Abstract
Description
The present invention relates to a bioaccumulation test apparatus, and more particularly, to a syringe pump operated by control of a controller and diluted water (water) whose flow rate is controlled as a flow meter and a flow rate control valve, It is possible to carry out a bioconcentration test by keeping the amount of dissolved oxygen and temperature required for maintaining the growth of the organisms constant, and to purify and discharge the effluent discharged through the test using activated carbon.
Due to the increase of harmful substances due to industrialization (eg, environmental hormone risk), damage to the ecosystem due to the increase of wastes or pesticides as water pollutants, severity of residual pesticides in food, and heavy pollution of heavy metals in soil The human body and the environment are threatened. It is very important and urgent to monitor the harmfulness caused by chemical substances that adversely affect the human body and the environment. Currently, more than 80,000 kinds of chemical substances are used commercially at home and abroad. Each year, thousands of new substances are used as raw materials for foods, medicines, cosmetics and medical equipment. How much do they affect the human body and the environment? Toxicity And exposure levels and the degree of accumulation of toxic substances in vivo upon exposure are very important.
As a field for securing the safety of such chemical substances, there is an environmental hazard evaluation. To this end, legally required environmental toxicity test items are known, and the above test items are classified into a risk of direct and indirect human and environmental organisms The possibility is tested and analyzed.
All the data related to the exposure dose, the decomposition rate, the concentration rate and the toxicity are analyzed and analyzed through the above-described environmental hazard evaluation, and the results are collected, so that a reasonable evaluation is made for one compound. .
A wide range of environmental monitoring methods are needed to diagnose and respond to such environmental hazards early, and toxicity is tested using recombinant microorganisms, luminescent bacteria or yeast, or using enzymes. They mainly measure harmfulness by optical methods.
In order to protect the ecosystem from the above chemical substances or environmental pollutants and to promote sustainable development, toxicological tests of aquatic organisms (fish, daphnia, etc.) and terrestrial organisms are carried out on industrial chemicals, pesticides, veterinary drugs and pharmaceuticals , And bioconcentration tests on aquatic organisms. All tests are conducted in accordance with the OECD Test Guidelines and test methods in the United States, Japan and Europe. The most important characteristic of the toxicity evaluation and bioconcentration test for aquatic organisms is that they have an indirect route of administration in which the test substance (test solution) is dissolved in water and moved into the organism.
However, the exposure method is an exponential method (Static test) in which the test solution is not exchanged during the test period, a semistatic test in which the test solution is changed in a predetermined period during the test period, a test solution is continuously exchanged (Flow-through test), it is important to select the most appropriate route of exposure for each substance. Such water-soluble formulas are produced manually by hand in order to maintain the concentration of the test substance when the test substance is not stable in the aqueous (water) state, so that the precision and the continuous supply are difficult.
In order to solve such a conventional problem, the prior art document 10-0906180 (the name of the invention: a test solution producing apparatus of the present invention) and the registered patent 10-0958859 (a water-type daphnia toxicity test apparatus) are provided. In this

Wherein the mixing and discharging device comprises: a lower pedestal having a circular seating groove formed at an upper portion thereof; A mixing water tank for mixing and diluting the diluted water (water) with the test solution by means of an agitating device, the mixed water being introduced into the circular recessed groove of the lower pedestal so as to prevent water leakage; A discharge port formed on both sides of the upper portion of the mixing water tank to communicate with each other at the same height so as to discharge mixed water to the outside; An overflow hose whose upper end is connected to the outlet and whose lower end is connected to a "Y" And a supply hose connected to an upper portion of the lower portion of the "Y" -shaped connector to supply mixed water to the test water tank, and is mounted on the vertical moving plate of the front and rear moving devices.
According to the present invention, the diluted water and the experimental material solution, which are maintained at a saturation concentration of 60% and a temperature of 20 to 25 ° C and maintained at a temperature within 2 ° C, are fed into the mixing water tank of the mixing apparatus, And the diluted mixed water is continuously supplied to the test water tank from the mixed water tank. By supplying the diluted mixed water to the test water tank while maintaining the set dilution ratio, it is suitable to keep the concentration of the specific chemical in the living water constant In addition, it was possible to prepare a test solution with a constant concentration by mixing the diluted water and the test substance solution in the first, second, and third levels. Also, the effluent water generated in the test water tank was supplied to the activated carbon, It is possible to prevent the environmental pollution by discharging the purified water through the cylinder.
