“…Chemicals commonly used for precipitation include lime [19], [20] as calcium hydroxide, sodium hydroxide, and sodium carbonate. Ion exchange is a process in which copper ions are exchanged with other ions on the surface of a solid resin material [21]. In comparison, adsorption attaches copper ions to the surface of adsorbent materials, such as activated carbon or zeolite [22].…”

Copper can be found in various equipment, building materials, and consumer products. When buildings are used, copper can enter wastewater in different ways. It is challenging for occupants to remove copper physically or chemically since they can potentially reduce copper levels through yard phytoarchitecture. This study aims to formulate houseplants' suitability to become decorative plants for the yard phytoarchitecture, simultaneously as onsite sanitation. This study identified the copper deconcentration pathway in wastewater by studying published works-based research. Literature was collected and selected based on recency, accessibility, and the relationship among copper, wastewater, and plants. The study findings show that processing copper by plant has the greatest opportunity to be implemented on a building scale. The yard phytoarchitecture system involves arranging plants in the yard, which serves both as a decorative feature and a way to treat the building's wastewater. It can be used on dry yards or ponds and only requires a small amount of land. The plants used should have low leaf density and high root density. It plays a dual role consisting of onsite sanitation infrastructure and yard aesthetics, which mutually strengthen the environmental health locally and positively effect on a larger scale.

“…As a result of the causes mentioned above and the adverse effects, different techniques for managing this type of waste have been sought, as well as new efficient and sustainable technologies to reverse and treat contaminated systems (38). In this sense, natural and man-made polymers are a viable route for reducing plastic pollution (39,40). Product of the causes mentioned above and the adverse effects is that different techniques of management of this type of waste have been sought, as well as new efficient and sustainable technologies to be able to reverse and treat contaminated systems.…”

Since 1950 plastics became the materials of greatest world production. Thus, in recent years the increase in the use of different types of plastics has been a matter of global concern due to the depletion of fossil fuels and the accumulation of waste in the different environmental matrices, affecting the ecosystem. By 2015, 4.9 million metric tons of plastic waste were recorded in landfills, because more than 40% of the plastics produced are designed for single use. The mass amount of plastic is estimated to exceed 450 million tonnes per year and will double by 2045.Due to the great problem of plastics and their threats to the ecosystem, the researchers worked on a large number of technologies to mitigate the effect of plastics on the different environmental matrices. Therefore, the main goal of this manuscript is summarizes on the plastics more used as well as the most common techniques to reduce their presence at the environment.

“…Thus, the incomplete process of microplastic degradation can result in the accumulation of these compounds at microbial and submicrobial scales, posing hitherto unknown dangers to the environment [76], in addition to the fact that in addition to animals in the terrestrial environment, the expansion and decomposition of plant matter can help the formation of macropores in the soil, being a transport agent for microplastic [82]. Among the most common contaminants in soils, we have organochlorine pesticides (OPs) [22,[83][84][85][86], polycyclic aromatic hydrocarbons (PHAs) [87][88][89] and heavy metals [90][91][92][93] that migrate vertically aided by the adsorption on the surfaces of microplastics in the soil through bioturbidification, runoff [94,95], water infiltration [96,97], irrigation channels [98], among others. While plastic particles can spread both through the air, allowing settlement anywhere (by atmospheric transport), including agricultural soils, sedimentation (see Figure 7) [99].…”

In recent decades the increase in the use of plastics has been exponential around the world, reaching a presence in places such as rivers, oceans and lakes, as well as in terrestrial environments such as agricultural soils. Associated with the great use of plastics in all areas of work, plastic particles smaller than 5 mm, called microplastics, have been found in all environmental matrices: aquatic environment, dispersed throughout the water column, terrestrial environment, infiltrating the soil sedimenting, and in the air, being transported by the wind. In each of these matrices, microplastic serves as transport for highly polluting compounds such as heavy metals, polycyclic aromatic hydrocarbons and organochlorine pesticides. In addition to environmental matrices, microplastics have been found in animals and humans in alarming numbers. In this way, this review addresses issues related to the formation and distribution of microplastics throughout the ecosystem and different organisms.
