Seasonal Variation of Some Trace Element and Heavy Metal Concentrations in a Turkish Stream

Abstract

Water is a key element for the existence of living organisms and these organisms provide the surface water and groundwater resources to sustain their vital activities [1]. But since two hundred years ago, our natural resources have been polluted as a result of rapid population growth, industrial development and unconscious agricultural activities [1-2]. For this reason, the use of irrigational or industrial purposes of the water is restricted [1]. Waters including high toxic quantities of ingredients used for household activities, irrigation or industrial purposes without any treatment bring some health and environmental problems [3-7]. Therefore, it is important to take precautions due to the foreign material type and their high concentrations in the water [8-9]. It was thought that nature could cope with these

Spatial Investigation of Nilüfer Stream Arsenic Pollution in Previous and Post COVID-19 Pandemic and Evaluation of Health Risks for Adult People

“…High levels of arsenic had also been detected in Bursa and its environs, as well as in Balıkesir and Uşak [5,6] . The Nilüfer Stream, which passes through Bursa, where the textile, automotive, metal and chemical industries were intense, agricultural production and mining was carried out, and which was the 4th largest city of Turkey, is under intense pressure in terms of metal pollution [7][8][9] . There was Emet and Orhaneli Stream within the borders of Bursa City.…”

Assessment of Heavy Metal Amounts of Spinach Plants (<i>Spinach Oleracea</i> L.) Grown on Cd and Chicken Manure Applied Soil Conditions

“…In parallel with the increase in the human population and the development of today's technology, the natural distribution pattern and concentrations of heavy metals are significantly increased due to the industrial activities such as energy and fuel production, radioactive wastes, mining, sludge applications. Nowadays, anthropogenic activities such as excessive usage of fertilizers and pesticides, and irrigation with wastewater were added in to the list [6]. It is reported that the metal concentration in the soil varies between 1 and 100,000 mg kg −1 , and high heavy metal levels cause degradation in ecological balance by causing a decrease in soil, product, yield and quality [7][8][9].…”
