Abstract: With the large scale development of pharmaceutical and cosmetic industries, the production and use amount of pharmaceuticals and personal care products (PPCPs) are remarkably increased, resulting in the PPCPs remaining in water, soil, and air environment. Regrettably, as a large class of environmental pollutants, PPCPs have not drawn adequate attention till the late 1990s. Due to the continuous input to the environment in high quantity, the residual concentration of PPCPs is increasing, and gradually shows ecological toxicity to the microorganisms, plants and animals, and even, potential ecological risk to human beings. Based on the sum-up of published literatures, this paper analyzed the pollution sources and environmental remaining of PPCPs, as well as the ecological toxicity of residual PPCPs to the microorganisms, plants, animals, and human beings. The main scientific issues related to PPCPs, which should be researched in the future, were suggested.
