Homework 3

Scope

Defines the purpose of the assessment: why is it done?

Talvivaara mine has been alot on news becauce of environmental problems. Escpecially leakages to natural waters but local air quality broblems have occurred too. Rock crushing plant creates alot of mineraldust (PM10 and PM2,5).

Question

A research question that the assessment attempts to answer.

Is the outdoor air quality a health hasard to miners?

Intended use and users

List of users that are supposed to need the assessment. Also, how do we expect them to use the information?

Talvivaara mining company Kainuun ELY-keskus (Centre for Economic Development, Transport and the Environment)

Company wants to know is the air quality in acceptable level. They need infomation about when and where the worst concentrations occur. Company can do shanges to reduse emissions if needed.

ELY-keskus needs to know is the air quality legal and safe to workers. ELY-keskus can impose the company to reduse emissions if needed.

Participants

Who is needed to participate to make the assessment a well-balanced and well-informed work? Also, if specific reasons exists: who is not allowed to participate and why?

A consultant to measure air quality.

Company

Ely-keskus

DARM group

Scenarios

Decisions and decision options considered. Also, if scenarios (defined here as delibarate deviations from the truth) are used, they are described here. For example this is a scenario: "Let's assume that the whole population is exposed as much as the maximally exposed individual, because we want to see if even the worst-case scenario causes concern."

Rock crushing plant:

BAU or reducing emissions with some tecnique.

Analyses

What statistical or other analyses are needed to be able to produce results that are useful for making conclusions about the question?

Answer

Results

What are the results of the analysis?

Conclusion

What is the conclusion about the question based on the results obtained?

The best option is...

Rationale

Endpoints

• What are the stakeholders that we should consider?
• What are the endpoints that a stakeholder is interested in? How would the stakeholder summarise the endpoints to derive an overall preference ranking for outcomes of decision options? Think about this separately for each stakeholder.

Variables

• What are the issues that should be looked at to be able to understand the outcomes of the decision options?
• Typically, with health impact assessments:
  • What emissions and exposures should be considered?

Emissions from rock crushing plant:

Exposure of mineral dust PM₁₀ and PM_2,5

• • What health endpoints should be considered?
  • What exposure-response functions should be considered?

• • What population subgroups should be considered?

Workers who breath raw outdoor air fo many hours per week.

Workers who has low quality air conditioning in their vehicles.

Workers who has high quality air conditioning in their vehicles.
