The development of eco-coronas on agricultural nanomaterials reduces their harmful impact: a review

Microplastics have been found in a wide range of agricultural soils and plants. The majority of investigations on microplastic contamination took place in soil. Microplastic in soil are indeed a source of frustration for crops and agriculture. Soil biophysical characteristic such as density, moisture content, and earthworm relationships with water stable cluster are all affected by microplastics. Microplastics impacts on soil and plants were frequently influenced by the kinds and forms of microplastics (Qi, Ruimin et al. 2020). Humic substances are organic molecules that play an essential role in the formation of humus, the primary organic portion of soil, peat, and coal. We present here the idea of these pollutants as a complex which Humic acid (HU) binds to create eco-corona, altering the density and surface charge of these particles.  As per the review, according on their varieties, amounts, sizes, and forms, microplastics alter soil biophysical and chemical properties whether in a negatively or positively. It highlights whether microplastics may alter crop enzymatic reactions, possibly causing growth inhibition and oxidative damage. Moreover, farmers that have used sewage sludge and composted to fertilize their agricultural land mistakenly apply the microplastic particles contained in these biosolids. Nanoplastics and microplastics have such a better capability to support and desorb harmful substances due to their increased surface area. We integrate diverse analytical methods in a complimentary manner since microplastics investigation is a relatively new subject. In this review, A specific focus on their behaviour in order to reduce pollution in agriculture has been placed on humic acid because of its potential to affect toxicity.
