&lt;br /&gt;
&lt;em&gt;Ammonia concentration in the atmosphere over India is the highest in the world due to cattle population and excessive fertilizer use, says study &lt;br /&gt;
&lt;/em&gt;&lt;br /&gt;
A satellite study of airborne ammonia gas has revealed four major hotspots over productive agricultural regions across the world. Increased atmospheric ammonia is linked to poor air and water quality.&lt;br /&gt;
&lt;br /&gt;
Using data from NASA&amp;rsquo;s Atmospheric Infrared Sounder satellite instrument, researchers led by the University of Maryland (UMD), discovered increased ammonia concentrations from 2002 to 2016 over agricultural centres in the US, Europe, China and India. The study was published last month in the journal, Geophysical Research Letters.&lt;br /&gt;
&lt;br /&gt;
&lt;em&gt;Harmful effects&lt;br /&gt;
&lt;/em&gt;&lt;br /&gt;
Increased ammonia is linked to fertilizers, livestock animal wastes, changes in atmospheric chemistry and warming soils that retain less ammonia.&lt;br /&gt;
&lt;br /&gt;
Gaseous ammonia is a natural part of the Earth&amp;rsquo;s nitrogen cycle, but excessive ammonia is harmful to plants, the study adds. Ammonia gas can also fall back to Earth and waterbodies, where it contributes to harmful algal blooms and &amp;ldquo;dead zones&amp;rdquo; with dangerously low oxygen levels.&lt;br /&gt;
&lt;br /&gt;
&amp;ldquo;To control ammonia-related pollution, it is necessary to regulate fertilizer waste and agricultural residue burning. Increase in fertilizer use is the leading cause behind the increase of gaseous ammonia in the atmosphere. Except for a few countries in Europe, ammonia emission is not regulated. There is a growing awareness on how ammonia in the atmosphere affects the ecosystem and air and water quality, Juying Warner, associate research scientist in atmospheric and oceanic science at UMD, told Down To Earth.&lt;br /&gt;
&lt;br /&gt;
According to researchers, the study results could help formulate strategies to control ammonia pollution near major agricultural areas.&lt;br /&gt;

&lt;em&gt;Ammonia concentration in the atmosphere over India is the highest in the world due to cattle population and excessive fertilizer use, says study &lt;br /&gt;
&lt;/em&gt;&lt;br /&gt;
A satellite study of airborne ammonia gas has revealed four major hotspots over productive agricultural regions across the world. Increased atmospheric ammonia is linked to poor air and water quality.&lt;br /&gt;
&lt;br /&gt;
Using data from NASA&amp;rsquo;s Atmospheric Infrared Sounder satellite instrument, researchers led by the University of Maryland (UMD), discovered increased ammonia concentrations from 2002 to 2016 over agricultural centres in the US, Europe, China and India. The study was published last month in the journal, Geophysical Research Letters.&lt;br /&gt;
&lt;br /&gt;
&lt;em&gt;Harmful effects&lt;br /&gt;
&lt;/em&gt;&lt;br /&gt;
Increased ammonia is linked to fertilizers, livestock animal wastes, changes in atmospheric chemistry and warming soils that retain less ammonia.&lt;br /&gt;
&lt;br /&gt;
Gaseous ammonia is a natural part of the Earth&amp;rsquo;s nitrogen cycle, but excessive ammonia is harmful to plants, the study adds. Ammonia gas can also fall back to Earth and waterbodies, where it contributes to harmful algal blooms and &amp;ldquo;dead zones&amp;rdquo; with dangerously low oxygen levels.&lt;br /&gt;
&lt;br /&gt;
&amp;ldquo;To control ammonia-related pollution, it is necessary to regulate fertilizer waste and agricultural residue burning. Increase in fertilizer use is the leading cause behind the increase of gaseous ammonia in the atmosphere. Except for a few countries in Europe, ammonia emission is not regulated. There is a growing awareness on how ammonia in the atmosphere affects the ecosystem and air and water quality, Juying Warner, associate research scientist in atmospheric and oceanic science at UMD, told Down To Earth.&lt;br /&gt;
&lt;br /&gt;
According to researchers, the study results could help formulate strategies to control ammonia pollution near major agricultural areas.&lt;br /&gt;

&lt;em&gt;Ammonia concentration in the atmosphere over India is the highest in the world due to cattle population and excessive fertilizer use, says study &lt;br /&gt;
&lt;/em&gt;&lt;br /&gt;
A satellite study of airborne ammonia gas has revealed four major hotspots over productive agricultural regions across the world. Increased atmospheric ammonia is linked to poor air and water quality.&lt;br /&gt;
&lt;br /&gt;
Using data from NASA&amp;rsquo;s Atmospheric Infrared Sounder satellite instrument, researchers led by the University of Maryland (UMD), discovered increased ammonia concentrations from 2002 to 2016 over agricultural centres in the US, Europe, China and India. The study was published last month in the journal, Geophysical Research Letters.&lt;br /&gt;
&lt;br /&gt;
&lt;em&gt;Harmful effects&lt;br /&gt;
&lt;/em&gt;&lt;br /&gt;
Increased ammonia is linked to fertilizers, livestock animal wastes, changes in atmospheric chemistry and warming soils that retain less ammonia.&lt;br /&gt;
&lt;br /&gt;
Gaseous ammonia is a natural part of the Earth&amp;rsquo;s nitrogen cycle, but excessive ammonia is harmful to plants, the study adds. Ammonia gas can also fall back to Earth and waterbodies, where it contributes to harmful algal blooms and &amp;ldquo;dead zones&amp;rdquo; with dangerously low oxygen levels.&lt;br /&gt;

Satellite study finds ammonia hotspots over agricultural areas -Deepanwita Niyogi

-Down to Earth Ammonia concentration in the atmosphere over India is the highest in the world due to cattle population and excessive fertilizer use, says study A satellite study of airborne ammonia gas has revealed four major hotspots over productive agricultural regions across the world. Increased atmospheric ammonia is linked to poor air and water quality. Using data from NASA’s Atmospheric Infrared Sounder satellite instrument, researchers led by the University of Maryland (UMD), discovered increased ammonia concentrations from 2002 to 2016 over agricultural centres in the US, Europe, China and India. The study was published last month in the journal, Geophysical Research Letters. Harmful effects Increased ammonia is linked to fertilizers, livestock animal wastes, changes in atmospheric chemistry and warming soils that retain less ammonia. Gaseous ammonia is a natural part of the Earth’s nitrogen cycle, but excessive ammonia is harmful to plants, the study adds. Ammonia gas can also fall back to Earth and waterbodies, where it contributes to harmful algal blooms and “dead zones” with dangerously low oxygen levels. “To control ammonia-related pollution, it is necessary to regulate fertilizer waste and agricultural residue burning. Increase in fertilizer use is the leading cause behind the increase of gaseous ammonia in the atmosphere. Except for a few countries in Europe, ammonia emission is not regulated. There is a growing awareness on how ammonia in the atmosphere affects the ecosystem and air and water quality, Juying Warner, associate research scientist in atmospheric and oceanic science at UMD, told Down To Earth. According to researchers, the study results could help formulate strategies to control ammonia pollution near major agricultural areas. Please click here to read more.
