Problems solved by technology

However, due to the irregularity and specificity of the marker reaction, it is difficult or possible to use the effect concentration for the evaluation of the combined effect of combined pollution, making it difficult for multi-level biomarkers to be applied to the quantitative assessment of the combined effect of combined pollution

Embodiment 1

[0037] Such as figure 1 As shown, a soil microcosm experimental device for evaluating the joint effect of soil compound pollution, including: an experimental chamber 1 for filling the soil to be evaluated, an environmental simulation component 2 for simulating the soil environment and monitoring the soil environment, and It is equipped with the base 3 of the experimental chamber 1 and the environment simulation component 2 and the control board 4 for the adjustment and switching of the experimental chamber 1;

[0038] Such as figure 2 As shown, the experimental chamber body 1 is composed of forty-eight groups of modular chambers 11 and drive assemblies to form a regular cube structure. A driven block 13 arranged on the side and used to drive and rotate through the drive block 12;

[0039] Such as Figure 5 , 6 As shown, each module bin 11 of the experimental bin body 1 is made of transparent acrylic material, and multiple sets of partitions 113 are arranged at equal inter...

Embodiment 2

[0052] This embodiment is basically the same as Embodiment 1, the difference is that, as Figure 11 As shown, the first rotating block 121 on each side of the driving block 12 is driven to rotate through a linkage assembly, and the linkage assembly includes a motor rod 122 with double output shafts and four sets of driven bevel gears 123. The two sets of output shafts of the motor rod 123 are respectively connected to the first rotating block 121 on the upper and lower sides of the drive block 12, and the output shaft at one end of the motor rod 122 is provided with a main bevel gear 124 for driving each driven bevel gear 123 to rotate Each of the driven bevel gears 123 is connected to the first rotating block 121 on the corresponding side of the driving block 12 through a shaft; the rotation of the first rotating block 121 on each side of the driving block 12 can be realized by setting the motor rod 122 Since the transmission between the first rotating block 121 and the third...

Abstract

The invention discloses a soil microcosm experimental device for evaluating the combined effect of soil combined pollution. Comprising an experiment bin body used for filling to-be-evaluated soil, an environment simulation assembly used for simulating a soil environment and monitoring the soil environment, a base used for carrying the experiment bin body and the environment simulation assembly, and a control insertion plate used for adjusting and switching the experiment bin body. According to the soil microcosm experiment device, an indoor soil microcosm experiment can be effectively carried out so as to determine the ecological toxicity effect of single and combined pollution of soil on organisms, and the soil microcosm experiment device is convenient to sample, can quickly collect samples of required soil, and is high in practicability. Therefore, multi-layer biomarkers can be conveniently obtained to analyze the evaluation of the combined effect of the soil combined pollution on the soil.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a soil microcosm experimental device for evaluating the joint effect of soil compound pollution. Background technique [0002] The study of the joint effect of the soil complex pollution system can help researchers better understand the interaction between multiple pollutants coexisting in the soil, so as to better carry out soil pollution risk assessment and environmental management. Earthworms are widely distributed in soil and are good soil biological indicators and model organisms. The ecological effect assessment of soil pollution based on earthworm ecotoxicity experiments has become an important means of soil ecological risk assessment and environmental management. At present, the joint effect of combined soil pollution is mainly based on the earthworm individual level toxicological tests to obtain the half-effect concentration (EC50) and half-lethal concentration (...
