1

What is differences between occupational and environmental exposure

Occupation - higher exposure and effects more obvious
Environment - more subtle and lesser degree

2

What can affect exposure

Personal - fixed influences such as genes or variable influences e.g. exposure to infection
Population - fixed influences such as geography

3

What is developed if population affected and what does it depend on

Policy
- Size of effects
- Acute or chronic
- Politics

4

Routes of exposure

Inhalation
Through skin
Ingestion
Mechanical loading

5

How do you measure exposure

Can be difficult if cumulative
Biomarkers?
Direct measure
Indirect measure
Statistical modelling for estimates it not possible

6

How do you recognise environmental cause

Population exposure to substance increases disease

Cluster of disease in time or place

Analogy of exposure to other proven exposure / outcome situations elsewhere

7

How do you recognise diffuse source e.g. air pollution causing respiratory disease

Only identifiable my statistical analysis over time

8

How do you recognise point source

Specific source causing outbreak
Public health issue to see if resources to control

9

What is analogy

Likelihood of interaction between different exposures
Media often picks up first

10

What is environmental legislation

Changes as different hazards are identified and quantified
e.g. Air Quality / emissions
