Abstract

The indiscriminate use of pesticides in Malaysian agriculture poses serious risks to both human health and groundwater quality.This study aims to evaluate the extent of pesticide contamination in Malaysian groundwater, identify its major sources, and examine current mitigation efforts. The primary routes of contamination include direct application, soil leaching, and surface runoff, with over twenty pesticide compounds listed as priority hazardous substances, commonly linked to oil palm, rice, and vegetable farming. Residential and industrial activities also contribute to the pollutant load. Due to their long environmental persistence, pesticides threaten aquatic ecosystems through bioaccumulation and biomagnification and increase the risk of severe health issues, including neurological disorders, reproductive problems, and cancer. Regulatory controls such as exposure limits and monitoring programs have been implemented to manage these risks. This review concludes that while regulatory mechanisms exist, more robust and proactive approaches are needed to mitigate groundwater contamination. Future efforts should focus on expanding the adoption of sustainable farming practices, strengthening groundwater monitoring, and enhancing regulatory enforcement to ensure long-term environmental and public health protection.

Abstract

Sustainable construction is essential for minimizing greenhouse gas emissions, reducing waste, and promoting cost efficiency. However, Malaysia faces persistent challenges in environmental management, development approval procedures, and the adoption of green technologies. While various studies have explored individual aspects of sustainability in construction, there remains a lack of comprehensive reviews that critically assess how regulatory frameworks, approval processes, and green technologies intersect to influence sustainable construction outcomes in the Malaysian context. This review addresses that gap by synthesizing current practices, identifying key bottlenecks, and proposing actionable strategies for improvement. It evaluates regulatory frameworks, environmental strategies, green materials, and advanced technologies that support sustainable construction. The efficiency of the development approval process including project proposals, land acquisition, planning approval, occupancy, and handover plays a crucial role in enabling sustainable outcomes. Green technologies such as renewable energy, solar power, and smart construction techniques like the Internet of Things (IoT) are examined for their potential to enhance sustainability. The review also highlights persistent gaps in cost management and regulatory enforcement. By consolidating diverse strands of knowledge, this paper contributes to a clearer understanding of systemic barriers and opportunities within Malaysia’s sustainable construction landscape, offering policy and practice recommendations to guide future progress.

Abstract

The objective of this study is to develop effective chemical treatment methods to break down stubborn pharmaceutical pollutants in contaminated soil, enhancing its quality and reducing environmental risks. Numerous pharmaceuticals, which are substances used to cure or prevent illnesses in both humans and animals, are classified as pollutants of increasing concern because of their extensive environmental dispersion and their negative effects on populations. This is due to the constant discharge of sludge and effluent from wastewater treatment plants, which happens far more quickly than the removal of pharmaceuticals; they are frequently discovered in soils at considerable concentrations. Conventional wastewater treatment is unable to effectively remove pharmaceuticals from influent streams or biosolids, despite the fact that they are often present at low ambient quantities. Furthermore, through surface runoff and leaching, the application of animal manure to the soil can cause pharmaceuticals to contaminate the soil. Adsorption to soil colloids and degradation through the soil profile are some of the mechanisms that influence the behaviour and fate of pharmaceuticals in soils. The primary factor influencing how much organic matter is absorbed by plant roots is the sorption of pharmaceuticals in soils. This pharmaceutical pollutant in contaminated soil can lead to a negative impact on human and soil health. Therefore, remediation techniques such as chemical oxidation, soil washing, bioremediation, and phytoremediation should be used to reduce the pharmaceutical pollutants in the contaminated soil.
