General | Latest Info

Ambient is major cause of death and disease globally. Health effects range from increased hospital admissions and emergency room to increased risk of premature death. Estimate 4. 2 million premature deaths globally are linked to ambient pollution, mainly from heart disease, stroke, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections in children. 29 percentage of all deaths and disease from lung Cancer 17 percentage of all deaths and disease from acute lower respiratory infection 24 percentage of all deaths from stroke 25 percentage of all deaths and disease from ischaemic heart disease 43 percentage of all deaths and disease from chronic obstructive pulmonary disease pollutants with strongest for public health concern, include particulate matter, ozone, nitrogen dioxide and sulphur dioxide. Health risks associated with particulate matter of less than and 2. 5 microns in diameter are good document. Pm is capable of penetrating deep into lung passageways and entering bloodstream causing cardiovascular, cerebrovascular and respiratory impacts. In 2013, it was classified as cause of lung Cancer by WHOas International Agency for Research on Cancer. It is also most widely used indicator to assess health effects from exposure to environmental air pollution. In children and adults, both short and long - term exposure to ambient air pollution can lead to reduced lung function, respiratory infections and aggravated asthma. Maternal exposure to ambient air pollution is associated with birth outcomes, such as low birth weight, pre - term birth and small gestational age births. Emerging evidence also suggests ambient air pollution may affect diabetes and neurological in children. Considering precise death and disability tolls from many of conditions mentioned are not currently quantified in current estimates, with growing evidence, burden of disease from ambient air pollution is expected to greatly increase. Even though all populations are affected by air pollution, of ill - health is inequitable within and across countries. Most of disease burden is bear by low - and middle - income countries, as well as poor and marginalized populations. Who tend to live busy roads and industrial sites characterized by high levels of ambient air pollution. Nearly 90 percentage of 4. 2 million premature deaths due to ambient air pollution occur in low - and middle - income countries, with greatest burden in WHO Western Pacific and South - East Asia regions. Other susceptible groups include those with pre - existing lung or heart disease, as well elderly people and children. In children with developing lungs, air pollution exposure can cause both short - and long - term deficits in lung function, as well as long - term in lung growth rate. Improving air quality is, therefore, among measures with greatest potential impact on health equity. Large health benefits would occur for lower income groups, as well as children and elderly, WHO bear brunt of exposure to ambient air pollution or are most susceptible. Pollutants not only severely impact health, but also earthas climate and ecosystems globally.

Air Pollution

Everyone is exposed air pollution. Air pollution, even at low levels, has impact on human health. Science has clearly shown that Air Pollution Lead to disease, increased hospitalizations, and premature death. While air pollution is complex mixture of substances, most health effects are associated with major components of smog: fine Particulate Matter; Nitrogen Dioxide; ozone; and sulphur Dioxide. Even though air pollution levels are low in Canada compared with those in other countries, addressing air pollution remains priority for government of Canada. Find out how air pollution can affect your health and is at risk for getting sick.

Children

Children face special risks from air pollution because their lungs are growing and because they are SO active and breathe great of air. Just like arms and legs, largest portion childs lungs will grow long after he or she is born. Eighty percent of their tiny sacs develop after birth. Those sacs, called alveoli, are where life - sustaining transfer of oxygen to blood takes place. Lungs and their alveoli arent fully grow until become adults. 1 In addition, body defenses help adults fight off infections are still developing in young bodies. 2 Children have more respiratory infections than adults, which also seems to increase their to air pollution. 3 Furthermore, children do behave like adults, and their behavior also their vulnerability. They are for longer periods and are usually more active when outdoors. Consequently, they more polluted outdoor air than adults typically do.
