The La Plata region in Argentina has been infested with cyanobacteria. Dense, bright green patches appear at many points along the coast, and local authorities warn against entering the water. This is especially painful for the inhabitants of Buenos Aires, who seek refreshment in La Plata on hot summer days.

La Plata is an estuary in South America – the vast estuary of two rivers, the Paraná and Uruguay, into the Atlantic Ocean. Two capitals are located above it: Argentinian Buenos Aires and Uruguayan Montevideo. For some time, however, the region has been struggling with blooms cyanobacteria. One of them is currently underway along the coast of Buenos Aires Province.

It is forbidden to enter the water

An orange cyanosis alert has been issued along the coast of La Plata. Local authorities warn that the greatest danger is in the towns of Quilmes, Berazategui, La Plata, Ensenada, Berisso and Magdalena, along more than 80 kilometers of the Argentine coast. The alert also applies to offshore water bodies in the province.

An orange alert indicates a medium risk of negative effects from exposure to cyanobacteria. As explained by Guillermo Jelinsky of the Buenos Aires Department of Water Resources Management, special care should be taken with pets, which may suffer from health problems once they enter the water.

“It is recommended that contact with water be avoided or kept to a minimum,” the official said. – You must also ensure that children do not enter the water, and do not eat any fish from the area where cyanobacteria appeared.

Historically bad conditions

The rapid growth of blue-green algae in the La Plata region is caused by overfertilization of waters – excessive availability of nitrogen and phosphorus for fast-growing bacteria. Jelinsky added that the situation was exacerbated by “historical” climate anomalies, including droughts.

The inability to cool down in the waters of the La Plata estuary is a big problem for the inhabitants of Buenos Aires. It is currently summer in the southern hemisphere, and in the area of ​​the Argentine capital, temperatures reach over 30 degrees Celsius.

What are cyanobacteria?

Blue-green algae (cyanobacteria) are a group of self-sustaining bacteria. They occur both in salty and inland waters, floating freely in the water depths. As a result of overfertilization of waters and in appropriate weather conditions, they cause mass blooms, most often in shallow, coastal waters. Some cyanobacteria produce toxic substances, and contact with them can cause irritation of the skin and mucous membranes, headaches, fever, nausea or vomiting. In particularly severe cases, damage to internal organs or the nervous system may also occur.
