Sažetak
Microplastics (MPs) are omnipresent in our environment, from soils and oceans, and in food chains – thus leading to their accumulation in our day-to-day consumable products1. Drinking water is one of the primary sources of human exposure to microplastics. Currently we are investigating the presence of the MPs in tap-water collected from pipelines across city of Zagreb. The collected samples were filtered through Si-filters or TEM grids and the deposited particles were systematically analysed by Raman spectroscopy. Water samples were treated with EDTA-Na4 solution2 by facilitating the formation of the soluble EDTA-M2+chelates when relatively large quantities of the inorganic particles particularly alkaline carbonates (M2+CO3) were present. In this way one achieves the deposition of larger MPs to inorganic particles ratio on the filter which increases the efficiency of detection of the MPs. Raman micro-spectroscopy was used as primary tool for the analysis of MPs deposited on the filters. Findings related to microplastic concentrations, particle count, polymer types and particle size distribution (particularly ≤ 100 μm) are reported.
