Three methods for determining organic matter are given below. The first is the classical Walkley-Black method.... The third method of estimating soil organic matter, loss of weight on ignition, is included because of hazards associated with the use of Cr2O72-. This ion in a strong acid medium is a powerful oxidant. It is corrosive to skin, mucous membranes, the respiratory tract and the gastrointestinal tract. It may create a cancer risk. Some municipalities restrict the amount of Cr that can be discharged into the sewage system. For these reasons, alternative procedures not involving Cr2O72-have been sought.  1, fiche 2, Anglais, - loss%20of%20weight%20on%20ignition%20method

An activated sludge system for treating domestic sewage or strong industrial waste, in which air is blown into a shaft or borehole of 0. 4 to 10 m diameter, sunk 60 to 300 m into the ground. The depth and consequent high pressure are an advantage, because for every 10 m depth the pressure rises by 1 atm, which correspondingly increases the solubility of oxygen.  1, fiche 3, Anglais, - deep%2Dshaft%20system
