The gastrointestinal tract and inhalation

Pollution Prevention by Paul L Bishop
1) What are the molecular modifications that can be made to reduce absorption by the gastrointestinal tract and inhalation?
2) Discuss the steps involved concerning the development and implementation of a pollution prevention plan for a large three shift manufacturing operation that employs over 300 people and has multiple operating units such as shipping/receiving, administrative offices, raw/finished product storage, warehouse facilities, quality control laboratories, and manufacturing.
3) Why do firefighters recommend the use of a deluging volume of water when extinguishing an oxidizer-supported fire? What may happen to a large (i.e., 30-50lb) container of trichloro-s-triazinetrione, or calcium hypochlorite, if it is left to sit in the water and muck remaining in a building after fire fighting efforts have ended, but clean-up will not begin for several days? The assumption here is that the plastic container has been compromised in some way by the heat of the fire and possibly creating cracks in the base or sides.
4) All ammonium compounds, which contain an ammonium ion (NH4+) and a negative ion, are thermally unstable.
A. Discuss two ways that ammonium compounds decompose when they are heated. What chemical reaction is involved in the thermal decomposition of ammonium persulfate?
B. What is the most likely reason OSHA requires ammonium nitrate to be segregated for sulfur or finely divided metals? Explain your answer.
C. What is the most likely reason OSHA requires employers to protect flooring and handling areas in buildings against impregnation by ammonium nitrate and requires that the floors be constructed without open drains, traps, tunnels or pits into which molten ammonium nitrate could flow and be confined in the event of a fire?
5) U.S. companies export pesticides that have been banned or restricted in this country. Should this practice be allowed to continue? Please give a specific answer and support your rationale or logic.
6) Make a list of some food additives found in your home. Review the literature and show their ingredients and adverse effects. Cite at least two reference sources in your response.
7) List aromatic amines used in industry and discuss their toxicological effects.
