The increased air quality also supports the process of photosynthesis to successfully occur in plants, allowing them to regenerate and grow at a healthy rate. According to the EPA (Environmental Protection Facility), a solvent only qualifies if it meets the following criteria: As mentioned earlier, VOC is responsible for indirect ozone generation.
