“…In this study, the alleged contents of organic and inorganic materials in leachate, especially for heavy metals and ammonium, are considered as the cause of the hyperplasia of epithelial cell. The same histological changes have also been reported in some studies of C. carpio describing ammonium (Devaraj et al, 2014;Chezhian et al, 2012) and the exposure of lead (Pb) (Natalia, 2007). Chemical pollutants and heavy metals that mostly cause hyperplasia are Cadmium (Cd), Cuprum (Cu) and Zinc (Zn) (Saputra et al, 2013).…”

“…Chezhian et al (2012) and Devaraj et al (2014) reported the closer move of gill epithelium (via cell hypertrophy) is sometimes considered as one indicator of cell degeneration and eventually signs of early necrosis. The pooling caused the gill surface area reduce the respiration process, so that the respired oxygen decreased.…”

“…Lesions may interrupt the oxygen uptake through the gills (20), in severe conditions resulting in high mortality of fish at low and elevated pH (35,36). According to Wilkie et al (37), one major problem often encountered by fish in alkaline environments is a severe depression of plasma electrolyte levels.…”

“…Часто процес нітрифікації залишається незавершеним, що тимчасово створює надмірний фон нітриту, який в 10 разів токсичніший за нітрати (Zubina, 1967;Cherkesova and Shahnazarova, 2002;Hutyi, 2004;Nazaruk et al, 2015). Це призводить до зниження вмісту кисню у воді (Zubina, 1967;Zorriehzahra et al, 2010), утворення в тілі риби нітрозамінів, які мають високу токсичність, тератогенність і канцерогенність (Veldre and Rooma, 1990;Mazik et al, 1991;Svobodova et al, 2005;, а також у крові утворюється метгемоглобін (William et al, 1986;Staryk et al, 2012;Lapirova, 2016;Nazaruk et al, 2016;Huberuk et al, 2017), який візуально проявляється зміною кольору крові з червоного на коричневий (Kushakovskij, 1970;Doblander and Lackner, 1997;Tilak et al, 2002;Chezhian et al, 2012;. Небезпечним є той факт, що рибоводи не помічають симптомів нітритного отруєння до тих пір, поки не починається загибель риб.…”
