Acute Toxicity of Ammonium sulfate fertilizer to Bufo Bufo tadpoles from Turkey
Bu çalışmada, amonyum sülfatın Bufo bufo larvaları üzerindeki akut toksikolojik etkileri belirlenmiştir. Bu nedenle, hayvanlar (Gosner 32 aşamasında) 96 s. boyunca altı farklı amonyum sülfat konsantrasyonuna (75, 100, 250, 500, 750 ve 1000 mg / L) maruz bırakılmıştır. Test sonunda bazı morfolojik ve davranışsal anormallikler tespit edildi. Yüksek konsantrasyonlarda amonyum muamelesine maruz kalan larvalarda düzensiz yüzme, ödem, omurga eğriliği, depigmentasyon görüldü.Ölü larvalar sadece 750 ve 1000 mg/L'de mevcuttu. Kaplan-Meier sağkalım testine göre uygulamalar arasında anlamlı fark yoktu. Kontrol grubu ile uygulama grupları arasında vücut uzunluğu ve kilo bakımından istatistiksel farklar tespit edildi. Bu çalışmanın sonuçları, sadece yüksek amonyum konsantrasyonlarının larvalar üzerinde öldürücü etkilere sahip olduğunu göstermesine rağmen, amfibiler üzerinde amonyumun riskini değerlendirirken test hayvanlarının gelişim aşamasının dikkate alınması gerektiği unutulmamalıdır.
