The total mineral content was studied in medicinal plants from roadside and railside biotopes of the Voronezh region. Pharmacopoeial plant raw materials of 10 species were evaluated: roots of Taraxacum officinale F.H. Wigg and Arctium lappa L.; herb of Polygonum aviculare L., Artemisia absinthium L., Leonurus quinquelobatus Gilib., and Achillea millefolium L.; leaves of Urtica dioica L. and Plantago major L.; and flowers of Tanacetum vulgare L. and Tilia cordata Mill. Plant raw materials were collected near roads and railways of various types in the periods specified in regulatory documents. The total ash content in plant material was used to determine the minimum allowable distances from various roads and railways for collecting plant material. The minimum allowable distance from heavy-traffic motorways was recommended to be 210 m in the forest zone, 240 m in the forest-steppe zone, and 380 m in the steppe zone. A distance of at least 80 m was recommended for secondary low-speed roads and railways. [ABSTRACT FROM AUTHOR] |
