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.
