The paper presents the results of a study of the state of the environment in the area of the Kola Mining and Metallurgical Plant using a bio-indicator of the Siberian spruce needles (Picea obovata). The following deviations in the morphometric parameters of Picea obovata needles were found: a decrease in the length and width, a reduction in the total surface, different types of damage and wilting. In areas with a more intense impact, a regular increase in the average percentage of damaged plants is observed compared to baseline samples. The state of the environment for the suppression of the Siberian spruce needles was assessed as “satisfactory” and “good”.
The problem of the utilization of solid municipal waste is one of the most acute in the Murmansk region. The paper presents a business plan for creating a small enterprise for the processing of recycled paper raw materials in the Murmansk region based on an analysis of information about modern technologies for processing solid waste. The article gives a brief description of the main project stages, a feasibility study, and environmental rationale. It is assumed that the company will provide the following services: collection, pressing and further processing of secondary raw materials, as well as the production of corrugated packaging.
The paper presents data on environmental quality assessment of the state of Siberian spruce needles (Picea obovata) in Kirovsk, Murmansk Region for the period autumn 2019. It is confirmed that the methods of bioindication of the environment using coniferous plants are based primarily on the study of their morphological and structural changes. It was found that the condition of Siberian spruce needles in the study area (Kirovsk, Murmansk Region) is assessed as satisfactory. The average percentage of the area of damaged plants at different sampling points ranges from 1,96 to 2,4%. With the height of the tree, the needles become more susceptible to drying out, which may be due to an increase in the age (aging) of shoots and needles, as well as the action of abiotic factors (wind, precipitation). The dependence of the average percentage of damage on height was not revealed. The main conclusion is that the state of the environment in Kirovsk, Murmansk Region is rated as good. Indicators for assessing the state of the environment in the study areas differ slightly. The obtained data can be used for monitoring the environment of various districts of the Murmansk Region and other areas of Northern latitudes, for making a plan of environmental measures and environmental monitoring of various industrial enterprises of the Murmansk Region.
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.
