The ever-growing shadow of pollution is dimming crop yields worldwide. Arsenic, a potent environmental toxin, poses a particular threat, silently infiltrating soil and accumulating in edible plants like okra. This not only harms plant health but also jeopardizes human well-being through contaminated food chains.

Arsenic exposure wreaks havoc on okra. It stunts growth, disrupts vital processes, and triggers oxidative stress, damaging cells from within. This silent menace threatens both food security and public health.

This study shines a light on a glimmer of hope – two readily available waste materials offer a robust defense against arsenic’s tyranny. Steel slag, a byproduct of steelmaking, and corncob biochar, generated from agricultural waste, emerge as unexpected heroes.

Both steel slag and corncob biochar possess remarkable properties that neutralize arsenic’s detrimental effects. They act as shields, absorbing and immobilizing the toxin before it can harm the plant. Additionally, they stimulate the okra’s own natural defenses, boosting the activity of antioxidant enzymes and the glyoxalase system, which effectively mop up harmful free radicals.

Okra treated with these waste-derived amendments displayed remarkable resilience. They exhibited improved growth, enhanced biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More production, and reduced oxidative stress markers. Notably, the combined application of steel slag and corncob biochar yielded the most potent defense, showcasing the synergistic power of their action.

This research paves the way for a sustainable approach to combat arsenic contamination in agriculture. By harnessing the potential of readily available waste materials, we can not only protect valuable crops but also minimize environmental impact. This win-win scenario offers a beacon of hope for a healthier future for both plants and people.
