Committed to improving the purpose
of global geo-health data

The research team at the Global Geo Health Data Center (GGHDC) is introducing the Personal Exposure Scan, a user-friendly website that provides data of five exposomes: air pollution (as proxy for NO2), fast-food, urbanity (greenness), heat island effect, and noise.

Like to understand the impact of environmental change on health? The best way to find out is an online visit to the GGHDC Personal Exposure Scan. This website enables you to view the personal environmental exposures of a particular type of person living at that location, for each location in the Netherlands. Simply select a type of person, as this will configure the values shown for an activity pattern typical for that person.

Healthy or unhealthy factors

The website uses simplified exposure assessment techniques and is thus mainly meant to offer you a first glance on how much you are exposed to healthy or unhealthy environmental factors.

Each exposome is based on open source data and recalculated as to give an indication of the intensity of the exposome at a given location.

In the scan database, researchers in the GGHDC have defined eight profiles. Each of these profiles have their own distinctive exposure. The activities patterns in profiles differ, and for each activity a specific time period is determined, adding up to 24 hours (i.e. a day).

Eating or sleeping?

The team has discerned four activities: being at home (e.g. for eating and sleeping, being at work, commute from and to work, and additional (e.g. time for sports or hobbies).

Because it is unknown where everybody works, GGHDC researchers have defined radii for each profile wherein we expect anybody to work. A commuter by car has a larger search radius than a commuter by bike, and they both have a larger radius than a home worker.

For instance:

– a baby will spend most of its time at home, asleep. A baby living close to a big road will have higher accumulative exposure to air pollution than a commuter, who can work away from a big road, thereby mitigating his or her cumulative exposure

– A cycling commuter will travel to work not too far from his or her work, and by traveling will accumulate different exposures than mentioned baby

– a home worker will spend a large amount of time in or near home, comparable to a baby’s profile. However, the home worker will have a larger radius for additional activities.
