Industries have installed themselves near rivers and streams and are throwing their waste to water. 

The waste that the industries produce,contains heavy metals such as Arsenic and Iron which have deadly consequences in the human body. 

Buenos Aires, Argentina- As the power plant and economic centre of the country, the city is full of companies and industries. Because there isn?t an easy way of disposing the trash chemicals introduce themselves in the waterworks of the area.  This come from chemical factories and industries. 

It isn?t a new issue, in 1953 residents of the neighbourhood of La Matanza, in the proximity to the Matanza river, denounced the toxic chemicals that were inserted into their water source and rise of illness. According to the Argentinean Code of Nutrition (CAA) the accepted quantity of Iron is 0.05 mg per litre in water. The rivers had more than this limit established by the government.

The population group that is the most affected by the contamination is the lower class. Since this poorer neighbourhoods rely on the rivers for drinkable water and else, they are likelier to get sick from ingesting the heavy metals.

These heavy metals can be ingested, breathed or touched to be absorbed by the human body and have very lethal consequences. These affect different parts of the body from the lungs, bones and blood to the neurons of the brain. In children it causes impediments in their development.

I think this topic is relevant because it isn't talked about that much. I only found out when I had to made a presentation for school about it and what I found out shocked me at that time.
