Abstract

This research aims at evaluating water-quality characteristics in Limboto Lake ecosystem in accordance with its designation. The research took place in Limboto Lake and the rivers that drain water into the lake. Samples were taken at 5 spots in Limboto Lake and 8 spots at the surrounding rivers. The rivers that flow into Limboto Lake and were made as samples consisted of Alo River (3 samples), Toyidito River (2 samples), Molamahu River (1 sample), Molalahu River (1 sample) and also Alopohu Dam (1 sample). Instruments used were pH meter and thermometer for physical parameters, and AAS for chemical parameters. Microbiology was measured using MPN method. The results of the analysis indicated that the water quality in Limboto Lake and the surrounding rivers were polluted. The parameters of nitrate, phosphate and hydrogen sulfide were above the standard stipulated by the Government Regulation Number 82 of 2001.

Abstract

This study aims to identify mercury concentrations in head hair and its effect on public health at the traditional gold mining. The study was conducted at the gold mining, Buladu Village, North Gorontalo Regency. Samples were taken randomly from human head hair. Samples of public health condition were taken from respondents who served as the samples of mercury concentrations in the head hair. The number of respondents was 20 people. The samples of mercury in the head hair were analyzed at the Integrated Research and Testing Laboratory of UGM by using mercury analyzer. The quality standard used as a reference to the mercury concentrations   in the head hair was the recommendation of the National Research Council (NCR), i.e. 12 ppm. The results of the analysis of the public health were tabulated and then interpreted. The results of the analysis indicated that the highest mercury concentration in the head hair was 952.85 mg/kg and the lowest was 0.03 mg/kg with an average mercury concentration of 55.09 mg/kg. This result was above the threshold quality standards established by NCR, i.e. 12 ppm. Many factors affect the mercury concentrations in humans, including education, income, environmental sanitation and food consumption. Waste dumped directly into the river will affect river water and marine aquatic animals. The consumption of food taken from the waters of Sulawesi Sea affects influence the mercury concentrations in the head hair.
