This map provides a picture of the toxic pressure of ammonium/ammonia in Dutch surface water. Toxic pressure is important because chemical pollution affects aquatic communities...

The NAV (Nitrophil Indication Value) is a measure of the ammonia load and is based on the occurrence of ammonia-loving lichens. High values ​​indicate where the environment is...

The NAV (Nitrophil Indication Value) is a measure of the ammonia load and is based on the occurrence of ammonia-loving lichens. High values ​​indicate where the environment is...

In order to achieve the objectives of European nature policy, nitrogen precipitation in Natura2000 areas must be reduced. Agreements have been made within the framework of the...

Raw accident-aided hourly values ​​of ammonia (NH3) at ground level in the outside air measured in the National Air Quality Monitoring Network (LML). Ammonia is gaseous and is a...

The map shows how much ammonia is emitted. Ammonia is mainly released during agriculture, but there are also chemical processes in which ammonia is released. The emissions are...

The occurrence of ammonia-loving lichens, expressed in the Nitrophil Indication Value (NAV). Change of indication value in the period 91-98 per hour pen. An increase in NAV...

In 2007, the province of Drenthe commissioned Alterra to carry out an exploratory study into nitrogen flows and emissions from agriculture, and the possible effects of measures...

Ammonia (NH3) emissions to air from all sources in 2014 in kg/km2 per year. Emission registration 1990 - 2014. (established 2016)

Shows the location of the sample points of the lichen research that has been carried out four times in Drenthe since 1991. Lichens are an important indication of the pressure on...

The AIW (Acidophilic Indication Value) is a measure of the ammonia load and is based on the occurrence of lichens that are sensitive to ammonia. High values ​​indicate where the...

EHS with indication "area sensitive to acidification" according to the Ammonia and Livestock Farming Act (WAV).

In order to achieve the objectives of European nature policy, nitrogen precipitation in Natura2000 areas must be reduced. Agreements have been made within the framework of the...

The historical series of nitrogen deposition contains the depositions (mol/hectare/year) per square kilometer from 2005 to 2021. The nitrogen deposition for historical years is...
