toxicological issues


The assessment for Unit VIII is the preparation and submittal of a Course Project. By the end of Unit IV you should e-mail your proposed outline and approach to the topic for review and approval prior to beginning work.
You have been called to a hazardous waste site to assess the toxicological issues involved at the site. You are given the following information regarding the conditions at the site:
?
The site is an abandoned industrial site. It has been used by two now-Defunct
companies in the past 60 years.
?
One stream, which is a popular fishing
stream, runs through the site.
?
There are 100 unmarked drums buried on the site. Many of the drums are rusting and showing signs of cracking.
There is a general strong smell of pungent
chemicals in the air near the dr
ums.
?
The site is located approximately one mile upstream of a residential area and a surface water withdrawal po
int for
the local water supply.
?
Water is also withdrawn downstream from th
e site for irrigation purposes.
?
Althou
gh the drums are unmarked, it is known that wastes from the previous
industrial activities included:
o
PCBs
o
Chromium waste
o
Acrylamide
o
Toluene diisocyanate (TDI)
You are asked to write a report on the toxicological issues at the site. Your report should
include the following sectio
ns:
1.
An overview of site
conditions as described to you.
2.
An analysis of each of the known wastes at the sit
e. The analysis should include:
o
A description of the issue and state the purpose for the report
A description of the toxicants common routes of exposure
Mechanisms of toxicity
Exposure limits for the toxicants
3. A brief overall risk assessment of the site based on the four steps of risk assessment outlined in Chapter 25.
4. A recommendation of what actions should be taken at the site based on your toxicological assessment.
Your report (paper) should be 5-7 pages in length. The title page and reference page are not included in the required paper length. Your paper must contain at least five references, and may include Internet sources, books, and professional journals or resources related to the profession. CSU requires that students use the APA format in writing course papers.
