How can you tell smog from air pollution?

You will recognize it by its color and smell

The main causes of excessive air pollution are industry and traffic, followed by the heating season and individual fireplaces. Weather conditions such as low air pressure only make the whole situation more difficult.

For example, some parameters accurately show that the concentration of pollution increases in the late afternoon, when people return from work, or when they heat their homes. Then this concentration decreases around midnight and increases again in the early hours of the morning.

The first thing meteorologists should do is to inform citizens in time when an increased concentration of air pollution is expected. This should be done especially for chronic lung patients, asthmatics, the elderly and children. Doctors even advise that in those situations it is better for people to stay in their homes where the air is stagnant but not polluted than to be exposed for a long time outside and inhale the smog.

Meteorologists say that the fog appears when the temperatures are low and the air humidity is high, because they are characteristic for the night and morning hours during autumn and winter, Telegrafi reports.

Fog may not be the result of pollution, but suitable meteorological conditions that lead to a significant increase in pollution also bring fog.

Fog and air pollution go together because there is a lower layer of air in the atmosphere, the height of which is an average of one kilometer.

In certain meteorological conditions it can be lower and thinner. When that layer becomes thinner, the concentration of air pollution also increases. And when fog and dirt mix, air pollution is created.

The main difference is in color, because true fog is completely white, white as snow, and when the sun shines through it, it is almost blinding white. While in the case of air pollution there is always a color, a yellow, green color, because the pollution is actually condensed water. Very small droplets of condensed water in which the pollution has dissolved.

Another important difference is the wind. So why shouldn't mist smell because it's from pure water?

Air pollution is gray in color, and real fog, rarely seen in cities, is white as snow. In cities, we mostly don't see real fog, but a combination of fog and pollution. Unfortunately, when we are in the city we live in polluted air, not fog.

The same conditions lead to increased pollution, also lead to the appearance of fog. When these two mix, then we will have air pollution.

The strengthening of the temperature inversion is also helped by the fact that the wind is weak. When we have a suitable temperature inversion, there are suitable conditions for the lower layer of the atmosphere to thin and the concentration of pollutants to rise and the appearance of fog.

When there is fog, it cannot rain, but they can be rains of weak intensity.

Pollution is more visible because of the fog.

The telltale sign of pollution in fog is its color. The weirder the color, the more yellow, green, gray, the more pollution there is in the fog. /Telegraph/
