Environmental pollution causes toxic blue algae to thrive in China

Sao Sao Lake, the section that flows into Song Kieu River, Anhui Province, China on June 14 green blue algae, stretches 1.5 km from the shore to the middle of the lake.

Cyanophyta, which is actually cyanobacteria, is generated by water eutrophication.Excess nitrogen, phosphorus from agricultural and industrial waste, plus warm weather, facilitates cyanobacteria "blooming".

Cyanophyta reduces the concentration of dissolved oxygen in water, degrades aquatic ecosystems.In addition, green algae can produce toxins that affect the nervous system, liver failure, and contact allergies.

Cyanophyta also affects water sources for living and irrigation.Boiling water does not kill algae toxins but also releases more toxins.

However, this man was not afraid of poisonous algae, still diving into the fishing lake.

According to experts, the effective way to prevent cyanobacteria is to treat rainwater, agricultural and industrial wastewater before discharging into the lake, planting many trees along rivers and lakes.
