Abstract.In the current environment, the world is changing and it seems that even more changes. Even greater impact on human consumption as food production.When producing a high yield. Technology was used. Inescapably Clear and obvious agricultural chemicals often have to use chemicals to get rid of Castro ice plant.Currently about pesticide residues in vegetables and fruits we consume, we have found that the chemical residues in four groups namely: 1.Organohalogens phosphate. 2 Carbamate Metz. 3 Pirates Android 4. Organohalogens Cl
in the experimental detection of chemicals in vegetables are three ways: 1., Sample preparation and extraction. two. evaporation and preparation. 3 color test
.Experimental results show the detection of chemicals in vegetables by color. Deep Purple were chemical. Level of less than 50% if it is a lilac chemical levels are 50 to 70%, but if the chemical is found in a gray level greater than 70%.First.Warm water mixed with baking powder 1 tablespoon per 20 liters of water will reduce the amount of toxins percent 90 - 95 2. Soaked vinegar 50%, 1 tablespoon per 20 liters of water for 15 minutes to reduce the amount of residue was 60 percent. - 84 3.Immersion in potassium permanganate crystals 20-30 in 4 liters of water will reduce the percentage of residues 35-43

. In the current state that the world is changing, and it seems that changes how much higher, resulting in a more human-only, regardless of whether it is food. Consumed. Because when producing high-yielding technology of hope has been implemented as inevitable and obvious is the agricultural sector with chemicals, they often have to use chemicals. Get rid of the plant hole sot. At present, about chemical residues in fresh vegetables and fruits that we consume it, we have found that chemical residues on 4 large group is 1. Hotel Karlovy Vary hotel check 2 phosphate 3. BA retroi membranes. 4 met. organochloride
. In an experiment to detect chemicals in fresh vegetables has 3 methods: 1. preparing the sample and the extraction of the substance 2. evaporation and color test preparation 3.
. Results of experiments to detect chemicals in vegetable output by matching colors. Dark purple chemicals are found in less than 50% if there are light purple chemicals on 50-70%, but if it is found that the chemical is found in gray levels greater than 70%. 1. Soak in cold water mixed 1 tbsp water per foo powder 20 litre can help reduce the amount of toxic residues are 90 per cent – 95 2. CR-50% vinegar per 20 litres of water 1 tbsp 15 long minutes reduce the amount of toxic residues has 60 per cent – 84 3. Alkaline potassium permanganate soak 20-30 pellets in water 4 liters will help reduce the amount of toxic residues per cent. 35-43

intro

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 that is the.

ExcerptsThe current state of the world is changing and it seems that no matter how much more changes result in more human more only, not to be a food consumption of productionbecause, when I hope to produce a high output technology, are used as inevitable. A clear and obviously, agricultural chemicals, often with the use of chemical disposal plant holes.Current chemical residues in fresh vegetables and fruits that we eat. We have found that a chemical residues in 4 large group is 1.organizer, oregano phosphate 2. คาร์บาเมต 3. A rating as it was popularly 4. Organochlorines
in the experiments detect chemicals in fresh vegetables in 3 ways: 1. The preparation of samples, and the juice 2.The volatile substances and prepare for 3. The test color
The trial detect chemicals in vegetables and displayed by the relative color dark purple found that there is a chemical in less than 50% if you find a light purple in color. There will be a chemical in 50 - 70% but if you find that it is a gray chemicals can be found in a level that is greater than 70 %.1.frozen hot water with baking powder 1 tablespoon per 20 liters water will help reduce the amount of pesticide residues are 90 per cent - 95 2. Soak vinegar, 1 tablespoon of 50% per 20 liters water for 15 minutes. Reduce the amount of pesticide residues 60 per cent - 84 3.The frozen pomegranate spotted in 20 - 30 scales in 4 liter water will help reduce the amount of pesticide residues are 35 per cent - 43

Introduction chapter 1

and the importance of a framework

At present, there are encouraged to produce organic vegetables, a sedan chair, use toxic chemicals get out to have a good quality and safe products to consumers, and protect the environment, chemicals are harmful to producers and consumersGPO - M Kit or check screening chemicals in fruits and vegetables and whole grains (2 groups) to use to detect chemicals in vegetables, fruits, in a level that is how many chemicals level 0 - 50 %,50 - 70 %, more than 70%


the purpose of the Study Trial 1. to study and try to find a level of chemicals in fresh vegetables
2.To reduce the use of chemicals in fresh vegetables GPO - M Kit or the screening filter chemicals in fruits and vegetables and whole grains (2 groups) to use to detect chemicals in vegetables and fruits that are in a level that is
3.To provide students and the people in the communities have consumed vegetables safe from chemicals


assumption of the experiment if we bring vegetables, and detect chemicals, so if you find that the
