Health

Route of Exposure Symptoms First AidInhalation Fresh air rest. Refer for medical

What I learned

Extremely harmful to people if it comes in contact

It is used on vegetables fruits tobacco cotton and other farm crops similar to these.

Reflection

Is the reason for using the molecule good enough to justify the use of that substance?

Yes and No It is good because it keeps the insects off of our

food It is bad because if it comes in contact with us it can

be really harmful.
