Abstract:
The net use of plastic has increased and this augmentation in plastic usage results in ever- growing accumulation of plastic waste in our ecosystems. Regrettably, a portion of this waste is the microplastics including microbeads, which are tiny plastic particles <5 mm in diameter. Microbeads are used in our personal care products. Although, legislative ban of microbeads in some developed countries has proven effective, but many countries do not take any legal action. Hence, microbead-containing products are openly sold in international market and entered into the food chain and disturb it. In human beings and animals, plastic when ingested causes internal bleeding, abrasion, ulcers and blockage of the digestive tract. The present review highlighted the bioaccumulation of microbeads via the food chain and its adverse effect on environment health. Moreover, different scientific views and suggestions for eradication of the problem and present scenario of the use of microbeads in some Asian countries have also been discussed.
Insights
Microbeads, tiny plastic particles from personal care products, are entering the food chain, posing risks to wildlife and human health. This review examines their environmental impact and discusses solutions.
Area of Science:
- Environmental Science
- Ecotoxicology
- Public Health
Background:
- Increasing global plastic use leads to escalating plastic waste accumulation in ecosystems.
- Microplastics, including microbeads (<5 mm), are prevalent in personal care products and enter the environment.
- Despite bans in some nations, microbead-containing products remain available internationally, contaminating food chains.
Purpose of the Study:
- To review the bioaccumulation of microbeads through the food chain.
- To highlight the adverse effects of microbeads on environmental and human health.
- To discuss scientific perspectives on microbead eradication and their current use in Asian countries.
Main Methods:
- Literature review of scientific studies on microbead pollution.
- Analysis of environmental and health impacts of ingested microplastics.
- Examination of legislative actions and current usage patterns in Asian nations.
Main Results:
- Microbeads are bioaccumulating in organisms via the food chain.
- Ingested plastics can cause severe internal health issues in animals and humans.
- Varied regulatory approaches exist globally, with continued use in many regions, particularly in Asia.
Conclusions:
- Urgent global action is needed to curb microbead pollution.
- Effective strategies include legislative bans and the development of sustainable alternatives.
- Further research is essential to understand and mitigate the long-term ecological and health consequences.
