Microplastics concentration in surface waters along Manila Bay, Philippines from 2018-10-07 to 2019-02-11 (NCEI Accession 0271964)

This study was carried out to estimate the microplastics (i.e. plastics measuring less than 5mm, reported in unit of pieces/m^3) concentration in surface waters along Manila Bay, Philippines from 2018-10-07 to 2019-02-11. A metallic bucket was used to collect water from 0 to 12 cm below the surface water. Water from the bucket was poured unto stacked stainless sieves with varying mesh sizes. Microplastics were identified and counted under a stereo microscope. This dataset contains the results from all 5 sampling stations, in a spreadsheet format.

Processing Steps
  • Parameter or Variable: MICROPLASTIC CONCENTRATION (measured); Units: pieces/m3; Observation Category: in situ; Sampling Instrument: Surface water intake; Sampling and Analyzing Method: This study collected samples from October 2018 to February 2019. Sampling was conducted once at each of the five study sites. Water samples of 0.2 m3 with about 5 m away from the riverbanks were collected using a bucket from 0 to 12 cm below the surface of different points in the sampling area. Water from the bucket was poured unto the stacked stainless sieves with mesh sizes of 2.36-mm (No. 8), 1-mm (No. 18), 500-μm (No. 35), 250-μm (No. 60), 125-μm (No. 120) and 75-μm (No. 200). Particles that are greater than 5 mm that were retained from the 2.36-mm sieve were discarded. The used sieves were thoroughly rinsed with distilled water and left to dry for an hour. The retained particles in each sieve were transferred to their respective glass containers using steel tweezers and a brush. To extract microplastics, the samples from the surface waters were oven-dried for 72 h with a temperature of 90°C. The extracted microplastics were examined and photographed using a 3.1-Megapixel CMOS camera connected to a ST-7045 Stereo microscope with magnification of 10x to 40x.; Data Quality Method: In order to confirm the polymeric nature, the samples were analyzed by FTIR spectroscopy (Nicolet 6700 FTIR ATR spectrometer with a diamond accessory). Extracted particles were grouped and representative microplastics in each group of at least 30 particles per site were chosen to test polymer types..
