Abstract:

 Sanitary landfill leachate poses a significant threat to soil health. Heavy metals found in leachate have negative effects on both humans and the land ecosystem. The pollution concentration of leachate may vary depending on factors such as environmental and stored waste content. Within the scope of this study, samples were taken weekly from the Niğde province solid waste landfill leachate for a year November 2022-October 2023, and the formation and seasonal change of Fe, Pb, Zn heavy metals were examined with trend analysis and evaluated in terms of environmental health. Non-parametric Mann-Kendall test MKT and Spearmans Rho test SRT were used to perform trend analysis. The computer software Trend Analysis for Windows was selected for conducting trend analysis of pollutants was used in Delphi 7.0 programming language. MK and SR Test and Sens Trend Slope method were applied to pollutant parameters at 95 confidence level. By performing polynomial linear regression analysis of the pollutants, R2 was calculated as 0.93, 0.89 and 0.33, respectively. These heavy metals in the leachate varied seasonally. As a result of the analysis, it was determined that heavy metal concentrations were at normal values for a landfill area in the young-middle age range. Since the water from the leachate pool in the landfill area is sent to the advanced biological wastewater treatment facility in the province through wastewater sewer, it does not pose a possible environmental health risk.

 Düzenli depolama sahası sızıntı suları toprak sağlığı için önemli tehdit altındadır. Sızıntı suyunda bulunan ağır metaller hem insanlar üzerinde hem de kara ekosistemi üzerinde negatif etkiler yaratmaktadır. Sızıntı sularının kirlilik konsantrasyonu çevresel ve depolanan atık içeriği gibi faktörler ile değişebilmektedir. Bu çalışma kapsamında, Niğde ili katı atık düzenli depolama alanı sızıntı sularından bir yıl boyunca Kasım 2022-Ekim 2023 haftalık olarak numune alınarak, içerisindeki Fe, Pb, Zn ağır metallerin oluşumunu ve mevsimsel değişimini trend analiziyle inceleyerek, çevre sağlığı açısından değerlendirilmesi yapılmıştır. Trend analizini yapmak amacıyla parametrik olmayan Mann-Kendall testi MKT ve Spearmanın Rho testi SRT kullanılmıştır. Kirleticilerin trend analizini yapmak için kullanılacak bilgisayar yazılımı Trend Analysis for Windows, Delphi 7.0 programlama dilinden yararlanılmıştır. Kirletici parametrelere MK ve SR Testi ve Senin Trend Eğim metodu 95 güven seviyesinde uygulanmıştır. Kirleticilerin polinomsal lineer regresyon analizi yapılarak R2 sırasıyla 0.93, 0.89 ve 0.33 hesaplanmıştır. Sızıntı suyundaki bu ağır metaller mevsimsel olarak farklılık göstermişlerdir. Analizler sonucu genç-orta yaş aralığında bulunan bir deponi alanı için ağır metal konsantrasyonları normal değerlerde olduğu tespit edilmiştir. Deponi alanında sızıntı su havuzundan suların atıksu kanalizasyon aracılığıyla ildeki ileri biyolojik atıksu arıtma tesisine gönderilmekte olduğu için olası bir çevre sağlığı riski taşımamaktadır.
