by growing the plants in empty places and building factories outside the cities

Hello, A control related to air quality is a complex set of specific techniques and measures identified and implemented to achieve reductions in air pollution to attain an air quality standard or goal.

For more info see below info.

Good luck!

An air quality monitoring device should be installed in the area. Awareness on the health implications of air pollution should be created in the area. Causes of air pollution in the area should be identified and appropriate sanctions taken by relevant authorities in order to reduce the menace. People should also wear safety kids capable of filtering the air to be inhaled.

awful conditions and many people are suffering from this killing problem!

One of the most important and vital issue in Iran!

Dear Parisa,

(1) Stop private car traffic in the city

(2) In Frankfurt and Heidelberg the construction of telecabins as a public transport system is being discussed

(3) Stop old and aging cars which do not meet today's emission regulations

(4) Use of solar power plants, electric vehicles and H2 driven vehicles

(5) Use of bicycles and electric bicycles on a special lane of motorways

(6) Use of renewable energy (wind, sun etc.)

...

All the best,

Gerhard

It's difficult to reduce personal health risks from air pollution.

by growing the plants in empty places and building factories outside the cities

In many areas of the world, concentrations of ambient air pollutants exceed levels associated with increased risk of acute and chronic health problems. While effective policies to reduce emissions at their sources are clearly preferable, some evidence supports the effectiveness of individual actions to reduce exposure and health risks. Personal exposure to ambient air pollution can be reduced on high air pollution days by staying indoors, reducing outdoor air infiltration to indoors, cleaning indoor air with air filters, and limiting physical exertion, especially outdoors and near air pollution sources. Limited evidence suggests that the use of respirators may be effective in some circumstances. Awareness of air pollution levels is facilitated by a growing number of public air quality alert systems. Avoiding exposure to air pollutants is especially important for susceptible individuals with chronic cardiovascular or pulmonary disease, children, and the elderly. Research on mechanisms underlying the adverse health effects of air pollution have suggested potential pharmaceutical or chemopreventive interventions, such as antioxidant or antithrombotic agents, but in the absence of data on health outcomes, no sound recommendations can be made for primary prevention. Health care providers and their patients should carefully consider individual circumstances related to outdoor and indoor air pollutant exposure levels and susceptibility to those air pollutants when deciding on a course of action to reduce personal exposure and health risks from ambient air pollutants. Careful consideration is especially warranted when interventions may have unintended negative consequences, such as when efforts to avoid exposure to air pollutants lead to reduced physical activity or when there is evidence that dietary supplements, such as antioxidants, have potential adverse health effects. These potential complications of partially effective personal interventions to reduce exposure or risk highlight the primary importance of reducing emissions of air pollutants at their sources.

Through cultivated several of the plants in empty regions and building factories outside the cities.

The burning fossil fuels, agriculture activities, deforestation, exhaust from factories, industries and car and even smoke from homes are the main causes of air pollution.

We have to minimize theses anthropogenic activities.
