Microplastics Detected in All Sugar, Salt Brands Samples
The study identified various forms of microplastics, including fibres, pellets, films, and fragments, in all salt and sugar samples. The size of these microplastics ranged from 0.1 mm to 5 mm. Iodised salt was found to have the highest concentration of microplastics, particularly in the form of multi-coloured thin fibres and films.
Ravi Agarwal, founder-director of Toxics Link, told PTI, “The objective of our study was to contribute to the existing scientific database on microplastics so that the global plastic treaty can address this issue in a concrete and focused manner.” He emphasized the need for policy action and research on technological interventions to reduce microplastic exposure risks.
Satish Sinha, associate director of Toxics Link, highlighted the urgency of addressing the issue, saying, “Our study’s finding of substantial amounts of microplastics in all salt and sugar samples is concerning and calls for urgent, comprehensive research into the long-term health impacts of microplastics on human health.”
Findings on Microplastic Concentrations
The concentration of microplastics in salt samples ranged from 6.71 to 89.15 pieces per kilogramme. Iodised salt had the highest concentration at 89.15 pieces per kilogramme, while organic rock salt had the lowest at 6.70 pieces per kilogramme. In sugar samples, the concentration ranged from 11.85 to 68.25 pieces per kilogramme, with non-organic sugar showing the highest levels of microplastics.
Microplastics Become Global Concern
Microplastics have become a growing global concern due to their potential harm to both health and the environment. These tiny plastic particles can enter the human body through food, water, and air. Recent research has detected microplastics in human organs, including the lungs, heart, breast milk, and even in unborn babies.
Salt and Sugar Daily Consumption Risks
Previous studies indicate that the average Indian consumes 10.98 grams of salt and around 10 spoons of sugar daily, which is significantly higher than the World Health Organization‘s recommended limits. The presence of microplastics in such commonly consumed products raises further concerns about potential health risks.
