Beschreibungen/Notizen

• PCDD/F concentration in deposition and in ambient air was measured at different locations in the state of Baden-Württemberg, Germany. The average dioxin concentration in particulate deposition ranged from 5 to 36 pg I-TEQ/m 2d, while the ambient air concentration ranged from 14 to 77 fg I-TEQ/m 3. In addition, particulate depositions (mg/m 2d), calculated PCDD/F concentration in particulate depositions (ng I-TEQ/kg), suspended particles (< 10 μm) in air (μg/m 3) and the calculated PCDD/F concentration in suspended particulate matter (ng I-TEQ/kg) are reported. Rural areas and urban areas differ in PCDD/F pollution. Connections of PCDD/F concentration vs. temperature, PCDD/F concentration in grass vs. deposition and PCDD/F concentration in deposition vs. rainfall have been measured. The rural area in elevated exposition (Black Forest) reflects the influence of weather and long range transport.
