“…These compounds can be transported across cell membranes, causing them damage and increasing their permeability, which consequently leads to the inhibition of plant growth [55]. In addition, PAHs have been shown to interfere with the process of photosynthesis, which first leads to inhibition of plant growth and then plant death [56,57]. Daresta et al [58] observed a decrease in the growth of tomato seedlings and an increase in the level of ROS in plant cells exposed to atmospheric PAHs.…”

One method of managing used car tires is decomposition by thermochemical conversion methods. By conducting the process at temperatures of 450–750 °C, three fractions are obtained from tires: oil, gas, and solid. The liquid product of the pyrolysis of used car tires is pyrolysis oil, which consists of aromatic, polyaromatic, and aliphatic hydrocarbons. Unconventional building materials were obtained from tire pyrolysis oil and the environmental impact was evaluated. Blocks made from pyrolysis oil showed mechanical strength of up to about 1700 N. No heavy metals or polycyclic aromatic hydrocarbons, which were found in the crude heavy-PO fraction, were detected in the filtrates after incubation of the block obtained from the heavy-PO fraction at 240 °C. The highest inhibition of Sorghum saccharatum shoot (74.4%) and root (57.5%) growth was observed for solid materials from the medium-PO fraction obtained at 240 °C. The most favorable values of the parameters for the process of obtaining blocks based on post-PO were an annealing temperature of 180 °C, time of 20 h, and mass ratio of catalyst to catalyzed oil of 0.045.

“…Photosynthesis is a fundamental biochemical process based on the conversion of light energy into chemical energy. Photosynthetic organisms possess several protein complexes associated with chloroplasts and thylakoid membranes essential for the light reactions—e.g., photosystems I and II (PSI, PSII) and cytochrome b 6 f [ 40 ]. Presumably, the most sensitive and primary site of inhibition caused by environmental pollution is photosystem II—an enzyme complex located in the thylakoid membrane in cyanobacteria and algae [ 41 ].…”

Antibiotic residues have been commonly detected worldwide in freshwater, estuarine, and marine ecosystems. The review summarizes the up-to-date information about the toxic effects of over 60 antibiotics on nontarget autotrophic microorganisms with a particular focus on marine microalgae. A comprehensive overview of the available reports led to the identification of significant knowledge gaps. The data on just one species of freshwater green algae (Raphidocelis subcapitata) constitute 60% of the total information on the toxicity of antibiotics, while data on marine species account for less than 14% of the reports. Moreover, there is a clear knowledge gap regarding the chronic effects of antibiotic exposure (only 9% of studies represent exposition time values longer than 7 days). The review summarizes the information on different physiological endpoints, including processes involved in photosynthesis, photoprotective and antioxidant mechanisms. Currently, the hazard assessment is mostly based on the results of the evaluation of individual chemicals and acute toxicity tests of freshwater organisms. Future research trends should involve chronic effect studies incorporating sensitive endpoints with the application of environmentally relevant concentrations, as well as studies on the mixture effects and combined environmental factors influencing toxicity.

“…These substances can be found in air, water, and soil and the difficulty in their removal is due to the fact that they are subject to biological, chemical, physical, and photochemical processes. A high load of organic substances is found in municipal wastewater, wastewater from the paper industry, pharmaceutical industry, tanning industry, food industry and agriculture, among others [2][3][4]. Of particular importance is wastewater from the pharmaceutical industry as it may contain a mixture of active substances that have strong effects on the health and life of living organisms, and, in addition, mixtures of these substances may have different effects from individual forms.…”

Sustainable development and environmental protection are among the most important challenges facing humanity today. One important issue is the problem of groundwater and surface water pollution which can lead to the degradation of aquatic ecosystems and negatively affect human health. As a result, new methods and materials are being sought that can help remove contaminants from water in an efficient and environmentally friendly manner. In recent years, there has been increasing interest in composite materials made from used cooking oil. This paper presents attempts to obtain composite materials with the addition of nano-sized zinc oxide and titanium oxide. The characterization of the composite materials was performed using FTIR, XRD, and SEM-EDS; their sorption and photocatalytic abilities were studied using batch mode experiments. The materials obtained exhibited sorption and photocatalytic properties. The highest value of photodegradation efficiency of more than 70% was recorded for the oil composite containing 20% zinc oxide. Composites containing 10% zinc oxide and titanium oxide had comparable sorption efficiencies of about 45% but different photodegradation efficiencies of 0.52% and 15.42%, respectively.
