Abstract

The invention discloses a device for pipelined fish exposure test. The device comprises a medicine mixing portion, a conveying portion and a test portion; the medicine mixing portion at least comprises a medicine mixing box with liquid medicines inside; the conveying portion comprises a conveying pipe with a fixed end connected to the medicine mixing box; the test portion comprises a pressure box,a test box, a drainage box and a plurality of guide bodies, a free end of the conveying pipe faces the pressure box, and liquid medicines in the pressure box form laminar flow in the test box throughthe guide bodies. The device can be used for providing a stable environment for the test to obtain more reliable test data.

Description

technical field [0001] The invention relates to the field of fish bioaccumulation tests, in particular to a device for flowing water fish exposure tests. Background technique [0002] In the chemical bioaccumulation flow-type fish test, it is necessary to test the impact of the relevant chemical substances on the fish bio-accumulation test, among them, the flow-type test is required for easily degradable and highly volatile chemical substances. During the process, the liquid medicine needs to be automatically and continuously entered into the fish tank, and the volume of the medicine in the fish tank needs to be kept relatively constant. [0003] In the prior art, the traditional Chinese medicine liquid is generally added to the fish tank without any treatment, resulting in uneven distribution of the medicine liquid, which cannot achieve the original intention of the test, and the stability of the test and the reliability of the test data are relatively poor. Therefore, a s...
