Random DENSITY units Find My Location: IP address, city, latitude & longitude. Here is a common chart of TVOC levels expressed as milligrams per cubic meter (mg/m3) and also micrograms per cube meter (ug/m3): Basically, in order to be safe you want the TVOC to be below 0.3 mg/m3 or 300 ug/m3. VOCs for a long-term exposure in large doses can damage liver, nervous system and kidneys. Some VOCs (as toluene) cause irritation at normal levels, eg allergic skin reactions, Bad odor and stale air are uncomfortable and affect peoples feeling of cleanliness, Some VOCs as formaldehyde can cause cancer. Hi Sir: BVOC is same as TVOC, when BME680 is used to measure indoor air qualilty, it is BVOC; when BME680 is used to TVOC can be measured in micrograms per cubic meter (g/m3) of air, milligrams per cubic meter (mg/m3), parts per million (ppm) or parts per billion (ppb).
