Environmental health internship portfolio

I am a Resident physician in training (Neurologist). I am pursuing an MPH degree (Environmental Health Concentration). I need to write a portfolio (for internship) explaining the environmental health aspects of my training (i.e. my service through treatment of Seizures, strokes etc).

The portfolio need to cover the different aspects of environmental health that I practice everyday. In addition to treating patients with the above public health problems, other aspects of public health (dealing with brain injury patients, infections, health education, community service and occupational health(treatment of people exposed to heavy metals at work etc)) can be talked about. Feel free to call me if you need anymore information.
