The importance of the rest is less before these two. Although there are several, the most important, in terms of their polluting effects, are nitrogen dioxide, NO2 and nitric oxide, NO. Nitrogen oxides form an important group of polluting gases. In the atmosphere, hydrogen sulfide is easily transformed into sulfur dioxide, which increases the concentration in the atmosphere. As for the anthropogenic release of hydrogen sulfide, it is classic in the paper industry and also in refineries. It occurs naturally by rotting organic matter, at the bottom of lakes and rafts that are in anaerobic conditions, in the absence of oxygen. Hydrogen sulfide, SH2 at high concentrations, is a toxic gas that produces an unpleasant and characteristic odor. This acid carried by rainwater has corrosive effects produced by acid rain on natural resources. On the other hand, sulfur trioxide does not remain long in the atmosphere, since it is highly hygroscopic and in contact with humanity it is transformed into sulfuric acid. Under certain circumstances, chemical reactions occur in which this dioxide can be transformed into trioxide. Sulfur dioxide in high concentrations can be an irritating gas that causes alterations in the eyes and respiratory tract. The two are issued together and the proportion of the second is from 1% to 5% of the total. The emission of trioxide is much higher quantitatively than that of dioxide. The most important sulfur oxides in terms of air pollution are sulfur dioxide, SO2 and sulfur trioxide, SO3. The main sources are thermal power plants, various industrial processes, automobile traffic and certain heaters. Within sulfur compounds, oxides originate from fossil fuel combustions that contain sulfur, such as coal, oil and some derivatives. In the case of gases, the units are the parts per million.

Unfortunately, if this school or place of business doesn't stop people from abusing our resources, we don't have any other way to put an end to it. When we get more abuse from a single IP address than we do legitimate traffic, we really have no choice but to block it.

Unfortunately, so do spammers and hackers. IP bans will be reconsidered on a case-by-case basis if you were running a bot and did not understand the consequences, but typically not for spamming, hacking, or other abuse.
