In the next article, we will ascertain to test if mercury can be absorbed from water through mango, more precisely a mango seed, in the same way some proteins do, like the albumin  that transports metals through the body. It's known that the mango seed its composed of 6.39% raw protein being the most relevant factors: globulins 40.16%, insoluble proteins 23.84%, glutenins 15.81%, albumins 12 11% and prolamins 8.08%. The mango seed passes through a dehydration process then once it's completely dehydrated its grind until it's in millimetric powder, a screening its made till it reaches 150 microns. Once the water is decontaminated it will pass through some test to determine their viability, we will analyze the results and draw conclusions in base of them. The mercury in the water its a problem with a raising concern in our communities, since its frequency is incrementing in lakes and oceans as time passes. The seafood we ingest have mercury in their organisms and these causes respiratory, renal and cardiovascular problems, among others. Hence lies the importance of our investigation to decontaminating water.
