Rhodizonic acid disodium (Sodium rhodizonate dibasic) is a transition metal-dependent pro-oxidant and lead detection agent that induces reactive oxygen species generation, DNA damage, and inhibits Aconitase activity. Rhodizonic acid disodium generates superoxide anion radicals in an iron (II)-dependent manner, leading to aconitase inactivation. Rhodizonic acid disodium also triggers hydroxyl radical-mediated DNA strand breaks and 8-OHdG formation via copper ion reduction. Rhodizonic acid disodium reacts with lead to form a scarlet precipitate, with the color intensity proportional to lead content, enabling qualitative or quantitative analysis of lead. Rhodizonic acid disodium can also be used for real-time visualization of the dynamic process of lead sequestration in the plant rhizosphere and evaluation of the effects of environmental factors such as soil type on the stability of lead-sequestering structures .

Rhodizonic acid disodium (Sodium rhodizonate dibasic) is a transition metal-dependent pro-oxidant and lead detection agent that induces reactive oxygen species generation, DNA damage, and inhibits Aconitase activity. Rhodizonic acid disodium generates superoxide anion radicals in an iron (II)-dependent manner, leading to aconitase inactivation. Rhodizonic acid disodium also triggers hydroxyl radical-mediated DNA strand breaks and 8-OHdG formation via copper ion reduction. Rhodizonic acid disodium reacts with lead to form a scarlet precipitate, with the color intensity proportional to lead content, enabling qualitative or quantitative analysis of lead. Rhodizonic acid disodium can also be used for real-time visualization of the dynamic process of lead sequestration in the plant rhizosphere and evaluation of the effects of environmental factors such as soil type on the stability of lead-sequestering structures .
