“…The amount of oxygen required by organisms in the aerobic metabolic process is represented by BOD, and the amount of chemical oxygen required for the decomposition of organic matter by chemical reaction is represented by COD. COD is also used to estimate the amount of organic matter in water [19]. In aquatic environments such as coastal areas and ports close to cities, low dissolved oxygen levels are observed due to the biological oxygen demand resulting from seasonal temperature changes [20].…”

“…In aquatic environments such as coastal areas and ports close to cities, low dissolved oxygen levels are observed due to the biological oxygen demand resulting from seasonal temperature changes [20]. The low dissolved oxygen level leads to the conversion of the aerobic environment to the anaerobic environment [19], which is a suitable environment for the formation of H2S. Temperature is an important parameter in the H2S formation process due to its significant effect on DO and bacterial activity.…”

“…respectively. In addition H2S concentration was determined as 0.2 ppm [19]. In the study conducted by Ogbemudia and Ita [6] in Lower Stubbs Creek, Qua Iboe River Estuary, Nigeria air quality was assessed with samples taken from 5 different points using portable hand held gas monitors for atmospheric gases.…”

Odor pollution is an important type of pollution that is subject to complaints in terms of quality of life and health. Since the odor perception is a sensorial process that occurs naturally with breathing, it is difficult to avoid when exposed. H2S is one of the main sources of odor pollution and wastewater reservoir, estuarine and polluted river or waterways are among the most suitable areas for H2S formation. The aim of this study is to determine the changes in H2S concentrations on Araç Stream. Therefore, in this study, H2S concentrations were determined instantaneously by using portable handheld gas monitors in air samples from the surface of Araç Stream at 15 points within the boundaries of Karabük city, and at the same time, pH and temperature values were determined. According to results, there were statistically significant differences in the H2S and pH values between the sampling points (p <0.05). H2S concentration decreased in the order according to the sampling points as SP10< SP1< SP11< SP2< SP12< SP3< SP13< SP14< SP7< SP8< SP9< SP15< SP4< SP5< SP6. The highest level was determined after the industrial zone and the lowest levels were determined at the furthest point from the city center and industrial facilities. The results were shown in a map by using ArcMap program of ArcGIS software package.

“…Good water quality includes physical, chemical, and biological quality tests so that when consumed it does not cause side effects for health (Rosyidah, 2017). Isworo et al, (2017) stated that the water quality measurement are included physical, chemical and microbiological parameters that should meet standard of health and environment requirements. According to the Regulation of the Minister of Health No.…”

A study has been carried out on the analysis of the physical and chemical quality of PDAM water in the Teluk Ambon Baguala sub-district. The purpose of this study was to analyze the physical and chemical quality of water from the Regional Drinking Water Company (PDAM) in Halong, Lateri, and Passo villages, including smell, taste, color, temperature, a total of dissolved solids (TDS), pH and hardness. The method used is the observation in the field at the time of sampling, then measurement and analysis in the laboratory. The results of the study indicate that the physical and chemical quality of PDAM water in the Teluk Ambon Baguala sub-district, which are smell, taste, color, total of dissolved solids (TDS), pH and hardness have met the drinking water quality standards according to the Regulation of the Minister of Health No. 492/Menkes/per/IV/2010.
