“…From an ecotoxicological perspective, MPs have the peculiar characteristic to combine a physical stress with a chemical challenge (Pittura et al, 2018). The chemical impact is mostly related to additives present in the plastic from manufacturing, as well as, to the environmental contaminants which can be adsorbed by the hydrophobic nature and high surface-to-volume ratio of MPs/NPs (Atugoda et al, 2021). Pollutant-plastic interaction depends on properties of both MPs/NPs and chemical contaminants and can be modulated by the surrounding environmental conditions of pH, salinity and temperature (Menéndez-Pedriza and Jaumot, 2020).…”

“…This will impact negatively on the natural ecological activities of these organisms, such as litter decomposition, nutrient cycling and energy flow, posing various potential environmental and health hazards (Wang et al, 2020). Furthermore, due to their high surface area-to-volume ratio and hydrophobicity, MNPs might act as transporters of pathogens and organic pollutants on land, similar to previously highlighted in aquatic habitats (Atugoda et al, 2021). Also, microorganisms attached to MNPs represent a threat to the environment by acting as a conduit for MNPs to be transferred from the soil to plants and, eventually, to other living beings via the food chain (Chai et al, 2020).…”

Environmental Impacts of Microplastics and Nanoplastics: A Current Overview

The increasing distribution of miniaturized plastic particles, viz. microplastics (100 nm–5 mm) and nanoplastics (less than 100 nm), across the various ecosystems is currently a subject of major environmental concern. Exacerbating these concerns is the fact that microplastics and nanoplastics (MNPs) display different properties from their corresponding bulk materials; thus, not much is understood about their full biological and ecological implications. Currently, there is evidence to prove that these miniaturized plastic particles release toxic plastic additives and can adsorb various chemicals, thereby serving as sinks for various poisonous compounds, enhancing their bioavailability, toxicity, and transportation. Furthermore, there is a potential danger for the trophic transfer of MNPs to humans and other higher animals, after being ingested by lower organisms. Thus, this paper critically analyzes our current knowledge with regard to the environmental impacts of MNPs. In this regard, the properties, sources, and damaging effects of MNPs on different habitats, particularly on the biotic components, were elucidated. Similarly, the consequent detrimental effects of these particles on humans as well as the current and future efforts at mitigating these detrimental effects were discussed. Finally, the self-cleaning efforts of the planet via a range of saprophytic organisms on these synthetic particles were also highlighted.

“…Data on the adsorption of pharmaceutical residues on the MPs surface are quintessential for risk and environmental assessment. Several studies showed that the desorption rates of polyethylene MPs increased in the order of propranol, sulfamethoxazole, and sertraline, which were associated with the increment of the adsorption capacity and the hydrophobicity [21]. In addition, Lin et al [41] revealed that marine and warm-blooded organisms are at higher toxicity exposure to atorvastatin, amlodipine, and tetracycline even at a lower concentration due to their chronic degradation and metabolites, which is in contrast to organisms that are cold-blooded.…”

“…The hydrophobic/hydropholic nature of pharmaceutical compounds facilitates their interaction with microplastics, frequently present in surface water and playing the role of a vector of pharmaceuticals within aqueous environments through π-π interactions [21]. The literature cites about 160 pharmaceutical compounds that have been recently found in the water surface and wastewater [21]. There are already approaches and strategies for minimizing this issue that proved their efficiencies and estimates to be implemented and prioritized in the near future.…”

Removal of Pharmaceuticals from Water by Adsorption and Advanced Oxidation Processes: State of the Art and Trends

Pharmaceutical products have become a necessary part of life. Several studies have demonstrated that indirect exposure of humans to pharmaceuticals through the water could cause negative effects. Raw sewage and wastewater effluents are the major sources of pharmaceuticals found in surface waters and drinking water. Therefore, it is important to consider and characterize the efficiency of pharmaceutical removal during wastewater and drinking-water treatment processes. Various treatment options have been investigated for the removal/reduction of drugs (e.g., antibiotics, NSAIDs, analgesics) using conventional or biological treatments, such as activated sludge processes or bio-filtration, respectively. The efficiency of these processes ranges from 20–90%. Comparatively, advanced wastewater treatment processes, such as reverse osmosis, ozonation and advanced oxidation technologies, can achieve higher removal rates for drugs. Pharmaceuticals and their metabolites undergo natural attenuation by adsorption and solar oxidation. Therefore, pharmaceuticals in water sources even at trace concentrations would have undergone removal through biological processes and, if applicable, combined adsorption and photocatalytic degradation wastewater treatment processes. This review provides an overview of the conventional and advanced technologies for the removal of pharmaceutical compounds from water sources. It also sheds light on the key points behind adsorption and photocatalysis.
