Opinions of parents and parents-to-be on micro- and nanoplastics: knowledge and willingness to implement change in Canada
Summary
Researchers surveyed 300 expecting parents and parents of young children in Canada about their knowledge of microplastics and nanoplastics and their willingness to reduce plastic use. While 79% were aware of micro/nanoplastics and 75% understood their environmental impact, knowledge of specific household exposure sources and health effects was lower, suggesting targeted education could drive behavior change.
Macroplastics (and their degradation products) have been known to have an impact on the ocean and land environment for over 50 years. With the discovery of microplastics and nanoplastics in the human body, recent attention has focused on their potential health effects. Here, a survey was used to gauge the current state of knowledge about microplastics and nanoplastics and willingness to consider plastics-reduction actions in 300 expecting parents and/or parents/guardians of young children in Canada. In total, 79% of participants reported knowing what microplastics and nanoplastics are and 75% were aware of their significant impact on the environment. In contrast, knowledge of potential sources of human exposure to plastics (e.g., household products, food, drinking water) and knowledge about recent preclinical research findings was low. The majority of participants (98%) were willing to consider making at least one change to their homes or daily habits to reduce plastics exposure and participants who reported knowledge about microplastics and nanoplastics were more likely to consider multiple changes in behaviour. To facilitate environmental action, strategies (e.g., email communication, blog, documentaries, social media posts) are needed to improve public knowledge about the potential human health effects associated with microplastics and nanoplastics.
