Sargassum seaweed phenomenon<\/h2>\n
\n

Sargassum seaweed \u2013 brown algae<\/strong>\u00a0also known as\u00a0\u2013 is a type of algae that evolved in huge beds in the Atlantic (some beds exceed 45 km in diameter). On the Caribbean coast of the Atlantic since 2011\u00a0Large-scale strandings of sargassum seaweed have become a real environmental and public health problem.\u00a0<\/strong>West Indies<\/strong>\u00a0And\u00a0French Guiana<\/strong>\u00a0is regularly affected by this condition, and other countries in this region are also affected: coastal Mexico, the Dominican Republic, Puerto Rico, Cuba, and even Florida sometimes\u00a0one meter<\/strong>\u00a0capable of exceeding\u00a0from toxic sargassum seaweed accumulations<\/strong>\u00a0is affected.<\/p>\n

Tens of thousands of tonnes of sargassum algae (more than 40,000 tonnes) in 2018\u00a0Guadeloupe<\/strong>\u00a0,\u00a0Martinique<\/strong>\u00a0,\u00a0Saint-Martin<\/strong>\u00a0and even\u00a0to the shores of Guyana<\/strong>\u00a0shot . Sargassum algae accumulates on shores, trapping marine animals, blocking ship access and\u00a0Decomposition releases toxic gases<\/strong>\u00a0. To deal with these dangers, in June 2018\u00a0sargassum programlar\u0131<\/strong>\u00a0was started. On the hardest-hit islands of Guadeloupe and Martinique, local authorities and communities are developing actions: to verify health risks and environmental hazards\u00a0measuring sargassum gas concentrations<\/strong>\u00a0campaigns for, depending on residential areas and the most popular beaches\u00a0cleaning works, coastal\u00a0<\/strong>collection of sargassum algae beds<\/strong>\u00a0\u2026 Closing schools located near beaches and cleaning at the height of the tourist season are the first responses to the sargassum phenomenon.\u00a0affecting the health, environment and economy of the inhabitants of those countries<\/strong>\u00a0a problem .<\/p>\n<\/div>\n

Why are sargassum algae poisonous?<\/h2>\n

Sargassum gas: hydrogen sulfide and ammonia<\/h3>\n
\n

Even though sargassum algae are not poisonous on their own, they can enter the decomposition phase when washed ashore.\u00a0toxic\u00a0<\/strong>gases<\/strong>\u00a0They reveal\u00a0.<\/p>\n

The gas released by sargassum algae consists of two main elements.<\/strong>\u00a0consists of:<\/p>\n

    \n
  • Colorless substance found naturally on Earth<\/strong>\u00a0hydrogen sulfide\u00a0(H2S), which is a gas.\u00a0It is produced by the decomposition of organic and bacterial substances<\/strong>\u00a0and\u00a0can also be produced industrially. hydrogen sulfide,\u00a0Harmful effects on health from 10 ppm<\/strong>\u00a0and in high concentrations\u00a0fatal\u00a0<\/strong>toksik bir gazd\u0131r .<\/strong><\/li>\n<\/ul>\n
      \n
    • The decomposition of sargassum algae also releases\u00a0ammonia\u00a0(NH3) \u2013 also known as hydrogen nitride (composed of nitrogen (N) and hydrogen (H2)). Ammonia,\u00a0even at low concentrations\u00a0It is a flammable, explosive and poisonous gas.<\/strong><\/li>\n<\/ul>\n<\/div>\n

      Health effects of sargassum gas<\/h3>\n
      \n

      Gases released by the decomposition of sargassum algae\u00a0It is quite poisonous<\/strong>\u00a0(hydrogen sulfide and ammonia). Being exposed to and breathing these gases,\u00a0even at low concentrations,\u00a0<\/strong>many dangerous effects on health<\/strong>\u00a0why could it be .<\/p>\n

      Symptoms and risks of sargassum gas:<\/strong><\/p>\n

        \n
      • Eyelash<\/strong>\u00a0irritation (conjunctivitis, discomfort in bright light)<\/li>\n
      • Respiratory system<\/strong>\u00a0irritation (hoarseness, cough, chest pain)<\/li>\n
      • incoordination<\/li>\n
      • chronic poisoning<\/strong>\u00a0In case of: bronchitis, respiratory and skin irritation<\/li>\n
      • acute poisoning<\/strong>\u00a0In case of: dizziness, respiratory arrest, cardiac arrest, loss of consciousness<\/li>\n<\/ul>\n

        Additionally, people with asthma, children, and pregnant women are more sensitive to the health effects of these gases. Finally,\u00a0at a certain level of concentration\u00a0hydrogen sulfide<\/strong>\u00a0(H2s) and\u00a0amonya\u011fa (Nh3) maruz kalmak\u00a0<\/strong>can lead to death<\/strong>\u00a0(100 ppm for NH3 and 1,000 ppm for H2S).\u00a0Brown algae off the coast of the West Indies\u00a0revealed by decomposition\u00a0<\/strong>revealed by sargassum gaz\u0131decomposition\u00a0<\/strong>a real danger<\/strong>\u00a0constitutes .<\/p>\n<\/div>\n

        How to monitor sargassum gas?<\/h2>\n
        \n

        The hydrogen sulfide and ammonia that make up decomposing sargassum seaweed emissions can be detected by smell \u2013 a rotten egg smell for H2S and a pungent odor for NH3. However, olfactory perception decreases as concentrations released by algae increase.\u00a0When it is more than 50 ppm for NH3 and 100 ppm for H2S, it becomes impossible to distinguish these odors. This\u00a0<\/strong>olfactory fatigue effect<\/strong>\u00a0It is called\u00a0. To prevent this and accurately measure the concentrations of these toxic gases\u00a0It is necessary to use a special gas detector<\/strong>\u00a0.<\/p>\n

        Among all available gas detectors,\u00a02 solutions in particular\u00a0<\/strong>monitoring sargassum gases<\/strong>\u00a0Suitable for:<\/p>\n

          \n
        • Portable single gas detectors<\/strong><\/strong> \n

          This,\u00a0It is the most cost-effective solution but\u00a0<\/strong>multi gas detector<\/strong>\u00a0It is less useful than using\u00a0. To monitor the presence of toxic gases released by sargassum seaweeds\u00a0two portable single gas monitors<\/strong>\u00a0required: one for hydrogen sulfide (H2S monitor) and one for ammonia (NH3 detector). The most commonly used device for this application is\u00a0Does not require special care<\/strong>\u00a0\u00a0such as the\u00a0Senko SGT gas detector\u00a0for\u00a0It is a disposable gas detector<\/strong>\u00a0.\u00a0or<\/li>\n<\/ul>\n

            \n
          • Portable multi-gas detectors<\/strong><\/strong> \n

            Using only one device to measure targeted gases\u00a0is more suitable<\/strong>\u00a0. A device equipped with NH3 and H2S sensors\u00a0multi gas detector,\u00a0<\/strong>properly monitoring sargassum gas concentration levels<\/strong>\u00a0can be used for . Additionally, other sensors can be added to the device, such as CO or CO2, which are potentially released (at lower concentrations) during the decomposition process of algae.<\/li>\n<\/ul>\n

            These two types of detectors measure\u00a0gas concentrations in air (expressed in ppm).\u00a0etkili bir \u015fekilde izleyebilir<\/strong>\u00a0and on the dangers of sargassum seaweed\u00a0may give a warning.<\/strong><\/p>\n

            How to protect against sargassum gas?<\/h2>\n
            \n

            Governments are responsible for the toxic emissions of decomposing sargassum<\/strong>\u00a0He made\u00a0different suggestions to combat its effects. For example, in the French West Indies, areas with more than 5 ppm H2S were closed to people not wearing appropriate respiratory protective equipment<\/p>\n

            People operating in polluted areas with toxic gases such as ammonia and hydrogen sulfide should not have gas detection units.<\/strong>\u00a0In addition\u00a0with adapted respiratory protection masks<\/strong>\u00a0needs to be equipped\u00a0.<\/p>\n

            Therefore, people who collect or treat sargassum seaweed should be advised for short-term interventions.\u00a0with ABEK filter<\/strong>\u00a0Must use an equipped respiratory protective mask. Fully shielding the wearer's face, as brown algae emissions can irritate the eyes.\u00a0full face mask<\/strong>\u00a0It is recommended to use it (instead of a half mask).<\/p>\n
