Changes of the human skin microbiota upon chronic exposure to polycyclic aromatic hydrocarbon pollutants
Abstract Background Polycyclic aromatic hydrocarbons (PAHs) are of environmental and public health concerns and contribute to adverse skin attributes such as premature skin aging and pigmentary disorder. However, little information is available on the potential roles of chronic urban PAH pollutant e...
