Abstract

Chlorpyrifos (CP) is a widely used organophosphate pesticide known for its recalcitrant nature, raising concerns about potential ecological and health impacts due to its toxicity. Many plants and animals are contaminated with this pesticide. Microbial biodegradation offers an environmentally friendly and effective method to remove CP from the environment and mitigate its impacts, especially given its low cost, particularly when bioremediation is conducted on-site. Different types of microbial species have been found to function under various environmental conditions, with some, like Pseudomonas nitroreducens PS-2 and Pseudomonas aeruginosa (NCIM 2074), showing promising results with degradation rates of up to 100%. However, challenges exist, such as partial degradation caused by the presence of metabolites, and the recalcitrant nature of CP, which can impede microbes' ability to effectively degrade its hydrocarbon ring. Overall, a combination of approaches, such as microbial and algal methods, or the discovery of new microbial strains, can help overcome these challenges and further enhance the long-term viability of this technique.

Abstract

Pharmaceuticals in Malaysia’s groundwater are a growing concern as they can potentially affect the environment and human health negatively. Pharmaceuticals are found in abundance in groundwater from sources such as septic tanks, leachates from landfills, wastewater effluents from pharmaceutical-related industries, medical institutions, wastewater treatment plants, and households, agriculture runoff and leakage of effluent wastes in Malaysia. Pharmaceutical contaminant usually travels through advection and dispersion from waterways or soil into the groundwater. The mathematical model of the advection-dispersion equation and enzyme-linked immunosorbent assay (ELISA) are analysed for the prediction of movement and concentration of pharmaceuticals.  Furthermore, the evolution of pharmaceuticals in the environment, living organisms and human health is assessed. Pharmaceuticals have found their way into the food chain and exhibit toxicity and hazard to aquatic ecosystems. However, the toxicity of pharmaceuticals to humans is still not yet much to be researched although strong evidence of possible negative consequences. Moreover, remediation technologies such as activated carbon adsorption, activated sludge, anaerobic treatment and advanced oxidation process are discussed for the mitigation of pharmaceuticals contamination.

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.

Abstract

This review provides an overview of Malaysia's environmental management practices, with a focus on construction waste management, to address the country's growing waste generation in the construction sector. The paper highlights key challenges Malaysia faces in implementing effective environmental practices and offers potential solutions to overcome these hurdles. Additionally, it examines the use of green materials, such as recycled concrete aggregate and bamboo, which have demonstrated significant potential in reducing resource consumption and carbon emissions. The challenges of adopting these materials are analyzed, along with a discussion of their advantages and limitations. Ultimately, the review underscores the importance of environmental management and the role of sustainable materials in transforming Malaysia’s construction industry, while calling for stronger regulatory frameworks and industry collaboration to address these challenges. The objective of this review is to provide insights into the current environmental management efforts in Malaysia and to explore the potential of green materials in mitigating environmental impacts.

Abstract

The widespread use of pesticides in agriculture, aquaculture, and public health has led to severe environmental and public health concerns due to their overapplication and persistence in ecosystems. Pesticide residues accumulate in soil, degrade its fertility, pollute groundwater, and harm non-target organisms, including beneficial insects and aquatic life. This persistent contamination poses a significant threat to biodiversity, food safety, and ecosystem resilience. The aim of this review is to examine microbial bioremediation as a sustainable and effective strategy for remediating pesticide-contaminated soils. The paper evaluates the mechanisms by which microorganisms degrade or transform hazardous pesticide compounds into less toxic or non-toxic forms and assesses the advantages and limitations of bioremediation technologies. Notably, bioremediation is recognized for its environmental compatibility, cost-effectiveness, and potential to restore soil health without undermining agricultural productivity. Recent studies highlight promising microbial strains capable of degrading diverse classes of pesticides under varying environmental conditions. However, challenges remain, including the scalability of microbial technologies, the complexity of mixed-contaminant sites, and the influence of abiotic factors on microbial efficacy. Future research should focus on optimizing microbial consortia, integrating genetic and metabolic engineering approaches, and developing field-scale applications tailored to specific agroecosystems. Advancing these areas will be critical for establishing bioremediation as a central pillar in sustainable pesticide management and environmental restoration strategies.
