Abstract It is important to investigate the monthly level of trace metals in freshwater systems to assess environmental health. This information can be used to support effective management and control of natural areas in regard to the introduction and bioavailability of chemicals in the aquatic environment. We aimed to determine monthly changes in the levels of aluminum (Al), arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), lead (Pb), mercury (Hg), zinc (Zn), nickel (Ni), and selenium (Se) in water, sediment, and fish samples from Lake Mogan. Five different stations were established in Lake Mogan. Water and sediment samples as well as muscle, liver, kidney, gill, and brain tissues from fish were obtained from these stations every month for 1 year. All analyses were conducted with ICP-OES. In descending order of intensity, the metals identified in the water samples were Fe, Cu, Cr, Zn, Pb, Ni, As, Se, and Hg; those identified in the sediment samples were Fe, Zn, Cu, Ni, Se, Pb, Cr, As, Al, Cd, and Hg; and those identified in fish tissues were Se, Fe, Zn, Cr, Al, Pb, Cu, Ni, As, Hg, and Cd. The most polluted station was located where waste from restaurants and tea gardens were dumped. The level of waste, and thus the level of pollution, was especially high in August. It is concluded that the metals that accumulate in water, sediment, and fish in Lake Mogan originate from anthropogenic activities. Keywords Fish . Metal . Monthly change . Sediment . Water . ICP-OES
Introduction Environmental pollution affects all living organism, and it is one of the most important and widespread problems in many industrialized and developed countries. Water is very important for all kinds of life, from microorganisms to humans, and thus it is crucial to avoid water pollution [1]. However, water has very strong solvent properties that make pollution easy. Today, due to unplanned urbanization and industrialization, pollution in almost all water resources has reached a degree of crisis [2]. Metals have the greatest effect of any pollutant on *This study was summarized from same named PhD thesis by Asli Gul Kucukosmanoglu, Graduate School of Health Sciences, Ankara University.

the aquatic ecosystem due to their toxicity and persistence in the environment, which lead them to accumulate in aquatic organisms [3]. Certain metals such as lead (Pb), cadmium (Cd), and mercury (Hg) can cause damage to planktons, aquatic plants, invertebrates, and ve
