Ammonia toxicity in the Siberian sturgeon was analysed, and the 24 h LC50 was performed for different weight groups. This sensitivity is currently determined by normalized tests of short duration, even if their practical application is difficult. During exposure to high levels of ammonia, we also ...
In this present study, fixed鈥恇ed biofiltration technique was implemented to remove the ammonia at high concentration of 20 mgN/L. The results indicated that the effluent reached the standard of domestic and drinking water quality (the ammonia concentration < 3 mgN/L) at all investigated ammonia...
Naturally occurring arsenic, typically harmless in its natural state, can undergo transformation into inorganic arsenic, thereby contaminating groundwater sources used for drinking or irrigating crops. The accumulation of arsenic from one trophic level to another level, depends not only on the total ars...

The ammonia levels in wastewater can range up to and over 5000 ppm. In aquarium and aquaculture systems it is not unusual to encounter total ammonia concentrations of between 1.0 and 3.0 ppm. Another fish threatening substance is chlorine. Chlorine is most often present in water as a result ...
This transporter is also somewhat unique in that it is relatively rapidly recycled between the plasma membrane and the cell surface (Fournier et al., 2004; Gonzalez et al., 2007). In vivo, it seems that most EAAC1 protein is found on intracellular vesicles, and the levels of EAAC1...

leading to disruptions in delicate ecological balances8. Ammonia can also find its way into domestic water supplies as a natural degradation byproduct of nitrogenous organic matter9. Groundwater can have high ammonia levels in certain regions due to geological permeability10. Short and long-term expo...
