“…Finally, we introduce a systematic approach for explicit nanoplastic particle detection to bridge the well-known methodological gap of detection and quantification of nPp from the environment 15 . We qualified the substrate performance to bind colloidal plastics via surface interactions by comparing the experimental surface coverage to the theoretical maximum coverage.…”

Microplastics accumulate to various aquatic organisms causing serious health issues, and they have raised concerns about human health by entering our food chain. The recovery techniques for the most challenging colloidal fraction even for the analytical purposes are limited. Here we show how hygroscopic nanocellulose network acts as an ideal capturing material even for the tiniest nanoplastic particles. We reveal that the entrapment of particles from the aqueous environment is a result of the network’s hygroscopic nature - a feature which is further intensified with the high surface area. We determine the nanoplastic binding mechanisms using surface sensitive methods, and interpret the results with the random sequential adsorption (RSA) model. The microplastic uptake does not rely on any specific interfacial interaction but rather on the water transport behavior of nanocellulose. These findings hold potential for the explicit quantification of the microplastics from different environments, and eventually, provide solutions to collect those directly on-site where they are produced.

“…Complex changes, contamination and variations related to size, shape and chemical makeup have made it difficult for the standardized experimental analysis of microplastics [57]. Before tissues are subjected to analysis for microplastics identification, the tissues are first digested to obtain the microplastics.…”

Technological advances, coupled with increasing demands by consumers, have led to a drastic increase in plastic production. After serving their purposes, these plastics reach our water bodies as their destination and become ingested by aquatic organisms. This ubiquitous phenomenon has exposed humans to microplastics mostly through the consumption of sea food. This has led the World Health Organization (WHO) to make an urgent call for the assessment of environmental pollution due to microplastics and its effect on human health. This review summarizes studies between 1999 and 2020 in relation to microplastics in aquatic ecosystems and human food products, their potential toxic effects as elicited in animal studies, and policies on their use and disposal. There is a paucity of information on the toxicity mechanisms of microplastics in animal studies, and despite their documented presence in food products, no policy has been in place so far, to monitor and regulates microplastics in commercial foods meant for human consumption. Although there are policies and regulations with respect to plastics, these are only in a few countries and in most instances are not fully implemented due to socioeconomic reasons, so they do not address the problem across the entire life cycle of plastics from production to disposal. More animal research to elucidate pathways and early biomarkers of microplastic toxicity that can easily be detected in humans is needed. This is to create awareness and influence policies that will address this neglected threat to food safety and security.

“…The first steps(s) in analyzing plastic from environmental samples usually comprises of different separation and/or purification procedures. Separation frequently consists of passing samples through sieves or filter membranes (Fu et al, 2020). The purification process commonly involves treatment with, for example, ethanol (Zettler et al, 2013;Dussud et al, 2018), purified sea water (Dussud et al, 2018), or strong acidic and/or alkaline solutions (Cole et al, 2014;Imhof et al, 2016).…”

Antimicrobial resistance (AMR) is a global health threat. Antibiotics, heavy metals, and microplastics are environmental pollutants that together potentially have a positive synergetic effect on the development, persistence, transport, and ecology of antibiotic resistant bacteria in the environment. To evaluate this, a wide array of experimental methods would be needed to quantify the occurrence of antibiotics, heavy metals, and microplastics as well as associated microbial communities in the natural environment. In this mini-review, we outline the current technologies used to characterize microplastics based ecosystems termed “plastisphere” and their AMR promoting elements (antibiotics, heavy metals, and microbial inhabitants) and highlight emerging technologies that could be useful for systems-level investigations of AMR in the plastisphere.
