Summary
Nanoparticles (NPs) offer benefits but pose nano pollution risks. Airborne NP exposure is linked to serious human diseases, necessitating further research for safety solutions.
Area of Science:
- Nanotechnology and Environmental Science
- Toxicology and Public Health
Background:
- Nanomaterials, based on nanoparticles (NPs) (1-100 nm), have broad applications since the 1980s.
- Increasing use of nanomaterials has led to significant environmental concerns, termed 'nano pollution'.
- The unique properties of NPs drive their adverse effects on ecosystems and organisms.
Purpose of the Study:
- To review the types and applications of nanoparticles (NPs).
- To examine airborne NP pollution, including engineered (ENPs) and non-engineered (NENPs) sources.
- To explore the link between airborne NP exposure and human health issues.
Main Methods:
- Literature review on nanoparticle applications and pollution.
- Analysis of NP sources, categorizing into engineered and non-engineered (natural and anthropogenic).
- Synthesis of studies correlating airborne NP exposure with human diseases.
Main Results:
- Nanoparticles are integral to various industries, from medicine to consumer goods.
- Airborne NP pollution stems from both engineered and non-engineered sources.
- Exposure to airborne NPs is associated with respiratory, cardiovascular, and neurological disorders.
Conclusions:
- Understanding NP pollution hazards and impact mechanisms requires extensive research.
- Addressing NP pollution is crucial for protecting human health and environmental quality.
- Developing effective solutions for NP pollution is essential for public safety.
