Unexpected effects from onions, garlic

According to a study published in the International Journal of Environment and Pollution, onions and garlic removed from the food industry can be used to remove toxic heavy metals like arsenic, Cadmium, iron, mercury, lead and tin in contaminated substances.

Biotech researchers Rahul Negi, Gouri Satpathy, Yogesh Tyagi and Rajinder Gupta of GGS Indraprastha Delhi University, India, said Allium is found in onions and garlic (often removed from processing and canning food) can eliminate toxic elements from contaminated substances such as industrial wastewater. When using Allium to extract heavy metals, extraction efficiency reaches 70%, especially the maximum extractability can be achieved for lead, one of the most annoying metals polluting the environment.

The team concludes that this technique is feasible and can be applied on an industrial scale, so it can provide an affordable and environmentally friendly technology for large-scale industries. Small and medium in developing countries.
