Abstract

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

Abstract

Endocrine-disrupting compounds (EDCs) have garnered increasing concern in recent years due to their association with severe health issues and significant environmental impacts. EDCs, which can interfere with endogenous hormone systems, are diverse in structure and are often characterized by low molecular mass and halogen substitutions. Their presence in the environment, originating from both natural and synthetic sources, has been well-documented in water bodies, but studies on their occurrence in soils remain limited. This review provides a comprehensive overview of the occurrence, contamination, and impacts of EDCs in the urban soils of Malaysia. The paper discusses the primary sources of EDCs, including pharmaceuticals, pesticides, industrial chemicals, and combustion byproducts, and examines the pathways through which these compounds enter the soil. Health risks associated with exposure to EDCs, as well as their ecological consequences, are also explored. The review highlights the current status of EDCs contamination in Malaysian soils, identifies gaps in research, and outlines the challenges in monitoring and mitigating these contaminants. Understanding the dynamics of EDCs in soil is crucial for developing effective strategies to protect human health and the environment in urban settings.
