Answer:
Industrial effluents, mainly those resulting from steel activities, are human activities that have increased the amount of lead in drinking water.
Explanation:
The inadequate disposal of industrial effluents, mainly those resulting from steel mills, has caused significant contamination of water and soil by lead. This can cause serious risks of contamination to animals, including humans, who need water and food that are generated in the soil to survive.
The best way to filter this element from drinking water, is through a nanofilter made of aluminum oxide, which does not have a high economic cost to be produced, allows total filtration, leaving the water ready for consumption. However, the most correct way to avoid water contamination is to not allow industrial waste to be disposed of inappropriately.
