Versions Notes
Humans and animals may be exposed on a continuous daily basis to a mixture of environmental contaminants that may act on several organ systems through differing mechanisms [1] resulting in adverse consequences. Environmental contamination now constitutes a major global issue with adverse effects on health of the ecosystem and food security. Globally, air pollution alone produces millions of premature deaths annually, predominantly associated with from lung cancer, chronic obstructive pulmonary disease (COPD), asthma, stroke, heart failure, and respiratory infections, according to the World Health Organization (WHO) [2]. It is noteworthy that 99% of humanity breathes air containing contaminants above recommended levels.
In order to mitigate contamination and diminish e our burden of pollutant -related diseases, we need to devise target-specific strategies to prevent or decrease exposure. To that end, risk assessment attributed to exposure to synthetic or and naturally occurring contaminants is necessary and; thus evidence obtained from toxicity studies appears to be of critical importance. Comprehensive efforts need to be undertaken to search for possible underlying mechanisms of action for each pollutant to establish toxic potential and safe limits through both in vitro and in vivo animal testing approaches. This issue focused on environmental pollutants including heavy metals, pesticides, nanoparticles, micro-nanoplastics, indoor air pollutants, pharmaceuticals, and industrial toxicants with effects on human health, risk assessment, and relationship between various diseases and environmental pollutants. Human exposure to environmental pollutants may initiate adverse effects including neurotoxicity, carcinogenicity, infertility, and metabolic disorders. Therefore, research into possible mechanisms of action for environmental contaminants is of critical importance for the well-being of humans and animals [3].
Over the last couple of decades, novel in vitro and in vivo methods and techniques were developed in the scientific discipline genotoxicology, enabling investigators to quantify genotoxicity attributed to exposure to certain compounds [4,5]. Acute or chronic exposure to environmental contaminants is known to be associated with several adverse health conditions, including cancer, impaired immune and reproductive function, as well as imbalanced gastrointestinal microbiota, which regulates a range of host metabolic and immune processes. The aims of this topic are to present a comprehensive overview of different studies carried out with in vivo and in vitro model organisms and the potential risk of environmental pollutants exposure to human health. In this Topic, 20 original articles, 6 reviews and 1 communication were collected, as presented in Table 1 with a particular focus on alcohol-based hand sanitizers, polycyclic aromatic hydrocarbons, monochromatic light pollution, paraben as an endocrine disruptors, heavy metal pollution attributed to antimony and arsenic of mines in the soil, water, and sediments, groundwater with high fluoride, virus transmission from heating, ventilation, and air conditioning systems of urban subways, chronic home radon exposure, organotin compounds, heavy metal pollutants including mercury, lead, cadmium, polypropylene microplastics, ventral body wall defects in chick embryos, microcystin-LR as an aquatic toxin, N-nitroso compounds, methylmercury as a global pollutant, triazine herbicides, persistent organic pollutants, bisphenol A and trace metals, autophagy, nano- and micro-sized polystyrene particles, tributyltin as an environmental contaminant, polybrominated diphenyl ethers, and per- and polyfluoralkyl substances. Most of the examined compounds originated from natural sources, whereas some semi-synthetic derivatives were also identified and discussed. The most recent findings on the effects of compounds and their constituents in treating various toxic outcomes and genotoxicity are discussed. These studies summarize our current knowledge based upon previous in vitro and in vivo research that scrutinized the influence of several environmental contaminants on various mammalian and non-target model organisms at several genetic, cellular, and molecular levels, as well as potential mechanisms underlying toxicity.
Table 1 schematically illustrates the content of this Topic, with all the contributions published in the five participating journals.
