Aluminum in Amazon indicates: Worms reveal an invisible danger to the ecosystem, and also indicates the research conducted by UFPA | health
There are in normal organisms such as cooking tools, sweat -and -processed food, aluminum may seem harmless at first glance. But when it accumulates in water, it can bring the metal The risks of the bright For ecological systems – especially in Amazon. This is what a survey of the Federal University in Para (UFPA), which analyzed the effects of aluminum on microscopic worms known as the nematode, used as indicators of environmental quality.
The research is compared to a type widely used in international studies with two local types of Amazon: Tests were performed at different levels of aluminum, similar to those already registered in the Amazon water environments.
The result was surprised: C. Tropicalis species were the most affected, even with low concentrations. He reduced growth, less reproductive success and showed signs of environmental weakness.
“The changes in important parameters, such as reproduction and growth, can lead to the so-called” environmental death “of species-when the body no longer achieved its environmental role, which can lead to a decrease in the population or even local extinction and the main author of the study.
Search signs the first time that C. Tropicalis is used as a living object in toxic vital tests. According to the authors, this enhances the importance of using local species in environmental risk assessments, as original organisms can interact differently with pollutants compared to imported models.
Science to protect the Amazon
Under the directives of Virg Venekey and Lilian Lund Amado and support from the Brazilian Biological Research Union (BRC), the study strengthens the strategic role of Amazon science to protect the region’s biological diversity in an invisible but dangerous confrontation like aluminum.
“The unification of the use of C. Tropicalis as a living object is a more realistic evaluation of pollutants, as well as avoiding the risk of inserting alien species into tropical ecosystems,” said Ireraldo.
