Effect of Methyl Bromide Against Commodities


Some commodities are not suitable treated with methyl bromide. When there are concerns that the commodity will have bad influence of methyl bromide, and the owner of the commodity fumigation companies must seek advice of experts regarding the effect or entered into prior to the test commodity fumigation done before. Effect of methyl bromide on commodities vary, depending on the type of fumigated commodities, including:


1). Decreased ability to grow.
Methyl bromide fumigation on seedling plants can result in decreased power to grow. Tolerance of seedlings to methyl bromide each different from one other, but many are affected, although only a single fumigation at normal doses. When methyl bromide fumigation should be used for seed, use a lower dose (eg 10 g/m3).

2). Residue formation.
Methyl bromide reacts with-OH. -S-, and-NH in the commodities so that form the methylated compounds and inorganic bromide. Excessive levels of These two compounds can not be contained in foodstuffs. Fumigation of commodities with high doses or which may lead to less well the aeration excessive residues of the two compounds in foodstuffs.

3). Pollution / stain (taint).
Fumigation of commodities that absorb fumigant, such as flour, soy flour or nuts, especially at high doses, can result in sulfur stains seem obvious, especially at the time the product was processed. Bread made from flour that has been fumigated, cut and wrapped immediately after baking, probably will have a special smell. This odor arising from sulfides out methyl bromide due to reaction with the materials that contain sulfur.

A similar reaction can cause damage to other commodities such wool, which have been tanned leather, natural rubber and glass paper (Cellophane).

4). Changes in the quality process.
Fumigation with methyl bromide can alter the quality of the commodity fumigated, especially when used in excessive doses, but the data on this subject only there is little. Methyl bromide in high doses can alter the quality of baked fumigated wheat. Plant life is very likely to be damaged when fumigated at a temperature of 30oC or more. Cut flowers, fresh fruit, vegetables and some kinds of seeds are also very sensitive to fumigation with methyl bromide. Usually these commodities will also be damaged when fumigated in temperature and high doses. It is therefore advisable to ask opinion from experts or trial and error before fumigation carried out.

For the fumigation of fresh fruit and vegetables, fumigation companies must use temperature of the meat pieces for dose calculations, rather than the room temperature as in the fumigation other commodities. Fruit pulp temperature must be included in the Certificate of Fumigation. In measuring the temperature of the fruit flesh, fumigation company must take samples from at least one place in each of the bottom, middle and top party commodities. Temperature testing tool must be inserted into the center of a fruit that is located in the middle of the carton if possible.

Commodities are in trouble if fumigated with methyl bromide :


1. Foodstuff
a. Butter and fat.
b. Iodized salt is stabilized by sodium hiposulfit.
c. Saturated fat soy flour, wheat flour, flour protein
other high-starch and flour panir.
d. Nuts with high oil content.
e. Some baking soda, fodder (for example in the form
plates and contains nutrients and minerals), or material
Other foods that contain reactive sulfur compounds.
f. Animals with a mixture of bone meal.

2. Goods of leather (especially gloves or leather goods Other tanned with sulfur process).

3. Wool (high level of caution should be applied in fumigation
Angora wool. Some adverse effects have occurred on socks,
sweaters, scarves, and knitting yarn made from wool).

4. Viscose rayon, rayon that is processed or created through a process by using carbon bisulfida.

5. Photographic chemicals (not camera film or X-ray film)

6. Paper:
a. Paper silver polisher.
b. Certain other paper writing is preserved by a process
sulphide.
c. Photographic prints or blueprints stored in large quantities.
d. NCR paper.
7. Of rubber goods:
a. Rubber sponge.
b. Foam rubber, fillers such as rugs, pillows, cushions, mattresses
and the cover attached to the car.
c. Rubber stamps and the like, or recycled rubber.

8. Vinyl.

9. Fur animals.

10. Feathers of birds (especially in bird feather pillows).

11. Charcoal, coal, charcoal-shaped solid blocks and activated carbon.

12. Goods that are made of horse hair.

13. Oil paintings.

14. Sulfur-based paint.

15. Paper thin glass.

16. Polystyrene packaging

17. Seeds and seed plants.

18. Cut flowers.
