Although air pollution is well known to be harmful to the lung and airways, it can also damage most other organ systems of the body. It is estimated that about 500,000 lung cancer deaths and 1.6 million COPD deaths can be attributed to air pollution, but air pollution may also account for 19% of all... cardiovascular deaths and 21% of all stroke deaths. Air pollution has been linked to other malignancies, such as bladder cancer and childhood leukemia. Lung development in childhood is stymied with exposure to air pollutants, and poor lung development in children predicts lung impairment in adults. Air pollution is associated with reduced cognitive function and increased risk of dementia. Particulate matter in the air (particulate matter with an aerodynamic diameter < 2.5 μm) is associated with delayed psychomotor development and lower child intelligence. Studies link air pollution with diabetes mellitus prevalence, morbidity, and mortality. Pollution affects the immune system and is associated with allergic rhinitis, allergic sensitization, and autoimmunity. It is also associated with osteoporosis and bone fractures, conjunctivitis, dry eye disease, blepharitis, inflammatory bowel disease, increased intravascular coagulation, and decreased glomerular filtration rate. Atopic and urticarial skin disease, acne, and skin aging are linked to air pollution. Air pollution is controllable and, therefore, many of these adverse health effects can be prevented.

Long-term exposure of humans to air pollution enhances the risk of cardiovascular and respiratory diseases. A novel Global Exposure Mortality Model (GEMM) has been derived from many cohort studies, providing much-improved coverage of the exposure to fine particulate matter (PM2.5). We applied the GE...MM to assess excess mortality attributable to ambient air pollution on a global scale and compare to other risk factors.
Methods and results
We used a data-informed atmospheric model to calculate worldwide exposure to PM2.5 and ozone pollution, which was combined with the GEMM to estimate disease-specific excess mortality and loss of life expectancy (LLE) in 2015. Using this model, we investigated the effects of different pollution sources, distinguishing between natural (wildfires, aeolian dust) and anthropogenic emissions, including fossil fuel use. Global excess mortality from all ambient air pollution is estimated at 8.8 (7.11–10.41) million/year, with an LLE of 2.9 (2.3–3.5) years, being a factor of two higher than earlier estimates, and exceeding that of tobacco smoking. The global mean mortality rate of about 120 per 100 000 people/year is much exceeded in East Asia (196 per 100 000/year) and Europe (133 per 100 000/year). Without fossil fuel emissions, the global mean life expectancy would increase by 1.1 (0.9–1.2) years and 1.7 (1.4–2.0) years by removing all potentially controllable anthropogenic emissions. Because aeolian dust and wildfire emission control is impracticable, significant LLE is unavoidable.
Conclusion
Ambient air pollution is one of the main global health risks, causing significant excess mortality and LLE, especially through cardiovascular diseases. It causes an LLE that rivals that of tobacco smoking. The global mean LLE from air pollution strongly exceeds that by violence (all forms together), i.e. by an order of magnitude (LLE being 2.9 and 0.3 years, respectively).

Secondhand smoke can infiltrate into other units through hallways and stairwells. Don’t be shy when it comes to your health. Talk to your building manager about making your apartment smokefree.
Pollution (dirty air) is a big trigger for asthma as it makes it difficult to breathe and affects the health of humans, animals, and plants. Avoiding pollution helps prevent asthma symptoms!

This manual has been designed to be used in conjunction with two earlier WHO publications, "Basic tests for pharmaceutical substances" (1986) and "Basic tests for pharmaceutical dosage forms" (1991). Most of the pharmaceutical substances and dosage forms covered are included in the WHO Model List of... Essential Drugs. The present volume describes procedures for testing a further 23 pharmaceutical substances and 58 pharmaceutical dosage forms and also for testing 4 medicinal plant materials.

The objective of this course is to provide high-level information and contextual understanding of WHO Standard Operating Procedures (SOPs) for Emergencies.
We will explore a range of topics, ranging from the Emergency Response Framework (ERF), to planning, grants and finance, procurement, risk mana...gement, rosters and deployment, and ethics.
Each module within this course is standalone. Therefore, you can take the modules in any order – with the exception of the Course Review. The Course Review is a question-based revision module that recaps the content covered in modules 1 to 10.
The target audience for this course is personnel who will be assigned by WHO to go on deployment in response to health emergencies.
The course is available in English and French
