Avoiding heavy pollution in Croyden is now easier, thanks to Croyden Council, who are providing ratings and maps of pollutants on their website. Levels of individual pollutants are rated on maps by a scale of colours and are updated each day. It is possible to zoom on the maps and ascertain levels on individual streets. This service is of special relevance to those with asthma and other health problems.
The council is also offering a service called AirTEXT that alerts medically vulnerable people via SMS messages. Patients with respiratory and heart problems will be targeted for participation at chest clinics and GP surgeries. They will be notified, before 8 a.m., when pollution levels reach moderate or high levels. The occurrence of this is estimated to be around 45 days per year. Alternatively, users can receive alerts via email. This initiative will prevent residents from having to discover pollution levels first-hand, and enable them to plan their days accordingly.
