Heavy metal accumulation in irrigated soil with wastewater

Ağır metaller önemli bir kirletici grup olarak bilinir. Toksik ve kanserojen etkisi yanında canlılarda birikme eğilimi gösterirler. Konya atıksu ana tahliye kanalı civarındaki çiftçilerin kanala deşarj edilen atıksuları tarımda sulama amaçlı kullanmaları ile verimli topraklar kirlenmekte ve bitki kalitesi olumsuz yönde etkilenmektedir Bu araştırma, Konya Ana Tahliye Kanalı boyunca kanalizasyon suları ile sulanan topraktaki ağır metal birikmesinin tespiti amacı ile yapılmıştır. Çalışma sonucunda, sulamanın yapıldığı tarımsal arazide ağır metallerden Zn, Cu, Mn, Cr, Ni, Pb and Cd konsantrasyonlarında önemli artışlar tespit edilmiştir.

It is known that heavy metals form an important polluting group. They have not only toxic and carcinogen effect but also tend to accumulate in living organisms. Using the water discharged into the channel by the farmers in Konya for irrigation, causes to pollution of the fertile soils and affects the plant quality negatively. This study was carried out to determine the heavy metal deposit in the fields irrigated with sewage along the main discharge channel of Konya. As the result of the study, it was determined that using the sewage for irrigation significantly increased heavy metals such as Zn, Cu, Mn, Cr, Ni, Pb, and Cd concentrations of the soils.
