The Pb concentration in curly kale, a marker food for atmospheric deposition of Pb, has decreased by a factor of approximately 8 in 2003 in comparison with the 1980s [1]. The reduction of the Pb content found in kale as well as in spinach (not shown) coincides with the reduction in Pb emissions from combustion of leaded petrol in Denmark and other European countries. The remaining...

In the following, standardised procedures for ryegrass and curly kale biomonitoring are presented, and the suitability of both methods illustrated by giving examples from own monitoring networks established in urban areas and around industrial emission sources in the vicinity of residential areas. Pros and cons of these methods will be discussed, and the need for further standardisation of such procedures as a pre-requisite for their extensive use in air quality monitoring networks in Europe and elsewhere will be outlined.
