This project investigates the use of immobilized Chlorella vulgaris, encapsulated in agar-agar spheres, to bioremediate freshwater contaminated by industrial discharges. Utilizing a 2-liter bioreactor, significant results were achieved over six days, including a 96% reduction in chromium and a 90% reduction in copper concentrations. The process also showed substantial decreases in total nitrogen, ammoniacal nitrogen, and phosphorus levels, proving its high effectiveness.

This technology offers practical advantages, including high contaminant removal efficiency, low cost, and ease of use in various environments. The research emphasizes supporting vulnerable communities dependent on water. In regions with limited access to advanced technologies, this cost-effective solution enables self-sufficiency and sustainability in water management. By leveraging locally available materials and accessible methodologies, it provides sustainable water treatment, fostering resilience and long-term environmental stewardship.

Currently the existence of microplastics in different bodies of water is becoming a problem for the ecosystem of many species, including humans. For this reason, we evaluated the efficiency of ferrofluid as a technology for the extraction of microplastics in water samples.

The work carried out was aimed at assisting oxidative processes, for the treatment of water effluents with organic substances contamination. The methodology employed was consistent with a primary oxidation by the action of ozone (ozonolysis), followed by a photocatalytic oxidation, by the action of photocatalysts activated by ultraviolet radiation.

To check the efficacy of the proposal, an experimental pilot plant was designed to test and evaluate the process under scale conditions, providing as an advance the specificity of the photoactive catalysts by ultraviolet light, in conjunction with an ozone producer as a coadjuvant of the process.

The technological development was verified through a simulation in the prototype with a river effluent with high organic pollution, testing the progress of the process through Chemical Oxygen Demand (COD) measurements.

The results obtained showed a high degradation rate of organic matter, above 70%, with a 3rd order reaction kinetics. These values give us an optimistic expectation when it comes to choose a viable treatment for this type of effluent.

Patagonia has a cold climate with a dry season during the mosquito breeding period. Little is known about the reproductive habitats in Patagonia and Aedes aegypti was found in Neuquén. Climate change could encourage mosquito migration to cold areas. Objective: to characterize the reproductive habitats of mosquitoes and identify the genera in Junín de los Andes. Methodology: hydrosphere and biosphere protocols of the GLOBE Program were applied. Results: Only the genus Culex sp. was found. The puddles are protected by trees and herbs, the water quality between the puddles is similar, with little oxygen, high turbidity and alkalinity. The diversity of macroinvertebrates is low compared to the river. Knowing the breeding habitats allows to design prevention and control systems.

A method for family households is employed to obtain drinking water from river water by treating it with seeds of
Moringaoleifera lam. The seeds will eliminate the river water turbidity. Subsequent heat or chemical disinfection
is needed. The number of seeds used is adjusted to the water turbidity by a self-designed dispenser. In the tests
carried out, after its application, the results obtained were found within the limits indicated for drinking water.

The World Health Organization and the Pan American Health Organization (PAHO / WHO) had expressed the importance of adopting a series of measures to help prevent Aedes aegypti-borne diseases, constituting a public health problem in our country and registering dengue outbreaks in 15 jurisdictions as from August to September 2016, being the worst epidemic in history.
The situation demands the urgent need to seek appropriate measures to find new control methods that do not cause environmental problems. Therefore, it was decided to locate biocontrol agents to fight for the important population vector control in their aquatic phase.
In addition, the predatory capacity of Hoplerythrinus unitaeniatus (caballita) was proved exercising an important control of Aedes aegypti population in the home environment.
