Biomonitoring

Active and passive biomonitoring

Feld und Grasmuster

The contamination of vegetation through air pollutants and its integration into the food chain, e.g. in the form of animal feed, are of great significance in the field of practical air pollution control. Through active and passive biomonitoring cheap protection goal oriented details can be provided with regard to possible risks or damage. People, animals, plants and soil are the protection goals.

Pollutant monitoring and evaluation from the agricultural perspective

Active biomonitoring with standardised grass culture: short rotation ryegrass is brought into the test study area and left exposed there on a carrier device. After pre-determined periods of growth it is checked for pollutants.

Passive monitoring with meadow grass and tree leaves: the plant samples (meadow grass, tree leaves) are taken directly from the test study area and checked for pollutants.

The emission measurements performed using plants are conducted at an accredited inspection body as per EN ISO/IEC 17020.

Orientation values

Orientation values for maximum background values (OMB)

The results of several years of measurements from rural locations in Austria have been evaluated using parameter-free tests in line with VDI 3857, Part 2 (2014) and OMBs have been derived from these for standardised grass culture (active biomonitoring) and for meadow grass surface growth (passive biomonitoring) - the calculation being based on the equation: OmB = 75th percentile + 1.5th interquartile range). For tree leaves (passive biomonitoring) the rounded 95% percentile* is stated as the OMB because of influences partly due to the specific type of tree.
