“…For example, Liu et al, 2019c demonstrated how the surface oxidation of PS NPs induced by UV/ozone ageing drastically affected the mobility and contaminant-mobilizing ability. Further, nanoplastics demonstrated the ability to bind different types of contaminants from naphthalene, fullerene, PCBs, PAHs, metals, POPs, glyphosate, perfluorooctane sulfonate to silver (Hu et al, 2020;Velzeboer et al, 2014;Liu et al, 2016;Town et al, 2018;Zhang et al, 2018;Jeong et al, 2018;Wan et al, 2019;Lin et al, 2019b;Ma et al, 2020;Chen et al, 2020;Lin et al, 2011).

“…A recent explosion of studies has demonstrated that PNPs may have lethal and sublethal toxicity effects for organisms from microbes and bivalves to fish and even humans , . Chemical additives and byproducts are also known to leach from PNPs and may present their own toxicological hazards. ,, Compounding the problems associated with the spread of plastic pollution, PNPs can interact with other environmental contaminants, including a variety of heavy metals − and organic compounds like pesticides and pharmaceuticals , . Due to their small size, PNPs have a high surface area-to-volume ratio and are therefore capable of adsorbing and accumulating significant amounts of these other chemical pollutants, and this adsorption may alter the mobility and toxicity of both the PNPs and the adsorbate.…”

The Mobility of Plastic Nanoparticles in Aqueous and Soil Environments: A Critical Review

2020

Plastic nanoparticles (PNPs) are now widely recognized as a significant, and ever increasing, hazard in aquatic and soil environments. These particles, defined here as plastics <1000 nm across their largest dimension, are released into the environment both as primary products and through the degradation of larger plastic waste. They have the potential to be highly mobile, given their small size, which raises concerns about their global spread. Furthermore, PNPs are capable of adsorbing a variety of other pollutants, including heavy metals, pharmaceuticals, and pesticides, and in doing so may increase the mobility of these harmful materials. Dozens of studies focused on the toxicity of PNPs with and without other adsorbed contaminants for organisms from algae to humans have been published in the past few years. It is also critical to understand the transport of these particles in different environments to fully assess the threat that they pose. In this critical review, we discuss the behavior of suspended PNPs in aqueous systems and water-saturated soil/sediment with a particular emphasis on the processes that may alter their mobility. We describe how PNPs of different sizes and surface functionalities interact with the typical constituents of natural solutions, including metal cations, dissolved and particulate organic matter, and inorganic colloids. These variables all affect PNP aggregation in a range of complex, interrelated ways and can ultimately lead to particle sedimentation and removal from the mobile fluid phase. We also discuss the reactive transport of these PNPs, and PNP aggregates, through soils and sediments, during which PNP mobility can be limited by physical straining and/or attachment to the substrate. Finally, we conclude with some suggested future directions for research within this field, particularly the need for direct measurement of PNP abundances and characteristics in real environmental samples, which to date has been severely limited due to analytical challenges. Plastic nanoparticles do present a serious potential threat to the environment and even to human health, and a thorough understanding of the transport and mobility of these pollutants is critical in assessing these risks.

“…Los picos observados a 3,400 cm -1 y 1,600 cm -1 son atribuidos a la absorción de OH-, correspondientes a los grupos hidroxilo y al H2O adsorbido química y físicamente en la superficie de las nanopartículas del medio circundante [30][31]. En el espectro en rojo, además de los picos del TiO2, se observan los asociados a la TC: 1617 cm -1 relacionado a las vibraciones de estiramiento del anillo bencénico, los picos entre 1457 y 1,400 cm -1 relacionados a la presencia de aromáticos, 1,036 cm -1 asociada a las vibraciones de estiramiento del grupo amino y las vibraciones de tensión de los enlaces OH en el intervalo de los 4,000 a 3,500 cm -1 [32][33]. Los resultados sugieren la capacidad de adsorción de TC en la superficie del TiO2-BRR durante la FO.…”

Se sintetizaron nanoflores de óxido de titanio (TiO2) fase rutilo similares a crisantemo sobre la superficie de anillos de borosilicato Raschig (BRRs). La nanoarquitectura jerárquica se investigó usando varias técnicas fisicoquímicas: microscopía electrónica de barrido (MEB), espectroscopia de energía dispersiva (EED), difracción de rayos-X (DRX), espectroscopia infrarroja por transformada de Fourier (IR-TR), espectroscopia de reflectancia difusa (ERD), potencial zeta (ζ). Los TiO2-BRR fueron usados como columna empacada en un reactor fotocatalítico, y evaluada su actividad catalítica en la degradación de un antibiótico bacteriostático: tetraciclina (C22H24N2O8). El fotocatalizador eliminó el 91% del contaminante emergente logrando una eficiencia energética del 68% con una carga optimizada de 75 TiO2-BRR y un pH de 4 a 25 °C; sin variación significativa en al menos tres ciclos de fotodegradación. Esta información se puede utilizar para el desarrollo de fotocatalizadores soportados de TiO2 dirigidos a eliminar contaminantes emergentes, ofreciendo una alternativa viable.
