Research Summary

(inferred from publications by AI)

The researcher has conducted extensive research across multiple domains, focusing on environmental health issues, particularly the impact of pesticides, pharmaceuticals, and pollutants on human health and ecosystems. Their work encompasses a wide range of topics, including heavy metal contamination in Ghana’s environment, antibiotic residues in water and land ecologies, toxicity studies involving hazardous chemicals such as铅, arsenic, cadmium, and mercury, and the integration of analytical techniques to assess trace elements’ bioactivities. The research also explores the physiological and psychological effects of neurotoxins and evaluates the pharmacokinetics of substances like vetropresvernas in animals. Additionally, their studies cover innovative methods for recycling materials with promising applications in agriculture, pharmaceuticals, and waste management.
