UK companies secure chromate authorisations

The European Commission has granted authorisations for the use of toxic hexavalent chromate compounds to four UK firms, largely in the defence sector.

Permission to use ammonium dichromate – classified as carcinogenic, mutagenic, toxic to reproduction and sensitizing to the skin and respiratory system – has been handed to BAE Systems, Qioptiq Ltd and Display Technologies Ltd.
