<p class="p__2">Impurities are either naturally taking place or added during synthesis of a chemical or industrial product. During production, impurities might be intentionally, mistakenly, undoubtedly, or incidentally included into the substance. The levels of pollutants in a product are usually defined in relative terms. Standards have been established by various companies that try to define the allowed levels of different impurities in a made item.</p>
<br>
<p class="p__3">Harmful pollutants [edit] Pollutants can be devastating when they obstruct the working nature of the material. Examples include ash and debris in metals and leaf pieces in blank white papers. The removal of pollutants is usually done chemically. For instance, in the manufacturing of iron, calcium carbonate is included to the blast furnace to eliminate silicon dioxide from the iron ore.</p>

<p class="p__5">The factor that it is difficult to get rid of impurities entirely is of thermodynamic nature and is anticipated by the second law of thermodynamics.
