ESKİŞEHİR ATIK DEPOLAMA SAHASI DRENAJ ALANINDAKİ TOPRAKTA AĞIR METAL KİRLİLİĞİNİN İNCELENMESİ

Öz

Bu çalışmada, Türkiye’nin kuzeybatısında yer alan Eskişehir düzenli depolama sahası drenaj alanındaki topraklarda ağır metal kirliliğinin düzeyi araştırılmıştır. Uzun süreli atık depolama ve sızıntı sularının olası çevresel etkilerini değerlendirmek amacıyla, depolama sahasının mansabında 30 m derinliğe kadar iki adet sondaj kuyusu açılmış ve 2021 yılında yağışlı (Mayıs) ve kurak (Eylül) dönemlerde toprak örnekleri alınmıştır. Toprak örneklerinde Mn, Fe, Co, Ni, Cu, As, Cd, Pb, Zn, Cr ve Hg konsantrasyonları ile pH değerleri belirlenmiştir. Kirlilik düzeylerinin değerlendirilmesinde kontaminasyon faktörü (CF), kirlilik yük indeksi (PLI) ve jeobirikim indeksi (I_geo) kullanılmıştır. Jeokimyasal verileri desteklemek amacıyla elektrik özdirenç tomografisi (ERT), özpotansiyel (SP) ve direnç ölçümlerini içeren jeofizik çalışmalar gerçekleştirilmiştir. Ölçülen ağır metal konsantrasyonları ulusal toprak mevzuatında tanımlanan sınır değerlerin altında kalmasına rağmen, kirlilik indisleri özellikle Co, Ni ve Cr için yerel ölçekte zenginleşmeye işaret etmektedir. Bu elementler yağışlı dönemde yüksek değerler göstermiş, Cr ise kurak dönemde de görece yüksek seviyelerini korumuştur. PLI sonuçları, çalışma alanında genel olarak düşük düzeyde bir kirlilik yüküne işaret etmektedir. Jeofizik veriler, ağır metal kirliliği ile ilişkili belirgin bir yeraltı anomalisi ortaya koymamıştır. Sonuçlar, düzenli depolama sahası drenaj alanındaki ağır metal birikiminin mevsimsel olarak değişken ve mekânsal olarak sınırlı olduğunu göstermektedir. Bu tür alanlarda uzun vadeli çevresel risklerin değerlendirilmesi için jeokimyasal ve jeofizik yöntemlerin birlikte kullanıldığı periyodik izleme çalışmalarının sürdürülmesi önerilmektedir.

INVESTIGATION OF HEAVY METAL POLLUTION IN SOIL IN ESKISEHIR LANDFILL DRAINAGE AREA

Öz

This study assesses the extent of heavy metal contamination in the soil of the Eskişehir landfill drainage area in northwest Türkiye, where long-term waste accumulation and leachate pose potential environmental risks. Two boreholes were drilled to a depth of 30 meters downstream of the landfill site, and soil samples were collected during both wet (May) and dry (September) seasons in 2021. Concentrations of manganese, iron, cobalt, nickel, copper, arsenic, cadmium, lead, zinc, chromium, and mercury were determined together with pH values. Pollution indices, such as the contamination factor, pollution load index, and geoaccumulation index, were used to evaluate contamination levels. To support the geochemical results, geophysical surveys including electrical resistivity tomography, self-potential, and resistance measurements were carried out. Although measured heavy metal concentrations stayed below the legal thresholds set by national soil regulations, the calculated indices indicated localised contamination, particularly for cobalt, nickel, and chromium, which showed high levels during the wet season and remained elevated for chromium during the dry season. The pollution load index suggested a generally low overall pollution risk. Geophysical measurements did not reveal significant subsurface contamination-related anomalies. These findings demonstrate that heavy metal accumulation in the landfill drainage area is both seasonally variable and spatially localised. Periodic monitoring combining geochemical and geophysical approaches is recommended to manage and mitigate long-term risks in such waste storage environments.
