Abstract:The results of studies of changes in the activity of catalase in ordinary chernozem, brown forest soil and sierosands under pollution with different of the bismuth chemical compounds: bismuth oxide, carbonate and nitrate are presented. It has been established that bismuth contamination of different types of soils reduces catalase activity, regardless of the chemical compounds. The toxicity of bismuth increases with an increase in the dose applied to the soil. Based on the chemical bismuth compounds, the averag… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
