“…ied. These studies reported delayed and diminished fruit production [89], reduced shoot and root biomass [91], alterations in total plant biomass and root traits, and reduced plant growth [87] at both vegetative and reproductive stages [86]. For people living in rural communities who are reliant on crops for their income, these studies highlight how microplastics may negatively affect their livelihoods by reducing crop production.…”

Rural areas are exposed to severe environmental pollution issues fed by industrial and agricultural activities combined with poor waste and sanitation management practices, struggling to achieve the United Nations’ Sustainable Development Goals (SDGs) in line with Agenda 2030. Rural communities are examined through a “dual approach” as both contributors and receivers of plastic pollution leakage into the natural environment (through the air–water–soil–biota nexus). Despite the emerging trend of plastic pollution research, in this paper, we identify few studies investigating rural communities. Therefore, proxy analysis of peer-reviewed literature is required to outline the significant gaps related to plastic pollution and plastic waste management issues in rural regions. This work focuses on key stages such as (i) plastic pollution effects on rural communities, (ii) plastic pollution generated by rural communities, (iii) the development of a rural waste management sector in low- and middle-income countries in line with the SDGs, and (iv) circular economy opportunities to reduce plastic pollution in rural areas. We conclude that rural communities must be involved in both future plastic pollution and circular economy research to help decision makers reduce environmental and public health threats, and to catalyze circular initiatives in rural areas around the world, including less developed communities.

“…From there, the treated sewage sludge may be transported onto agricultural land due to its fertilizing effects. However, this treated sewage sludge still contains significant amounts of MPs that pass into agricultural land [ 41 , 42 , 43 ]. Corradini et al (2019) carried out research on 31 fields where sewage sludge was used and it was found that with increasing applications of sewage sludge, the content of microplastics in the soil increased non-linearly [ 44 ].…”

Plastic particles smaller than 5 mm, i.e., microplastics, have been detected in a number of environments. The number of studies on microplastics in marine environments, fresh water, wastewater, the atmosphere, and the human body are increasing along with a rise in the amounts of plastic materials introduced into the environment every year, all contributing to a range of health and environmental issues. Although the use of primary microplastics has been gradually reduced by recent legislation in many countries, new knowledge and data on these problems are needed to understand the overall lifecycle of secondary microplastics in particular. The aim of this review is to provide unified information on the pathways of microplastics into the environment, their degradation, and related legislation, with a special focus on the methods of their sampling, determination, and instrumental analysis. To deal with the health and environmental issues associated with the abundance of microplastics in the environment, researchers should focus on agreeing on a uniform methodology to determine the gravity of the problem through obtaining comparable data, thus leading to new and stricter legislation enforcing more sustainable plastic production and recycling, and hopefully contributing to reversing the trend of high amounts of microplastics worldwide.

“…Besides, PVC MPs of sizes less than 0.5 mm had an acute and chronic toxicity on the growth of garden cress (Lepidium sativum) [82,83]. Furthermore, Hernández-Arenas et al [84] studied the effect of sewage sludge containing MPs on the development of tomato plants in term of biomass and lenth for shoot and root, and the stem diameter and tomato production. Tomato plants (Lycopersicon esculentum Mill.)…”

Microplastics (MPs) are pertinacious contaminants which are threatening the delicate balance of the ecosystem. Over the years, various studies have reported the presence of MPs in the marine environment through case studies and reviews, but its presence in the agricultural soils is not fully understood. To date, there exists no standardized methodology for sampling, extraction and characterization of MPs in the agricultural soils. This review aims at encapsulating the different techniques used for sampling and extraction of MPs, and includes the methods employed for identification and quantification of MPs in the soil environment. Flotation method, pressurized fluid extraction and elutriation are some of the different techniques used for MPs extraction that usually influence the characterization step. Visual identification through microscope and scanning electron microscope and chemical identification via Fourier-transform infrared (FITR) and Raman spectrometry, are the main techniques that are used for the identification of MPs. The fate and dispersion of MPs in the agricultural soil are discussed, as well as their interaction with the soil biota. The main findings of this review show that further research is needed on the sampling methods as well as analytical techniques so as to contribute to standardizing MPs characterization in the soil environment, potential toxicity effects along the food chain, and global policies for sustainable development.
