Project: Chromium speciation in water and welding dust.
- project duration
- 01-OCT-93 – 31-DEC-99
- Tne different toxicity and bioavailability of Cr III and Cr VI have been a health concern for some time, necissitating their monitoring in drinking water and indoor air loaded with welding fumes. At present the reliability of the CrIII and CrVI determinations have been very unsatisfactory. There is an urgent need for ref.mat.to enable labs to check their performance.The preparation of a lyophilised water mat. representative for nat. and tap water and a filter loaded with welding dust are envis.
