and the importance of the project

. There are currently promoting chemical-free vegetables produced, Wen Yong Li, avoiding using pesticides to get the best output quality. Consumer safety, as well as the environment in which the chemicals are harmful to producers and consumers. GPO-M Kit, or a combination of chemical screening in fruit, vegetables and cereals (2 groups) used to detect chemicals in vegetables and fruits and vegetables that are in there are levels of chemicals? Level 0-50%, 50-70%, more than 70%

the purpose of the experimental study on
1. To study and experiment to find the level of chemicals in fresh vegetables
2. To reduce the use of chemicals in vegetables GPO-M Kit or set of chemical screening in fruit, vegetables and cereals (2 groups) used to detect chemicals in vegetables and fruits and vegetables that are in there are levels of
3. So that students and people in the community have consumed fruits and vegetables that are safe from chemical experiments of sommutithan


. If we take the vegetables come to detect chemicals, so if you find that the purple stitches won't find chemical in vegetables that we bring.
