What Is The Volatile Organic Compounds ?
14 November 2023What is the volatile organic compounds ?
The harm of VOCs mainly manifests in the following aspects:
VOCs can participate in photochemical reactions in the atmosphere, generating ozone and fine particulate matter (PM2.5), forming photochemical smog and haze, reducing air quality, affecting visibility, damaging plant growth, and increasing the risk of respiratory and cardiovascular diseases.
Some substances in VOCs have toxicity, irritation, sensitization, and carcinogenicity, such as benzene, toluene, xylene, formaldehyde, styrene, etc. Long term or high concentration exposure to these substances can cause varying degrees of harm to the human body, such as headache, eye irritation, throat discomfort, skin hypersensitivity, liver and kidney damage, neurological disorders, leukemia, etc.
Some substances in VOCs have strong odors, such as ethanol, acetone, butanone, etc., which can affect people's comfort and work efficiency, causing indoor air pollution and odor problems.
Some substances in VOCs have flammable and explosive properties, such as methane, ethane, propane, etc. Within a certain temperature and concentration range, when mixed with air and encountering open flames or sparks, they can cause explosions or fires, endangering personal and property safety.
In order to reduce the harm of VOCs, we can take the following measures:
Choose products with low or no VOC, such as water-based coatings, solvent-free adhesives, fragrance free cleaning agents, etc., and avoid using products containing high concentrations of VOCs, such as paint, gasoline, insecticides, etc.
Increase indoor ventilation by using natural ventilation or fresh air systems as much as possible to eliminate accumulated VOCs in the room and maintain air circulation and freshness.
Use air purifiers or plants to absorb or decompose VOCs in indoor air, improving indoor air quality. Air purifiers should choose products with efficient filter screens or activated carbon adsorption functions; Plants with strong anti pollution ability and purification effect should be selected, such as aloe, chlorophytum comosum, ivy, etc.
Regularly detect the VOCs content in indoor air, and promptly detect and handle abnormal situations. Professional testing instruments or service institutions can be used for testing; Some simple methods can also be used to determine whether indoor air is contaminated with VOCs, such as smelling odors, looking at colors, and observing body reactions.
Strengthen the formulation and implementation of laws, regulations, and standard specifications for VOCs, increase supervision and control of VOCs emission sources, promote the research and application of VOCs emission reduction technologies, improve the recovery and utilization rate of VOCs, and reduce the emission and harm level of VOCs.
