Abstract

This invention provides soil contamination detector and detection method that can significantly simplify investigation and analysis of a contaminant without use of any large analyzer like a gas chromatograph. The soil contamination detector comprises a sensor (10) and a control mechanism (12). The sensor (10) is disposed in a region (4) as a contamination investigation object, for detecting odor (S) of a substance (M) contaminating soil (G). The control mechanism (12) compares the concentration (D) of the contaminant (M) detected by the sensor (10) with the tolerance limit concentration (Pd) of the contaminant (M) to determine the contamination.

Description

technical field

[0001] The present invention relates to soil pollution detectors and detection methods, and more particularly to devices and methods for detecting pollutants based on the odor of substances that contaminate the soil. Background technique

[0002] Soil contaminated by harmful substances may adversely affect the health of the inhabitants and is therefore not suitable as a place of residence nor suitable for keeping animals or growing plants. For the reasons described above, or due to various other factors, the fact that the soil is contaminated with harmful substances constitutes a factor (disadvantage factor) that lowers the incidental value as real estate.

[0003] So far, soil pollution surveys to investigate whether the soil contains such harmful substances have been carried out by drilling holes in the soil to be investigated, collecting sample blocks (lots) at various depths, and transporting the collected sample blocks to investigation institutions by ca...
