| Abstract | Microplastics (MPs) contamination in water supply sources is presently an important ecological problem due to they are able to move through the food chain and accumulate in living organisms, they might contain harmful contaminants on their surfaces and become a secondary source of contaminants. This study investigated the contaminated MPs in three water supply sourcesPa Ton, Pa Daet, and U-Mong water supply stations in Chiang Mai province, Thailand. Sampling and analysis referenced the National Oceanic and Atmospheric Administration (NOAA) method using plankton nets. The results showed the average number of MPs at these three sites were 3,880 ? 1,150, 3,810 ? 1,355 and 3,320 ? 628 pieces/m3 , respectively, The MP types were polyester, polyurethane, nylon, polyethylene, polyethylene terephthalate and polypropylene observed by microscope and Fourier-transform infrared spectroscopy (FT-IR). Further, there were the positive correlation between the number of MPs and the physical water parameters (Total Suspended Solid) at the 0.05 level of probability. This is the fi rst scientifi c report that investigates MP contamination in the water supply sources in Chiang Mai province. The fi ndings are knowledgeable and fruitful for environmental concern regarding MPs contamination in water supply sources. |
