Hazardous waste (Hazardous waste) refers to the production, operation, scientific research and other activities in the production of waste containing hazardous substances or with dangerous characteristics. These wastes are hazardous and can have serious impacts on the environment, ecosystems, and human health. The hazardous characteristics of hazardous waste are mainly in the following aspects:
First, toxicity. Hazardous waste in many cases have toxicity, it will produce harm to the environment, damage to human health. Some hazardous wastes may not be toxic after dilution to a certain extent, but it still takes a long time and cost to completely eliminate toxicity. Some highly toxic hazardous wastes require more stringent measures.
Second, corrosivity. Corrosivity is the ability of hazardous waste to produce corrosive or destructive effects on objects that come into contact with it. Some acids and alkalis, chemicals and batteries are strongly corrosive. If these substances are not properly handled and disposed of, they can be extremely hazardous to groundwater, soil, buildings and equipment.
Again, flammability. If the hazardous waste is flammable, it will be very easy to cause fires and explosions, posing a great threat to people's lives and property. For example, in chemical plants, hazardous waste disposal sites and transportation process, encountered problems arising from flammable substances, once splashed to the fire source, will instantly form a fire mass, very easy to form a fire.
Finally, radioactivity. This is one of the most dangerous characteristics of hazardous waste. Some hazardous wastes are radioactive, such as radionuclides, radioactive medical equipment, etc. If proper treatment and disposal measures are not taken, they can pose a great threat to human beings, animals, plants, the environment and material property.
Consolidating the above, the hazardous characteristics of hazardous wastes are very complex, and different hazardous wastes have different hazardous characteristics. Therefore, when dealing with these wastes, it is necessary to fully understand these hazardous characteristics and take appropriate safety measures to prevent possible harm to the environment, ecosystems and human health.
