Abstract

Biochar gained significant attention as an eco-friendly and effective solution for remediating contaminated soils, particularly those impacted by pharmaceutical persistent pollutants (PPPs). These pollutants, known for their resistance to natural degradation and tendency to accumulate in soil, posed serious risks to both human health and ecosystems. To address this issue, researchers proposed the use of biochar as a remediation technology to remove PPPs through adsorption. As an efficient sorbent, biochar demonstrated the ability to immobilize pharmaceuticals in contaminated soils, thereby reducing their bioavailability and mobility, and ultimately mitigating their environmental impact. This review aimed to provide a comprehensive overview of the current understanding of PPPs contamination and the potential of biochar for remediation. It first summarized the occurrence of pharmaceutical pollutants in various countries and identified their primary sources. It then examined the environmental fate of these pollutants and outlined the key challenges associated with their management. The mechanisms by which biochar adsorbed pharmaceutical compounds were discussed in detail, followed by a case study that illustrated the effectiveness of this technology in practical applications. This review also evaluated the advantages and disadvantages of using biochar for remediation, along with the practical challenges encountered during its implementation. Future directions highlighted included developing methods for extracting toxic residues and enhancing the performance of biochar through chemical or structural modifications.

Abstract

Malaysia’s rapid urbanization, driven by a growing population and increasing industrial and infrastructural demands, significantly impacted the environment. The construction sector, a key contributor to economic growth, simultaneously became a major source of environmental degradation due to high resource consumption and waste generation. In response to these challenges, the integration of green materials and sustainable technologies emerged as a viable solution to minimize the negative environmental footprint of construction activities. This paper provides a comprehensive overview of the current state of green materials in Malaysia, including bamboo, organic waste, recycled concrete aggregate, and plastic waste, highlighting their benefits and limitations. Additionally, sustainable construction technologies such as solar energy, hydropower, biogas systems, green roofing, and rainwater harvesting are examined for their potential role in enhancing environmental sustainability. The study further evaluates existing government policies and regulations governing green construction in Malaysia, identifying key challenges such as ineffective waste management, regulatory enforcement gaps, and illegal dumping. Comparisons with international best practices, including those from Japan and Hong Kong, offer insights into potential improvements for Malaysia’s regulatory framework and implementation strategies. The paper also discusses the prospects of green materials and sustainable construction technologies, outlining potential solutions to enhance their adoption. By addressing both the challenges and opportunities within the sector, this review aims to contribute to the advancement of sustainable construction practices in Malaysia, ultimately fostering a eco-friendlier and more resilient built environment.

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.
