Microplastics in the environment: impact on human health and future mitigation strategies

Plastic is a synthetic material that has gradually been integrated into nearly all aspects of human life because of its malleable and durable nature; it can commonly be found in consumer products such as textiles, beauty products, and food packaging. The massive prevalence of plastic-based items in our society poses a potential threat to human health and the environment. Since plastic material can physically degrade over time, there is growing concern over the production of microplastics (MPs), which are plastic particles that are ≤5 mm in size. Recent studies confirming the presence of MPs in our environment and drinking water have garnered significant attention worldwide because of the potential impact on human health. As a result of growing public concerns, legislative action has been taken in Canada to ban the manufacture and importation of personal care products containing microbeads. MPs are a new and upcoming issue that the environmental public health field should monitor. In the future, we may play a major role in educating the public on what microplastics are and their impact on our health in addition to consulting stakeholders as regulations get implemented.
