Atmospheric electricity as a proxy for air quality: relationship between potential gradient and pollutant gases in an urban environment... A formulation relating PG with TG concentrations allows the estimation of constants of proportionally between TG-PM to be ∼50 cm−3 ppb−1; which are similar to the values found in direct TG-PM measurements in UK cities, validating the present results
