Description

Apparatus for implementing hydrotoxicological tests
This invention relates to an apparatus for implementing hydrotoxicological tests, having a chamber gas-tightly separated from the environment containing a test tank for storing liquid, and a closeable opening enabling insertion and removal of the tank in and from the chamber and giving access to the tank placed in the chamber.
Nowadays, the effects of different compounds, mainly medicinal substances, fertilizers, pesticides and pollutants entered the environment, are examined by hydrotoxicological tests (replacing mammal laboratory tests) which are eligible for the relevant detection of the effects of low dose pollutants. The tests are performed in glass tanks at laboratory circumstances. Biologically well-known fish species with beneficial characteristics (with regard to tests) are placed in the tanks, mainly zebrafish (Danio rerio), medaka (Oryzias latipes), guppy (Poecilia reticulata), green swordtail (Xiphophorus helleri) and other fish species used in toxicity tests. Mostly the first two fish species have significance in researches regarding to their transparent embryos so the effect of toxic compounds to the ontogeny is readily observable even by examining transgenic lines created by means of fluorescent proteins.
However, the glass tanks have many disadvantages. The adhesive which fixes the sides of the tanks can be dissolved by certain test substances, destroying the tank, in the one hand, and strongly influencing the results of the tests, in the other hand. The tank are cleanable cumbersomely, there is no way for autoclaving owing to adhesives and the size of the tank, and it is not an inconsiderable backward that the glass tanks are fragile, heavy and accident- prone and the growth of algae can be started during long-term testing. Another disadvantage is that only one substance can be tested in the same atmosphere, because testing with different substances in the same atmosphere can affect results owing to the evaporation of substances from tanks to the environment and redissolving thereof. In the practice it means that one laboratory space is available to perform only one test which significantly increases the costs. However, the main disadvantage is that the testing staff can inhale vaporized toxic substances.
These backwards have been intended to eliminate by applying compartments, as disclosed by published patent document US 5730765 (A). In the compartment described in this document, a separate implementation of the tests can be achieved , thus in the same laboratory space more compartment can be placed. In turn the application of the apparatus highly increases the costs of the tests because all of the tanks should be placed in a separate apparatus.
Therefore, the object of the present invention is to provide an apparatus for performing hydro-toxicological tests, which does not contains materials that affect the results of tests (e.g. adhesive), but easily cleanable, and not fragile and accident-prone in the same time, and does not cause a growing of algae during long-term testing, and enables several substances to be tested in the same laboratory space without bearing any influence on the results.
Another object is to prevent the inhalation of the vaporizing, toxic substances by the testing staff during the performance of the tests.
Above objects have been achieved by providing an apparatus - for implementing hydrotoxicological tests, having a chamber gas-tightly separated from the environment containing a test tank for storing liquid, and a closeable opening enabling insertion and removal of the tank in and from the chamber and giving access to the tank placed in the chamber, and the apparatus is provided by at least two chambers separated from each other by means of gas-tight plates and each chamber is suitable to receive several tanks; said chamber consists of two gas tight sides, a front side, a backside each fixed to a framework of the apparatus, and the apparatus has a gas tight top part and a bottom part; and the front side of the chamber consists of an openable, gas-tight plate, and ventilators are inserted in the openings formed in said sides; and the tank is formed as a single unit and closed by a removable cover provided by air vents (14, 15). The chambers (2) are arranged above each other.
Said openable plate of the front side is hinged to the framework at the lower side of the chamber. Ann edge of the air vent is arranged above the cover.
Air conduit is applied to each chamber. The cover is provided by a control opening and a further opening enabling access of the air conduit to the tank.
The invention will be disclosed in details referring to the following drawings as attached. In the drawings:
Figure 1 shows a perspective view of a preferred embodiment of the multi-chambered, air-vented apparatus for implementing hydrotoxicological tests according to the invention,
Figure 2 shows a preferred embodiment of the tank, and
Figure 3 shows a further preferred embodiment of the tank.
In Fig. 1 a perspective view of the apparatus 1 for implementing hydrotoxicological tests according to the invention is shown. The apparatus 1 is a multi-chambered, air-vented apparatus 1 suitable for implementing hydro- toxicity tests, which contains e.g. five vertically arranged levels 2a with one chamber 2 on each level 2a, which have the same design in this embodiment. Certainly, the number of levels 2a is not limited to the number of levels 2a shown in this embodiment, it can be more or less. In each chamber 2 there are 3 tanks in lines, each made of a single piece - practically from plastic - which are eligible for liquid storage and closed by removable covers 13. The chambers 2 are separated from each other by gas tight plates (5) provided with at least two stabilizer members 4, supporting the weight of the tanks 3 filled with liquid for each chamber 2 in the vertically arranged embodiment as shown in Figure 1 , although any other equivalently strong and gas tight element can be applied. The sides 6 of the chambers 2 are closed preferably by transparent plates, which are fixed to the framework la of the apparatus 1. The front face 7 of the chambers 2 are closed advantageously by transparent openable plates 8 giving access to the tanks 3 and practically attached by a joint to the framework laapparatusof the apparatus 1 at the bottom of the chamber 2 and engaging the framework la of the apparatus 1 by gas tight gaskets (not shown in the figure). The plate 8 can be provided preferably with a lock, a handle and a spring operated stay piece. The backside 9, top 10 and bottom 10a parts of the apparatus 1 also consist of gas tight panels. In the apparatus 1 formed in such a way - by the closed position of the plates 8 - that each chamber 2 is hermetically separated from each other and from the environment. The apparatus 1 is provided advantageously by an air conduit 18.
Figure 1 shows that the sides 6 of each chamber 2 of the apparatus 1 consist of openings 1 1 which contain ventilators 12. There are similar openings 1 1 at the opposite sides 6 as well, where ventilators 12 are fitted, too. The ventilators 12 on the sides 6 ensure ventilation in such a way that while the ventilators 12 on the sides 6 pull air from the environment into the inner space of the chamber 2 the ventilators 12 on the opposite sides 6 draw the air from the inner space of the chamber 2 and lead it outside the room accommodating the apparatus 1 , through e.g. a central exhaust pipe, combined e.g. by a gas scrubber device. In this way, toxic substances cannot be breathed by the staff working in the testing room. Whereas each chamber 2 is hermetically separated from each other and the air is flowing one-way in each chamber 2, each chamber 2 can be manageable separately from each other, thus redissolving of gases vaporized from the tanks 3 in a chamber 2 into another tank 3 can be eliminated. Consequently, hydro-toxicity tests of different substances by different chambers 2 can be implemented without the risk of occurring interfering effects among tests performed simultaneously.
Figure 2 shows a preferred embodiment of a tank 3. In this embodiment the tank 3 has a form of a cuboid and provided by a removable cover 13 to permit cleaning. Since the adequate dissolved oxygen concentration of test solution poured in tanks 3 has an important role (min. 80% ASV), blow-holes 14,15 can be seen on the cover 13 of tanks 3 in Figure 2. The blow-hole 15 has edges 15 arising above the cover 13, while the other blow hole 14 does not have such an edge 15 a. A tank 3 is arranged in a chamber 2 in such a way that the air flow created by ventilators 12 streams in a direction from the blow-holes 14 to the other blow-hole 15. Since the air should take longer way around and above the edge 15a of the blow-hole 15, the pressure above the edge 15a of the blowhole 15 is slightly less than above the other blow-hole 14, thus the sucking effect occurring at the edge 15a blows out the air from the tank 3 while the air flows into the tank 3 through blow-hole 14. In such a way, fresh air could flow continuously above the liquid in the tanks 3 and oxygen can dissolved to the liquid if the partial pressure of dissolved oxygen in the liquid is decreased. The change of air is adequate in case of the same construction of blow-holes 14, 15 but the edge 15a increases practically the amount of air flowing through the tanks 3. The arrows having different width on Figure 2 show the direction of air flow. Further, a controlling opening 16 may be established at the cover 13 of the tank 3 e.g. for sampling. Algae do not appear during even long-term tests in the tanks 3 and the adequate oxygen concentration of test solutions is simply sustainable.
In the case of water samples intended for ecotoxicology, the adequate oxygen concentration is frequently sustainable only by atomization of the air in the tank 3. In this case a further preferred embodiment of the tank 3 shown in Fig. 3 is to be applied having further opening 17 at the cover 13 of the tank 3. An air conduit 18 can be led through the opening 17 beneath the liquid level in the tank 3, with a porous atomizer 19 made of stone arranged on the end of the conduit 18. The adequate oxygen concentrations of test solutions are not only sustainable by this solution but it is much more controllable. As regards the prior art solutions the advantages of the multi-chambered, air-vented apparatus 1 according to the invention involve space saving and enabling different substances to be tested in the same laboratory room without bearing any influence on the results of other tests. Moreover, the tanks 3 arranged in the apparatus 1 do not contain materials that affect the results of tests (e.g. adhesive joints), but easily cleanable, not fragile and accident-prone, and do not cause a growing of algae during even long-term testing, and the adequate oxygen concentration of test solutions is simply sustainable and much more controllable. A further important advantage is that toxic compounds do not enter the air during the tests, thus these are not breathed by the staff performing the tests.
