Abstract
This study was conducted to determine presence of heavy metals (Cd, Cr, As, Pb, Hg) in Chanos chanos (Bangus) obtained from selected fish ponds in Northern Samar, Philippines. Environmental parameters of fish pond waters were also determined. Fish pond in Bobon has pH of 8.5, salinity of 390 ppt, turbidity of 1,26m, and temperature of 33, 2°C. San Jose has pH of 8.5, salinity of 380 ppt, turbidity of 2.40m, and 35.1°C and Lavezares has pH of 8.5, salinity of 360 ppt, turbidity of 1,54m, and 33,1°C The heavy metals in samples were analyzed using qualitative and quantitative procedures. Qualitative tests showed that only lead (Pb) metal contamination was detected from bangus meat extract from Bobon and San Jose. Quantitative analysis using Atomic Absorption Spectrophotometer (AAS) revealed very low lead concentration of 0.00003 mg/L in Bobon, 0.00003 mg/L in San Jose and 0.00002 mg/L in Lavezares. The said lead concentration is below the permissible level set by the International Standard Maximum Permissible Level (MPL). The researcher recommends that every municipality must perform educational campaigns on local residents on proper waste disposal to avoid further contamination of marine products.
