Comment(s)

• With the reporting year 2010 a new compulsory nationwide report format for the reporting of the responsible supreme Land authorities was introduced (reporting years 2010 to 2013: Federal Health Bulletin ("Bundesgesundheitsblatt") 2008·51:1.078-1.092, reporting years 2014 to 2016: Federal Health Bulletin ("Bundesgesundheitsblatt") 2013·56:1.191-1.215).
• In the reporting year 2010, no data are included for Baden-Wurttemberg and Saarland.
• ¹⁾ For the number of monitored water supply areas a value for the sum of individual pesticides can not be specified.

Refresh period of data

• The table was extended by the year 2019 on 06 Aug 2021.
  Information for a new reporting period will be added as soon as it is available.
