The impact of the Mondi Syktyvkar Timber Industry Complex on the chemical composition of pine needles was investigated. A comparative analysis of the mineral composition of pine needles showed that the age dynamics of the content of the vast majority of investigated elements in the case of both the studied background region and the zone affected by anthropogenic emissions demonstrated similar trends. The total content of chemical elements in bilberry pine forests showed no difference depending on the needle age or the distance from the source of pollution. An examination carried out in 2007 revealed that the total element concentration in one year old pine needles was higher than that in older ones. Over the period of studies, a decrease in pine needle mineralization was observed under the influence of pollution in comparison with the background territory. Additionally, aerotechnogenic emissions of nitrogen and sulfur oxides as well as carbon containing compounds resulted in no accumulation of the above mentioned substances in pine needles except for the impacted stand of 1.3 km.
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.
