A dataset of 890 microplastics collected from the surface water of Laguna de Bay, Philippines in August and September 2018. Microplastics were collected in 3 sites of the bay: 1) Brgy. Napindan, Taguig City, Metro Manila; 2) Brgy. San Isidro, Tanay, Rizal; and 3.) Brgy. Sampiruhan, Calamba Laguna. The dataset contains the the ID of each microplastic fragment, collection month, site, sampling point, length (in micrometers), roundness score, and CIE color coordinates (L*, a*, and b*). The survey was done to assess the properties (length, roundness and color) of the microplastics in Laguna de Bay.


Steps to reproduce

The 890 microplastics in this dataset is from 909 plastic fragments collected by sieving surface water (500 L August visit; 2000 L September visit). The length and roundness of the microplastics were measured by image analysis using ImageJ. The color coordinates CIE L*, a* and b* were obtained also by image analysis using the 'colordistance' package in R.
