Ciddi çevre sorunları haline gelen ağır metaller (HM'ler), genellikle maden kaynaklarının geliştirilmesi de dahil olmak üzere insan faaliyetlerinden kaynaklanmaktadır. Sepiyolit, hidratlanmış magnezyum silikat içeren bir kil mineralidir ve inşaat, tarım, gıda, gübre, ilaç, deterjan, kozmetik, boya, kağıt vb. alanlarda yaygın olarak kullanılmaktadır. Bu çalışmada, üç ocaktan toplanan sepiolit numunelerindeki bazı HM'lerin konsantrasyonları incelenmiştir. Türkiye'nin İç Anadolu Bölgesi'nde bulunan (Polatlı, Beylikova ve Sivrihisar) enerji dağılımlı X-ışını floresans spektroskopisi kullanılarak belirlenmiş ve ayrıca HM'ler için zenginleştirme faktörü (EF) hesaplanmıştır. Sepiyolit numunelerinde analiz edilen Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Zr, Cd, Sn ve Pb ortalama konsantrasyonları 361, 42, 16, 65, 3832, 9, Sırasıyla 24, 8, 12, 5, 25, 4, 7 ve 5 mg/kg. V, Co, Ni, Pb, As, Cd ve Sn'nin ortalama EF değerleri, sepiolit numunelerinde önemli ila aşırı yüksek zenginleşmeyi göstermektedir.

Determination of Heavy Metal Concentrations In Natural Clay Mineral Samples From Quarries In Turkey

Öz

Environmental pollution of heavy metals is increasingly becoming a problem and has become of great concern due to the adverse effects it is causing around the world. Today, various chemical, biological, and physical pollutants arising as a result of rapidpopulation growth, industrialization, and excessive mining activities have become a major problem that adversely affects people, animals, plants, organisms, and ecosystems all over the world. Sepiolite is a clay mineral containing hydrated magnesium silicate and widely used in construction, agriculture, food, fertilizer, pharmaceutical, detergent, cosmetics, paint, paper, etc. The average concentrations of Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Sr, Zr, Cd, Sn, Ba and Pb analyzed in sepiolite samples collected from three quarries (Polatlı, Beylikova, and Sivrihisar) located in the Central Anatolian Region of Turkey using EDXRF spectroscopy were found as 5456.5, 361.0, 42.0, 15.5, 65.2, 3831.5, 8.6, 23.7, 7.8, 11.8, 5.3, 13.7, 1183.2, 25.3, 3.7, 7.2, 131.9 and 5.3 mg/kg, respectively. The average enrichment factor values of V, Cr, Co, Ni, Cu, Zn, As, Sr, Cd, Sn, Ba, and Pb indicated minimal to extremely high enrichment in sepiolite. The values of non-carcinogenic risk index and cancer risk estimated to evaluate potentially health risks caused by PTEs in sepiolite samples were within the acceptable limit and the safe range except for the Beylikova quarry.
