what's in our air? 50 is good, 100 is unhealthy, 300 is hazardous.
Air Quality Aware data, GIS, mapping and spatial analytics
the indices used to measure air quality are:
ground level ozone, particulate matter (pm2.5 and pm10), carbon monoxide, sulphur dioxide and nitrogen dioxide.
air quality index is used for reporting air quality. AQI 50 is good, 100 is unhealthy, 300 is hazardous.
fine particulate matter (PM2.5) <2.5 microns
particulate matter will take your breath away and make you choke for air. Tiny airborne particles, known as PM2.5, are fine particulates less than 2.5 microns in diameter (1/30th the width of a human hair). Fine particulates cause serious health affects because they lodge deeply into the lungs and pass through to the bloodstream, causing respiratory illness, asthma, lung disease and heart disease.
sources of fine particulates are any type of common combustion including power plants, car and truck exhaust, restaurant grilling and wood burning, grocery store food production, grilling, wood burning, residential wood burning, BBQ open-air wood burning, and fast food charbroiling.
danger of smoke - do you burn wood like a caveman?
besides irritating the respiratory tract and the eyes, pollutants in the haze can cause serious long-term damage to health.
in Malaysia, because of the farming technique of clear-cutting the haze reached 208 on the Air Pollutants Index (API) in several districts. The clear-cutting causes wildfires which causes more and more smoke, which poisons more and more air.
global levels of carbon dioxide (CO2) passed 400ppm, while 100ppm is considered an unhealthy amount of greenhouse gas (ghg).
air pollution can cause hypertension, diabetes and respiratory diseases, conditions that doctors are starting to link to higher mortality rates for covid-19.

it's us, it's bad, and we can fix it
we must ensure that air pollution standards protect the public's health. Science magazine
we can reduce air pollution by setting air quality standards, monitoring levels of air pollutants, and enforcing regulations. The goal is to reduce air pollution of fine particulates and noxious gases. The only way to get there is to immediately transition the global economy away from fossil fuels and into renewable energy, energy efficiency, and sustainable farming practices.
burning coal, oil, ngas is damaging the atmosphere
yes, the world needs energy, and we can use clean energy like solar and wind energy, instead of coal, oil, and methane-producing natural gas (ngas). Pollution from burning coal to make electricity is damaging the atmosphere. Leaks from oil production and transportation are damaging the oceans and rivers which is destroying our drinking water. Combusting fuel in cars and trucks is producing tailpipe emissions that react with sunlight to form smog which is causing the atmosphere to warm.
we must oppose Trump's systematic program to rollback current federal environmental safeguards.
global levels of carbon dioxide (CO2) passed 400ppm. Climate change is intensifying and the stability of the planet is at stake. Greenhouse gas emissions must be reduced by 80% by 2050.
parts per million by volume are the units of measure for the air quality standards for pollutants. 100ppm is considered an unhealthy amount of greenhouse gas (ghg). 350ppm is the safe upper limit. The earth's atmosphere hit 400ppm in March 2015, and 403ppm in 2017.
please note that trees eat carbon dioxide CO2 and give us oxygen O2 which we need to breathe or else we die, like immediately.

ghg CO2 and CH4
greenhouse gases (ghg) are noxious gases like carbon dioxide (CO2) and methane (CH4) that trap heat in the atmosphere. Heat in the atmosphere negatively affects the climate for human life. A 1°C rise in the temperature of the Earth is already causing storm surges, floods and wildfires.
carbon dioxide (CO2) and methane (CH4) are potent greenhouse gases that absorb the sun's heat, thus adversely warming the atmosphere.
methane is 30 times more potent than CO2 and is a major contributor to climate change. Methane is the main component of natural gas (ngas).
methane is the primary component of natural gas, a common fuel source. The oil and gas industry produce industrial emissions of methane pollution. Methane is currently allowed to leak into the air in the fracking process, and 25% gets leaked into the atmosphere during distribution.
WHO (World Health Organization) has been campaigning to decrease toxic pollution around the globe, educating the public on the dangers to health. Its guidelines for PM2.5 is no more than 10 micrograms per cubic meter. ug/m3 is a measurement of density.
nitrogen dioxide, NO2
nitrogen dioxide, NO2, a key contributor to smog and a major health hazard, is the gas that is emitted by motor vehicles, power plants and other industrial facilities.
we need enhanced methods to monitor and to regulate industrial and domestic smoke. Particulate matter, PM2.5 and nitrogen dioxide, NO2.
