2015 Wang Tropical vs. Temperate organisms susceptibility to ammonia 01 Abstract Suscptability to Ammonia in Temperate versus Tropical Organisms 02 Introduction Towards more Robust data on Tropical Species 03 Data Invertibrates, fish and algae: Susceptibility to Ammonium Chloride solution 04 Results Invertibrates, Fish and Algae were Increasingly Tolerant to Ammonia 06 Discussion Toxicity of NH3 Used in this Study Differed Greatly Among Ttest Species 07 Conclusion Based on the Current Results, Concentrations of 15 mg L-1 NH3 and 1.5 mg L-1 NH3 at pH 7.0 and 25 C are recommended as interim acute and chronic PNECs for tropical areas, respectively. Most published data on ammonia toxicity is on cold water species. In this paper, Wang et al perform tests on tropical species and provide insight into the variability of susceptibility to tropical organisms to ammonia - which varied widely. No surprises here, invertebrates were the most susceptible, then fish, while algae was the least susceptible to ammonia poisoning.
