Metal Accumulation in Carrots, Soil, and Irrigation Water Samples

The study analyzed metal accumulation in carrots, soil, and irrigating water from Loc Thanh village, Vietnam. It found that soil samples were low in nutrients but had higher pH, Al 3+, and Fe 3+ levels than standards. Water samples lacked toxic heavy metals like As, Pb, and Cd, but had elevated Cu, Zn, and Fe levels. Carrot samples exceeded allowable levels for As, Pb, Cu, and Zn, with lower lipid and protein content, though NO3- was within standards. However, carrots grown using organic methods had lower heavy metal levels, suggesting the importance of selecting appropriate soil, water, and organic methods for safe, high-quality carrot production.
