The objective of this study was to analyze the key approaches to the hygienic regulation of biocidal products for water treatment in the EU and Ukraine to prevent their adverse effects on human health. The study graphically presents the classification of biocides used for water treatment, outlines challenges in implementing European requirements for their hygienic regulation and highlights the necessity of defining safe and optimal conditions for their use. It concludes that it is currently relevant to improve Ukrainian legislation concerning the procedure for the state registration of biocidal products, taking into account the requirements of EU Regulation No. 528/2012 of 22 May 2012 on the making available on the market and use of biocidal products — particularly those intended for drinking water treatment — and the quality standards for drinking water under Directive 2020/2184/EU on the quality of water intended for human consumption. These improvements will contribute to the implementation of stricter requirements for the composition and properties of biocidal products for water treatment, promote the dissemination of more efficient water purification technologies, reduce microbiological risks, and protect human health.
