Abstract：
Air pollution and the increasing production of greenhouse gases has prompted greater use of renewable energy sources; the EU has set a target that the use of green energy should be at 32 percent by 2030. With this in mind, in the last 10 years, the demand for pellets in Italy has more than doubled, making Italy the second largest consumer in Europe. The quality of the pellets burned in stoves is crucial to indoor and outdoor pollution. Among other parameters, moisture and ash are used to classify pellets according to EN ISO 17225:2014. This work involved the analysis of the organic and inorganic fraction of both some finished products on the Italian market and some raw materials (e.g., wood chips) sampled according to the technical standard EN 14778:2011. The analytical results showed the presence of some substances potentially harmful to human health such as formaldehyde, acetone, toluene and styrene for the organic fraction and nickel, lead and vanadium for the inorganic fraction. The chemometric approach showed that it is the inorganic fraction which is most responsible for the diversification of the samples under study. The detection of some substances may be a warning bell about the impact of such materials, both for the environment and for human health.
摘要：
空气污染和温室气体产量的增加促使人们更多地使用可再生能源；欧盟设定了一个目标，即到2030年，绿色能源的使用量应达到32％。考虑到这一点，在过去的十年里，意大利对颗粒的需求增加了一倍多，使意大利成为欧洲第二大消费国。在炉子中燃烧的颗粒的质量对室内和室外污染至关重要。在其他参数中，水分和灰分用于根据ENISO17225:2014对颗粒进行分类。这项工作涉及分析意大利市场上一些成品和一些原材料的有机和无机部分(例如，木片)根据技术标准EN14778:2011取样。分析结果表明存在一些对人体健康有潜在危害的物质，如甲醛，丙酮,甲苯和苯乙烯的有机部分和镍，铅和钒为无机部分。化学计量学方法表明，无机部分是研究样品多样化的最大原因。对某些物质的检测可能是对此类物质影响的警钟，对环境和人类健康都是如此。
