 * Background Information**

Roundup is a product sold in America, and it does have mercapturates. They are only band form small gardens, like home-owned gardens. Only large plantations are allowed to have herbicides. There doesn’t seem to be band from other countries.


 * Health, Environmental, Economic, and Political Implications**

Most of the herbicides in use today are known to be mutagenic, carcinogenic or teratogenic. In other words they can cause spontaneous mutation, radiation hazards, and birth defects. Other alleged health effects can include chest pain, headaches, nausea and fatigue. They can contaminate the water system via surface-runoff. Most herbicides decompose rapidly in soils via soil microbial decomposition, hydrolysis or photolysis and some herbicides are more persistent with longer soil half-lives (quantity of decay). Certain herbicides affect metabolic pathways and systems unique to plants and not found in animals making many modern herbicides among the safest crop protection products having essentially no effect on mammals, birds, amphibians or reptiles.

Detecting Exposure: The metabolite atrazine mercapturate is a biomarker of atrazine exposure and can be measured in urine. Within minutes all of the mercapturate is exported to the medium, while the GlcN-Ins is retained in the cells, and recycled back into MSH [ Newton00a ]. In general, the mercapturate is more polar and more water-soluble than is the parent electrophile and is readily excreted. To determine if a hydroxylated mercapturate is produced in vivo, we treated male Sprague-Dawley rats with either benzene (600 mg/kg), phenol (75 mg/kg), or hydroquinone (75 mg/kg) and collected the urine for 24 hr. thioTEPA-mercapturate is likely the result of glutathione conjugation, after which the glutathione adduct loses two amino acid residues in separate stages.

Farmers would have trouble with their products and would cause depletion in produce products. It is banned for personal use, but not farm use. So it would only affect the farmers since it is already banned for personal use.


 * What is your position on the chemical? What action, if any, should be taken?**

I don’t really care about this chemical. But it does seem to be very hazardous. I think it should be dealt with. So many people use it so I think it will be hard for us to get rid of it.

__**Summary Section**__
Summarize the costs/benefits and draw a conclusion as to what actions if any are necessary.


 * Mercapturates**

You should basically avoid physical contact with this chemical. It can be very dangerous if you don’t know what you are doing. I think that this chemical is too dangerous for public use. We need to be more careful about what we use on plant life.

This chemical is best used to kill weeds and is the most efficient way to kill them. There are many farmers that use this chemical to kill the weeds in their crops. They use Crop dusters to spread this chemical over the field.

The cost of getting rid of this chemical may not be that hard. There are many substitutes that we can use to kill weeds. We could use vinegar for one. And there are some other things that we could use. They may not be as efficient as herbicides, but it might be safer to use them.
