The international hazard classification for chemical substances and mixtures affecting the reproductive system covers also adverse developmental effects via lactation, along with assessment of their adverse effects on the male and female sexual function and fertility. Toxicological characteristics are reported that present hazard to breastfed children and are regulated at the domestic and international levels.
The results of our own and foreign studies have shown the absence of sensitizing properties of terephthalic acid, and therefore there was a need to review the current hygienic standard – MAC – in the air of the working area and change the hazard class of the substance. The materials of the German Research Community (DFG) were used for substantiation of MAC. Recommended MAC in the air of working area is set at 5 mg/m3 (maximum single), a mixture of vapors and aerosol, hazard class 3.
The article presents an overview of current issues of international regulation of the content of heavy metals (lead, cadmium, mercury and arsenic) in food. Special attention is paid to the revision of the standards for the content of arsenic in rice, mercury in some types of fish, cadmium in chocolate, lead in meat, offal, and wine. A comparative analysis of the standards -permissible levels of content of heavy metals in food products in the EU and the Russian Federation is carried out.
Currently, perfluorooctanoic acid (PFOA) has no hygienic standards in the air of the working area and objects of the human environment in the Russian Federation. By the decision of the Stockholm Convention SC-9/12, PFOA, its salts and derivatives are included in Part I of Annex A of the Stockholm Convention on Persistent Organic Pollutants in 2019 (with exceptions for possible use). The Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade included PFOA, its salts and derivatives in the list of potential candidates for inclusion in Annex III of the Rotterdam Convention at the next meeting COP10 in 2021. The use of this chemical on the territory of the Russian Federation entails water and air pollution. Industrial emissions and waste water from fluoropolymer production, thermal use of materials and products containing polytetrafluoroethylene, biological and atmospheric degradation of fluorotelomer alcohols, waste water from treatment facilities are the sources of the release of PFOA into the environment. Analysis of international databases has showed that PFOA is standardized in the air of the working area in Germany, Japan, and Switzerland. In the countries of the European Union, as well as the USA and Canada, the issue of PFOA standardizing in drinking water is being now actively under discuss. Taking into account the high toxicity and hazard of the substance and the serious concern of the civil society of the Russian Federation, the Federal Service for Supervision of Consumer Rights Protection and Human Wellbeing requested the Russian Register of Potentially Hazardous Chemical and Biological Substances to develop MACs for perfluorooctanoic acid in the air of the working area and water as soon as possible. The MACs for PFOA have been proposed using risk analysis: 0,005 mg/m3, aerosol, hazard class 1 – in the air of the working area and 0,0002 mg/L, the limiting hazard indicator – sanitary-toxicological, hazard class 1 – in the water.
Introduction. The problems of the impact of endocrine disruptors on human health and the environment are of serious concern today at the international, regional and national levels. Although the first mention about an ability of a substance to harm the endocrine system back in the 60 th of the XX century, the issues of substantiating the criteria for classifying it as endocrine disruptors, identifying potential disruptors of the endocrine system, assessing and classifying their danger to health and the environment with the purpose of further regulation. The aim of the study. To study of world experience in classifying chemical compounds as endocrine disruptors; creating a list of chemicals circulating on the territory of the Russian Federation that can potentially affect the endocrine system; selection of criteria for their classification according to the degree of hazard. The material for the analysis was literature sources from the bibliographic databases Web of Science, MedLine, EMBASE, Global Health, PubMed, Scopus, RSCI. The documents of international organizations, the European Union, the USA, Canada, Japan, India and other states on the hazard assessment, classification and regulation of endocrine disruptors have been studied and analyzed. Considering international experience, the criteria for classifying chemical compounds as endocrine disruptors have been substantiated, including three main components: an adverse effect on the body, an endocrine mechanism of action, and a biological relationship between endocrine activity and an adverse effect. A comparative analysis of the hazard classifications of endocrine disruptors developed by the EU and India showed to be based on the principles of the Globally Harmonized System of Classification and Labeling of Hazards of Chemicals and Mixtures. Considering the limited scientific knowledge about substances capable of destroying the endocrine system, it is advisable to introduce class 3 for substances with limited data obtained in “in vitro” experiments in invertebrates tests. Conclusion. International approaches to the selection, assessment and classification of chemicals that have a potential impact on the endocrine system will allow for the first time in the Russian Federation to form a national list of endocrine disruptors, to identify substances that are the priority in terms of hazard and degree of risk for making relevant management decisions.
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.
