A study on distribution of heavy metal pollution on the urban parks soils in Çankırı, Türkiye

Abstract

Soil is a crucial component of rural and urban environments. Urban soils in Çankırı have a high potential impact on soil quality. To date, little research on soil pollution has been conducted in Çankırı's urban parks has been conducted. To identify the concentrations and sources of heavy metals in soil, and to assess the soil environmental quality, samples were collected from 10 urban parks soils and different time located in the city of Çankırı (total 90 soil samples). The concentrations of B, Cd, Cr, Fe, Mn, Cu, Ni, Pb, and Zn were analyzed in the samples using an ICP (Inductively Coupled Plasma Mass Spectrometry). The mean concentrations (mg/l) were Mn>Fe>Zn>Cu>Ni>Pb>B>Cd>Cr. Considering the heavy metal concentrations obtained in the study, all of these values were found below the acceptable However, in some parks of the study area, some elements were also slightly raised, the transported soils in urban parks should be handled carefully and to avoid an environmental hazard of these heavy metals.

Çankırı’daki kent parkları topraklarında ağır metal kirliliğinin dağılımı

Öz

Toprak, kırsal ve kentsel çevrenin önemli bir bileşenidir. Çankırı'daki kentsel topraklar, toprak kalitesi üzerinde yüksek bir potansiyel etkiye sahiptir. Bugüne kadar, Çankırı'nın kentsel parklarında toprak kirliliği üzerine çok az araştırma yapılmıştır. Topraktaki ağır metallerin konsantrasyonlarını ve kaynaklarını belirlemek ve toprağın çevresel kalitesini değerlendirmek için, Çankırı kentinde bulunan 10 kent parkı toprağından ve farklı zamanlarda örnekler toplanmıştır (toplam 90 toprak örneği). Örneklerdeki B, Cd, Cr, Fe, Mn, Cu, Ni, Pb ve Zn konsantrasyonları analiz edilmiştir. Ağır metal konsantrasyonları ICP (İndüktif Eşleşmiş Plazma Kütle Spektrometresi) kullanılarak analiz edilmiştir. Ortalama konsantrasyonlar (mg/l) Mn>Fe>Zn>Cu>Ni>Pb>B>Cd>Cr şeklindeydi. Çalışmada elde edilen ağır metal konsantrasyonları göz önüne alındığında, bu değerlerin tümü kabul edilebilir değerlerin altında bulunmuştur. Ancak, çalışma alanındaki bazı parklarda bazı elementler de hafifçe yükselmiştir, kent parklarındaki taşınan topraklar dikkatli bir şekilde ele alınmalı ve bu ağır metallerin çevresel bir tehlikesinden kaçınılmalıdır.
