Rural population of Ukraine mainly consume water from wells and individual wells, which (in the vast majority) are in unsatisfactory technical and sanitary condition. For the estimation of the quality of the spring waters in some settlements of Mostyska district, the seasonal samples of were taken in Mostyska, Malniv, Gusiakiv, Pidhat, Volytsia, Nagirne, and Krukenychi. Biotesting of well water was carried out, water was analyzed according to physicochemical and bacteriological indicators. It was established that toxicity is higher than average in the villages Krukenychi, Gusiakiv, Volytsia and Malniv, and in Mostyska high toxicity. The content of nitrites and phosphates did not exceed the MPC in all investigated waters. The content of nitrates and ammonia in the spring waters of the investigated area exceeded the MPC in most settlements, with the exception of samples from the villages Pidhat and Nagirne. In addition, only spring water from the villages Nagirne and Pidhat meets the bacteriological indicators for the quality of drinking water.

The monograph confirms the urgent need to improve the work with adolescents and young people, their parents and teachers for health promotion and formation of environmental responsibility.This work is undoubtedly useful for scientists as well as for the general public, parents, teachers, civil servants dealing with these issues and social workers.The publication is available in the online version on: main.nuife.org/en/educatorThe publication is assigned a DOI number: dx
An innovative approach based on the effect of bio-mineralization as a response reaction of cells to decrease their damage under stress was applied to Juniperus communis (JC) and JC-based biomaterials (Nefrovil and Immunostan drugs with properties increasing the antioxidant activity and improving the immune system of human organism, respectively). Electron paramagnetic resonance spectroscopy (EPR), also called electron spin resonance (ESR), was used as the main experimental tool for detecting paramagnetic species resulted from the existence of antioxidant activity system, represented by superoxide dismutase with manganese, catalase etc., as well as formation of superparamagnetic iron oxide nanoparticles (SPIONs). The influence of temperature and microwave power on the intensity of EPR signals detected in JC, Nefrovil and Immunostan was examined. Obtained g-factor values of EPR signals from JC shell and seeds as well as from Nefrovil and Immunostan were attributed to the paramagnetic species of Mn (g = 2.0), Fe3O4 SPIONs (g = 2.17…2.60), Fe aggregates (g = 3.22…3.94) and Fe3+ ions (g = 4.3). The EPR signals from SPIONs and Fe3+ ions in Immunostan were found to be fully correlated, showing an additional experimental evidence of the bio-mineralization effect (i.e., transformation of Fe3+ ions to Fe3O4 SPIONs). The results of the EPR study of Fe3O4 SPIONs incorporated into polymer matrix were taken into account in comparative analysis. The results reported in the present work support well self-organization of magnetic nanoparticles in the investigated biomaterials.
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.
