Summary
Microplastics (MPs) have complex surface chemistry influenced by environmental factors. Wastewater treatment plants are key accumulation sites, highlighting the need for colloid science in MP mitigation.
Area of Science:
- Environmental Science
- Colloid and Interfacial Science
- Polymer Science
Background:
- Microplastics (MPs) are <1 mm plastic particles from production or degradation.
- Their small size makes interfacial properties critical to environmental behavior.
- Environmental stressors significantly alter MP surface chemistry.
Purpose of the Study:
- To highlight the complex surface chemistry of MPs under environmental stressors.
- To discuss how physical attributes (shape, roughness) influence MP fate.
- To identify wastewater treatment plants (WWTPs) as MP accumulation hotspots.
Main Methods:
- Literature review and perspective synthesis.
- Analysis of interfacial properties and surface chemistry.
- Identification of MP fate in environmental systems.
Main Results:
- MP surface chemistry is complex and affected by environmental conditions.
- Physical attributes like shape and roughness impact MP environmental fate.
- WWTPs are significant hotspots for MP accumulation and transfer via sewage sludge.
Conclusions:
- Colloid and interfacial science is crucial for understanding MPs.
- Advanced understanding can inform mitigation strategies in WWTPs.
- Addressing MP accumulation in WWTPs is vital for environmental protection.

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...
