Teneur en nitrate dans l'eau souterraine

This indicator shows concentrations of nitrate (NO3) in groundwater bodies measured as milligrams per litre (mg NO3/L). The indicator can be used to illustrate geographical variations in current concentrations and temporal trends. Large inputs of nitrogen to water bodies from urban areas, industry, and agricultural areas, can have negative impacts on the use of water for human consumption and other purposes. The data stem from the EEA Waterbase database on the status and quality of Europe's rivers.

本指标用于表征地下水体中硝酸盐（NO3）的浓度，计量单位为毫克每升（mg NO3/L）。该指标可用于展示当前浓度的空间分布差异与时间变化趋势。城市、工业及农业区域向水体输入的大量氮素，会对饮用水及其他各类用水用途产生负面影响。本数据集来源于欧洲环境署（EEA）的Waterbase数据库，该数据库收录了欧洲河流的现状与水质相关信息。
