Nitrate Vulnerable Zones (NVZ) 2017 - Combined (Final Designations)

PLEASE NOTE: This dataset has been retired, as it has been superseded by the dataset for Nitrate Vulnerable Zones (NVZ) 2021 Designations. See: https://environment.data.gov.uk/dataset/60be356d-6475-4d51-9572-9f8c09f1a764

This dataset sets out the Nitrate Vulnerable Zone designations following the 4 yearly review for implementation in 2017. These are the final designations following appeals.

Nitrate Vulnerable Zones (NVZs) are areas designated as being at risk from agricultural nitrate pollution.
The designations are made in accordance with the Nitrate Pollution Prevention Regulations 2015.

Waters are defined within the Nitrates Directive as polluted if they contain or could contain, if preventative action is not taken, nitrate concentrations greater than 50mg/l.

请注意：本数据集已淘汰，因其已被2021年硝酸盐易受影响区域（NVZ）指定数据集所取代。详见：https://environment.data.gov.uk/dataset/60be356d-6475-4d51-9572-9f8c09f1a764
本数据集旨在阐述硝酸盐易受影响区域（NVZs）的指定，该指定基于每四年一次的审查，以在2017年实施。这些是经过上诉后的最终指定。
硝酸盐易受影响区域（NVZs）是指那些面临农业硝酸盐污染风险的区域。这些指定是根据2015年硝酸盐污染预防法规进行的。
根据硝酸盐指令，若水体中硝酸盐浓度超过50mg/l，或如不采取预防措施，可能超过此浓度，则该水体被视为受污染。
本数据集取代了之前的“硝酸盐易受影响区域（NVZ）2017 – 表面水体/地下水/富营养水体（上诉前）”数据集。归属声明：© 环境局版权和/或数据库权利。
