Problems solved by technology

So the problem is that the effort and cost will be huge
[0007] However, while the proposed system lists odors and chemicals as environmental data, the publication does not specifically address the detection of soil pollutants

Embodiment Construction

[0065] Embodiments of the present invention will be described below with reference to the drawings.

[0066] Figure 1 to Figure 3 A first embodiment of the present invention is shown.

[0067] refer to figure 1 , which shows the overall structure, multi-layer film sensors 10a, 10b... 10y (hereinafter, collectively referred to as 10) are provided on the ground level GL of the land G in the polluted area 4, the number of which corresponds to the number to be detected The number of pollutant types is used to analyze the smell S floating up from the ground level GL, and a plurality of sensors 10 are connected to a control mechanism 12 which will be described in detail later through a signal line L10. Here, a signal line L10 for communicating detection data transmitted by each sensor 10 is formed by bundling the signal lines La, Lb . . . Ly.

[0068] The sensor 10 can detect the presence or absence and also the concentration D of a pollutant.

[0069] When using the thin film ...

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...
