Seafood Microplastic Contamination Increases Human Health Risks
Human consumption of seafood contaminated with microplastics poses potential physical and chemical health risks due to widespread environmental pollution.
Current Environmental Health Reports · 2018
Key Findings
- 01Microplastics are widespread in marine environments due to human activities.
- 02Seafood, particularly shellfish consumed whole, is a significant pathway for human exposure to microplastics.
- 03Potential health effects are linked to dose, polymer type, size, surface chemistry, and hydrophobicity of microplastics, as well as associated chemicals.
- 04There is an urgent need for more research on microplastic toxicity and epidemiology in humans.
Application
Design takeaway
Minimize the use of non-biodegradable plastics in products and packaging that could end up in marine environments, as these can contaminate the food chain and pose risks to human health.
How to apply
When designing products, especially those related to food or marine activities, consider the materials used and their potential to break down into microplastics. Opt for sustainable alternatives and design for easy disassembly and recycling.
Project actions
- 01Investigate the lifecycle of plastics used in your product and how they might enter the environment.
- 02Explore alternative materials that are biodegradable or have a lower environmental impact.
- 03Consider the 'end-of-life' scenario for your product and how to prevent it from contributing to pollution.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Synthesizes a broad range of existing research.
- +Identifies critical knowledge gaps and areas for future research.
- +Highlights the importance of seafood as a dietary source and potential exposure route.
Limitations
The exact health impacts are still under investigation, making it difficult to quantify the precise risk. The study relies on existing research, which may have its own limitations.
Reliability & validity
The study's findings are based on a synthesis of multiple research papers, which can increase reliability if the original studies were robust. Validity is supported by the consensus within the scientific community on the issue of microplastic pollution. However, the direct causal link and precise magnitude of human health impacts remain areas requiring further empirical validation.
Think critically
Given the widespread nature of plastic pollution, is it possible for any product to be entirely free from contributing to microplastic issues, or should the focus be on minimizing and managing the inevitable?
Design Principles
"Design for minimal environmental impact throughout the product lifecycle, considering pollution and resource depletion."
This highlights the critical link between resource management, environmental pollution, and human well-being. Designers must consider the full life cycle of products and materials, understanding how their choices can contribute to or mitigate environmental contamination that ultimately affects human health.
What This Means for Your Design
Plastic pollution in the ocean means that fish and shellfish we eat can contain tiny plastic bits, which might be bad for our health.
How to use in your project
- 1.Use this insight to justify material choices, emphasizing the need to avoid materials that contribute to microplastic pollution.
- 2.Incorporate a section on environmental impact assessment, specifically addressing the potential for microplastic generation and its consequences.

Paragraph starter
The pervasive issue of microplastic contamination in marine ecosystems, driven by human activities, presents a significant challenge for resource management and human health. As highlighted by Smith et al. (2018), seafood, particularly shellfish, acts as a vector for microplastic ingestion by humans. This necessitates a design approach that prioritizes materials and production systems minimizing plastic waste and its subsequent entry into the environment, thereby mitigating potential physical and chemical toxicities associated with microplastics and their adsorbed pollutants.
