analysis of sugar cane and sugar beet
Kurzfassung
Lead acetate can be replaced by aluminium sulphate in analysing sugar cane and sugar beet. Using alternative analytical methods that do not involve lead acetate is also possible.

Gefahrstoffbeurteilung
Substance to be substituted: Lead acetate basic may damage the unborn child and is suspected of damaging fertility, is very toxic to aquatic life, is very toxic to aquatic life with long lasting effects, is harmful if swallowed, is harmful if inhaled and may cause damage to organs through prolonged or repeated exposure. Alternative substances: Aluminium sulphate and diatomite ha no harmonised classification according to Annex VI of Regulation (EC) No 1272/2008 (CLP Regulation).
Beschreibung der Substitution
Lead acetate basic is used as clarifying agent in the polarisation method (visible light range) for analysing sucrose in sugar cane and beet juice. As it is reprotoxic and a suspected carcinogen it should be substituted. It can be replaced by aluminium sulphate. In the case of very turbid juices, diatomite may be used to improve clarity. Avoiding lead acetate may be also achieved by choosing a different type of analytical method: filtering the juice with diatomite and then using a polarimeter at 825 nm or using infrared spectrophotometry. All these methods represent alterations of the official method in France and therefore need to be validated.
Bewertung des Falls/der Substitution
Aluminium sulphate and diatomite can be used to replace more hazardous lead acetate. If the diatomite is of the flux-calcined type it may contain high levels of crystalline silica, a carcinogen. The consequences of the use of diatomite, which may contain carcinogenic substances, cannot be foreseen here, so further research is required.
