They can take the form of calcium and magnesium salts, carbon dioxide, sodium salts, silicates, ferrous and ferric iron compounds, chlorides, aluminium phosphates and nitrates from a range of different environments and conditions.
Inorganic compound is any compound that lacks a carbon atom. There are a small number of inorganic compounds that actually do contain carbon, given its propensity for forming molecular bonds; these include carbon monoxide and carbon dioxide, to name a few.
Inorganic compounds are often quite simple, as they do not form the complex molecular bonds that carbon makes possible. A common example of a simple inorganic compound would be sodium chloride, known more commonly as household salt. This compound contains only two atoms, sodium (Na) and chlorine (Cl).

Even at trace levels, organic compounds can affect both organic and biochemical reactions as they often act as catalysts.
