Hello ladies and gentleman. For the latest article, I briefly wrote about the information in chemical substances. Today, I would like to introduce my project on chemical substances. As I wanted to know the harmfulness of it, I had an experiment for the last few months.

 
     The experiment consists of two parts. The first experiment is to determine the impact on the amount of chemicals, whereas the second experiment is to see the effect on the different types of chemical substances. In this article I would like to discuss the first experiment, which dealt with the effects on the amount of chemical substances.

     Since I wanted to know the effects of chemical, I used kind of an indirect way. I did the experiment with bean plants. For each plant, I watered attenuated artificial flavor enhancer(in Korean, Miwon) and watched the growth. The experiment was done in two parts. First, I grew the plants for one week and saw the growth roughly, and in the second experiment, I grew them for one month and measured status precisely.

     So the following is the procedure of this experiment. First, I germinated bean on the Styrofoam dish. Then, in four pots, I planted four beans each. And then, I prepared three one litter bottle. In each bottle, I dissolved 20g, 40g, 60g of artificial flavor enhancer. After the beans grew about 5cm, I watered those artificial flavor enhancer water for one week. So, the manipulated variable is the amount of artificial flavor enhancer dissolved in the water.

Below are some pictures of preparing the experiment

These are the pictures and results of the experiment.

     The green pot was watered 'water', pink pot is 20g, blue pot is 40g, and purple pot is 60g. As you can see, the result was just like what I expected. The growth difference was so huge. But the interesting part was that the purple pot beans were even rotten! It smelled stinking and was covered with mold. (picture below)

2nd week

3^rd week (Awwwww,,, the picture is not clear. Sorry)

 
4^th week
 

As you can see the growth is markedly different. And below is the data of the 4 criteria I measured.

 

 




     As you could see in the pictures and graph, beans which had water showed the best growth. Moreover, plants with low concentration grew better than the ones which higher concentration. This is a very acceptable result as we all assumed. The 40g and 60g plants dried easily and I think that this is because of osmosis phenomenon. The water in the plant seems to have been come out.



     We could re-verify how harmful artificial flavor enhancer is to plants. Well, since there will be numerous of other factors in the nature, I cannot just easily conclude the result. However, like what plants suffered from chemicals, I believe that nothing would be different for humans as well. The artificial flavor enhancer is thing that we can eat. However, the chemicals that are emitted to the nature is much more noxious than this artificial enhancer. I hope something must be done to reduce chemical usage for the environment.



     For the next article, I would introduce the second experiment based on the type of artificial chemicals. Thanks for reading!
