大气颗粒物污染是整个欧盟的一个重大问题，人们担心，由于燃料价格上涨和对使用可再生能源的兴趣增加，生物质燃烧的贡献可能越来越大。这项研究的目的是评估目前生物质燃烧的水平和对西北欧五个地点总PM10的贡献;该地区经常受到空气质量差的影响。通过测定2013/2014年14个月期间收集的PM10气溶胶过滤器中的左旋葡聚糖浓度，对生物质燃烧进行定量，并在英国莱斯特的研究中心继续进行12个月。左旋葡聚糖水平表明11月至3月之间的生物质燃烧增加的一个明显时期。在此期间，月平均浓度介于23 +/- 9.7和283 +/- 163纳克/立方米之间，里尔的浓度始终高于比利时、荷兰和联合王国的监测点。正如预期的那样，对PM10的估计贡献在冬季最高，其中Wijk aan Zee的季节平均百分比贡献最低，为2.7 +/- 1.4%，里尔的季节平均百分比贡献最高，为11.6 +/-3.8%，来自生物质的PM10质量浓度范围从莱斯特的0.56 μ g/m（3）到里尔的2.08 μ g/m（3）。总的来说，在不同地点测量的左旋葡聚糖浓度之间的相关性很差，这表明通常生物质燃烧只会影响当地的大气颗粒物污染;然而，有证据表明，传统上在西北欧部分地区举行的复活节大火等极端燃烧事件可能对空气质量产生更广泛的影响。网络验证测量也采取了使用移动的监测站访问的固定站点进行并行收集的气溶胶过滤器，其结果表明，PM10和左旋葡聚糖测量的可靠性。(C)2016爱思唯尔有限公司版权所有。
Atmospheric particulate pollution is a significant problem across the EU and there is concern that there may be an increasing contribution from biomass burning, driven by rising fuel prices and an increased interest in the use of renewable energy sources. This study was carried out to assess current levels of biomass burning and the contribution to total PM10 across five sites in North-West Europe; an area which is frequently affected by poor air quality. Biomass burning was quantified by the determination of levoglucosan concentrations from PM10 aerosol filters collected over a 14 month period in 2013/2014 and continued for a further 12 months at the UK site in Leicester. Levoglucosan levels indicated a distinct period of increased biomass combustion between November and March. Within this period monthly average concentrations ranged between 23 +/- 9.7 and 283 +/- 163 ng/m(3), with Lille showing consistently higher levels than the sites in Belgium, the Netherlands and the UK. The estimated contribution to PM10 was, as expected, highest in the winter season where the season average percentage contribution was lowest in Wijk aan Zee at 2.7 +/- 1.4% and again highest in Lille at 11.6 +/- 3.8%, with a PM10 mass concentration from biomass that ranged from 0.56 mu g/m(3) in Leicester to 2.08 mu g/m(3) in Lille. Overall there was poor correlation between the levoglucosan concentrations measured at the different sites indicating that normally biomass burning would only affect atmospheric particulate pollution in the local area; however, there was evidence that extreme burning events such as the Easter fires traditionally held in parts of North-West Europe can have far wider ranging effects on air quality. Network validation measurements were also taken using a mobile monitoring station which visited the fixed sites to carry out concurrent collections of aerosol filters; the result of which demonstrated the reliability of both PM10 and levoglucosan measurements.
