Abstract
The aim of the research was to highlight the influence of industrial water on the germination of seeds and the development of seedlings of Pisum sativum L., so that the impact of these water on the plants may be assessed, in case of accidental spills. The analysis of polluted industrial water indicates the presence of Cr, Fe, Ni, Pb, Cd, Cu, and Zn concentrations higher than CMA, except Cd, which was below the detection limit, and Cu. On leaving the neutralization station, metal concentration was below the CMA, except Pb. The early ontogenetic stages of root development were much more sensitive to water pollution. For the experimental variants where the seeds were immersed in water treated and discharged from the neutralization station, there were no significant differences between the experimental variants, which also confirms the results of the chemical analysis. The metals absorbed by the roots were translocated into the stem, which affected its growth processes. Along with the increased dilution in the polluted water, the average stem length also increased, which was also true of the root growth. Root and stem growth can represent biomarkers of environmental pollution by metals.
