The Ministry of Environmental Protection is warning of severe air pollution throughout the country today, March 2, 2014, and tomorrow, due to dust and sand storms coming in from the Mediterranean Sea. As a result, there will be particularly high levels of particulate matter in the air. These are small particles that can get into the lungs and cause breathing difficulties. This situation can be especially hazardous for those with weak hearts, lung diseases, the elderly, children, and pregnant women. These populations should stay indoors as much as possible during this time.
