An introduction to fighting pollution

Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives in it.

Think back to your school biology lessons and you may remember that plants turn carbon dioxide into oxygen through a process called photosynthesis.

However, this is not their only health benefit; vegetation and water also act as a natural filter, capturing harmful pollutants and toxins, which could otherwise cause life-threatening health problems.

Init is estimated there were 5, fewer respiratory hospital admissions, 1, fewer cardiovascular hospital admissions, 27, fewer life years lost and 1, fewer premature deaths as a result of natural pollution removal by plants across the UK.

Back to table of contents 2. Which pollution is the most harmful? This fine particulate matter has a diameter less than 2. These particles are so small that they can bypass the nose and throat and penetrate deep into the lungs and sometimes even the blood stream. This means the health effects can be quite serious and therefore the filtering of PM2.

This in turn results in large savings in healthcare costs. The savings from pollution capture of PM2. Pollution capture and value of pollution capture for PM2. Why is some nature more valuable than others? The amount of pollution that vegetation filters and the impact it has depends on a number of factors, which are incorporated into a scientific model.

Areas with busy traffic or factories, for example, are likely to produce high levels of pollution. If combined with high population density these are the areas likely to see the most hospital admissions and premature deaths. This means that vegetation in these locations has greater potential to prevent illness.

However, pollution is able to travel far from its source and affect other parts of the UK. Some pollutants such as ammonia, which contributes to forming PM2. Laurence Jones who led the project explains: Our work has shown that plants are removing pollutants right across the UK and this overall reduction in the levels of pollutants leads to a substantial health benefit.

This is reflected in figure 2 where the value of woodland is far higher than other habitats despite covering less land than farmland and grassland.

These values take into account the efficiency of the vegetation and the amount of vegetation in the UK. Even then, some trees are better at filtering pollution than others; conifers are good at removing particles as they stick to their waxy leaves while large trees like elms are efficient at reducing harmful gases because the tree canopy has a large surface area.

However, some species, including conifers release compounds that form the pollutant ozone, reducing their positive effects.

Annual value of pollution capture in UK Source: How much are we polluting the air? Air pollution remains a major problem in the UK despite a reduction in emissions since In Februarythe UK was issued a warning from the European Commission for failing to address repeated breaches of air pollution limits for nitrogen dioxide NO2 in 16 cities including London, Glasgow and Leeds.

Sulphur dioxide SO2 emissions have fallen the most since Figure 3this change can be linked to policy initiatives to discourage the use of high-sulphur fuels and the adoption of cleaner technologies, in particular to switch from coal to gas for electricity generation.

Pollution emitted by pollution type, to UK Source: Office for National Statistics Download this chart Image. Smaller particles are able to remain in the air for weeks and travel hundreds of miles so with the right weather conditions can travel to the UK from mainland Europe.

Nature is another source of pollution, sand, dust and sea salt amongst other natural sources can add to poor air quality. In addition to these direct emissions, particles can also be formed from the chemical reactions of gases, known as secondary particles.

This all makes for a complicated picture of UK air quality, with many different sources.

For information on atmospheric emissions and how these are changing in the UK see the latest release of the ONS Environmental Accounts.
