Abstract

Chemical, biological and toxicological parameters of the soils (gray-humus stratozems, or Hortic Anthrosols, and urbostratozems, or Urbiс Technosols) of the Russian Museum’s gardens have been studied (Summer Garden, Mikhailovsky Garden, and Engineering Square). It has been shown that these soils are highly fertile, environmentally sustainable and have a high buffering capacity for pollutants. The content of pollutants (petroleum products, heavy metals, and benzo(a)pyrene) in the soils of the Russian Museum’s gardens exceeds the MAC and APC standards established in the Russian Federation. However, according to biotesting on daphnia, unicellular algae and higher plants, all the soils studied are nontoxic. Water extracts from the studied soils have a reliable stimulating effect on the seeds of higher plants and green algae, boosting their growth by 30–50%. This may be due to the richness of the soil in nutrients and water-soluble humus substances. The results on heterotrophic (microbial) respiration show that the studied soils are characterized by stable and balanced functioning, as well as by high environmental sustainability of the microbial cenosis to anthropogenic impact. There is a need to revisit the relevant standards for the pollutants’ content in urban soils, basing such correction on the assessment of the actual quality and health of soils at different levels of pollution.
