“…Aquatic plants growing in metal-contaminated waters are able to accumulate heavy metals [62]. Besides the negative effect on plant growth, metal contamination also causes oxidative stress, as reported for duckweed exposed to Cd, Cu, Cr, and Hg [63,64]. Oxidative stress in aquatic plants can be detected by increased activity of antioxidative enzymes, malondialdehyde, or changes in total carotenoids content [64,65].…”

Recycling of materials such as masonry or concrete is one of the suitable ways to reduce amount of disposed construction and demolition waste (CDW). However, the environmental safety of products containing recycled materials must be guaranteed. To verify overall environmental benefits of recycled concrete, this work considers ecotoxicity of recycled concrete, as well as potential environmental impacts of their life cycle. Moreover, impacts related with carbonation of concrete is considered in terms of durability and influence of potential CO2 uptake. Concrete containing fine recycled aggregate from two different sources (masonry and concrete) were examined experimentally at the biochemical level and compared with reference samples. Leaching experiments are performed in order to assess physicochemical properties and aquatic ecotoxicity using water flea, freshwater algae and duckweed. The consequences, such as effects of material on soil enzymatic activity (dehydrogenase activity), photosynthetic pigments (chlorophylls and carotenoids), and the carbonation process, are verified in the laboratory and included in the comparison with the theoretical life cycle assessment. As a conclusion, environmental safety of recycled concrete was verified, and its overall potential environmental impact was lower in comparison with reference concrete.

“…Environmental pollution due to the toxic metals has been on the rise since the industrial revolution, leading to serious ecological problems [1,2]. Several studies were conducted over the last two decades on macrophytes removing the heavy metals from the polluted water [3][4][5]. These macrophytes include the water ferns (Salvinia molesta, Salvinia auriculata, Salvinia minima), water lettuce (Pistia stratiotes), water hyacinth (Eichhornia azurea, Eichhornia diversifolia, Eichhornia paniculata), and duckweed (Lemna minor) [3,6].…”

The aim of this study is to explain the biological response and rhizofiltration capacity of Pistia stratiotes, which is an aquatic macrophyte, in alleviating heavy metal stress. In our study, Pistia species were exposed to Nickel (Ni) at different concentrations over seven days. The potential of the aquatic macrophytes in accumulating heavy metals in the water and in removing them from the environment was evaluated by determining the bio-concentration factors (BCF). Selected biological parameters in the leaves of Pistia stratiotes, including metal accumulation, photosynthetic pigment amount, lipid peroxidation activity, and growth rates were measured at the end of the seven-day period. The highest amount of Ni accumulation in P. stratiotes occurred at a concentration of 20 mg l -1 . The amount of chlorophyll a (chl a) in P. stratiotes reached a value of 0.087 mg g -1 at the Ni concentration of 20 mg l -1 . The relative growth rate (RGR) of P. stratiotes showed a negative correlation with the increases in the concentration levels of the metal. Malondialdehyde (MDA) levels increased to 8.214 nmol/g at the concentration of 20 mg l -1 , depending on Ni concentration and time. In our study, the use of P. stratiotes has been determined to be an appropriate plant as an effective Ni accumulator to be utilized with the purpose of rhizofiltration.

High-Performance Concrete Mixtures Containing Glass Powder: Optimization of mechanical properties, durability, and environmental impacts for use in construction and design applications

This thesis focuses on the use of glass powder from various sources. These are mainly waste glass that comes from shards from municipal waste and old glass from photovoltaic panels due to the end of the service life of these systems from the first generation. Another type of glass investigated is a secondary product of glass production. By-products are created in many branches of industry; the glass industry is a significant producer in this respect. Two types of glass from different glass plants were analyzed. The initial study was already published in 2019 and was among the first in the Czech Republic; therefore, it was desirable to follow up with further research. Since the use of glass powder in concrete, in addition to the possibility, raises many fundamental questions, this research analyzes the materials as such, especially from the chemical, physical and toxic points of view. Repeated experiments were carried out in the thesis, and concrete samples with these materials were subsequently tested. The main point of interest was verifying the potential alkali-silica reaction (ASR), which was assumed due to the use of glass, which can catalyze the reaction. ASR testing took place in two iterations, international and national testing procedures were chosen. The potential ecotoxic threat of glass was viewed similarly significantly. Glass from photovoltaic panels and glass as a secondary production product was slightly hazardous in toxicity tests. However, after encapsulation in concrete, all results were at safe levels below the limit. Due to the subsequent development of tiles and masonry applications, it was necessary to test these potentially undesirable properties thoroughly. Thus the assumption of a positive effect of glass powder on the concrete mixture in terms of ASR and toxicity was confirmed for most mixtures. At the same time, a methodology was proposed for the evaluation of building materials from the point of view of ecotoxicity.
