In this article, it is explained how exposure to the particles of the size collected in the study can lead to chronic respiratory infections, aggravate asthma and increase cardiovascular risk. Air samples were collected over 90 minute intervals at several sites in Iraq which contained dust, lead, aluminum and other metals. These amounts exceeded U.S air quality standards. The particles found could evade hairlike projections in the nose and trachae and penetrate deep into the lungs. The air probably results from a mix of natural and man-made sources. Iraq has clay deposits, zinc, lead and silicate minerals that get swept up in dust storms in the region several times a year. The major fear and concern is the potential long-term health ramifications.
My experiment in the article was an example of a hypothesis based science because there were various tests over 90 minute intervals in several places, therefore it was a hypothesis based science experiment.
These findings can prevent the people who live in Iraq from developing health problems such as asthma and increase cardiovascular risks. If it continues like that with no change, it could affect the lives of many who live in Iraq.

I think you may have to rethink your conclusion that this is an example of hypothesis-based science. Data was collected every 90 minutes but did any tests were performed?
