PPCPs include:

* Prescription and over-the counter therapeutic drugs * Veterinary drugs * Fragrances * Cosmetics * Sun-screen products * Diagnostic agents * Nutraceuticals (e.g., vitamins)

Sources of PPCPs:

* Human activity * Residues from pharmaceutical manufacturing (well defined and controlled) * Residues from hospitals * Illicit drugs * Veterinary drug use, especially antibiotics and steroids * Agribusiness
