Passive semi-volatile atmosphere organic pollutant sampling apparatus

The invention discloses a passive semi-volatile atmospheric organic pollutant sampling device. The device comprises a top baffle plate, a hood, a support frame, a sampling tank and a bolt, wherein the top baffle plate is arranged on the top of the sampling device and used for sheltering from rain and preventing dust invading; the hood is used for eliminating the influence of wind speed on sample collection; the lower end of the support frame is connected with the inner wall of the hood, the upper end of the support frame is connected with the top baffle plate, and the support frame is used for connecting the top baffle plate and the hood position of the sampling device and positioning the sampling tank in the horizontal direction; the sampling tank is divided into two parts, and provided with an upper sealing opening and a lower sealing opening, the upper part is provided with a gaseous organic pollutant collecting medium, and the lower part is provided with a particle combining state organic pollutant collecting medium; and the bolt is used for positioning the sampling tank in the vertical direction. The device can match an active sampling device to obtain the sampling efficiency of the passive sampling device, reach the sampling amount of target compounds of the passive sampling device at day average unit, and estimate the concentration level of the gaseous and particle combining state semi-volatile organic pollutants.
