Roughly One-Sixth of Croplands Globally Polluted With Toxic Heavy Metals, Researchers Say
Roughly one-sixth of croplands globally — 14 to 17 percent, or approximately 598 million acres — are contaminated by one or more toxic heavy metals like arsenic, cobalt, cadmium, copper, lead and nickel at levels exceeding human health and agricultural safety thresholds, a new study has found. Heavy metals are elements that come from both natural and human-made sources. They do not break down in the environment and stay in soils for decades, all…
Scientists warn that approximately 15% of the world's agricultural land is polluted with dangerous heavy metals such as arsenic, lead and cadmium. Studies show that up to 1.4 billion people live in high-risk areas, where these substances end up in food and water, affecting health and the environment.
According to a study published in the journal Science, between 900 million and 1.4 billion individuals worldwide could be exposed to a high level of at least one toxic metal.
About a sixth of global cropland likely polluted with toxic metals: Study
Up to 17 percent of the planet’s agricultural land may be contaminated by toxic heavy metals, a new study has found. As many as 1.4 billion people reside in areas with soil dangerously polluted with compounds like arsenic, cadmium, cobalt, chromium, copper, nickel and lead, according to the study, published in Science. Toxic heavy metal pollution…
Substances can be toxic to humans, animals, and plants at different doses and spread to different ecosystems through food chains and water. Up to 17% of the world's arable land is contaminated with at least one type of toxic heavy metal, posing health risks to up to 1.4 billion people, scientists warned on Thursday. The research, published in the journal Science, is the first of its kind to evaluate a global view of soil contamination by heavy m…
