Heavy metal (HM) poisoning of agricultural soils poses a serious risk to plant life, human health, and the global food supply. When HM levels in get dangerous levels, it harms crop health yield. Chromium (Cr), arsenic (As), nickel (Ni), cadmium (Cd), lead (Pb), mercury (Hg), zinc (Zn), copper (Cu) are main heavy metals. The environment contains these metals varying degrees, such as soil, food, water, even air. These substances damage plants alter soil characteristics, which lowers Crop types, growing circumstances, elemental toxicity, developmental stage, physical chemical properties, presence bioavailability (HMs) solution some factors affecting amount toxicity crops. By interfering with normal structure function cellular components, HMs can impede various metabolic processes. Humans exposed numerous diseases by consuming affected products. Exposure certain harm kidneys, brain, intestines, lungs, liver, other organs body. This review assesses (1) contamination through different sources, like anthropogenic natural; (2) effect on microorganisms properties soil; (3) well production; (4) entering chain associated hazards health. Lastly, we identified research gaps suggested further study. If people want feel safe their surroundings, there needs be stringent regulation release into environment.

Pb uptake, accumulation, and translocation in plants: Plant physiological, biochemical, and molecular response: A review

Heliyon, Journal Year: 2024, Volume and Issue: 10(6), P. e27724 - e27724

Lead (Pb) is a highly toxic contaminant that ubiquitously present in the ecosystem and poses severe environmental issues, including hazards to soil-plant systems. This review focuses on uptake, accumulation, translocation of Pb metallic ions their toxicological effects plant morpho-physiological biochemical attributes. We highlight uptake metal controlled by cation exchange capacity, pH, size soil particles, root nature, other physio-chemical limitations. toxicity obstructs seed germination, root/shoot length, growth, final crop-yield. disrupts nutrient through roots, alters plasma membrane permeability, disturbs chloroplast ultrastructure triggers changes respiration as well transpiration activities, creates reactive oxygen species (ROS), activates some enzymatic non-enzymatic antioxidants. also impairs photosynthesis, water balance mineral nutrients, hormonal status, structure permeability. provides consolidated information concentrating current studies associated with Pb-induced oxidative stress conditions various plants, highlighting roles different antioxidants plants mitigating Pb-stress. Additionally, we discussed detoxification tolerance responses regulating gene expressions, protein, glutathione metabolisms resist phytotoxicity. Overall, approaches tackle have been addressed; phytoremediation techniques biochar amendments are economical eco-friendly remedies for improving Pb-contaminated soils.
