Article Title: Household Waste Disposal of Pharmaceuticals and Personal Care Products (PPCPs) as a Pathway for Environmental Contamination: A case Study at University of Port Harcourt, Port Harcourt, Nigeria:
This study evaluated the relative amount of Pharmaceutical and Personal Care Products (PPCPs) contained in household waste at the University of Port Harcourt, Port Harcourt, Nigeria. Solid waste analysis recorded 0.9 kg/capita/day and 1.1 kg/capita/day for the student hostel and staff quarters respectively. The student’s hostel recorded a mean percentage PPCPs value of 52.9% which was higher than that obtained in the staff quarters (45.9%) indicating that students disposed of more drugs in their waste than does the staff. The study showed that considerable amounts of PPCPs are disposed of in household waste at the study location and household waste is thus a viable pathway of PPCPs into the environment. Such practices could lead to the occurrence of the active ingredients of PPCPs in the environment with the potential to contaminate surface and ground water posing serious risk to human and ecologic health. It was recommended that appropriate return channels be established specially as a route for disposing of unused or expired drugs. Such routes should encourage stewardship of drugs by manufacturers from cradle to grave in an integrated green pharmacy approach.
