One of the most important environmental requirements is to prevent the release of toxic compounds contained in the combustion products of household waste, including carcinogenic substances. One of the groups of these compounds is polycyclic aromatic hydrocarbons (PAHs): toxic hydrocarbon compounds that are persistent in the environment, which are present in the combustion products of many materials and may also be petrogenic in nature (they are formed during low-temperature processes not related to burning). An important property of PAHs is marker qualities: their presence in the studied objects indicates a certain source of their origin (linked to certain natural or man-made processes). PAH concentration ratios are used in many domestic and foreign studies to identify the source of contamination. However, the boundary values of the indicator ratios used do not always fully unambiguously characterize the source of pollution, and the ratios themselves are informative to varying degrees for different environments and different natural conditions. The purpose of the article is to substantiate the use of PAH indicator ratios for pollution control as a result of incineration of various categories of waste. The materials for the study are the results of analytical determinations of polyarene concentrations in waste incineration products at domestic and foreign thermal recycling facilities. Indicator ratios of PAHs (a method of “environmental fingerprinting” of pollution sources widely known in foreign practice) have been tested for these objects. Using the methods of multidimensional data analysis (the principal component method), the most informative indicator ratios that can be recommended for use have been determined. Identification of the genesis of PAHs makes it possible to control the amount of pollution in the components of natural environments caused by emissions and waste from the combustion of materials, which contributes to a more objective control of anthropogenic loads.</p></abstract><trans-abstract xml:lang="ru"><p>Проектирование и строительство объектов термической утилизации отходов (в том числе в целях получения энергии) сталкивается с рядом ограничений при выборе применяемых технологий. Одно из важнейших экологических требований - предотвращение выбросов токсичных соединений, которые содержатся в продуктах сгорания бытовых отходов, включая канцерогенные вещества. Одна из групп этих соединений - полициклические ароматические углеводороды (ПАУ): стойкие в окружающей среде токсичные углеводородные соединения, которые присутствуют в продуктах сгорания многих материалов, а также могут иметь петрогенную природу (образуются при низкотемпературных процессах, не связанных с горением). Важное свойство ПАУ - маркерные качества: их присутствие в изучаемых объектах свидетельствует об определенном источнике их происхождения (привязано к определенным природным или техногенным процессам). Соотношения концентраций ПАУ используются во многих отечественных и зарубежных исследованиях для идентификации источника загрязнений. Однако используемые граничные значения индикаторных соотношений не всегда в полной мере однозначно характеризуют источник загрязнения, а сами соотношения в различной степени информативны для разных сред и различных природных условий. Цель исследования - обосновать применение индикаторных соотношений ПАУ для контроля загрязнений в результате сжигания различных категорий отходов. Материалы для исследования - результаты аналитических определений концентраций полиаренов в продуктах сжигания отходов на отечественных и зарубежных объектах термической утилизации. Для этих объектов апробированы индикаторные соотношения ПАУ (широко известный в зарубежной практике метод «экологического детектирования» источников загрязнения). С применением методов многомерного анализа данных (метод главных компонент) определены наиболее информативные индикаторные соотношения, которые могут быть рекомендованы для использования. Идентификация генезиса ПАУ позволяет контролировать объемы загрязнений в компонентах природных сред, обусловленных выбросами и отходами при сжигании материалов, что способствует более объективному контролю антропогенных нагрузок.</p></trans-abstract><kwd-group xml:lang="en"><kwd>polycyclic aromatic hydrocarbons (PAH)</kwd><kwd>indicator ratios</kwd><kwd>petrogenic PAH</kwd><kwd>pyrogenic PAH</kwd><kwd>factor analyses</kwd><kwd>waste</kwd><kwd>combustion</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>полициклические ароматические углеводороды (ПАУ)</kwd><kwd>индикаторные соотношения</kwd><kwd>петрогенные ПАУ</kwd><kwd>пирогенные ПАУ</kwd><kwd>факторный анализ</kwd><kwd>отходы</kwd><kwd>сжигание</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Материал подготовлен при финансировании за счет средств темы НИР 202700-0-000.</institution></institution-wrap><institution-wrap><institution xml:lang="en">The material was prepared with funding from the research project 202700-0-000.</institution></institution-wrap></funding-source></award-group></funding-group></article-meta><fn-group/></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Anchugova EM, Markarova MYu, Shchemelinina TN, Volodin VV.
