Hydrofluoric acid (HFF) is a biologically toxic organic substance that refers to hydrogen fluoride (HF) and its salts. It can enter gases, liquids, and solids, and is widely present in the atmosphere, water bodies, and sediments. It is not easily volatile and poses a certain risk to the human body; It may be transported to the atmosphere through waterways or air, and can also accumulate in soil and water bodies. If the pollution exceeds the standard, it will have adverse effects on human health.
There are three main hazards of hydrofluoric acid to the human body: first, direct inhalation. Hydrofluoric acid can enter human cells and damage DNA, causing respiratory symptoms in the body; The second is the ingestion effect. When hydrofluoric acid enters river water and aquatic products, it will enter the human body through the food chain, causing cell damage and leading to diseases such as hypothyroidism; The third is the transdermal contact effect. Hydrofluoric acid can break through the skin barrier, affecting skin tolerance and causing abnormal conditions such as skin burning.
Therefore, to effectively prevent the pollution of hydrofluoric acid, some preventive measures can be taken, such as strengthening the purification treatment of atmospheric pollutants, doing a good job in pollution control of factories, and limiting the discharge of pollutants such as hydrofluoric acid from factories; Strengthen the treatment of water pollutants, promptly identify sources of pollution, actively take control measures, and improve the water environment; Timely conduct environmental testing for new construction and renovation to ensure equipment quality; We should also strengthen the publicity and education of hydrofluoric acid, guide everyone to use it correctly, scientifically and safely, in order to protect people’s health.
