Аннотация: The treatment of coal mine wastewater, as well as the reclamation of depleted coal mines, are seriousenvironmental problems. One of the ways to solve them is phytoremediation using stress-resilient plantssuch as the common pine (Pinus sylvestris L.). To mitigate the risk of epiphytotics during mass cultivation,treatments with chemical pesticides are necessary. It is important to make sure that the pesticides do not harmplants when using coal mine wastewater containing heavy metals for irrigation. In this regard, mass monitoringof plants by non-invasive methods is highly relevant. In this work, we used direct measurement methodsand a non-invasive approach based on hyperspectral imaging to comprehensively monitor the condition ofpine seedlings treated with the Actara™ and Previcur Energy™ pesticides in different concentrations (single,double, and quadruple compared to the concentration recommended by the manufacturer) and irrigated withthe solutions of mineral salts simulating the wastewater from coal mines. It is shown that, despite some methodologicaldifficulties, it is possible to use hyperspectral images for non-invasive remote monitoring of thecondition of coniferous seedlings in vegetation experiments, including in the field. It was found that the pesticidetreatments exerted neither acute toxicity nor a pronounced negative effect on the growth rate and pigmentcomposition of the pine seedlings during the two-month observation. At the same time, irrigation ofthese plants with model Coal mine wastewater also did not produce synergistic toxic effects. Thus, there areno obvious obstacles to the use of the above-mentioned pesticides for treatment of Scots pine seedlings irrigatedwith Coal mine wastewater containing Fe, Zn, and Mn. The results obtained also support the use ofwastewater rich in mineral nutrition elements but lacking highly toxic heavy metals (such as Pb and Cd), whengrowing plants for phytoremediation of soils from depleted coal mines. However, long-term, preferably multiyearstudies are needed to assess long-term risks.
