The study looked at how heavy metals like zinc and cadmium affect mung bean plants. The researchers wanted to see how these metals change the plant's growth and protein levels. They found that cadmium had a bigger impact on the plants than zinc. At low metal levels, the plants' chemical levels went up, but at higher levels, they dropped. They also discovered a specific protein in the stressed plants that might help them deal with the metal stress. Overall, the study suggests that we need to start thinking about how to handle these metal problems now to have a healthier future.
