METHOD OF DETECTING POLLUTION OF SURFACE AIR USING ARTIFICIAL DEW Russian patent published in 2011 - IPC G01N1/00 

FIELD: chemistry.

SUBSTANCE: method of detecting pollution of surface air using artificial dew is carried out by detecting heavy metals in said dew, where the artificial dew is collected by condensing water vapour on a cooled sorption surface, which is extracted by creating a temperature gradient in the air boundary surface, and concentrating the water vapour, and the sorption substrate used is moulded thin-fibre plates with a microporous structure made from hydrophilic material. Cooling with a coolant and subsequent exposure of the moulded plates takes place in flat shallow cuvettes made from chemically inert material (plastic, carbon fibre-reinforced plastic, composite materials), the number and installation of which is determined by observation conditions within the territory.

EFFECT: invention enables more accurate and quality assessment of air pollution on a new technological level.
