Consider a scenario in which this population experiences an increase in the long-term environmental concentrations of lead in their water, and the variance of environmental concentrations in this simulated population expands. If the median value of the raw water environmental concentration data increases to 25 ug/L, and the GSD increases to 3.5 ug/L, holding all other simulation input parameters constant, what is the increase in median concentration (in ng/kd-day) of lead intake? Hint: You'll need to note the results of your original simulation run, make an adjustment to the code to incorporate your new simulation parameters, and then compare your adjusted results to the results of your original simulation to answer this question. 

We discussed an example of exposure assessment with the case study of formaldehyde exposure in individuals living in FEMA trailers following Hurricane Katrina in 2005.  The CDC came in and did air monitoring.  In order to assess exposure, they needed to… (mark all that are correct).

In the environmental health risk equation "Risk = Hazard x Exposure," what does "exposure" specifically refer to?

Pedersen Industries wants to initiate a new project. To facilitate the project, an increase in cash of $20,000 will be required and the firm needs to build up $15,000 in inventory. The firm is expecting revenues of $500,000 per year and cost of goods sold (COGS) of $400,000. Pedersen Industries is expecting that Accounts Receivables (AR) will account for 5% of annual sales and Accounts Payables (AP) will account for 10% of COGS. All these changes will occur in year t=1. ​ What is the incremental cash flow effect from the change in Net Working Capital (NWC) in year 1?
