Pimentel Capiz State University – Burias Campus Bur-ias, Mambusao, Capiz 5807 , Philippines sspimentel@capsu.edu.ph This research study is based on the current status of heavy metal contamination in bivalves within the coast- al areas of Capiz, Philippines, drawing insights from accessi- ble data. The findings shed light on the contamination’s ex- tent, potential threats to human health, and the pollution’s origins. The researchers acknowledge the study’s limitations. As per the findings, elevated levels of heavy metals, such as lead, mercury, cadmium, arsenic, and chromium, in bivalves collected from Capiz’s coastal regions. Variations in metal concentrations are observed among different bivalve species and sampling sites, with identified geographical distribution patterns and potential contam- ination hotspots. An assessment of conformity to regulatory lim- its and guidance for heavy metal levels in shellfish consumption is conducted, identifying any exceedances or areas of concern. The research aims to establish the extent to which bivalves from Capiz align with legal requirements. Potential health risks allied to the bivalve consumption are evaluated based on the detected heavy metal levels, considering various exposure routes, popula- tion characteristics, and toxicity reference values. The research scrutinizes the impact of human activities, including industrial dis- charges, agricultural practices, and urban runoff, on heavy met- al contamination in coastal ecosystems. The ongoing discussion underscores the need for further investigation and underscores the importance of addressing the issue to ensure the environ- mental sustainability and safety of coastal resources in Capiz. INTRODUCTION 1.1 Historical Context of the Investigation Heavy metals are a kind of naturally occurring el- ement that may be discovered in the crust of the Earth. They are distinguished by their high densi- ty and poisonous qualities, which, when present in excessive levels, pose a harm to human health as well as the environment. The release of heavy metals into the environment may occur as a result of a variety of human-caused activities, including industrial operations, mining techniques, and ag- ricultural practices. After being discharged into the environment, they have the potential to build up in chemical element chromium (Cr)aquatic ecosystems, especially coastal regions, and then Philippines Heavy Metals In Bivalves From Coastal Municipalities Of Capiz, DOI: 10.59762/seer924712041120240705093505
