Partial and Temporal Variations in Concentration of Micro Plastic in Drinking Water of Al-Hilla River
Summary
This study measured microplastic concentrations in drinking water from the Al-Hilla River in Iraq, finding contamination across multiple sampling locations and time periods. The presence of microplastics in tap water raises concerns about daily human ingestion through drinking water.
In aquatic ecosystems, a great concern was has been increased about contaminants by microplastics (MPs). Only a small number of researches on contamination of MP in drinking water have been released up until now. In this research, tap drinking water collected in different places in a densely populated region in Al-Hilla city: Al-Bakarly area, Al-Khusrawiya and Al-Tayyara area was analyzed. The collected water samples were tested using different techniques, including Fourier infrared spectrometer (FTIR), Scanning Electron Microscope (SEM) and Micro Raman spectrometer (MRS). Results showed the presence of microplastic particles with that size smaller than 5 mm, as the diameter of the drinking water ranged between (0.5-4.8) nm. The means of Fourier infrared spectrometer (FTIR) was used to analyze component of all found particles chemically. The main components of the tested samples are metal oxides, Poly Vinyl Chloride (PVC), polyamides polymer like Nylon6, 6 and skeletal of cellulose. In addition, Micro-Raman spectroscopy (MRS) results indicated a variation in polyethylene (PE), and it was between (121.404-4391.729) cm -1 for collected samples.
