Problem
John was going to buy a pesticide to control ants in his home.
When he was in the department store, he saw many types of pesticides.
• If he finds pesticide in different chemical groups, what group of pesticide he should pick up for home usage? Why?
(Specifically name a group. No long description or essay writing.)
• He (177 Ib weight) finally picked up a pesticide with LD50= 3500 mg/Kg. The pesticide is in powder and he has to apply it to the corners of his house. He has not worn any gloves and this powder is in continuous touch with his skin. The pesticide container contains 500 g powder (10% active ingredient). Do you think John will be highly toxicated up to the death?
