IREA — 06. Use OF SOLVENTS — Indicator

The service presents data in the form of an indicator for emissions related to the macro-sector “Use of solvents” of the Regional Inventory of Atmospheric Emissions (IREA).Estimates made are calculated on the basis of the INEMAR (air emission inventory) system based on the EMEP — CORINAIR methodology and relate to sources classified according to the SNAP (Selected Nomenclature for Air Pollution) nomenclature. They are classified according to the following parameters: reference year, province and municipality, reference activities according to the SNAP methodology (macrosector, sector and emissive activity), fuel used and pollutant emitted. The main pollutants exposed are: CH4 (tonnes/year); Co (t/year); CO2 (kt/year); N2O (t/year); NH3 (t/year); NMVOC (t/year); NOx (tonnes/year); PM10 (tonnes/year); PM2.5 (tonnes/year); PTS (t/year); SO2 (tonnes/year). The data shall be rounded to the fourth decimal place. The service exposes the data in four different spatial resolutions: Municipalities, Provinces, Region, Air Quality Zones.By a special function in the Environmental Knowledge System it is possible to view the themed inventory data according to three different types of statistical classification (Jenks, Equal Interval, Quantile).The WFS service can also be used in any GIS desktop (e.g. QGIS).本服务以指标形式提供区域大气排放清单（Regional Inventory of Atmospheric Emissions, IREA）中"溶剂使用"宏观门类相关的排放数据。本次估算基于INEMAR（空气排放清单系统）开展，采用EMEP-CORINAIR方法学，数据源按照大气污染选定命名法（Selected Nomenclature for Air Pollution, SNAP）进行分类。数据依据以下参数完成分类：基准年、省、市镇、基于SNAP方法学的基准活动（含宏观门类、子门类及排放活动）、使用的燃料以及排放的污染物。公开的主要污染物包括：甲烷（CH4，吨/年）、钴（Co，吨/年）、二氧化碳（CO2，千吨/年）、一氧化二氮（N2O，吨/年）、氨（NH3，吨/年）、非甲烷挥发性有机化合物（NMVOC，吨/年）、氮氧化物（NOx，吨/年）、PM10（吨/年）、PM2.5（吨/年）、持久性有毒物质（PTS，吨/年）以及二氧化硫（SO2，吨/年）。所有数据将四舍五入至小数点后四位。本服务提供四种空间分辨率的数据：市级、省级、区域级以及空气质量功能区级别。通过环境知识系统中的专属功能，可依据三种统计分类方法（詹克斯自然间断点法、等间距分级法、分位数分级法）查看主题式清单数据。网络要素服务（Web Feature Service, WFS）还可在任意地理信息系统（Geographic Information System, GIS）桌面端（如QGIS）中使用。
