What are Volatile organic compounds?
VOCs are a class of chemicals that can have both immediate and long-term health effects. Indoor VOC concentrations are consistently higher (up to ten times higher) than outside values.
Many VOCs are man-made substances that are utilised and created in the production of paints, medicines, and refrigerants, among other things. VOCs include industrial solvents like trichloroethylene, fuel oxygenates like methyl tert-butyl ether (MTBE), and chlorination by-products like chloroform. VOCs can be found in petroleum fuels, hydraulic fluids, paint thinners, and dry cleaning chemicals. VOCs are typical pollutants found in groundwater. Certain solids or liquids emit volatile organic compounds (VOCs) as gases. VOCs are a class of chemicals that can have both immediate and long-term health effects.
VOCs are released by a wide range of products, numbering in the thousands. Organic compounds are commonly employed in household products as ingredients. Organic solvents are found in paints, varnishes, and wax, as well as numerous cleaning, disinfecting, cosmetic, degreasing, and hobby items. Organic compounds are used to make fuels. All of these items can leak organic molecules when in use and, to a lesser extent, while being stored.
Sources of VOC
-Solvents, paints, and paint strippers
-Preservatives for wood
-Sprays with aerosols
-Disinfectants and cleaners
-Air fresheners and moth repellents
-Automobile parts and fuels that have been stored
-Apparels that has been dry cleaned
Impacts of VOCs
VOCs are essential in the formation of ground-level ozone. Ozone from the ground can irritate the eyes, nose, and throat, as well as aggravate asthma and other lung disorders like bronchitis. When people with heart or lung disease are exposed to high amounts of ground-level ozone, they are more likely to die prematurely. Children, whose lungs are still developing and many of whom spend a lot of time outside, are especially vulnerable to high ozone levels.
VOCs can irritate the eyes, nose, and throat, as well as induce headaches and lack of coordination, nausea, and damage to the liver, kidneys, and central nervous system
Environmental Impacts of VOC
VOCs combine with nitrogen oxides (NOx) and carbon monoxide (CO) to generate tropospheric ozone (O3), often known as ground-level smog, when exposed to sunlight. The stratosphere's naturally occurring ozone shields the globe from the sun's harmful ultraviolet (UV) radiation. These chemicals, on the other hand, can encourage plant diseases, restrict seed formation, and obstruct fertilisation if generated at ground level. Heatwaves and hot climates can intensify photochemical processes, resulting in an increase in low-level ozone generation.
Global Warming - Methane, the second most common greenhouse gas emitted, is frequently released in tandem with VOCs. Greenhouse gases are chemicals that trap heat in the atmosphere, causing global temperatures to rise.
Acid rain - Acid rain occurs when the amount of acidic substances in the atmosphere increases. Water's pH can be raised to 4.2 or 4.4 when it combines with nitrogen oxides (NOX) and sulphur dioxide (SO2). Acidic precipitation is subsequently dispersed across natural habitats, urban landscapes, and oceans, raising the pH of vulnerable ecosystems. Fish are often unable to thrive in highly acidic environments, which can have a negative impact on the food chain as a whole. Essential nutrients can be washed away from forest floors by abrasive acidic substances, and aluminium deposits can contaminate nearby plants.
When dangerous chemicals vaporise and form poisonous gases, volatile organic compounds (VOCs) are formed. Every year, natural disasters such as wildfires emit enormous amounts of VOCs. Industrial operations and other man-made processes, on the other hand, account for a large portion of the planet's overall VOC emissions. When VOCs are exposed to sunshine, photochemical reactions occur in the atmosphere. These reactions can destabilise ecosystems and have debilitating effects on both individuals and the environment, depending on the amount and kind of VOCs emitted.
