventive measures.

What can be done?

Experts suggest reducing plastic pollution by improving recycling methods, eliminating single-use plastics, and increasing public awareness about microplastic exposure.

Reducing personal exposure through masks in polluted areas and reducing plastic consumption can also play an important role.

The researchers said microplastic pollution is no longer just an environmental problem, it is an emerging public health crisis that requires global cooperation.
