ABSTRACT: Using Flame Atomic Absorption Spectrophotometer, concentrations of chromium, copper, lead and manganese were examined from the sediments in the coastal area of Tagoloan, Misamis Oriental for two months. There were four sampling points in which Point D, a non-industrial zone of Tagoloan, was found to contain all the highest heavy metal concentrations. Point A has the lowest chromium, lead and manganese concentrations while the copper concentration is lowest at Point C. Average concentration of chromium, copper, lead and manganese in the sediments were 205.5, 61.70, 19.93 and 520.0 ppm, respectively. No significant differences were found on copper and lead concentrations with respect to the four sampling points whereas chromium and manganese have significant variations. Statistically, chromium exceeded the severe effect level set by US-EPA. Copper have concentration that exceeds the lowest effect level but not on its severe effect level. Both lead and manganese falls below the two criteria.
