“…Zhejiang province in China showed soil microplastic concentrations below 150 μg/kg [24]. Caxias do Sul in Brazil exhibited microplastic concentrations of 21.30 μg/kg in its soil [25]. These findings illustrate the presence of microplastics in various environmental compartments, including sediment, soil, and sludge.…”

Bisphenol A (BPA) is recognized as an endocrine disruptor, capable of interfering with the normal functioning of hormones within the body by mimicking the effects of estrogen. Drinking water is one of the most common pathways of exposure to BPA as it can permeate plastic products and other materials, entering water sources. This article presents a comprehensive overview of BPA, including its incidence, origins, environmental fate, its impact on human health, and the role of fungi in the biodegradation of BPA. Fungi are natural decomposers, capable of breaking down organic compounds, including BPA, under suitable conditions. Studies have demonstrated that specific species of fungi can effectively biodegrade BPA. Some fungi utilize ligninolytic enzymes, such as laccases and peroxidases, to break down the phenolic rings of BPA. Other fungi employ non-ligninolytic enzymes, such as esterases and hydrolases, to cleave the ester linkages in BPA. Furthermore, some fungi can break down BPA via cometabolic pathways, whereby the chemical is degraded as a side reaction to the degradation of another substrate. The use of immobilized enzymes for BPA degradation has also demonstrated potential. Immobilized enzymes are those that are attached to a solid support, such as a polymer or matrix, allowing them to be used multiple times and enhance their stability and catalytic activity

Bisphenol A (BPA) is an anthropogenic chemical compound utilized to manufacture a wide range of consumer products, such as polycarbonate, polyvinyl chloride (PVC), food packages, and thermal papers. Because of its extensive worldwide use, BPA is pervasive in the environment, negatively affecting aquatic life. Therefore, we studied the occurrence, persistence, and ecological risk of BPA in surface water receiving raw leachate from a municipal solid waste (MSW) open dump in Kerawalapitiya, Sri Lanka. Our findings corroborate that the BPA average concentrations in the canal network were 0.4–42.6 µg/L during the wet season and 0.2–4.9 µg/L during the dry season. The levels of BPA at 11 locations (out of 16) during both seasons differed significantly from the upstream sample, where there was no impact from the dump site (p < 0.05), indicating the ubiquitous occurrence and persistence of BPA in the canal network. BPA levels in the waterbodies are greater in the wet period than in the dry period because of the continuous ingress of run‐off‐driven leachate to the canal network. Our study infers that pH and salinity correlate positively with BPA, while temperature, DO, and TSS are negatively correlated with BPA. BPA levels in five locations during the wet season and one during the dry season surpassed the tolerable level of BPA stipulated by the Canadian Federal Environmental Quality Guidelines to safeguard aquatic life, which is 3.5 µg/L. The findings of the acute ecological risk assessment articulate that during the wet season, Mozambique tilapia (Oreochromis mossambicus) and orange chromide (Etroplus maculatus) constitute a high acute risk, while they pose a medium acute risk during the dry season. Our study suggests that the relevant authorities must prevent the ingress of runoff rich with BPA onto the canal network to protect aquatic life.

Landfilling is the preferred method of solid waste disposal globally, but landfills are sources of several pollutants including heavy metals, phthalates, phenols, and other chemicals to the environment. Phthalates and phenols are widely used in the manufacture of everyday household products and are therefore contained in leachate generated in landfills where these products are disposed. These pollutants have endocrine disruptive capabilities and are considered as priority pollutants. Knowledge of their fate in the environment is of relevance to their management and the reduction of associated human and animal exposure risk. Several studies have profiled these pollutants in wastewater, but little information is available on their presence and fate in landfill environments and surrounding soils. Further to this, their degradation pathways have mostly been reported in laboratory simulated studies where the media may not be as complex and dynamic as landfills and surrounding soil environments. The factors and processes affecting their release from waste materials in landfills and their dispersal into surrounding environments has also not been reported, yet this knowledge is relevant for the design of any remediation measures. This article reviews the sources, occurrence, and degradation of phenols and phthalates in landfilled wastes and landfill leachate, and the factors influencing their fate in the landfill and surrounding soils contaminated with landfill leachates. We conclude with a discussion on the exposure pathways and exposure routes of these compounds from landfills to humans and the associated health risk and possible future research opportunities.
