Risk of heavy metals from application of sewage sludge

Data on Overall Contamination Rate Indices at NUTS2 level based on National or EU limit values and dependent/independent on pH values. Maximum amount of sewage sludge (Mg ha-1 ) that can be applied at NUTS2 level taking into consideration the EU limit values for concentration of heavy metals. Distribution of potential ecological risk index (RI) before and after the application of sewage sludge over 10 consecutive years at 5 Mg ha-1 rate.
