Air Quality
The quality of air has long become the principal good health requirement. ‘Quality
Standards Regulations 2000,’ the UK’s quality air legislation which got updated in the year 2010
controls some pollutants which get regarded as dangerous to the environment and human health.
This legislation has EU values and limits or control Sulphur dioxide pollution, nitrogen
dioxide/oxides and particulate matter like PM2.5 and PM10, benzene, lead, Carbon Monoxide,
ozone and benzo (a) pyrene pollution (Friis, 2012). Much attention to the quality of air gets put
on particulate matter and nitrogen dioxide. Particulate matter is a mixture of particles which are
non-gaseous and have unique chemical and physical composition (Friis, 2012). The PM becomes
ranked by the particulate’s size. There are several sources of PM for instance from road traffic,
exhaust emissions, brake wear, and tire as well as dust from the surface of roads. Further, there
are boilers and older furnaces which affect the quality of air too mainly in houses. Poor air
quality can compromise the well-being and health of people (Marmot and Wilkinson, 2005).
Evidence shows that there are high NO2 levels on the roads of Barking and Dagenham
above limits which get recommended. Scientists are still applying their statistical tools in
attempting to understand how different factors affect mortality. They have found that Barking
and Dagenham is number 14 least places in London regarding air quality (Stewart and Bushell,
2011). Prolonged exposure to air that is polluted has been found to result in chronic illnesses and
can raise respiratory diseases risks. It gets estimated that 4,267 deaths occurred in 2008 in
London due to PM2.5 exposure (Friis, 2012). However, these results do not link to real people as
it is a mere statistical construct with amalgamated health effects due to air pollution. Because
everybody inhales the same air, realistic interpretations are that potential risks get distributed
evenly in the entire population with the cumulative mortality outcomes of the concentration
equal to the death number or rate. High levels of NO2 can cause inflammation in an individual’s
breathing tubes, and extended exposure can harm lung function as well as cause respiratory
symptoms or asthma (Friis, 2012). Cardiovascular and respiratory conditions get aggravated by
PM where smaller PM or particles go deeper and become deposited inside respiratory tracts.
Polluted air affects individuals with heart challenges, those working close to the contaminated
area as well as those with respiratory problems (Public health England, 2014).
