Abstract
Environmental monitoring of recreational areas of settlements (for example, an urban-type settlement - Svetly Yar, Svetloyarsk district of the Volgograd region)
Incoming article date: 14.12.2020Environmental monitoring of recreational areas of settlements allows you to monitor the ecological state of natural objects and identify environmental risks. The purpose of this work was to assess the element composition of aquatic plants (submerged hornwort (Ceratophyllum demersum)) growing in the recreational zone of the settlement - Svetly Yar. Research objectives: selection of aquatic plants; drying plants in natural conditions; Evaluation of plant samples (dry air sample) by mass spectral and atomic emission methods with inductively coupled plasma according to NSAM method No. 512; comparison of the obtained results with clarke ((Kovalsky V.V., 1974; Market B., 1992); evaluation of the results and prediction of the ecological situation. Research methods. Evaluation of plant samples was carried out by mass spectral and atomic emission methods with inductively coupled plasma according to NSAM method No. 512. Research results. The chemical composition of aquatic plants was studied: submerged hornwort (Ceratophyllum demersum) growing in the lake of the recreational zone near the village. Light Yar. In aquatic plants (dry air sample), on average, an increased content of lithium (Li-88.6 g / t) was revealed - 600 times; tin (Sn-14.9 g / t) - 57 times; sodium (Na-20065 g / t) - 30 times, and others compared to clarke (Kovalsky V.V., 1974; Market B., 1992). Conclusion. The results obtained indicate the pollution of the water body and environmental risks for the living population when organizing recreation. An assumption is made about a natural source of pollution. It comes from the buried ancient magma of the paleovolcano in the steppe, which saturates the groundwater with chemical elements that feed the recreational lake. Further research and a comprehensive study of the territory of the village is required. Svetly Yar and its environs with the aim of confirming or refuting the hypothesis of the natural origin of the revealed chemical elements of hurricane values in comparison with clarke.
