Infographic “Microplastics in the Environment”: Two Decades of Discoveries and Challenges
The TERRA Associate Laboratory has released a new infographic titled “Microplastics in the Environment: Two Decades of Discoveries and Challenges”, an essential resource for understanding the origin, dispersion, and impact of microplastics on ecosystems and human health.
Microplastics—defined as plastic particles smaller than 5 mm—were first documented in the oceans during the 1960s, and their presence in the environment has increased alarmingly ever since. Recent studies, such as one conducted by scientists from the Faculty of Sciences of the University of Porto (Notícias UP, March 5, 2025), reveal concerning levels of microplastics in the air in Porto, underscoring the ubiquity of this invisible pollutant.
Microplastic pollution originates from various sources, including industrial and agricultural activities, as well as the everyday use of cosmetic and textile products. Its impact is extensive, affecting over 1,300 marine and terrestrial species, and microplastics have been found in drinking water, food, and even in the air we breathe. As highlighted in a recent guide published by SIC Notícias (March 9, 2025), the risks to human health are becoming increasingly evident, with potential toxic effects and bioaccumulation risks throughout the food chain.
The new infographic by TERRA, authored by researcher Filipa Bessa from CFE, synthesizes the main scientific findings on this issue. It warns that even if microplastic emissions were halted today, environmental accumulation would continue due to the ongoing fragmentation of existing plastics. The document also stresses the urgent need for further research on ecological impacts and the development of effective strategies to mitigate this form of pollution.
TERRA Associate Laboratory reaffirms its commitment to scientific research and public outreach, promoting accessible knowledge so that both society and policymakers can act in an informed manner.
The infographic is now available for consultation on the TERRA website.
