WFD Cycle 2 Lake Ammonia Classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Ammonia in lakes. Ammonia is a decay product of nitrogenous organic wastes and of the breakdown of animal and vegetable wastes. Sewage effluent is a major source, as are agricultural diffuse sources associated with fertiliser application. Ammonia is used in many cleaning products and in fermentation processes.

Ammonia data is run through a database that calculates summary statistics (Mean, standard deviation) at each site based on the number of samples taken in the classification period. These statistics are then entered into a calculator tool to generate classifications. Ammonia standards are used for Ammonia classification and they set up the boundaries between the various status levels e.g. High, Good, Moderate etc. The standards are ‘Waterbody’ specific based on the Typology of the lake, the altitude and alkalinity.

本数据集为“WFD 分类状态循环 2”的子集，包含湖泊中氨的分类数据。氨为含氮有机废物分解以及动植物废物降解的产物。污水中是氨的主要来源，与肥料施用相关的农业扩散源亦是重要来源。氨在众多清洁产品和发酵过程中得到广泛应用。氨数据经过数据库处理，基于分类期间采集的样本数量，在每个监测点计算汇总统计量（平均值、标准差）。随后，这些统计量被输入至计算工具，以生成分类结果。氨标准用于氨的分类，并设定了不同状态级别（如高、良好、中等等）之间的界限。标准依据湖泊的类型、海拔和碱性等因素，针对不同的水域体进行定制。归属声明：© 环境署版权及/或数据库权利2016。版权所有。
