Samples were collected between May 2003 and May 2004 in Izmir, Turkey to measure dry and wet deposition of formaldehyde (HCHO). Particle-phase HCHO fluxes measured with dry deposition plates ranged between 2 and 56 microg m(-2) day(-1) (average+/-SD, 17+/-12 microg m(-2) day(-1)). Particulate phase dry deposition velocities calculated using the particulate fluxes measured and ambient particulate concentrations ranged from 0.1 to 9.6 cm s(-1) (1.4+/-1.4 cm s(-1)). The particulate overall dry deposition velocity agreed well with those measured previously for other pollutants using the same method. Formaldehyde concentration measured in 27 rain samples collected at the sampling site ranged between 10 and 304 microg l(-1). The annual formaldehyde wet deposition was calculated as 31.4 mg m(-2) year(-1). The annual HCHO total deposition (wet+dry) was dominated by wet deposition (83.7%).
2003年5月至2004年5月期间,在土耳其伊兹密尔采集样本,以测量甲醛(HCHO)的干湿沉降。用干沉降板测量的颗粒相HCHO通量在2至56微克/平方米·天之间(平均值±标准差,17±12微克/平方米·天)。根据测量的颗粒通量和环境颗粒浓度计算出的颗粒相干沉降速度在0.1至9.6厘米/秒之间(1.4±1.4厘米/秒)。颗粒相的总体干沉降速度与之前使用相同方法测量的其他污染物的干沉降速度吻合良好。在采样点采集的27个雨水样本中测得的甲醛浓度在10至304微克/升之间。甲醛的年湿沉降量计算为31.4毫克/平方米·年。HCHO的年总沉降量(湿沉降+干沉降)以湿沉降为主(83.7%)。
