Metals in seawater, sediment and Padina australis (Hauck, 1887) algae in the waters of North Sulawesi

Metals in North Sulawesi waters can originate from mining and other anthropogenic activities or natural causes. The objective of the study was to examine the presence of arsenic (As), copper (Cu), zinc (Zn) and mercury (Hg) in the water, sediment and thallus of brown alga Padina australis in several...

More Information
Summary:Metals in North Sulawesi waters can originate from mining and other anthropogenic activities or natural causes. The objective of the study was to examine the presence of arsenic (As), copper (Cu), zinc (Zn) and mercury (Hg) in the water, sediment and thallus of brown alga Padina australis in several waters of North Sulawesi, like Totok Bay, Manado Bay, Talawaan Bajo and Likupang waters. Sample analyses were conducted for seawater, sediment and marine algae from the sea sampling point, in two dates during dry season and rainy season. The analyses followed American Public Health Association (APHA) and United States Environmental Protection Agency (USEPA) recommendations using ICP-OES (Inductively Coupled Plasma)-(Optical Emission Spectrometry). Metal concentration in the seawater from all sampling points was the same for both dates. The metal concentration in the sediment from the four sampling points ranges from 1 to 3 ppm for As, 9 to 26 ppm for Cu, 17 to 131 ppm for Zn, and 0.05 to 3.2 ppm for Hg. The metal concentration in the P. australis thallus in the four sampling points is between 1.1-19.5 ppm for As, 0.5-4.4 ppm for Cu, 1.2-19.9 ppm for Zn and 0.003-0.758 ppm for Hg.
