Investigating Chemical Pollution from Agricultural Drainage in the Djoudj National Bird Park (Senegal)

Alarming levels of chemical contamination, including banned pesticides and high concentrations of lead, have been detected in the Djoudj National Bird Park, a critical Ramsar-listed wetland in Senegal. The study found peak lead levels exceeding 7,000 µg/kg and persistent organic pollutants like lindane and dicofol at up to 200,000 µg/kg, linked to agricultural drainage from surrounding rice fields. Seasonal variability, particularly during the dry season, exacerbates pollution pulses, with hydrological conditions influencing pollutant mobility and bioavailability. The findings highlight severe ecological risks for migratory birds and aquatic biodiversity, necessitating urgent mitigation strategies such as buffer zones, integrated pest management, and stricter regulatory enforcement to safeguard this protected wetland.
