About

Dr. Gelo Apostol is a physician, educator, and researcher specializing in Environmental Public Health and Climate-Resilient Health Systems. He concurrently serves as a technical advisor to the Philippine Inter-Agency Committee on Environmental Health (IACEH) where he helps convene governments, academia, civil society, and the private sector towards generating evidence, developing policies, and operationalizing programs for the protection of public and planeetary health. Over the past decade, Dr. Apostol has led and served as a consultant to various national, regional, and international environmental health initiatives—from developing the Philippines’ National Environmental Health Action Plan (NEHAP 2030), establishing the Philippine One Health Action Plan, building evidence on the impact of climate change on infectious diseases, mainstreaming air pollution control strategies, and raising public awareness on the health impacts of environmental toxicants. Currently, he leads the country's efforts at combatting Antimicrobial Resistance (AMR) through a One Health Approach. Dr. Apostol received his double degree in Doctor of Medicine and Master of Business Administration (MBA) from the Ateneo School of Medicine and Public Health and Ateneo Graduate School of Business (Class Valedictorian, Batch 2016). He is a Senior Atlantic Fellow for Health Equity at George Washington University, an Environment and Sustainable Development fellow of the US Department of State, and a scholar and Post-Graduate fellow at Murdoch University - Australia, specializing in One Health. He completed his MSc in Global Public Health from Queen Mary University of London, and completing his PhD at James Cook University Australia.

    POLICY BRIEF: From Research to Impact: Transformative Actions Against Arsenic Groundwater Contamination In Batangas

    On the 12th of January 2020, Taal Volcano, located in Southwest Luzon in the Philippines, erupted greatly impacting the livelihood and health of the people in Batangas Province. With majority of Batangas province relying on the groundwater aquifer surrounding Taal Volcano, one of the world’s most active volcanoes globally, for drinking water, this volcanic event followed by continuous volcanic activity throughout 2020 prompted an investigation on the quality of groundwater sources in communities surrounding the volcano.

    A TAALe of Arsenic: Sharing the narrative through an interactive map

    Arsenic is a highly toxic and carcinogenic trace metal that can potentially contaminate groundwater sources in volcanic regions and affect communities in the area, like those residing around the Taal Volcano. The volcano’s eruption last 2020 encouraged an investigation into the quality of groundwater sources in communities surrounding the volcano. In response, the EnviHealth team in ACRI conducted a comparative documentation, “Arsenic in Groundwater Sources from Selected Communities Surrounding Taal Volcano, Philippines”. Water samples from 26 wells were collected across 11 municipalities and 1 city in Batangas province within danger zones from the volcano which were used to analyze total arsenic levels of the samples. Geographic coordinates of the sampling points were also recorded for mapping.

    Policy Brief: Mitigating Dengue in a Warming World

    Strategies Against Dengue Outbreaks The study is the first nationwide analysis of the impact of climate-induced temperature changes on dengue incidence in the Philippines. It provides a nuanced understanding of the intertwined relationship between dengue and rising temperatures worsened by climate change and the socio-economic factors that affect it.

    Policy Brief: Strengthening Regulation of PFAS in Food Packaging Perspectives from the Philippines

    Per- and Polyfluoroalkyl- substances (PFAS), a group of chemicals widely linked to a variety of health conditions, including cancer, immunotoxicity, cardiorespiratory diseases, endocrine toxicity, reproductive issues, and neurodevelopmental complications, has been found to be commonly used in food paper packaging products. Women, children, and factory workers are at higher risk to these negative health impacts due to inherent age and sex-related vulnerabilities and increased exposure. This scoping review investigates the existing policies and regulations for PFAS use in food paper packaging in the Philippines, as well as the gaps and challenges in mitigating risk exposure in vulnerable populations.
