Description

  The present invention relates to a method for removing a bisphenol-related compound, and more particularly, to a method for removing a bisphenol-related compound utilizing the ability of plants to absorb and resolve bisphenol-related compounds.

  In recent years, reproductive disorders of wildlife are concerned that chemical substances released into the environment are involved, and interest in environmental hormones is increasing. Endocrine disruptors (exogenous endocrine disrupting chemicals) are endocrine disrupting chemicals that disrupt the endocrine system when they enter the body of the organism and have adverse effects on health and the ecosystem, such as reproductive disorders. There are concerns about adverse effects on

  Bisphenol A is a chemical substance that is eluted from polycarbonate plastics and epoxy resins, and is a chemical substance that is suspected as an environmental hormone because it exhibits estrogenic activity. In the environment, bisphenol A is present in a wide range of freshwater surface water and freshwater sediments at low concentrations (freshwater surface water: 1 μg / L, freshwater sediments: 1100 μg / kg-dry), so industrial recovery It is said that it is difficult to disassemble.

  Conventionally, activated carbon, synthetic polymer separation membranes, or resin-based adsorbents have been used to treat wastewater containing environmental hormones. However, these have the problem that new industrial waste is generated after use. It was. Further, as described above, it is not suitable for removing chemical substances existing over a wide range at a low concentration.

  On the other hand, in recent years, bioremediation (bioremediation) has attracted attention as a technology for removing harmful pollutants in the environment using living organisms and purifying the environment. In particular, a technique for purifying environmental pollution using plants is called phytoremediation.

As phytoremediation of environmental hormones, Non-Patent Document 1 reports the purification of bisphenol A using eucalyptus cultured cells. In this report, when bisphenol A was administered aseptically directly to cultured eucalyptus cells, eucalyptus cultured cells metabolized bisphenol A, and the estrogenic activity of the metabolite was reduced by 80% compared to the estrogenic activity of the original bisphenol A. It is shown.

  An embodiment of the present invention will be described as follows. Note that the present invention is not limited to this.

1. Method for removing bisphenol-related compounds and method for purifying water The method for removing bisphenol-related compounds according to the present invention (hereinafter referred to as “this removal method” as appropriate) and the method for purifying water according to the present invention (hereinafter referred to as “this” as appropriate) The purification method is described in the following.) Is a method in which the plant is made to absorb the bisphenol-related compound by supplying water containing the bisphenol-related compound to the growing gramineous plant and / or asteraceae plant. I just need it.

  The present inventors have found that rice (Poaceae) and borage (Podaceae) cultivated using water (culture solution) containing bisphenol A absorbs bisphenol A from the roots. Therefore, if a Gramineae plant and / or a Capaceae plant is used, the bisphenol related compound contained in water can be removed and the water contaminated with the bisphenol related compound can be purified.

  Examples of the bisphenol-related compounds include compounds such as 2,2-bis (4-hydroxyphenyl) propane (bisphenol A) and 1,1-bis (4-hydroxyphenyl) cyclohexane. However, it is not limited to these.

  The grass family is not particularly limited. Examples of gramineous plants that can be used in the present invention include rice, chikarashiba, shimasumenoyahi, American suzunohie, kishozusumenohie, kuyoyoshi, reed, tsuruyoshi, suzunokatabira, susuki, chigaya, inobie, hinokishiba, toshiba, gyosima, crow, etc. Can be mentioned. Of these, grasses that can be hydroponically cultivated are preferred.

  Rice is the main commodity crop in Japan and is usually cultivated in paddy fields. Therefore, this removal method aimed at removing bisphenol-related compounds contained in water and purifying water contaminated with bisphenol-related compounds.

  Also, the aceae plant is not particularly limited. Examples of the poaceae plant that can be used in the present invention include Japanese knotweed, Japanese knotweed, ontade, buckwheat, sorrel, squirrel, swordfish, and rhubarb. Among these, a laceaceae plant that can be hydroponically cultivated is preferable.

  Since borage is a plant that grows naturally in fallow fields, riverbeds, and the like where contamination with bisphenol-related compounds exists, it is one of the most important plants of the family Taceae that are used in this removal method and this purification method.

  A growing plant means a plant that is currently growing. More specifically, it refers to a plant at a time when roots can absorb moisture and the like after rooting. If it is a grass family plant or a teraceae plant of such a period, it can always be used. The present inventors have confirmed the ability to remove bisphenol A using rice 2 weeks after sowing and scallop 4 weeks after sowing, and at least if it is a plant after this period, bisphenol-related compounds are added. It is possible to remove.

  In the present removal method and this purification method, water containing a bisphenol-related compound is given to the growing gramineous plant and / or teraceae plant as the roots of the gramineous plant and / or ericaceae plant. The water absorbed from the water is water containing a bisphenol-related compound. Therefore, the present removal method and the present purification method can be carried out by cultivating the above gramineous plant and / or the teraceae plant in soil containing water contaminated with bisphenol-related compounds.

  Alternatively, the removal method and the purification method can also be carried out by introducing water such as rivers and lakes contaminated with bisphenol-related compounds into the soil where the grasses and / or pods are grown. .

  More preferably, it is hydroponically cultivating the above gramineous plant or teraceae plant using water containing a bisphenol-related compound. Here, hydroponics means cultivating the plant roots in direct contact with water. That is, plants absorb and grow water that is in direct contact with roots, not water contained in the soil. Therefore, this removal method and this purification method can be implemented by hydroponically cultivating water such as rivers and lakes contaminated with bisphenol-related compounds. Hydroponics may be carried out by floating a hydroponic cultivation apparatus or the like on the surface of the river or lake, or by introducing water from the river or lake into a hydroponic cultivation facility or the like.

  Furthermore, the present inventors have confirmed that the bisphenol A absorbed by the above gramineous plant or teraceae plant does not accumulate in the plant body. Therefore, it is not necessary to treat a plant body that has been cultivated using water containing a bisphenol-related compound and has absorbed the bisphenol-related compound as new contaminated waste. In addition, even when a commercial crop such as rice is used, since the bisphenol-related compounds are not accumulated in seeds harvested from the plant, the commercial value does not decrease.

2. Method for Producing Bisphenol Affinity Compound-Removed Water The method for producing bisphenol-related compound-removed water according to the present invention (hereinafter referred to as “the present production method” as appropriate) is applied to growing gramineous plants and / or teraceae plants. On the other hand, as long as it contains water containing a bisphenol-related compound, the bisphenol-related compound removing step for absorbing the bisphenol-related compound into the plant and a recovery step for collecting the water given to the plant may be used. .

  Among the above steps, the bisphenol-related compound removal step is the same as the above-described “1. Method for removing bisphenol-related compound, method for water purification”, and redundant description is omitted here.

  In the bisphenol-related compound removal step of this production method, it is preferable to hydroponically cultivate the grass family and / or the asteraceae plant using water containing the bisphenol-related compound.

  In the step of removing bisphenol-related compounds, cultivating gramineous plants and / or teraceae plants in soil containing water contaminated with bisphenol-related compounds, and water contaminated with bisphenol-related compounds with gramineous plants and / or Although it is possible to introduce it into the soil in which the plantaceae is cultivated, in this case, it is difficult to recover water easily in the recovery step, and a complicated operation is required to recover the water. Therefore, in order to collect water easily in the collection step, it is preferable to hydroponic the plant.

  Hydroponics can be performed directly on the surface of rivers and lakes contaminated with bisphenol-related compounds as described above, but there is a possibility that new contaminated water will flow in during the bisphenol-related compound removal process. There is. Therefore, it is preferable to perform hydroponics, for example using the water tank etc. which introduce | transduced the water contaminated with the bisphenol analog, etc. on the conditions with low possibility that a new pollution will arise.

  In the recovery step of this production method, the method for recovering the bisphenol-related compound removed water is not particularly limited. For example, when hydroponics is performed using a water tank or the like, bisphenol-related compound-removed water can be recovered by removing plants and hydroponic cultivation devices from the water tank. It is also possible to transfer the bisphenol-related compound-removed water to another water tank or the like using a pump or the like.

  The bisphenol-related compound-removed water is not particularly limited as long as the bisphenol-related compound originally contained in the water used as the raw material is reduced to the target amount, and the bisphenol-related compound content is required to be zero. It is not a thing. Therefore, what is necessary is just to measure the quantity of the bisphenol related compound contained in water suitably in a bisphenol related compound removal process.

  The use of the bisphenol-related compound removal water obtained by this production method is not particularly limited.

[Example 1]
Rice or borage seeds were sterilized with 2.5% sodium hypochlorite solution, then rinsed with sterile water and placed at 4 ° C. overnight in sterile water. Seeds were sown in MS medium containing 1% sucrose and 0.3% gellan gum, and cultured at 25 ° C. under conditions of 16 hours light period / 8 hours dark period for 2 weeks for rice and 4 weeks for borage.

  Two weeks of rice or four weeks of borage plants were transplanted one by one into a 5 mL 0.01% hyponex solution (hereinafter referred to as “culture solution”) containing 1000 mg / kg fresh weight bisphenol A. The culture was continued for 15 to 21 days, and the bisphenol A content in the culture solution was measured by HPLC every 3 days. In addition, during that period, the amount of bisphenol A contained in the plants of rice and borage was measured by HPLC every week.

  The bisphenol A content in the culture was analyzed by subjecting the culture solution directly to HPLC.

  A sample for analysis of bisphenol A in a plant was prepared as follows. That is, 100 mg fresh rice or 200 mg fresh rice was frozen in liquid nitrogen and then crushed in a mortar. This was transferred to a 2 mL Eppendorf tube and 200 μL of methanol was added. After standing for 20 minutes, the mixture was centrifuged (15000 rpm, 5 min), and the supernatant was used as a sample for HPLC analysis.

The HPLC separation and detection conditions are as follows.
Waters 2690 HPLC system column: X-Terra MS C18
Sample volume: 10μL
Separation liquid: 35% acetonitrile flow rate: 1 mL / min (constant)
4-isopropyl phenol (4-IP) was added as an internal standard at a concentration of 200 μM.
Detects bisphenol A and 4-IP at 277nm absorbance
Measurement for 15 minutes The change in bisphenol A content in the culture solution is shown in FIG. As is apparent from FIG. 5, the bisphenol A content in the culture broth gradually decreased after the start of culture in both rice and borage. In rice, the bisphenol content in the culture decreased to 10% 21 days after the start of the culture. Moreover, in the borage, the bisphenol content in the culture broth became almost 0 15 days after the start of the culture.

  FIG. 6 shows the measurement results of bisphenol A in rice 7 days, 14 days and 21 days after the start of culture. FIG. 7 shows the measurement results of bisphenol A in the borage 7 days and 14 days after the start of culture. FIG. 6 and FIG. 7 both show the peak portion of the HPLC chart. As is clear from FIG. 6, bisphenol A in rice decreased with time, and was hardly detected 21 days after the start of culture. Further, as is apparent from FIG. 7, bisphenol A in the borage was hardly detected 14 days after the start of the culture.

  From the above results, it was suggested that rice and borage absorb bisphenol A in the culture broth from the roots and decompose rapidly.

[Example 2]
5 mL of a 0.01% hypoponex solution (culture medium) containing 500, 1000, 2000 mg / kg fresh weight bisphenol A added to the plant of the second week rice or the fourth week rice plant cultured in the same manner as in Example 1 above. ) Were transplanted one by one. The culture was continued for 21 days, and the bisphenol A content in the culture was measured on the 21st day by HPLC. The amount of bisphenol A in the culture broth was regarded as the amount of bisphenol A absorbed by the plant.

  The rice results are shown in FIG. Moreover, the result of the squeeze is shown in FIG. As is apparent from FIGS. 8 and 9, when the amount of bisphenol A in the culture medium increases, the amount of bisphenol A absorbed by rice and swordfish also increases, and both are in a linear positive correlation. It became clear.

Example 3
Absorption experiment was carried out for 15 days by transplanting 10 g of fresh rice or scallop to 1 L of 0.01% hypoponex solution (culture solution) containing 1 μg / L bisphenol A corresponding to the concentration of bisphenol A in the environment. After 15 days, liquid-liquid extraction was performed using 100 mL of dichloromethane per 1 L of the culture solution. After collecting the dichloromethane layer, it was dried using an evaporator, and the residue was dissolved in 200 μL of sterile water to obtain a sample for analysis.

  The results are shown in FIG. As is clear from FIG. 10, the peak of bisphenol A was detected from the control (the culture solution not cultivating the plant), but from the culture solution cultivated rice and the culture solution cultivated borage, No peak was detected.

  From the above results, it was suggested that if bisphenol A is contained to the extent that it is contained in the contaminated water in the environment, rice or scallop can be absorbed and decomposed almost completely.

  The present invention can be used in public works, environmental industries, agriculture, horticulture industries, and the like.
