Климатические изменения сделали озера смертельно опасными для людей

Среда пресных водоемов обогащена питательными веществами и хорошими условиями для интенсивного роста цианобактерий, грозящих людям смертью.

Американские исследователи заявили, что обильное цветение водорослей, спровоцированное климатическими изменениями, загрязняет атмосферу Земли смертельными токсинами. Об этом говорится в статье, опубликованной Science Alert.

Кроме цианобактерий – водорослей сине-зеленого цвета, водоемы страдают от стока отходов сельского хозяйства, которые при испарении также выделяют в воздух токсичные вещества.

Водоросли выделяют анатоксин-а (АТХ). Имено он является причиной затрудненного дыхания, спазмов в мышцах, конвульсий и способен повлечь за собой летальный исход, остановив дыхание.

Эти микроорганизмы, в свою очередь, снижают уровень кислорода в воде, что приводит к смерти рыб и других обитателей водных плес.

Кроме этого, существуют некие условия, при которых анатоксин-а может попадать в воздух.

«В период с июля по октябрь 2019 года мы собрали пробы воды и в воздуха у края пруда Капаум в Массачусетсе. 11 сентября 2019 года во время ветра и туманной погоды, ATX был зафиксирован в высокой концентрации — 21 нанограмм на миллилитр. Также токсин был найден в воздухе в его средней концентрации — 0,87 нанограмма на фильтр, то есть, 0,16 нанограмму на квадратный метр», — утверждают специалисты и предостерегают об опасности цианотоксинов для здоровья людей.

Напомним, в Одесской области искусственное озеро Сасык, возле Килийского и Татарбуранского районов, зацвело ядовитыми водорослями, которые губят все живое.
