High Quality Content by WIKIPEDIA articles! "Pharmaceuticals", or prescription and over-the-counter medications made for human use or veterinary or agribusiness purposes, are common PPCPs found in the environment. Antibiotics, nutraceuticals (e.g., vitamins), supplements, and sexual enhancement drugs are contained in this group. "Personal care products" may include cosmetics, fragrances, menstrual care products, lotions, shampoos, soaps, toothpastes, and sunscreen. These products typically enter the environment when passed through or washed off the body and into the ground or sewer lines, or when disposed of in the trash, septic tank, or sewage system. Illicit drugs such as methamphetamine and cocaine are another type of PPCP. The manufacturers of these products may accidentally spill or purposefully dump harmful byproducts directly into the environment.
