Again a picture of a year ago, one of the most beautiful days for photographers, the winter was wonderful, a very strong blue sky, this get we one or two days per year, sometimes also two year wait for this same weather.

The trees are wonderful white of smog, a pity for our health, we got one advice remain in your house! This was the advice of the government.


A pity for us nature the lovely nature was a result of the bad condition of the air, these air come from Germany and perhaps further out of the East countries, also a little bit of us own industrial in Belgium.


History of the smog:

Photochemical smog
In the 1950s a new type of smog, known as photochemical smog, was first described.
This forms when sunlight hits various pollutants in the air and forms a mix of inimical chemicals that can be very dangerous. A photochemical smog is the chemical reaction of sunlight, nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the atmosphere, which leaves airborne particles (called particulate matter) and ground-level ozone.

Nitrogen oxides are released by nitrogen and oxygen in the air reacting together under high temperature such as in the exhaust of fossil fuel-burning engines in cars, trucks, coal power plants, and industrial manufacturing factories. VOCs are released from man-made sources such as gasoline (petrol), paints, solvents, pesticides, and biogenic sources, such as pine and citrus tree emissions.


I hope you like it of these winter picture.
