This PPM to mg/m3 conversion is based on the molecular weight of the PPM to M/MG3 converter For gases Carbon monoxide [CO], M = 28.01 g/mol.

The 11 C images and 13 C NMR spectra for 600‐ppm CO 2 labeling under high‐light and water stress show strong sugar and starch peaks but no peptide peak for the most photosynthetically active region of the leaf (Dirks et al., 2012, figure 7, upper right).

Although it is most (17) recently reported carbon monoxide peak concentrations of up to 60 mg/m3 ( 53 ppm) in homes with stoves operating on town gas. Environmental tobacco Levels of 600-800 ppm are typical in office environments. Guidelines suggest CO2 levels do not exceed 1000 ppm (700 ppm above outdoor levels), the 27 Jul 2016 Health effects of high indoor CO2 concentrations three short trials, they breathed air containing 600, 1,000 and 2,500 ppm of carbon dioxide. The typical average indoor CO2 concentration ranges from 800 to 1000 ppm ( NRC Twenty-two participants were exposed to CO2 at 600, 1000, and 2500 ppm Chữ "ppm" xuất phát từ tiếng Anh parts per million, có nghĩa là một phần triệu. Nó thường chỉ tỷ lệ của lượng một chất trong tổng số lượng của hỗn hợp chứa chất The CO2-Pro instrument measures the partial pressure of CO2 gas dissolved in water using infrared detection.

Discrimination decreased by ~2.5‰ from 400 to 600 ppm CO 2 , then increased ~1.4‰ from 600 to 800 ppm 3 Dec 2016 Offices often have CO2 levels of 600 ppm or higher. Only 5% of US offices have average CO2 concentrations above 1000 ppm [Persily 2008], 5 Jan 2021 Miller recommended trying to keep the CO2 levels in indoor spaces below 600 ppm to reduce the chances of coronavirus transmission.

Various international norms suggest 600 ppm as a maximum CO2 level for a very good air quality, 600 to 1000 ppm is considered good air quality and 1000-1400 ppm is regarded as acceptable (EN 13779, CDC, IDPH, IAQUK, OSHA, EngineeringToolBox).

Mild exposure over 2-3 hours (a CO level between 35 ppm and 200 ppm) will produce flu-like symptoms such as headaches, sore eyes and a runny nose. Medium exposure (a CO level between 200 ppm to 800 ppm) will produce dizziness, drowsiness and vomiting in as little as 1 hour.
