“…MPs can enter soils through various pathways, including sewage and sludge irrigation and residual mulching film decomposition [ 23 , 24 ]. An increased amount of MPs in the soil can directly alter the soil physicochemical properties, leading to reduced soil aeration, increased erosion, altered soil pH, and reduced nutrient availability for plants, and, hence, lower crop yields [ 25 , 26 ]. Additionally, the presence of MPs may alter the composition of soil microbial communities, reducing the diversity and abundance of beneficial microorganisms, which play essential roles in soil fertility and plant growth.…”

Plastics have inundated the world, with microplastics (MPs) being small particles, less than 5 mm in size, originating from various sources. They pervade ecosystems such as freshwater and marine environments, soils, and the atmosphere. MPs, due to their small size and strong adsorption capacity, pose a threat to plants by inhibiting seed germination, root elongation, and nutrient absorption. The accumulation of MPs induces oxidative stress, cytotoxicity, and genotoxicity in plants, which also impacts plant development, mineral nutrition, photosynthesis, toxic accumulation, and metabolite production in plant tissues. Furthermore, roots can absorb nanoplastics (NPs), which are then distributed to stems, leaves, and fruits. As MPs and NPs harm organisms and ecosystems, they raise concerns about physical damage and toxic effects on animals, and the potential impact on human health via food webs. Understanding the environmental fate and effects of MPs is essential, along with strategies to reduce their release and mitigate consequences. However, a full understanding of the effects of different plastics, whether traditional or biodegradable, on plant development is yet to be achieved. This review offers an up-to-date overview of the latest known effects of plastics on plants.

“…This indicates that aggregate‐size fractions respond differently to MPs exposure. MPs can reduce soil bulk density and soil micropores, which can hinder soil ventilation and thus prevent phosphorus release (Chia et al., 2022; de Souza Machado et al., 2019). With respect to available P, levels decreased with PA 1% and 3% (w/w), as well as with LDPE 3%.…”

Microplastics (MPs) are a significant threat to soils. However, there is scarce information on the impact of MPs on soil properties, particularly in volcanic ash‐derived soils. The objective of this study was to evaluate the impact of polyamide (PA) and low‐density polyethylene (LDPE) MPs on the biological and chemical characteristics of an Andisol from central Chile. Twenty‐one parameters were evaluated, including pH, electrical conductivity (EC), total organic carbon (TOC), dissolved organic carbon (DOC), total phosphorus (TP), available phosphorous (AP), available nitrogen (AN), inorganic nitrogen forms (NH4+, NO2− and NO3), carbohydrates (CHO), polyphenols (POLs), humic substances, soil basal respiration (SBR) and activities of soil enzymes such as dehydrogenase, β‐glucosidase, phosphatase and urease. For this, a microcosm was set up in clay pots in an incubation chamber at 21°C and 60% soil moisture, with the addition of PA and LDPE at doses of 1% and 3% w/w; a control treatment consisting of microcosm without MPs was also included. After 6 weeks of incubation, PA addition resulted in an increase in TOC and NH4+ by up to 32% and 26%, respectively, and a decrease in NO3− by 22%. AP decreased by 15%–19% with the addition of PA and LDPE. Similarly, acid phosphatase and β‐glucosidase activities decreased by 15% and 26% with PA and LDPE, respectively. The distance‐based linear model (DistLM) was used to analyse relationships in chemical and biological datasets. The analysis revealed that TOC and TP were primary components in the best model for predicting microbiological changes (R2 = .469, AICs = 16.026), indicating that MPs accumulation affects soil carbon cycling and P content. Overall, the results show that MPs addition alters soil chemical and microbiological properties in Andisols, with varying effects depending on the type and dose of MPs, with the highest dose (3%) producing the most marked negative effects.

“…This book is a timely publication and would be useful to researchers and teachers (professors) to learn and teach the emerging pollutants. It is expected that their occurrence, fate and transport characteristics would be very different from those of conventional and typical contaminants such as metals, organics, and nutrients (Chia et al, 2021(Chia et al, , 2022. However, it is not rarely known and studied much about the emerging ones (Lee et al, 2021(Lee et al, , 2022a.…”
