In December, a widespread haze swept across central and eastern China, affecting numerous cities in the Yangtze River Delta and Pearl River Delta. Air quality in southern Hebei, most of Shandong, parts of Jiangsu, and northern Zhejiang deteriorated significantly, reaching heavy to severe pollution levels. According to the Central Meteorological Observatory, 25 provinces experienced varying degrees of haze by 6 p.m. on the 4th. The worst conditions were reported in areas like Suzhou, with dense fog particularly impacting the southwest and the Jianghuai region. It is expected that these adverse weather conditions will persist through the 8th.
Experts explain that winter haze often results from surface radiative cooling, which causes moisture in the air to condense, forming radiation fog. While this type of fog does not directly harm human health, it can trap pollutants and lead to dangerous chemical reactions. For instance, sulfur dioxide may combine with fog to form sulfuric acid aerosols, which are far more toxic than their original components. Additionally, temperature inversion layers often occur during heavy fog, preventing pollutants from dispersing and worsening air quality.
To protect yourself from the effects of haze, it’s important to avoid unnecessary travel and take precautions when driving. Visibility is greatly reduced, so drivers should slow down, use fog lights instead of high beams, and maintain a safe distance from other vehicles. If visibility drops below 10 meters, it's best to pull over safely and wait. In case of an emergency, turn on your hazard lights and place a warning triangle at a safe distance.
When passing through toll stations or service areas, be extra cautious, as traffic congestion and poor visibility increase the risk of accidents. Before heading out, check the weather forecast and plan your route accordingly. Also, ensure your vehicle is in good condition and carry essential supplies in case of unexpected delays.
Wearing a mask is a common practice during haze, but not all masks offer equal protection. Masks with activated carbon filters are more effective at blocking PM2.5 particles compared to gauze masks. N95 masks provide excellent protection but should be used once and discarded to prevent bacterial growth. Reusing them can lead to secondary contamination.
To protect your lungs, stay hydrated, eat a balanced diet rich in fruits and vegetables, and engage in regular aerobic exercise. Early detection through routine lung screenings is also crucial, especially for those over 40. Environmental responsibility starts with individuals—by making small changes in daily habits, we can contribute to cleaner air and a healthier planet. Together, we can make a difference.
