“…Thus, increase in the acidity of the surface waters-which is caused by the possible dissolution of sulphide minerals from the mine sites (Ezeh and Anike 2009;Zhang et al 2012), will subsequently result to increase in their ability to dissolve solutes. Similar pH, EC, and TDS values have been reported by Okolo et al (2018) and Kacmaz (2020) in surface water samples from the same study area and in a mining district in Turkey, respectively. The average concentration level (mg/L) of PTEs in surface waters within the mine catchment area is 0.10, 8.09, 1.54, and 3.77, for Pb, Zn, Cd, and As, respectively (Table 6).…”

Artisanal mining activities in Enyigba community and its environs have become a major environmental problem, which exposes the water, soil, and vegetation within the environment to potential toxic elements (PTEs). However, the lateral extent that the PTEs have spread within the environment has not been ascertained. It is important to determine the lateral extent of the PTEs within the environment to establish safe zones for drinking water usage and for crop cultivation. For this reason, about nine samples each for soil, sediment, vegetation, surface and groundwater were collected within and beyond the mine sites catchment area. The physicochemical properties of these samples were determined following standard procedures, whereas the concentration of PTEs such as cadmium, arsenic, zinc, and lead in them were determined using atomic absorption spectroscopy method. Statistical analysis, biogeochemical analysis, and geospatial information system (GIS) analytical tools were employed to interpret the field and laboratory results. The results revealed that proximity to mine site contributed significantly to the concentration level of PTEs within the environment. The concentration level of the PTEs was higher in water, soil, sediment, and vegetation samples that were collected close to the mine sites, which gradually reduces farther away from the potential pollutant source points. The environmental mobility index and soil-plant bioconcentration factor revealed that cadmium, arsenic, and zinc are more mobile and bioavailable than lead, thus their toxicity within the study area environment are more likely than that of lead.

“…Mineralized areas in particular have high metal concentrations due to their natural properties. In his study conducted in Turkey, Kacmaz 6 stated that many streams, springs and deeper ground waters in mineralized regions contained high metal concentrations. In recent years, as a result of the development of important sectors such as agriculture, battery production, metal plating the discharge of heavy metals into the environment has increased both directly and indirectly.…”

Recently, the search for low-cost eco-friendly adsorbents has become one of the main objectives of researchers. The aim of this study was to test the removal of four heavy metals, namely lead (Pb), zinc (Zn), nickel (Ni) and cadmium (Cd), from a simulated watery solution using brewed tea waste as a potentially suitable adsorbent. The effects of pH levels (2.0–6.0), adsorbent amount (0.1–5.0 g), contact times (1–150 min.) were examined throughout the adsorption process. The results of the experiments showed that the heavy metals elimination yields had an inverse relationship with pH and a linear relationship between the other parameters. The optimum pH for the removal of the heavy metals was between 4.0 and 5.0 in the case of the brewed tea waste. Equilibrium times of 2, 10, 30 and 5 min were required for the adsorption of Pb, Zn, Ni, Cd onto Camellia sinensis, respectively. Based on the results of this study it can be said that brewed tea waste has a high potential to remove heavy metals from aqueous solutions. The maximum adsorption capacities were calculated as 1.197, 1.457, 1.163 and 2.468 mg/g, for Pb, Zn, Ni and Cd, respectively, by fitting the equilibrium data to the Langmuir isotherm model.

“…Hg, Pb, Zn, As, Cd, Co, Cu, Ni, etc.,) could be toxic to plants if present in excess amount of concentrations in irrigation water (Ayers and Westcot 1985). It was reported earlier by Kacmaz (2020) that the surface waters, in general, have low heavy metal concentrations that did not exceed criteria for drinking water of the United States Environmental , 2018). Based on this, it can be said that the values of existing concentrations in the waters are not a level to pose threat to plants.…”

“…One of which has been made by Kazancı et al (2010), is relevant to the assessment of the ecological quality of Aksu river water. The other one is a study carried out by Kacmaz (2020) to determine the heavy metal contamination in natural waters of the Dereli area. The present study has focused to assess primarily on some physicochemical characteristics might adversely affecting the quality of surface waters.…”
