There is a lot of research on many other aspects being carried out it space for medical purposes. Space-based hyper spectral imaging as a matter of fact be used in mapping pollution via spectral analysis of chemical signatures. This can be used for public awareness and to intimate the government so that the necessary steps can be taken.
Even measuring water pollution from industries can alert citizens of the contents of the water they are drinking and help maintain the chemical disposal standards of different industries.
A new emerging field of work is vector movement monitoring. Monitoring environmental change and the emergence of diseases based on government repositories can help identify the subtle factors of diseases like heat waves or monsoon season. Monitoring pollutants and allergans and linking those with machine learning to the disease repository of hospitals to guage and cure patients of persisting problems. This generic understanding of pollutants and allergans can be used by pharmacies or hospitals to stock enough supplies for asthamatic or respiratory ailment patients. These alerts as observed through satellites can greatly help providing quality healthcare to all affected in say when pollen is seen increasing over areas or perhaps increase in SPM. Any increase in Allergan can be alerted through a satellite to the hospitals and even people so that those with extreme respiratory illness can use mask to prevent detrimental effects to their health.
