DEVICE FOR MONITORING INDUSTRIAL CONTAMINATION OF SOIL AND GROUND WATER Russian patent published in 2016 - IPC G01N33/24 

FIELD: ecology.

SUBSTANCE: invention relates to environmental protection, particularly to a device for sampling hazardous industrial contaminants, acting on soil. Device is a split plastic structure having two parts separated by a filtration partition. Upper part 1 has an open surface with a fixed area, in which is placed non-contaminated soil or light-filtering inert material 6, for example sand. Filtering partition enables to separate a liquid fraction from a solid fraction and consists of a perforated partition and filtering fabric 3. Lower part 2 is meant for collecting liquid fraction. Parts are connected by an easy to dismantle connector 4. Area of open surface of upper part 1 is 50-300 cm², height of upper part is 1 5-20 cm, height of lower part is 2 20-100 cm. Device is installed in recess in ground at a depth corresponding to height of upper and lower parts of assembly, with diameter corresponding to diameter of upper and lower parts.

EFFECT: more accurate estimation of anthropogenic impact of pollutants on soil.
