Research Focus

Dr. Bortey-Sam's work spans environmental toxicology, with emphasis on

• Heavy metal bioaccumulation (Pb, As, Cd)
• Air pollution effects on respiratory health
• PAH-induced oxidative stress and DNA damage
• Cyanide metabolism and poisoning diagnostics
• Epigenetic alterations from environmental exposures

Publication Trends

Recent work focuses on neonicotinoid exposure in Ghana (2021), cyanide toxicity in clinical settings (2021), and global DNA methylation changes from metal exposure (2019). Earlier studies examine pesticide residues in marine fish (2018), metal bioaccumulation in livestock (2018), and PAH-related respiratory impacts (2017).
