Air Quality - Biomonitoring network

To limit the impact of atmospheric pollution, it is important to assess its emissions and fallout. Living organisms such as mosses, kale and grasses are used to assess the impact of pollution in specific locations. Their characteristics make them particularly sensitive to the atmosphere around them. Subjected to excessive pollution, they react or are even likely to disappear in this environment, and can therefore be used as indicators of air quality. The specific bioindicators used in Luxembourg detect the presence of organic pollutants and heavy metals in the air by quantitative accumulation. These bioindicators, particularly leafy vegetables, trap these particles, which can only be partially eliminated by washing (rain, tap water before consumption).
