| Summary, etc. |
The aim of this study was to determine the prevalence and abundances of MPs in<br/>three mangrove sites across NCR, namely Tanza Marine Tree Park in Navitas city, Baseco<br/>Compound in Port Area, city of Manila, and Las Piñas-Parañaque Wetland Park in Las<br/>Piñas-Parañaque border. In methodology, sediment samples were collected using a<br/>stainless-steel probe. Each sampling site was divided into three transects, seaward (T1), in<br/>between (T2), and landward (T3), and each transect was divided into 4 sample sets by depth<br/>(0-5cm, 6-10cm, 11-15cm, and 16-20cm), where at each depth the researchers collected<br/>100 g of sediments, for a total of 36 sediment sample sets. When it comes to sample<br/>treatment, it is first in-air dried for several days to reduce its moisture content, after drying,<br/>the sediments are sieved using a 0.125 mm stainless-steel mesh to obtain a uniform particle<br/>size distribution suitable for MP isolation. Then it is oven dried at 80°C for 12 hours to<br/>remove the remaining moisture content in the sediments. When it comes to extraction of<br/>MP, it is first soaked in 200 mL of 60% calcium chloride (CaCl2) for the density separation<br/>technique to separate MP particles from the sediments, and filtered using Whatman Grade<br/>1 filter paper with 11μm pore size to filter the MPs from solutions. When it comes to<br/>organic digestion, it is soaked in 10% potassium hydroxide (KOH) solution to remove the<br/>organic matter present in the MPs and filtered again using filter paper to filter the<br/>specimens from the solution. For sample analysis, microscopy analysis was first performed<br/>to determine its physical characteristics such as size, shape, and color. And for the polymer<br/>type identification, the specimens were subjected to Fourier Transform Infrared (FTIR)<br/>spectroscopy to determine the polymer composition of the MPs analyzed. |
