Lidar differential method of sulphur-containing hydrocarbons ultra low concentrations detection

摘要

The detailed study of the influence degree of different pollutants on an environment requires differential pollution monitoring that nowadays becomes possible due to development of measuring instruments such as laser systems for remote sensing ~(1-6). Until recently pollution exhaust monitoring from petroleum sources was reduced to the hydrocarbons sum quantity. The hydrocarbons with the small contents of sulphur low permissible level (LPL) is equal to 5 mg/m~(3 7, 8). Such approach did not reflect the real situation, since the chemical composition of exhaust was not taken into account.
