7/8 2016 ADAC motorwelt: The article says that since 1 July 2016 cars are not allowed to Paris City, which were approved before 1997. After 2020 an even cars older than 10 years are not allowed. This is for conservation/ protection of environment.
Carbon Monoxide (CO) is a colourless, tasteless and odourless gas. It is a chemical compound of Carbon and Oxygen.
Carbon Monoxide (CO) and its association with carbon dioxides (CO2) and Oxygen (O2) and how they interact and do damage in and by exhaust gases: The exhaust gases of cars on the one hand contain a lot of carbon dioxide – which is harmless in the short term as long as enough oxygen is available. What is also present in the exhaust gas – also in much slower concentration – is carbon monoxide. That is much more dangerous: Carbon dioxide is simply inhaled and exhaled and does not react with the human body. Carbon monoxide is transferred to the red blood cells in the lungs and attaches there extremely tight. Normally Oxygen should be there in the lungs, but that does not work if Carbon monoxide has taken the place of oxygen. The red blood cells thus can not work for the internal breathing because they can not longer absorb oxygen! I.e. we can die from carbon monoxide polluting if carbon monoxide is not diluted from fresh air. (Information to me in April 2019.)
CO2 Emission in E-cars
is - as claimed by the producers - without any CO2 emissions. Carbon dioxide is a not visible heavy gas, weight in grams or tons. However in Germany E-cars are charged with CO2 emissions, since the Germans take into consideration the origin of the electricity. I.e. if the electricity is produced with burning of wood, oil, or other fossils as gas users can find this CO2 emissions at e-cars. This is to compare conventional cars and e-cars, as was informed at 10 Feb 2019.
CO2 Emissions, NOX and Particulate Matter Through Exhaust Gases or Fumes i
19 July 2017 Deutschlandfunk, a term clarification by Güther Hetzke / Christine Heuer: CO2 and NOX are gases. NOX are damaging the health. These NOX are mostly a man-made result, caused by burning of fossile energy as coal, oil and gases. In cities mainly Diesel cars are responsible for NOX. However also petrol cars are dangerous for the health because of the fine dust due to the tire abrasion and other reasons. In higher concentration they do damage to the lungs and thus later can cause heart problems. They do damage also to plants. NOX are part of the Particulate Matter Fumes, which is in general made by dust and erosions of the streets or by the tires’ abrasion. All these are doing damage to health. Carbon dioxides (CO2) are a part of nature, however in high concentration also can damage the health. CO2 is produced mainly by petrol cars or petrol driven engines.
