Abstract

Microplastics are plastic particles with a size of 1 μm – 5 mm that are widely present in surface water and sediments. Increased exposure to microplastics in water can affect food chain cycles, leading to bioaccumulation and biomagnification in fish. This study aims to analyze the abundance, types, and polymer types of microplastics in surface water and fish in the Air Hitam River, Pekanbaru City, Riau. Air Hitam River is one of the tributaries of Siak River which has a length of ±8,5 km. Determination of sampling locations for each segment using purposive sampling method based on existing conditions along the river flow by identifying sources of microplastic pollution. The results showed that the average abundance of microplastics in the waters of Air Hitam River was 330±150,3 particles/L. The average abundance of microplastics in 8 Chitala lopis was 0,86±0,24 particles/gram for meat samples and 4,35±0,4 particles/gram for gill and digestive tract samples. The types of microplastics found in this study are fragments, fibers, films, and pellets. The results of the Pearson Product Moment correlation analysis showed that there was a significant relationship between aquatic environmental parameters (temperature, pH, and flow velocity) and the abundance of microplastics in the Air Hitam River with a sig value. (0,005 < α 0,05) for temperature parameter, sig. (0,215 > α 0,05) for the pH parameter, and sig. (0,248 > α 0,05) for the flow velocity parameter. The polymer types identified based on the Differential Scanning Calorimetry (DSC) test results are Polycarbonate (PC) and Polypropylene (PP).

Abstract

Tenayan Industrial Estate has various anthropogenic activities, including industrial and population-related activities. Many activities can affect the levels of pollutants in the air, including microplastics. Microplastics can be transported through the air by meteorological factors. This research examined the abundance of microplastic particles in ambient air around the Tenayan Industrial Estate, focusing on the types and kinds of microplastic polymers. The air sampling method employed was passive sampling, conducted at three locations: upwind, downwind, and center, carried out every 7 days for 28 days. Microscopical method to determine the amount of abundance, the classification of microplastic polymer types and types. Differential Scanning Calorimetry (DSC) tests were conducted to determine the type of plastic. The research results show that the upwind point has an average weekly microplastic abundance of 64.00 ± 39.53 particles/liter. The central point is the average abundance of 69,5 ± 31,38 particles/liter. The downwind point has the highest average microplastic abundance of 81 ± 60,86 particles/liter. The dominant form of microplastics is fiber, accounting for 60,7%. The Microplastic polymer types identified are polyvinyl chloride, polycarbonate, and polyamide. The results showed that microplastic abundance was influenced by meteorological factors, specifically wind speed. Downwind locations, which are residential areas, have the highest microplastic abundance, indicating accumulation rather than directional transport.
