摘      要：Phthalate esters(PAEs),typical pollutants widely used as plasticizers,are ubiquitous in various indoor and outdoor *** exist in both gas and particle phases,posing risks to human *** the present study,we chose four typical kinds of indoor and outdoor environments with the longest average human residence times to assess the human exposure in Hangzhou,including newly decorated residences,ordinary residences,offices and outdoor *** order to analyze the pollution levels and characteristics of 15 gasand particle-phase PAEs in indoor and outdoor environments,air and particulate samples were collected *** total PAEs concentrations in the four types of environments were 25,396,25,466.8,15,388.8 and 3616.2 ng/m^3,*** and DEP were the most abundant,and DMPP was at the lowest *** variations in the distributions of indoor/outdoor,gas/particle-phase and different molecular weights of PAEs were observed,showing that indoor environments were the main sources of PAEs *** most PAEs tended to exsit in indoor sites and gas-phase,the high-molecular-weight chemicals tended to exist in the particle-phase and were mainly found in *** were more likely adsorbed by small particles,especially for the indoor *** existed a good correlation between the particle matter concentrations and the PAEs *** addition,neither temperature nor humidity had obvious effects on the distributions of the PAEs concentrations.
