Faster, Simpler, More Sensitive Test for Toxic Heavy Metals in Foods and Water (VIDEO)
Caption
Finding out if the food and water we consume are safe from toxic and carcinogenic metals can now be much faster and simpler. Researchers at the University Johannesburg developed an efficient and sensitive method to test for dangerous levels of heavy metals, like arsenic, cadmium, chromium and lead in vegetables and water. It is possible to test for several metals at the same time, and automation can be added. The method can be used to test other foods also.
