Abstract: In the study, we examined the complex, interconnected and interdependent nature of social, economic, health and environmental dimensions of the Sustainable Development Goals (SDGs) and offer pathways for policy intervention to address the impacts of heavy metal pollutants in the environment. Potentially toxic metals (PTMs) (also called heavy metal) contamination in groundwater poses a significant threat to public health and environmental sustainability, particularly in urban areas like Alaba International Market and Olusosun communities in Lagos State, Nigeria. This issue highlights the paradoxical nature of sustainable development, where economic activities such as e-waste processing can compromise environmental and social pillars. The Equilibrium Perspectives Paradox Framework suggests that achieving sustainable development requires balancing these interconnected pillars. To address this challenge, a strategic action plan has been proposed: 1.) Establishment of a Stakeholder Committee: Comprising government representatives, scientific organizations, community associations, and NGOs to implement effective management strategies. 2.) Regulatory Enforcement: Strict regulations for e-waste handling and disposal. 3.) Groundwater Monitoring: Continuous quality checks to ensure public health safety. 4.) Health Risk Assessments: Regular evaluations focusing on vulnerable populations like children. 5.) Public Awareness Campaigns: Educating the public about health risks associated with PTMs contamination. Implementing these measures will help mitigate the negative impacts of heavy metal pollutants on groundwater while aligning with Sustainable Development Goals (SDGs) related to health (SDG 3), water quality (SDG 6), and environmental protection (SDGs 11, 12, 14 and 15). This approach underscores the need for integrated policies that balance economic growth with social equity and environmental sustainability.

Abstract: Ants, common in urban ecosystems, often infiltrate hospital environments, where they can interfere with infection control measures. This study examined their ecological role in 15 hospitals across Nigeria, focusing on high-risk areas such as kitchens, waste disposal zones, and patient wards. Over 500 ant specimens were aseptically collected and analyzed using molecular and microbiological techniques, revealing contamination with pathogenic microorganisms like Listeria monocytogenes and Staphylococcus aureus. Ants were identified using morphological keys, and bacteria were isolated from the specimens using selective agars. The presence of antimicrobial-resistant bacteria carried by ants highlights the need for heightened awareness and stricter infection control measures in healthcare settings. While ants may act as mechanical vectors, facilitating the transmission of infectious agents, within healthcare settings, particularly in areas with suboptimal sanitation and inadequate pest control this study emphasizes the importance of addressing this issue in infection control protocols. This study recommends integrated pest management, routine sanitation, and structural modifications to reduce ant infestations. It also suggests adopting DNA-based microbial monitoring for early detection of contaminants. Hospitals should prioritize simple yet effective measures, such as proper hand hygiene, judicious use of antimicrobials, and robust pest control programs. By addressing ant-mediated pathogen spread, this research offers valuable insights to improve infection control strategies and enhance patient safety in modern healthcare environments.
