Abstract

Bu çalışmada Konya’da bulunan yatak kapasiteleri 27-600 kişi arasında değişen 10 hastanenin atıksuyundan yaz ve kış dönemlerinde örnekler alınarak fizikokimyasal özellikleri belirlenmiş ve Vibrio fischeri, Daphnia magna, Lepidium sativum toksisite testleri ile ekotoksikolojik etkisi belirlenmiştir. Hastane atıksularının pH, elektriksel iletkenlik, askıda katı madde ve toplam organik karbon parametreleri sırasıyla yaz dönemi için 7.16-8.61, 525-7970 µS/cm, 18-1124 mg/L, 53-502 mg/L aralığında, kış döneminde ise 7.10-8.63, 554-4130 µS/cm, 92-860 mg/L, 20-305 mg/L, 143-819 mg/L aralığında tespit edilmiştir. Hastane atıksularının EC50 değerleri yaz döneminde Vibrio fischeri için 0.39-77.72, Daphnia magna için 14.84-85.15, Lepidium sativum için 16.62-87.68 aralığında, kış döneminde Vibrio fischeri için 0.78-100, Daphnia magna için 9.8-49.95, Lepidium sativum için 36.68-42.61 aralığında tespit edilmiştir. EC50 değerlerinden hesaplanan toksik birim değerleri incelendiğinde, araştırılan hastanelerin üçünün atıksuyunda yüksek akut toksisite etkisi gözlenmiştir. Covid-19 pandemisi sebebiyle hastanelerin tam kapasite çalışması ve hastanelerde yoğun farmasötik kullanımına bağlı olarak deşarj edilen kirlilik yükünün artması hastane atıksularının yönetimi açısından bugün daha önemli bir sorun haline gelmiştir. Hastane atıksularının deşarj kriterlerinin belirlenmesinde toksisite testlerinden faydalanılmalıdır.

Evaluation of ecotoxicological effect of hospital wastewater

Abstract

The wastewater of 10 hospitals in Konya with bed capacities ranging from 27-600 person in summer and winter periods. The pH, electrical conductivity, suspended solids and total organic carbon properties of hospital wastewaters are 7.16-8.61, 525-7970 µS/cm, 18-1124 mg/L, 53-502 mg/L in the summer period, and 7.10- 8.63, 554-4130 µS/cm, 92-860 mg/L, 20-305 mg/L, 143-819 mg/L in the winter period. The EC50 values of hospital wastewater are 0.39-77.72 for Vibrio fischeri, 14.84-85.15 for Daphnia magna, 16.62-87.68 for Lepidium sativum in summer, 0.78-100 for Vibrio fischeri, 9.8-49.95 for Daphnia magna, 36.68-42 for Lepidium sativum in winter. When the toxic unit values calculated from the EC50 values were examined, high acute toxicity was observed in the wastewater of three of the hospitals studied. The increase in the discharged pollution load due to the full capacity operation of the hospitals and the insentive use of pharmaceuticals in hospitals due to the Covid-19 pandemic has become a more important problem in terms of the management of hospital wastewater. Toxicity tests should be used to determine the discharge criteria of wastewater such as hospital wastewater.
