Seasonal variation of some heavy metal pollution with environmental and microbiological parameters in sub-basin of Kocabas Stream (Biga, Canakkale, Turkey) by ICP-AES

Abstract

Waste water pollution in industrial areas is one of the most important environmental problems. Heavy metal pollution, especially chromium species in waste water sources from tannery affects our lives. Kocabas Stream is located in south-west Marmara region and Biga town is positioned in the sub basin on the stream. This water source functions as the water for irrigation in agriculture, drinking water for animals and for human use. Thus, this study is of great importance. Waste water pollution can affect all ecosystems and human health by directly or indirectly as in food chain. The concentration of heavy metals (Pb, Cd, Cu, Zn and Cr) were pre-analysed by ICP-AES method in water samples taken from sub-basin of Kocabas stream. In the results of these analyses, concentrations of the metals except chromium were founded at the limit value. But the total concentration of the Cr was found at high levels of between 0.0082 +/- 0.0001 and 5.7231 +/- 0.0921 mg l(-1) over the limit value (0.05 mg l(-1); WHO, EPA, TSE 266 and inland water quality classification) at sampling points very close to tannery factories. Also physicochemical and microbiological parameters of Kocabas Stream were determined. The effects of the experimental results on environment were investigated.

Assessment of the characteristic of nutrients, total metals, and fecal coliform in Sibu Laut River, Sarawak, Malaysia

“…Positive loadings on temperature, conductivity, TDS, total Pb, and total Zn; and negative loading of FC were observed in the PCA. This agrees well with the previous studies that increase in temperature (Chigbu et al 2004;Noble et al 2004), salinity (Hamzah et al 2011;Yayintaş et al 2007), and heavy metals (Malik and Ahmad 2002;Jana and Bhattacharya 1988) were harmful to FC survival in natural environments. Besides, the negative loadings on FC, turbidity and TSS are not surprising.…”

Impact of Genotoxic Contaminants on DNA Integrity of Copepod from Freshwater Bodies in Chennai, Tamil Nadu, India

“…The Concentration of all the metals is higher in plankton from both seasons. The result was similar to that reported by Yayintas et al [24]. In the present study, abiotic parameters such as temperature, pH and dissolved oxygen were observed very low at Retteri and Velachery Lake.…”

Study of heavy metal pollution in seawater of Kepez harbor of Canakkale (Turkey)

“…The voltammetric method was firstly used to determine the concentration of Cd and Pb in seawater (Neeb 1959). Recently, anodic stripping voltammetry was also used to this purpose (Zirino et al 1973;Abdullah et al 1976;Gillain et al 1979;Jurado-Gonzelez et al 2003;Van den Berg 1986).…”
