What Is The Impact Of Pollution On The Environment – Most of the air pollution, harmful gases, and airborne particles that affect national parks are created outside park boundaries.
Mobile sources account for more than half of all air pollution in the United States and the primary mobile source of air pollution is the automobile, according to the Environmental Protection Agency. Stationary sources, such as power plants, emit large amounts of pollution from a single location, they are also known as point sources of pollution. Area sources are made up of many smaller pollution sources that are not a big problem by themselves, but when considered as a group, they can be. Natural sources can sometimes be significant, but usually do not create ongoing air pollution problems as the other source types can.
What Is The Impact Of Pollution On The Environment
Pollution from man-made and natural sources is often created in one place and transported through the air. Sometimes chemical reactions in the atmosphere change pollutants before they are deposited. Pollutants in the air can create haze, making it harder to see, and pollutant precipitation can have biological effects. areas experience these effects just like other places. Location and even the time of year can determine which pollution sources are most important to each park.
How Does Air Pollution Affect The Economy?
Parks downwind of power plants that lack modern pollution controls can increase smog. Exhaust pipes from cars and trucks, as well as industrial processes such as oil and gas development, give rise to increased ozone concentrations. Summertime wildfires can also reduce visibility in areas. There are even examples of pollutants originating from other countries and transported thousands of kilometers arriving at parks. The effects of this pollution can be seen as haze and through negative biological effects. Learn more about the effects of air pollution on nature and visibility, and human health. Besides affecting human health, air pollution can also be harmful to our natural environment. Pollutants in the air can be toxic to sensitive plants and trees, while pollutants in rainfall damage habitats by depositing acid or excess nutrients. Water bodies such as rivers and lakes are also susceptible to the effects of air pollution.
The most important air pollution to our natural environment occurs when reactive nitrogen compounds, such as ammonia and nitrogen oxides, are deposited on sensitive sites. Deposition can occur through direct contact between polluted air and plants. This type of deposition is called ‘dry deposition’ and it usually happens near pollution sources.
Deposition also occurs when pollutants are dissolved in precipitation (rain and snow), which falls on sensitive sites. We call this ‘wet precipitation’ and it can happen at long distances from the pollution source.
Ammonia is by far the largest contributor to nitrogen deposition and comes from agricultural activities such as livestock housing, slurry/manure storage and spreading and fertilizer use. More information on ammonia emissions in Northern Ireland can be found here.

Another source of nitrogen deposition is from nitrogen oxides, which are produced from road transport (petrol and diesel engines) and some types of industry.
Sulfur dioxide is another air pollutant that has harmful effects on vegetation and is produced from burning fuels, especially coal.

Northern Ireland has 294 Areas of Special Scientific Interest, 54 Special Areas of Conservation and 16 Special Protection Areas designated as being in need of protection because of the importance of the species and habitats they support. Sites include peatlands, native woodlands, species-rich grasslands and freshwater and coastal habitats. For more information on protected sites, see here.

Ammonia can have a direct toxic effect on sensitive vegetation, such as lichens and mosses. Ammonia and nitrogen deposition reduce plant species richness and diversity, favoring species tolerant of excess nutrients. This leads to changes in plant and animal communities within our habitats and can also change their ecosystem function. Peatlands, for example, sequester carbon and are therefore crucial in the fight against climate change. If peatlands are damaged by ammonia and nitrogen deposition, they will not be able to store carbon as effectively.
DAERA monitors the condition of designated sites, and assessments can help identify where air pollution damage is a contributing factor to habitat damage and species loss.
In collaboration with partners UK Center for Ecology and Hydrology, Ulster Wildlife and the National Trust, NIEA’s Air Quality and Biodiversity Unit delivers a program of monitoring and evidence work. The work aims to identify and quantify sources of atmospheric nitrogen inputs to the NI-designated site network, to inform mitigation strategies and to evaluate how these natural N-poor ecosystems are affected by the addition of nitrogen.
Ammonia concentrations have been monitored at Ballynahone Bog since September 2014. Ammonia monitoring has been ongoing since June 2020 on an additional seven SACs (Curran Bog, Garry Bog, Moneygal, Peatlands Park, Sliabh Beagh, Cuilcagh Mountain and Turmennan). At Cuilcagh SAC and Ballynahone Bog, ammonia monitoring is accompanied by wet deposition monitoring. From July 2022, ammonia monitoring was also started at Murlough SAC.

Most ammonia air pollution samples are exchanged at monthly intervals. This monitoring corresponds to the UK National Ammonia Monitoring Network (running since the 1990s) in addition to a network of 25 rural location sites managed by AFBI.

Image on the right shows a wet deposition monitor at Ballynahone Bog: rainfall is collected and then samples are taken every month to be analyzed for the presence of nitrogen pollution.
Biomonitoring is also carried out at a number of sites to determine the effect of nitrogen on vegetation. Samples for leaf analysis are collected in winter or spring, before temperatures rise and growth begins.

As the Statutory Nature Conservation Body, NIEA is consulted on planning proposals to identify any potential risks to the natural environment. Through this process, potential impacts of air pollution to protected sites can be identified. Standing advice is available here.
A new integrated air pollution assessment tool, UK AERIUS, is currently in development. The project is led by JNCC, with funding from DEFRA and DAERA. Find out more here.

Air Pollution And Climate Change: Impact Today And Future
NIEA Natural Environment Division led an evidence program to assess and mitigate the impact of ammonia and nitrogen (N) deposition on Northern Ireland’s natural ecosystems. This work is in collaboration with the UK Center for Ecology and Hydrology (UKCEH) and project partners: Ulster Wildlife, National Trust, Monaghan County Council and Fermanagh and Omagh District Council.

Pollution occurs when a quantity of any substance or any form of energy is placed into the environment at a rate faster than it can be dispersed or safely stored. The term
Understanding The Causes And Effects Of Environmental Pollution
Can refer to both artificial and natural materials that are created, consumed and discarded in an unsustainable manner.
Air pollution, water pollution and soil pollution are three main forms of environmental pollution. Pollution can also refer to excessive human activity, such as light and noise pollution, or to specific pollutants such as plastic or radioactive material. Learn more in this infographic.
Air pollution is the main cause of climate change. Human activities such as the burning of fossil fuels and mass deforestation lead to the increase of carbon dioxide in the atmosphere, which traps heat in the atmosphere through a process called the greenhouse effect. It affects climate patterns and sea levels around the world.
Pollution can be reduced through processes such as recycling and the proper treatment of water and toxic waste. Reducing corporate fossil fuel extraction is another way to combat air pollution. According to
