Why in the news?

The National Green Tribunal has given the Central Pollution Control Board eight weeks to submit a progress report on developing a uniform national methodology for sampling, preparation and identification of microplastics in water, soil, air, waste and biota. This standardised testing framework is needed to reliably assess microplastic contamination across India, following media reports of microplastics found in Indian salt, sugar and human blood.

Summary

  • National Green Tribunal (NGT) directs Central Pollution Control Board (CPCB) to develop a standardised national methodology for microplastics testing across environmental media.
  • The methodology will cover sampling, preparation and identification of microplastics in water, soil, air, waste and biota.
  • CPCB was given eight weeks to submit a progress report; next hearing on 4 February 2027.

Highlights

  • NGT Directive to CPCB

    NGT grants CPCB eight weeks to report progress on a uniform national methodology for microplastics testing across environmental matrices.

  • Standardised Testing Need

    A consistent testing protocol is required for water, soil, air, waste and biota to reliably detect and measure microplastic contamination nationwide.

  • Context: Microplastics in Food & Blood

    The case was triggered by media reports of microplastics found in Indian salt, sugar brands and human blood samples.

Background

Microplastics (plastic particles <5 mm) are an emerging environmental and public health concern. In India, studies have found microplastics in table salt, sugar, bottled water, and even human blood. However, there is no nationally standardised protocol for sampling, sample preparation, and identification across different environmental media (water, soil, air, waste, biota). This makes inter-study comparisons unreliable and hampers regulatory action.

Key Analysis and Impact

The NGT's directive pushes CPCB to create a unified, scientifically robust testing framework. Once developed and implemented, this methodology will enable consistent monitoring of microplastic pollution across states. It will also support evidence-based policy for plastic waste management, extended producer responsibility (EPR), and potential health advisories. The standardisation across multiple laboratories is a key technical challenge that CPCB must address.

Way Forward

CPCB must submit its progress report within eight weeks. The next NGT hearing is on 4 February 2027. If the methodology is approved, it could be rolled out to state pollution control boards and accredited laboratories nationwide. This will strengthen India's compliance with global frameworks like the UN's ongoing negotiations for a legally binding treaty on plastic pollution.

Background GK

Textbook concepts you need to understand this news

National Green Tribunal (NGT)
A specialised statutory body established under the National Green Tribunal Act, 2010 for effective and expeditious disposal of cases relating to environmental protection and conservation of forests and other natural resources.
Central Pollution Control Board (CPCB)
A statutory organisation under the Ministry of Environment, Forest and Climate Change (MoEFCC), constituted under the Water (Prevention and Control of Pollution) Act, 1974, responsible for pollution control and environmental quality monitoring at the national level.
Microplastics
Small plastic particles less than 5 mm in diameter, which can be primary (manufactured small) or secondary (fragmented from larger plastic items). They are persistent pollutants that can enter food chains and human bodies.

How exams will ask this

  • Data: 8 weeks deadline for CPCB report; next hearing on 4 February 2027
  • Nodal Body: Central Pollution Control Board (CPCB) under Ministry of Environment, Forest and Climate Change
  • Legal Point: National Green Tribunal Act, 2010

Don't make this mistake!

The trap will be to confuse CPCB with state pollution control boards (SPCBs) or to swap the NGT (tribunal) with the Supreme Court or a High Court. Also, 'microplastics' may be confused with 'nanoplastics' (even smaller) or 'bioplastics' (a different category).
