Abstract

Observations of particulate matter less than 10 µm (PM₁₀) were conducted from January to December in 2015 in the Ciuc basin, Eastern Carpathians, Romania. Daily concentrations of PM₁₀ ranged from 10.90 to 167.70 µg/m³, with an annual mean concentration of 46.31 µg/m³, which is higher than the European Union limit of 40 µg/m³. Samples were analyzed for a total of 21 elements. O, C and Si were the most abundant elements accounting for about 85% of the PM₁₀ mass. Source identification showed that the elemental composition of PM₁₀ is represented by post volcanic activity, crustal origin, and anthropogenic sources, caused by the resuspension of crustal material, sea salt and soil dust. The average PM₁₀ composition was 72.10% soil, 20.92% smoke K, 13.84% salt, 1.53% sulfate and 1.02% organic matter. The back-trajectory analysis showed that the majority of PM₁₀ pollution comes from the West, Southwest and South.

罗马尼亚东喀尔巴阡山脉PM10来源识别和暴露评估

2015年1 - 12月在罗马尼亚东喀尔巴阡山脉的Ciuc盆地进行了10µm以下颗粒物(PM10)的观测。PM10日浓度范围为10.90 ~ 167.70µg/m3，年平均浓度为46.31µg/m3，高于欧盟规定的40µg/m3。样品共分析了21种元素。O、C和Si是最丰富的元素，约占PM10质量的85%。来源鉴定表明，PM10元素组成有火山后活动、地壳成因和地壳物质再悬浮、海盐和土壤尘埃等人为来源。PM10平均组成为土壤72.10%、烟K 20.92%、盐13.84%、硫酸盐1.53%、有机质1.02%。反轨迹分析显示，PM10污染主要来自西部、西南部和南部。

期刊介绍： The Journal of Atmospheric Chemistry is devoted to the study of the chemistry of the Earth''s atmosphere, the emphasis being laid on the region below about 100 km. The strongly interdisciplinary nature of atmospheric chemistry means that it embraces a great variety of sciences, but the journal concentrates on the following topics: Observational, interpretative and modelling studies of the composition of air and precipitation and the physiochemical processes in the Earth''s atmosphere, excluding air pollution problems of local importance only. The role of the atmosphere in biogeochemical cycles; the chemical interaction of the oceans, land surface and biosphere with the atmosphere. Laboratory studies of the mechanics in homogeneous and heterogeneous transformation processes in the atmosphere. Descriptions of major advances in instrumentation developed for the measurement of atmospheric composition and chemical properties.
