Blink:
Back in June I posted Eureka which detailed an innovative solution to filter out microplastics in washing machines, a major source for microplastic pollution. Writing the post opened my eyes to the ubiquity of microplastics. Today I want to share some relevant learning.
Read On:
- Several scientific papers have been published in the past few years detailing how microplastic fibers from our synthetic clothing are released during our household washing. It depends on the type of synthetic garment (e.g., polyester) and weight. Other factors contribute to pollution such as detergents, water temperature, and length of wash cycle. An alarming number given synthetic now comprise two-thirds of all fabrics produced each year and as many as of 1.5 million fibers can be released from a single washing per week. Imagine all these fibers flowing into waterways via washing machines making them the primary source of microplastics pollution.
- Being in the food business, I decided to learn more about microplastic pollution in food. The University of Amsterdam just published a study summarizing the data from close to two hundred research papers. For years I assumed seafood contained a high concentration of microplastics. A microplastic particle is less than 5 millimeters in size, thinner than a human hair, and finer than a grain of salt. Researchers have now found microplastics in every food category, specially produce and grains which grow in agricultural soil – a long-term sink for microplastics via numerous pathways. Health related concerns are still being analyzed when they breakdown into smaller particles as they enter our body’s tissues and organs.
- I am enduring the heat wave here in France. Every time I observe people carting six-liter packs of bottled water, I can only wonder how much microplastics do they consume per day. Research has indicated thousands to hundred of thousands of smaller particles, nanoplastics per liter mainly, shed from the bottle itself, the cap, or the manufacturing and distribution of the bottled water.
The pervasiveness of microplastics since I read about the potential of washing machine filters will help mitigate its pollution has piqued my interest since the beginning of the summer. Candidly I am concerned the more I research the topic. I am also anxious about the amount which I might consume day in and day out when I take my morning swim in the Mediterranean. A small amount of water does enter my mouth (obviously I do not swallow) and I do drink my fair share of bottled water to stay hydrated during this heat wave.
