The monitoring of the emissions resulting from the decomposition of the sargassum algae by ENVEA's micro-sensors is not recent. Measurements of H2S concentrations carried out at the national level by the Air Quality Monitoring Association in the vicinity of natural sources such as the degradation of green algae (west coast of France) or sargassum algae (Martinique, Guyana) have been in place for several years.
Back in 2015,Madininairhad already been appointed by local authorities in Martinique to set up a monitoring network of hydrogen sulfide and ammonia concentrations in urbanized areas impacted by the stranding of these algae. This pioneer network allows a real time and continuous monitoring of H2S and NH3 concentrations.

Following the update of health recommendations and the management measures of the High Council of Public Health (HCSP, France), the Regional Health Agency and GWAD'AIR (Approved Association for the Monitoring of Air Quality) have deployed a network to measure hydrogen sulfide (H2S) and ammonia (NH3). The daily data collected are available on the Gwad'air website:

The new installed network of 24 Cairnet stations to measure the Sargassum algae gas emanations provided by ENVEA Cairpol and installed by Gwad'air end of August has been inaugurated by the French President Emmanuel Macron during his trip to the Antilles this Friday, September 28th.
