The big cities of China, EE. UU and the EU exhales 54% of the world’s CO 2 emissions into the atmosphere , according to the Environmental Protection Agency (EPA). Its nearly 1,380 million inhabitants have good reason to worry about the quality of the air they breathe.

China leads the ranking of countries emitting carbon dioxide (CO 2 ), followed by EE. UU and of the EU member states. The powerful greenhouse gas is one of the substances that contribute most to global warming and climate change, but it is not the only one. Many other compounds, known as climate pollutants, influence the amount of solar energy retained by the Earth … and cause many health problems.
HOW IS THE AIR QUALITY MEASURED IN THE CITIES?
At the end of 2017, the European Environment Agency (EEA) and the European Commission launched a new European Index of Air Quality (ICA), which allows users to check their quality in the more than 2,000 measurement stations distributed throughout Europe. This index, which provides up-to-date information on air quality in the 33 member countries of the EEA, includes national profiles since local public administrations have to adapt their measures to consider factors such as demographics, transport infrastructures, etc. These measurements monitor the air quality standards and control the ozone (O 3 ) levels of nitrogen dioxide (NO 2)), carbon dioxide (CO 2 ), sulfur dioxide (SO 2 ) … and all the pollution generated by particles that can represent serious health risks.
The EPA environment agency is responsible for the US index. UU while the National Center for Monitoring the Environment in China (CNMMC) is the body responsible for compiling, analyzing, adding and publishing the data of the different air indicators in that country.
HOW CAN I FIND OUT AIR QUALITY IN MY CITY?
On websites, through apps … and even Google gives us that information. Simply typing air quality, followed by the name of the city, to show us a bar that indicates in real time the air quality and the main pollutant in a location. This gives the value of the Air Quality Index (ICA) or Air Quality Index (AQI) from the measurement stations distributed in the cities and, when there is no ground level, from the satellites.
MONITOR AIR QUALITY IN CLOSED SPACES
Tobacco smoke aggravates respiratory problems; irritates the eyes; It can generate headache, cough and sore throat.
Allergens and pollens aggravate respiratory problemsand cause coughing, chest tightness, eye irritation and skin rashes.
Carbon monoxide (CO) and nitrogen dioxide (NO 2 ) CO can be lethal in high doses; causes headache, dizziness and nausea.
The humidity generated by bacteria, fungi and molds when growing in closed spaces can cause respiratory problems, allergies and asthma.
Radon gas can penetrate the building through all openings, however minimal. It can be harmful to the lungs.
ATTENTION TO THE AIR QUALITY WITHIN THE HOUSING!
The population that lives in urban areas spends 90% of their time indoors, in their home or place of work. Thus, 2,600 million inhabitants are at risk of suffering from the sick building syndrome, a term used by the World Health Organization to define diseases caused or stimulated by air pollution in enclosed spaces.
HOW DOES HEALTH POLLUTION AFFECT?
95% of the world’s population lives in areas that do not meet the standards of healthy air, according to the State of Global Air report from the Health Effects Institute. Cities, where more than half of the world’s 7,500 million inhabitants live, are the breeding ground for pollution, an important factor in mortality, which is only overcome by hypertension, unhealthy diet and tobacco.
The main effects of air pollution on health are:
