After reviewing Safety Data Sheets (SDS) and conducting an initial inspection of the areas at Acme

Automotive Parts (AAP), you identify the following health hazards that you want to further evaluate:

• manganese fume (hand welding);
• copper fume (hand welding);
• lead fume (hand welding);
• 1,2,4 trimethylbenzene (paint booth);
• toluene (paint booth); and
• xylene (paint booth).

Choose one of the compounds from the hand-welding operation and one of the compounds from the paint booth operation. Search the Internet, and find the following data concerning the two compounds you chose; LC50, IDLH, vapor pressure, vapor density, target organs, mutagenicity, carcinogenicity, and reproductive toxicity.

(Hint: many of the variables can be found on SDS that can be accessed on the Internet).

Write one paragraph on each of the compounds explaining what the data tell you about the most likely exposure route and risk associated with each compound.

U of T Invention of Watermills Make to Greek and Roman Civilization Questions

3 questions

You should not need to spend more than two hours in total on this assessment exercise.

1.What difference did the invention of watermills make to Greek and Roman civilization?

2.Why does the archaeological site at Abu Hureyra matter for the history of energy transitions?

3.What do you think is the biggest single advantage of an agricultural lifestyle as opposed to relying only on foraging, and what is the single biggest disadvantage?

4.How do the changes in energy technology that we have looked at so far seem to have been related to changes in human diseases?

5.Is it important to understand the “fall” of the Roman empire? Why?

6.How does an understanding of the available energy technologies help us with the history of a complex pre-industrial society such as Classical (5th and 4th century BC) Athens?

7.How, and how far, does Hesiod’s Works and Days support Ian Morris’s arguments about the values held in farming societies?

8.What were the most important contributions, in energy terms, that non-human animals made in pre-mechanised agriculture?
