Microplastic Contamination Determination on Selected Major Water Bodies of the Philippines Alvin Angelo A. Salting January 11, 2018 January 11, 2021 The study aims to determine the extent of microplastic contamination in the selected major water bodies of the Philippines, specifically to identify and correlate the amount of microplastic contamination across the following – major water bodies, near-shore and off-shore and across water column.

Initial results showed moderate to high positive correlation between microplastic data (Davao Gulf) and the secondary data from the Environmental Management Bureau (EMB) and Department of Tourism (DOT). An outcome of moderate to high positive correlation suggesting these secondary data is relative with the level of microplastic contaminants. Meaning, there is significant impact of the visitors’ arrival gathered from DOT and the water quality data gathered from EMB.

Enhancing Resilience of Wetlands and Coastal Areas for Disaster-Risk Reduction and Mitigation
Project 3. Development of Mangrovetum for Biodiversity Conservation Towards Ecotourism Carlito R. Buante Jan. 2, 2017 Dec. 31, 2020 Mangrove ecosystems have been managed unsustainably as a result of indiscriminate cutting of trees, land use conversion, and overexploitation causing a destruction of the habitat; diminishing fish population; decreasing volumes of shells, crustaceans, and mollusks; loss of breeding and nursery grounds for marine resources; and siltation of estuaries and inland waters. This study aims to develop mangrovetum areas in support to biodiversity conservation and nature-based tourism in partnership with people’s organizations and communities.

The experiment is being implemented in three strategic locations in the Visayas, to wit: (a) Ivisan, Capiz for Western Visayas; (b) Olango Island, Cebu for Central Visayas; and (c) Calbiga, Samar for Eastern Visayas. Most of the planted mangroves have already attained the flowering stage. Some mangrove species were able to bear fruits and mature propagules and seeds. The phenological characteristics of mangroves are being monitored to obtained new information and update the Mangrove Seed Calendar. Some of the mangrove species have been developing peculiar root systems distinct to each species, which are their means of adaptive capacity to thrive in very harsh site conditions. For instance, the Rhizophora group tends to develop stilt or prop roots; pneumatophores for the Avicennia and Sonneratia group; while the Bruguiera and Ceriops group develops knee roots. The activities are focusing on growth data collection for estimating biomass yield and carbon sequestration, monitoring of the development of matured fruits/ propagules for seed germination and viability testing, and preparation of management plans for future undertakings in collaboration with the people’s organizations such as development of a mangrove ecotourism park, seed sources, and the like.

Project 5. Microplastic Contamination on Selected Major Water Bodies of the Philippines Jon Alfonso P. Horvidalla
Alvin Angelo A. Salting
Sept. 11, 2018 Sept. 10, 2021 Considering that the major islands of the Philippines are now being interconnected by ports of call and number of ships and fast craft ferries are now accommodating passengers across these islands, plastic wastes are now prevalent and highly observable on every port in the region. Passengers also contribute to this improper waste disposal in the open ocean by throwing away plastic wastes overboard. Thus, this collaborative study between ARDEC and CRERDEC is conceptualized to determine the extent of plastic waste contamination – particularly microplastics in some marine water bodies of the Philippines including Boracay Island, Guimaras, and Tañon Strait Filtration of water samples and the analysis of filtered samples using a dissecting microscope with motic imaging software of SEAFDEC/AQD were continued. The samples were collected from Guimaras Island/Strait last December 2019. As of 12 March 2002, 252 out of 294 samples were already analyzed. Microplastics such as fragments, foam, fibers, and nurdles were observed in the filtered samples. For the Luzon sites, microscopic analysis for the Subic and Lamon Bay dry and wet season samples was completed at ERDB Laboratory. Data analyses, both descriptive and inferential statistics, are underway, as well as, the processing of water samples collected from the Manila Bay area. The partial results showed that microplastics are present in the Visayas Region and are well distributed across the water column. The presence of microplastic in the marine water bodies in the Visayas may have health effects to the organisms and can be bioamplified up to level of humans by consuming fishery resources with microplastics in the tissues and gut. Initiatives the monitors the microplastic in the major marine water bodies and organisms important to fishery are suggested.
