Scientists have determined that microplastics, which are plastics smaller than 5 millimeters in size, can be found in our food, water, and air. These particles contain harmful chemicals that can disrupt our body’s natural processes and increase the risk of reproductive disorders and certain cancers. In a recent study published in Environmental Science & Technology, researchers from Cornell University examined data from around the world to determine which countries had the highest exposure to microplastics through ingestion and inhalation. Factors influencing exposure include dietary habits, economic support for monitoring and limiting microplastics, industrialization rates, and waste generation.
Countries in Southeast Asia such as Indonesia, Malaysia, and the Philippines were found to have the highest dietary intake of microplastics, with Indonesians consuming about 15 grams of microplastics per month. The highest inhalation rates were observed in Mongolia and China, with citizens inhaling over 2.8 million microplastic particles per month. In comparison, the United States had a lower level of microplastic exposure, with dietary intake at roughly 2.4 grams per month and inhalation of 10,500 particles per month. However, there is still concern for potential increased exposure as plastic use rises, highlighting the importance of implementing advanced waste recycling and water management processes.
To minimize microplastic ingestion, experts recommend using non-plastic reusable materials, such as glass and metal containers, during food processing, storage, and consumption. Despite efforts to reduce exposure, the full extent of health risks associated with microplastics remains unclear, and further research is needed to understand the potential threats to human health.
