The study looked at the levels of lead (Pb) and cadmium (Cd) in vegetables and soil near a mining area in southern Hunan, China. They found that the soil was heavily contaminated with Pb and Cd, exceeding safe levels for vegetable growth. Vegetables grown in this soil had high levels of Pb and Cd, especially leafy vegetables. The highest levels were found in garlic and three-colored amaranth. This contamination poses a serious health risk to people consuming these vegetables. Leafy vegetables tended to accumulate more heavy metals than fruits.
