“…These represent the organic and inorganic matter that remains in the sample after evaporation at 105 • C, using a stove (BINDER E 28), and 550 • C, using a muffle (P-SELECTA SELECT-HORN), respectively. Toxicity was evaluated by the growth inhibition of Nasturtium officinalis roots, following the procedure described elsewhere [36].…”

In this study, the heterogeneous photosensitized oxidation treatment of winery effluents was optimized using chitosan carriers immobilized with Zn(II) Phthalocyanine tetrasulfonic acid. The influence of main operating parameters such as initial pH, aeration flow rate, photocatalyst load, and concentration of the photosensitizer used in the photocatalysts’ preparation was investigated. Results for chemical oxygen demand (COD) and phenolic content (TPh) removals are presented for each of the tests performed. Best reductions were obtained after 30 min of treatment in natural sunlight at an initial pH of 4.0 and an aeration flow of 2.8 L/min since it allowed reductions of 45% for COD and 73% for phenolic content (TPh). In addition, the possibility of reusing the photocatalysts during several cycles was also assessed, where an acidic initial pH allowed their reuse, being the only pH value studied where the leaching of the photosensitizer was not observed. In these conditions, the same photocatalysts were reused for six reaction cycles, and efficiency started to decrease after the third use. Thus, a greater mass and concentration of photosensitizer contributed to a superior reduction in organic matter. The results show that heterogeneous photosensitized oxidation using sunlight radiation as an energy source is an interesting approach for obtaining reusable water from winery effluents.

“…Garden cress (Lepidium sativum L.) is a recognized sensitive test-plant in bio testing the toxicity of various substrates. Current studies using garden cress reactions are concerned with assessing the toxicity of antibiotics (Tongur and Yildirim, 2015), analgesic drugs (Tongur et al, 2017a), beta-blocker drugs (Tongur et al, 2017b), new derivatives of heterocyclic compounds (Tsekhmister et al, 2012;Tkachuk et al, 2015), urban solid waste compost (Astaraei, 2009), nanoparticles (Jośko et al, 2017;Mielcarz-Skalska and Smolińska, 2018), oil mill wastewater (Dehmani et al, 2020), some shampoos and dishwashing detergents (Ovsyannikova et al, 2015), heavy metals (Szaniszló and Demény, 2018), microplastics (Bosker et al, 2019;Pflugmacher, et al, 2020Pflugmacher, et al, , 2021, in particular polyethylene terephthalate microplastics and acid rain (Pignattelli et al, 2021a, b). Most publications examine the level of seed germination, weight, and size of seedlings as test indicators.…”

Garden cress (Lepidium sativum L.) is a test-plant for studying the toxicity of substrates, which is the basis of phytotesting. Dangerous pollutants are surfactants contained in household chemicals, including cosmetics. The purpose of the work is to investigate the toxicity of cosmetics the micellar water on a phytotest with garden cress and to analyze it for possible effects on human health and the environment. Investigated available in the retail network of Ukraine means for removing makeup and cleansing the skin -micellar water. Seed germination energy (3 rd day), seed germination, and biometric-morphometric parameters (length of roots and aboveground part of seedlings) (5 th day) were determined. The results were processed statistically. It was found that the germination rates of garden cress seeds and biometric indicators of seedlings significantly decrease (by 14-100 %) with the increasing concentration of the studied micellar water. The phytotoxic effect ranged from 49.6 % to 100 %. It is established that the value of the total toxicity index of solutions is from 0.55 (concentration 6.25 %) to 0 (concentration 100 %), indicating an increase in the toxicity of the solution with increasing concentration. Determined that garden cress is a sensitive plant to the studied cosmetic. The obtained data confirm the high efficiency of this test plant for use in biotesting. The phytotest with L. sativum established the lethal effect of this cosmetic product at a concentration of 100 %. Phytotoxicity decreases when the solution is diluted. Given the results of phytotesting and the composition of the cosmetic product, it can be assumed that at a concentration of 100 % it can pose a potential danger to human health. Given the increase in the market of perfumes and cosmetics, the emergence of counterfeit products, we can expect an increase in the impact of cosmetics on the quality of the environment.
