Environmental risk assessment of sediment and water in Cansaga Bay, Philippines
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 11, Issue 4
Abstract
Physicochemical analysis of Cansaga Bay, Cebu, Philippines was conducted to evaluate bay water and sediment for environmental risks brought by proposed reclamation and development. The main objective was to provide baseline data about the bay prior to development. Analyzed parameters for bay water were dissolved oxygen (DO), pH, % salinity, temperature, total phosphate (PO43–P), ammonia-nitrogen (NH3-N), and total heavy metals (chromium (Cr), lead (Pb), and cadmium (Cd)) and for bay sediments were Pb, Cd, and Cr in total form. Overall, the temperature, pH, DO, and % salinity of bay water were within the permissible limit. However, nutrient loading was pronounced as evidenced by high PO43–P and NH3-N with RQ values > 1. Particularly, Pb and Cd in bay water exceeded the threshold indicating higher environmental risk (RQ >1). The Cd in sediment reached the midrange effect for sediment quality guideline, indicating strong contamination (CF > 6). Despite the high levels of Cd in sediment the bay was less likely polluted as evidenced by PLI values <1.
