VOCkibocsátású

VOCkibocsátású is a Hungarian term used to describe substances, materials, or products that release volatile organic compounds (VOCs) into the air. VOCs are organic chemicals with relatively low boiling points that readily evaporate at room temperature. The term is often written as VOC-kibocsátású to emphasize the property of emitting VOCs.

VOCs originate from a wide range of sources, including solvents, paints, varnishes, coatings, adhesives, cleaning agents, building materials, and many consumer products. They can contribute to outdoor air pollution by forming ground-level ozone and secondary organic aerosols, and some VOCs are toxic or odorous. Indoor sources are particularly important, as enclosed spaces can lead to higher concentrations and greater exposure for occupants.

Health and environmental effects vary by compound and exposure level. Short-term effects may include eye, nose, and throat irritation, headaches, and dizziness. Long-term exposure and high concentrations have been linked to respiratory effects and, in some cases, more serious health outcomes. Indoor environments, such as homes and workplaces, often focus on reducing VOC exposure due to higher occupant time and closer proximity to sources.

Regulation and mitigation: VOC content is regulated in many regions, including the European Union, through directives that set maximum VOC content for solvents, paints, coatings, and some consumer products. Measurements are expressed in mg/m3 for air concentrations and in mass fractions for products. Mitigation measures include choosing low-VOC or VOC-free products, improving ventilation, and following proper storage and curing guidelines.
