Introduction
Once acknowledged as innovations, plastics are now ubiquitous in daily life, but they have serious unintended consequences. Plastics and their additives are making their way into the environment and, concerningly, the human body through a variety of products, including packaging, textiles, and cosmetics. This lesson examines the ways in which micro- and nanoplastics can enter the body through the skin, food, airways, and even during pregnancy. From endocrine disruption to neurological and cardiovascular disorders, it explores the toxicological effects associated with plastic particles and chemical additives.
Plastic sources, such as textiles and cosmetics, are given special attention because they are frequently disregarded but have a substantial exposure. Health risks are further increased by plastics’ bioaccumulative nature and persistence in the environment. To create safer materials and sustainable technologies, engineering students need to comprehend this systemic issue. The problem is now profoundly human in nature rather than just environmental. In order to rethink the plastic lifecycle, engineers are essential.
Reducing the negative health effects of plastic pollution requires responsible design and circular thinking.

Lesson Learning Outcomes
After completion of this lesson, learners will be able to:
Recall information focusing on plastics’ impact on environment and human health
- They will identify common sources of plastic and micro(nano)plastic waste that contribute to environmental pollution and pose some human health risks.
Understand the interdependence between plastic and ecosystems, and consequently with the human health.
- They will explain the health impacts of plastic and micro(nano)plastic waste on human life, including issues related to ingestion, inhalation, and chemical exposure.
- They will describe how long-term accumulation of plastic waste affects ecosystems and, consequently, human life through the food chain and environmental contamination.
Apply the knowledge in practical activities
- They will implement personal and community practices to reduce plastic waste and prevent its release into the environment, such as reducing plastic use, advocating for better industrial practices, using reusable items, participating in clean-up activities, and proper waste sorting.
Analyze practical examples related to plastics and human health correlation
- They will express their critical opinion and transfer developed knowledge and skills to HEI colleagues and the public.
- They will analyze case studies of communities affected by plastic and micro(nano)plastic pollution, identifying the key factors and consequences of such pollution on human health and their living space.
