Nano-Iron Oxide (Fe3O4) Mitigates the Effects of Microplastics on a Ryegrass Soil–Microbe–Plant System

“…The numerous applications of plastics, mainly due to their flexible surfaces and lightweight nature, have greatly boosted plastic production since 1950 to the current manufacture of more than 12.5 million tons annually. , The prevalent use of plastics is projected to generate around 12 billion tons of plastic debris by 2050, and this is likely to lead to severe environmental issues. , Microplastic (MP) particles of synthetic organic polymers with sizes <5 mm have emerged as dangerous pollutants since 1980, and much attention has been paid to the MPs and their relevant health issues. , MPs with different shapes and morphologies such as pellets, fibers, foams, and films have been reported to spread in the atmosphere, terrestrial, aquatic, and soil environments, posing a threat to living beings. , Therefore, MP contamination has been intensifying/escalating rapidly, gaining a lot of research attention and generating the need to understand the impact of MPs on terrestrial environments, especially agriculture. Although the use of plastic in agriculture initially promoted food security worldwide, today it is well-known that it has left a pollution legacy, as MPs threaten food production systems …”

Assessing the inconsistency of microplastic measurements in foods and beverages

“…On the other hand, Pham et al (2023) claimed that identifying only the selected particles with FTIR (Muhlschlegel et al, 2017) led to an underestimation of the MP contamination in honey. In addition, although the abundance of MP contamination in honey samples was determined to be 0.52 ± 0.29 MPs/g (Pham et al, 2023), it was believed that the results of just six products in this study were insufficient to establish an appropriate risk assessment in honey. Fluorescent dyes, Rose Bengal, and Nile Red, are used to distinguish plastic and non-plastic particles in microscopic analysis, but they also cause erroneous results (false positive or false negative) in some studies.…”
