This proceeding focuses on the intersection of toxicology, waste management, and public health. Structured into three thematic sections, it addresses critical challenges posed by hazardous materials during crises. It delves into environmental toxicological mechanisms, exploring how pollutants such as medical waste, PFAS, and antibiotic waste migrate through ecosystems, undergo chemical transformations, and trigger synergistic toxicity. It emphasizes predictive modeling for emerging contaminants like nanomaterials and viral vectors. It evaluates pollution control technologies, comparing risks of incineration, chemical disinfection, and biodegradable alternatives (e.g., bio-based PPE). Advanced solutions like AI-driven monitoring systems and microbial remediation for contaminated sites are highlighted. Combining scientific rigor with policy analysis, this book advocates for integrated approaches to mitigate ecological and public health risks in future emergencies.
