Мы оценили рост и размножение Eisenia fetida Sav. при культивировании на смесях, содержащих листья тополя, собранных в пяти местах Томска (Россия), с различной антропогенной нагрузкой (железнодорожный вокзал, Михайловский парк, речной порт, Университетский парк и пригородный контроль). Через два месяца наибольший прирост биомассы наблюдался в смеси с листьями, собранными в контрольной точке (8,87 г, прирост - 78,5%) и Университетском парке (8,74 г, 70,5%), в то время как наименьший прирост наблюдался в смеси с листьями из речного порта (5,70 г, 39,9%) и Михайловского парк (5,50 г, 43,0%). Количество отложенных коконов было самым высоким в смесях, содержащих листья из контрольной точки (+138%) и Университетского парка (+94,8%), но снизилось в смесях, содержащих листья с железнодорожной станции (-40,9%). Рост молоди был самым высоким в смесях, содержащих листья из Михайловского парка (+33,4 особи). В целом, качество субстрата в менее загрязненных районах способствует лучшему развитию дождевых червей. Полученные данные послужат основой для рационального управления опавшими листьями в городах и обеспечения безопасности производства биогумуса.</p></abstract><trans-abstract xml:lang="en"><p>Urban leaf litter is a potential source of vermicompost, but its possible contamination with heavy metals raises safety concerns for its use. We assessed the growth and reproduction of Eisenia fetida Sav. when cultivated on mixtures containing poplar leaves collected from five locations in the city of Tomsk  (Russia) with varying anthropogenic loads (train station, Mikhailovsky park, river port, University park, and suburban control). After two months, the greatest biomass increase was observed in the mixture with leaves collected from the control point (8.87 g, 78.5%) and University park (8.74 g, 70.5%), while the smallest increase was in mixtures with leaves from the river port (5.70 g, 39.9%) and Mikhailovsky park (5.50 g, 43.0%).</p><p> Cocoon production was highest in mixtures containing leaves from the control point (+138%) and University park (+94.8%), but decreased in mixtures containing leaves from the railway station (-40.9%). Juvenile growth was highest in mixtures containing leaves from Mikhailovsky park (+33.4 individuals). Overall, substrate quality in less polluted areas promotes better earthworm development. The data obtained will serve as a basis for rational leaf litter management in cities and for ensuring the safety of vermicompost production.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Eisenia fetida</kwd><kwd>вермикомпостирование</kwd><kwd>листья тополя</kwd><kwd>органическое удобрение</kwd><kwd>рост дождевых червей</kwd><kwd>размножение дождевых червей</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Eisenia fetida</kwd><kwd>vermicomposting</kwd><kwd>poplar leaves</kwd><kwd>organic fertilizer</kwd><kwd>earthworm growth</kwd><kwd>earthworm reproduction</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Issariyaporn D., Ch'ng H.Y., Jumpen O.
