    Integrated technology of cadmium phytoextraction for soils of urban ecosystems.
    (Polskie Towarzystwo Inżynierii Ekologicznej (PTIE), 2026-03-08) Yakovyshyna, Tetiana; Nester, Anatoliy; Salamon, Ivan; Dzhumelia, Elvira; Hrypynska, Nadiia; Seleznov, Dmytro
    The paper seeks to develop an integrated mechanism for designing a technology of heavy metal phytoextraction from soils to enhance the environmental safety of urban ecosystems affected by anthropogenic impact. Drawing from an analysis of existing remediation methods for soils contaminated with heavy metals, a scheme has been proposed as a multipurpose framework for creating an integrated phytoextraction technology. It incorporates various components aimed at increasing the mobility of heavy metals in soil and their translocation into plants.

    Investigating electrodes for the extraction and utilisation of copper from spent etching solutions
    (Politechnika Lubelska, 2025-03-22) Nester, Anatoliy; Petruk, Roman; Kalda, Galyna; Pashechko, Mykhaylo; Yakovyshyna, Tetiana; Drobot, Olga; Kirchuk, Ruslan
    Today, reagent-based technologies for metal removal from water often fail to achieve the necessary purification efficiency for reuse and result in the accumulation of toxic sludge. This article aimed to test a regenerator for restoring the properties of etching solutions used in printed circuit boards, evaluate the performance of electrodes in depositing dense copper precipitates during etching solution regeneration, and explore the use of recovered copper in repair processes.

    Regenerating Etching Solutions for Circuit Boards while Extracting Copper
    (Journal of Ecological Engineering, 2024-04-24) Nester, Anatoliy; Yakovyshyna, Tetiana; Salamon, Ivan; Sheludchenko, Lesya; Liubynsky, Oleksandr; Romanishina, Olga; Dzhumelia, Elvira
    The examination of sludge derived from electroplating manufacturing, printed circuit board production, and paste-like residue from sludge collectors uncover elevated levels of chromium, nickel, copper, cadmium, and various metals. The considerable saturation of water in the region and diverse soil compositions complicate the identification of suitable waste disposal sites, specifically for electroplating byproducts, limiting available spaces and fostering conditions conducive to soil and water contamination by heavy metal ions. The retention of used etching solutions within industrial facilities contributes to environmental pollution, necessitating substantial expenditures for proper disposal at manufacturing sites. Industrial waste, notably from processes such as printed circuit board etching, represents a significant threat to water quality, encompassing various essential technological processes for the production of diverse electronic equipment serving both civilian and military purposes. This article aims to present research outcomes and conducted experiments geared towards developing eco-friendly equipment. Also, the research delves into specific procedures for obtaining concentrated copper precipitates during the regeneration of etching solutions, with the extraction process reducing the generation of waste in the form of a paste-like structure saturated with water on industrial premises. The treatment of wastewater from etching printed circuit boards can be achieved by establishing a closed production cycle for board manufacturing and extracting copper for industrial applications. Finally, the research strives to design equipment for regenerating used solutions with metal extraction in a form suitable for remelting, contributing as an element to environmental conservation. The results facilitate the establishment of a printed circuit board etching line that incorporates the reuse of spent etching solutions in the manufacturing process. For solution regeneration, it is recommended to utilize a regenerator with a titanium VT1-0 cathode. The outcomes of individual tests provide conditions for regenerating spent etching solutions and utilizing the extracted copper in the national economy.

    Specificities of considering migration capability of heavy metals in assessing ecological hazard of polluting soils of urban ecosystems
    (Politechnika Lubelska – Люблинский технологический университет, 2025-02-14) Яковишина, Тетяна Федорівна; Нестер, Анатолій Антонович; Пашечко, Михайло Іванович; Калда, Галина Станіславівна; Соколан, Юлія Сергіївна; Пегдонь, Ізабела; Yakovyshyna, Tetiana; Nester, Anatoliy; Pashechko, Mykhaylo; Kalda, Galyna; Sokolan, Juliia; Piegdoń, Izabela
    Necessity of assessing how badly are soils of urban ecosystems polluted by heavy metals has been motivated by the growth of technogenic load and awareness of the hazard level. The study aimed to identify and justify the use of an indicator to assess the actual environmental risks of soil contamination with heavy metals in urban ecosystems. This indicator eliminates the influence of soil buffering capacity on metal fixation and considers the migration potential under specific conditions of spatial pollution distribution.

    Функціонування системи охорони праці та безпеки життєдіяльності в промисловості України
    (Хмельницький національний університет, 2025) Нестер, Анатолій; Яковишина, Тетяна; Мітюк, Люмила; Чоловський, Роман; Nester, Anatoliy; Yakovyshyna, Tetiana; Mitiuk, Liudmyla; Holovskij, Roman
    У статті розглянуто особливості функціонування системи охорони праці та безпеки життєдіяльності в промисловості України. Проаналізовано нормативно-правову базу, що регулює охорону праці, зокрема роль державних органів у контролі за дотриманням вимог безпеки. Визначено основні ризики для працівників у промисловому секторі, а також напрями удосконалення системи управління охороною праці. Акцентовано увагу на важливості профілактичних заходів, навчання персоналу, застосування сучасних технологій та засобів індивідуального захисту. Окрему увагу приділено проблемам реалізації безпеки праці в умовах воєнного стану та поствоєнного відновлення промислових об’єктів. Зроблено висновки щодо необхідності комплексного підходу до забезпечення безпечних умов праці та посилення культури безпеки в галузі.
