This study aims to determine concentration of zinc (Zn) and lead (Pb) metals on the sea water incoastal areas Mamboro District of North Palu. The method used was a spectrophotometry using atomicabsorption spectrophotometer (AAS). Seawater samples were taken from three different points, is A (5 meter), B (10 meter), and C (15 meter) within ± 5 m from the coastline, and sampling started fromthe edge of the harbor of cooking oil companies. Results of the analysis of zinc contents from the threepoints are 0.155 mg/L at point A, 0.126 mg/L at point B, and 0.109 mg/L at point C, respectively.Moreover, the lead contents are 0.35 mg/L at point A, 0.391 mg/L at point B, and 0.433 mg/L at pointC , respectively. Concentration of zinc metal on the sea water in Mamboro coastal marine ranged from0.109 mg/L – 0.155 mg/L, which is higher than the threshold value zinc metal, 0.01 mg/L, whereconcentration of lead metal on the sea water in Mamboro coastal marine ranged from 0.35 mg/L –0.433 mg/L, which is higher than the threshold value of lead metal, 0.025 mg/L.
