Abstract
The invention discloses a biological atmospheric heavy metal pollution detection and judgment device and an application. The detection and judgment device comprises a pollution element adsorption plant living body unit, a humus unit, an element migration and pollution element chelating unit, an ion exchange unit and a judging unit which are sequentially arranged from top to bottom; the adsorptionplant living body unit is used for capturing and accumulating heavy metal pollution elements in the atmosphere; the element migration and pollution element chelating unit is matched with the ion exchange unit to realize transmission and migration of the heavy metal elements; and the judging unit is used for judging a pollution situation, so that the collection and detection of atmospheric heavy metals are completed, and the pollution condition is detected and judged. The device is buried in a test place or placed on the ground, and can be taken out after a plant living body adsorbed to the surface is withered and dead; and the pollution condition of the atmospheric heavy metals can be judged according to a color comparison table through a color development state of the lower judging unit.
Description
technical field [0001] The invention relates to the technical field of air pollution detection, and more specifically, to a biological type atmospheric heavy metal pollution detection and discrimination device and application. Background technique [0002] The carriers of toxic heavy metals entering the human body mainly include water, air and food. Among the three, especially the way of air inhalation and infiltration needs the most attention, and is often the most easily overlooked. On the one hand, air is the environmental medium most closely related to human activities on which human beings rely for survival, and it is ubiquitous and present at all times. On the other hand, China's atmospheric environmental protection standards related to heavy metals are relatively weak and lagging behind in the formulation of standards, lack of detection and control of atmospheric heavy metal pollution, and have not included heavy metals in ambient air and pollution source exhaust gas...
