Interesting ideas about the benefits of water development
Lions. After winning first the provincial and then national research project on the presence of arsenic in the water produced by 20 sixth graders Ipem Health and Environment of Libertador San Martin 256 earned the right to participate in the contest in August Junior Water, Sweden, sponsored by the Princess Victoria. The project is called “remove” technical home and is simple and cost effective to remove arsenic from water by solar oxidation. It is present in many soils, especially in the southeast of Cordoba.
The student development aims to reduce levels of arsenic from well water to reduce its harmful effects on human health. The process involves the simple use of steel wool (better known as “virulana”), plastic containers and lemon juice. Taking a water sample in the plastic bottle, you add steel wool and a drop of lemon juice. After the container is placed in the sun for six hours and allowed to sit overnight. Without shaking, filtered water with paper or canvas. Thus, arsenic is removed. In addition, you can purify water by adding two drops of bleach per liter.
The teacher research coordinator, Claudia Hernandez, said: “The consumption of groundwater with high arsenic causes cancer of the bladder, prostate, lung, stomach, kidney and skin, as demonstrated by international health organizations.” Hernandez says that with a cost weight of 20 liters of treated water with arsenic, for human consumption is safe.
Path. The 256 students Ipem research developed between 2009 and 2010. Last year, she was introduced at the 42 th Science and Technology Fair of the province of Cordoba. Among nearly 190 papers, took first place.
This distinction enabled him to represent the national contest in Cordoba, Argentina, organized by the Association for Sanitary Engineering and Environmental Sciences, where he competed against 19 projects in various provinces. Edgardo Felipe Devia and Badin was the students who presented the project. The intervening jury awarded the highest score to Ipem 256, relegating to second place at Lake Puelo (Chubut) and the third to General Alvear (Mendoza).
Junior Water Prize each year gives the Swedish state is intended for researchers from around the world between 15 and 20 who have developed water-related issues. Be delivered between 21 and 28 August in Stockholm. Argentina will be represented by 256 Ipem Lions. Participating countries of the world, only five will be speaking. In principle, a student will travel to Stockholm from Ipem 256 (setting out the project) and the faculty advisor Hernandez, although there are likely to join another student.
