Description
Summary:Microplastics are considered as one of the most widespread environmental pollutants. The undertaken study presents an analysis of microplastics polymer in tea, powder milk and tea whitener in Wah Cantt Pakistan. Twenty-three samples of local and branded tea, powder milk and tea whitener were analyzed. Samples were examined via FTIR and SEM-EDX to detect presence of microplastics polymer. FTIR spectra of all samples revealed presence of various microplastic such as polyethylene, polyethylene terephthalate, polyvinyl alcohol, polystyrene, nylon, along with other toxic contaminants such as chromium hydroxide, phosphorus, polyamide. Moreover, SEM images show irregular, rod shape, fragments, thread like structure which were commonly observed in microplastics. The EDX spectra have further authenticated SEM results as it has shown carbon dominant peaks which are common attributes of microplastics polymers. Comparatively, local samples are more contaminated compared to branded samples. The microplastics polymers found in tea ingredients are reportedly highly toxic and capable of damaging nervous system, immune system, hormonal imbalances and causing cancer. The study recommends that use of plastic should be minimized particularly for packaging of tea, powder milk and tea whitener.
