A community’s groundwater has been contaminated by perchloroethylene after years of operation of a dry-cleaning business. Groundwater supplies a spring that feeds a pond and stream and is also the source for a well. A local family relies on the well for their drinking water and regularly eats fish caught in the stream and pond. The concentration of perchloroethylene in the groundwater is found to be 80 mg/L, and the chronic oral RfD is 0.006 mg/kg/day.
a.) Assuming all exposure to perchloroethylene comes from consumption of fish and water, and that children and adults eat the same amount of fish on average per day, calculate the Estimated Exposure Dose (EED) for an adult and a child.
b.) What are the adult and child hazard ratios (HR) for this scenario? Interpret the results.
The average body weight of an adult is 70kg, the average body weight of a child is 10kg, and the amount of fish consumed is 6.5g/day.

Produce a fully researched and referenced report (indicative
word range 2,250–2,500 words) for a client that explains a
particular system, type or design of an innovative modern method of
construction suitable for a new primary school.
Your report should:
• include a critical appraisal that evaluates the relative merits
of this method of construction over that of a more traditional type
of construction;
• address various environmental and sustainability issues.
Please state any assumptions you make in the report. Assumptions
can be made as to any specific type of facility, arrangements,
layout or size. Please ensure that you write in your own words and
that all sources are fully referenced.
Report guidance
The report could look at an offsite system of prefabricated
schools.
