Living organisms are continuously exposed to environmental pollutants. Because of its critical location, the skin is a major interface between the body and the environment and provides a biological barrier against an array of chemical and physical environmental pollutants. The skin can be defined as our first defense against the environment because of its constant exposure to oxidants, includin...
In recent years there has been a growing concern all over the globe, about marine pollution due to persistent organic pollutants. Sediments, which are an important component of marine environment can serve as sorbents or concentrators for various persistent organic pollutants, including Polychlorinated Biphenyls (PCBs). In this study, the depth profile of accumulated PCBs in Thane Creek sedimen...
This contribution regards three fundamental aspects of the urban pollution, sources, diffusion and chemical composition with relative speciation, pointing out the anthropogenic activities and their relationship with the environmental sustainability. The chemical parameters ruled by laws (conventional pollutants) are evidenced together with other species not ruled (no conventional pollutants) bu...
Many international efforts have been spent to eliminate and/or reduce the emissions and discharges of a wide range of pollutants that have persisted in the environment as well as living organisms [1]. These pollutants are known as a persistent organic pollutants (POPs). Contamination from POPs is a pervasive global problem that urgently demands a global solution [2]. These chemicals include org...
One of the main global ecological problems is contamination of the natural environment by persistent organic pollutants (POPs). Polichlorinated biphenyls (PCBs) is a group of compounds that belongs to this family of pollutants. Poland, as a European Union member and signatory of international agreements concerning environmental protection, is obliged to regulate the law and intensify work on th...
The term “pollutant emergent” refers to any type of contaminant originated from previously undetected or products that were not problematized in health and environment [1]. In this group of pollutants has a product for veterinary use, personal care products, and pesticides. The pharmaceuticals in the aquatic environment should be highlighted by reaching the environment through discharges or exc...
Introduction: Air pollution is one of the hazardous factors on human health and the environment. In the zinc production industry, because of process nature and using electrolysis pools, the amount of production and diffusion of some of the harmful pollutants such as acidic vapors is exceedingly high. This study aimed to assess the effectiveness of push-pull ventilation system implemented for co...
Strictly speaking, all toxins entering the environment can be regarded as environmental poisons. Certain pollutants can, acting over long periods, harm living organisms even in low concentrations. This means that pollutants that are stable and thus persistent have a great ability to act as environmental poisons. Their stability means not only that their effects are long-lasting, but also that t...
