“…At the same time, phytoremediation is one of the most suitable and effective methods for removing AN from wastewater [4,7]. Inorganic nitrogen is also represented by nitrates (NO 3 − ) and nitrites (NO 2 − ), and as the latter presents higher toxicity to aquatic life forms, it can also be remediated [8][9][10].…”

Phytoremediation is an effective method used to control the accumulation of certain contaminants found in industrial or city wastewater. Among the species with high efficacy are Eichhornia crassipes (water hyacinth), Lemna minor (common duckweed), and Pistia stratiotes (water lettuce). In this study, the application of these species in the context of two municipal wastewater treatment facilities in Cluj County, Romania, is evaluated. To determine the efficacy of bioaccumulation, we measured the content of nitrogen species (ammoniacal nitrogen, nitrites, and nitrates), phosphorous, iron, and chromium before and after the addition of plant material to effluent and treated wastewater. The results showed that E. crassipes, L. minor, and P. stratiotes presented high phytoremediation yields for these common wastewater pollutants after one week of contact, with yields as high as 99–100% for ammoniacal nitrogen, 95% for phosphorous, 96% for iron, and 94% for chromium. However, the remediation capacity for nitrate and nitrite was less significant.

When rehabilitating technogenically disturbed lands of mining facilities, fertilizers and ameliorants are to be applied due to the lack of organic matter and nutrients required for the restoration of the soil and vegetation layer. The use of unconventional fertilizers (ameliorants) based on sewage sludge is one of the actual directions of land reclamation at mining sites. The purpose of the work is to summarize and analyze up-to-date information on the effectiveness of the use of sewage sludge for the reclamation of technogenically disturbed lands of mining and processing industries. The analysis is based on a review of recent studies aimed at assessing the impact of introduced sediment on soils, plant communities, and rehabilitated areas. The introduction of sewage sludge has a positive effect on the physical and chemical parameters of the soil (optimizes density and aggregation), saturates it with nutrients, i.e. N, P, K, Ca, Mg, and Na, thus improving plant growth indicators. However, it may contain a number of heavy metals and pathogens; therefore, studies of each sediment and conditions of reclaimed areas are necessary.
