Arsenic (As) is widely used in the modern industry, especially in the production of pesticides, herbicides, wood preservatives, and semiconductors. The sources of As such as contaminated water, air, soil, but also food, can cause serious human diseases. The complex mechanism of As toxicity in the human body is associated with the generation of free...

Ellagic acid (EA) is a bioactive polyphenolic compound naturally occurring as secondary metabolite in many plant taxa. EA content is considerable in pomegranate (Punica granatum L.) and in wood and bark of some tree species. Structurally, EA is a dilactone of hexahydroxydiphenic acid (HHDP), a dimeric gallic acid derivative, produced mainly by hydr...

Methylmercury (MeHg) is a global environmental pollutant with neurotoxic effects. Exposure to MeHg via consumption of seafood and fish can severely impact fetal neurobehavioral development even when MeHg levels in maternal blood are as low as about 5 μg/L, which the mother tolerates well. Persistent motor dysfunctions and cognitive deficits may res...

The current review provides an up-to-date analysis of scientific data on astaxanthin (ASX) sources and experimental studies on its health benefits as a potent antioxidant in the aging process. ASX is a liposoluble carotenoid nutrient and reddish-orange pigment, naturally synthesized by numerous microalgae, yeasts, and bacteria as secondary metaboli...

Aging is characterized by an imbalance between damage inflicted by reactive oxygen species (ROS) and the antioxidative defenses of the organism. As a significant nutritional factor, the trace element selenium (Se) may remodel gradual and spontaneous physiological changes caused by oxidative stress, potentially leading to disease prevention and heal...

Polyphenols (PPs) are a large group of phytochemicals containing phenolic rings with two or more hydroxyl groups. They possess powerful antioxidant properties, multiple therapeutic effects, and possible health benefits in vivo and in vitro, as well as reported clinical studies. Considering their free-radical scavenging and anti-inflammatory propert...

Background. Plants growing in urban ecosystems are negatively affected by anthropogenic activities associated with environmental pollution. Plant photosynthesis is one of the processes that are particularly affected by environmental conditions, including the presence of pollutants in the atmosphere and soil. However, the dynamics of photosynthetic...

Rapid industrial and technological development has impacted ecosystem homeostasis strongly. Arsenic is one of the most detrimental environmental toxins and its management with chelating agents remains a matter of concern due to associated adverse effects. Thus, safer and more effective alternative therapy is required to manage arsenic toxicity. Bas...

Background. Various modes of transport are among the main sources of environmental pollution with heavy metals and other pollutants. Bryophytes are known to accumulate heavy metals; however, metabolic changes in mosses under conditions of metal accumulation have not been extensively studied. The aim of this article was to analyze the accumulation o...

This paper analyses ecological features of bryophyte species from the territory of the Pohulyanka Forest Park in the city of Lviv, Ukraine. A total of 141 species of bryoflora were analyzed (70 recorded for the first time). In the spectrum of life forms (LF), species with the following LF prevailed in the study area: turf (61 species, 43.3%), mat (...

The study was aimed at investigating the effect of traffic load on the accumulation of heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) by moss gametophytes (Brachythecium rutabulum and Pylaisia polyantha) and aquatic macrophyte Lemna minor in the territory of the city of Lviv (Ukraine). In the course of the study, five sites were selected: site 1...

There is a high risk of mass acute and chronic poisoning by heavy metals because of their high toxicity and their ability to pollute the environment and to penetrate the human body in different ways. Ukraine has a high rate of adverse effects on the environment. Therefore, a search for antitoxins among food plants in the native flora is one of the...
Article

The article is devoted to the analysis of current data on the ecological features and functions of the aquatic macrophytes which are important components of aquatic and wetland ecosystems across the globe. Macrophytes comprise a taxonomically diverse group of macroscopic plants including representatives of vascular aquatic plants, bryophytes, as we...
Article
The influence of soil and climatic conditions and growth biostimulants on the content of biochemical indices of prooxidant and antioxidant processes in the inflorescences of M. recutita plants of cv. “Perlyna Lisostepu” was investigated. The plants were grown on sod-podzolic soil of Precarpathian and dark- gray podzolic medium loamy soil of the Wes...
Article
Lviv region, one of the most urbanized and industrialized regions of Western Ukraine, faces environmental problems, including pollution of surface waters. The study was aimed to investigate the levels of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in the waters of three tributaries of the Western Bug River (Poltva, Rata and Kamyanka), as w...

Contamination of agricultural products with mycotoxins is a widespread phenomenon that is manifested in many countries. Among mycotoxins, which significantly affect human and animal health, aflatoxins produced by Aspergillus micromycetic fungi (mainly A. flavus) are of serious concern because of their high toxicity and carcinogenicity. The aim of o...

Selenium, discovered in 1817 by Jöns Jacob Berzelius, is known as an element with two faces in relation to human health: as a micronutrient essential for life and a potentially toxic trace element. Important biological functions of selenium are associated with selenoproteins that contain it in the form of selenocysteine (Sec), known as the 21st ami...

Iodine is an essential micronutrient for health and maintenance of thyroid function in humans and other vertebrates. The major effects of iodine in the organism are mediated by its action as a structural constituent of thyroid hormones, thyroxine and triiodothyronine, potent regulators of cellular metabolism and growth and development processes. As...

Our research was aimed at determining the level of accumulation of heavy metals (Cr, Mn, Ni, Pb, Zn) in the epiphytic moss Pylaisia polyantha that grows in the urban ecosystem of Lviv city, in areas with different levels of anthropogenic impact. Studies have shown that the concentration of all metals analyzed in Pylaisia polyantha growing in the vi...

Trivalent chromium is essential to normal carbohydrate, lipid and protein metabolism. Chromium is biologically active as part of an oligopeptide—chromodulin—potentiating the effect of insulin by facilitating insulin binding to receptors at the cell surface. With chromium acting as a cofactor of insulin, Cr activity in the organism is parallel to in...
