Impact of atmospheric particles in Romania
Atmospheric particulate matter can have a serous impact on both people and the environment. So-called aerosols, liquid or solid particles in a gas, not only adversely affect human health but can also play an important role in climate change. The various impacts are related to the size of particulates and their chemical composition. Microbes and viruses are able to cling to the particles and therefore damage human health and agricultural and natural systems. The EU-funded Icaarus project has made a detailed study of the chemical composition of atmospheric PM found in the densely populated Iasi region of northeastern Romania. Despite the existence of strict EU legislation governing atmospheric PMs, relevant information and monitoring data for Romania has been lacking to date. Therefore, researchers have conducted field measurements and laboratory analyses as part of an investigation into the quantity and distribution of both coarse and fine atmospheric particulates in the region. Analysis of the data has shown that the chemistry of PM sampled in northeastern Romania is highly complex and involves inter-particle interaction, particularly under favourable meteorological conditions. In addition, a clear distinction has been identified between fine particles that contain compounds produced by human activity and coarse particles that contain natural compounds. Data collated by the Icaarus project can be used to calculate pollution levels in the region and help to determine the possible risk to human health. Results and methodologies provided by the initiative can also act as a reference point for Eastern Europe, thereby enabling policymakers to take better informed decisions.
