A recent study has found that using a dishwasher with plastic items can release toxic microplastics into water, which may raise the risk of dementia. The researchers discovered that mechanical dishwashing of plastic plates, bowls, cups, and cutlery leads to the release of micro- and nano-sized particles.
The team collected 13 different plastic items and simulated typical dishwasher cycles to assess how much plastic is shed into the water. They found that a single dishwasher cycle can release nearly a million particles. The researchers estimate that six milligrams of microplastics accumulate in the human body per year, which is roughly a quarter of a grain of rice.
While the results may seem alarming, study author Dr. Elvis Okoffo said that the total mass released from plastic containers is low and minor compared to other known sources of plastic pollution. However, the study highlights the potential risks associated with microplastics, which have been linked to dementia, cancer, heart disease, and fertility issues.
The researchers also found that microplastics were present in the brains of deceased individuals studied, including parts of the brain responsible for processing smells and relayed information to other parts of the brain. This suggests that breathing indoor environments may be a major source of plastic pollution in the brain.
As the number of people living with Alzheimer’s dementia is projected to rise significantly by 2030 and 2040, it is essential to consider the potential impact of microplastics on human health. The study serves as a reminder of the need for further research into the effects of microplastics on human cognition and overall well-being.
