Biological measuring techniques for the determination and assessment of effects of air pollutants on plants (biomonitoring) - Method of the standardised grass exposure
Air pollution can cause accumulation of substances in plants. The assessment of such accumulation shows deposition-related inputs into ecosystems and may indicate risks for plants, animals and humans. In many cases, grass cultures (Lolium multiflorum) are used as plant accumulation indicators. The standard describes the range of use and practical steps of the method of the standardised grass exposure. The individual steps from cultivation, exposure, sampling and sample handling are presented. In addition, the standard user gets information and operational recommendations regarding quality assurance, performance characteristics, presentation of measured data and assessment.
