Lead uptake, toxicity, and detoxification in plants
The negative effects that lead has on plant vegetative growth mainly result from the following factors: distortion of chloroplast ultrastructure, obstructed electron transport,inhibition of Calvin cycle enzymes, impaired uptake of essential elements, such as Mg and Fe, and induced deficiency of CO2 resulting from stomatal closureUnder lead stress, plants possess several defense strategies to cope with lead toxicity Effects of lead on biochemical properties of plants Like different heavy metals, lead treatment also affects the activity of a wide range of enzymes of different metabolic pathways Chloramphenicol acetyl tranferase (CAT) is oxidoreductase that decomposes H 2 O 2 The effect of lead on plants in terms of growing and Genotoxic Effect of Lead on Crop Plants Lead induces a decrease in mitotic activity and shortens the mitotic stage and prolongs interphase, thus increasing the period of cell cycle (Patra et al, 2004) because lead is able to enter the nucleus and bind directly to the DNA or indirectly to protein (Małecka et al, 2008) After binding to DNA, lead disrupts DNA repair and replication mechanismsEffect of Lead on Plant and Human DNA Damages
How Does Lead Affect Our Environment? The Green
The Impact Lead Has on Plants Plants have evolved to cope with the naturally low level of lead in the soil However, they are not going to thrive in an area where mining tailings and buried leadacid batteries pollute the soil with lead Lead in the soil Heavy metal toxicity, defined as the ratio of heavy metal to calcium in the ammonium acetatesoluble soil extract, gives a better indication of the sensitivity of plants to the toxic effects of lead and zinc than do the actual metal concentrations present in the soil, particularly in the case of lead Highly leadtolerant plants, such as the metallophytes Armeria maritima and Silene vulgaris, occur on soils in which the molar ratio of lead The effects of lead and zinc on the distribution of In addition to direct toxic effects on plants, lead can indirectly affect a variety of plants At concentrations of 10000‑40000 mg/kg, lead can kill soil bacteria and fungi This in turn negatively affects the growth of many plants and inhibits organic matter decomposition Lead in plants and soil Plantprobs
Effect of Heavy Metals on Plants: An Overview

Effects of lead stress on the growth, physiology, and
In this study, we investigated the effects of different lead (Pb) concentrations (0, 200, 600, 1000, 1400 mg kg1 soil) on the growth, ion enrichment in the tissues, photosynthetic and physiological characteristics, and cellular structures of privet seedlings We observed that with the increase in the concentrations of Pb, the growth of privet seedlings was restricted, and the level of Pb ion The effects of soil pH and a prior waterlogging treatment on the uptake of copper, lead and arsenic by radish and silver beet were investigated in a glasshouse experiment Eight soils were compared, two of which were former orchard soils, two existing orchard soils, two dosed with copper, lead and arsenic, and two affected either by mining or by orebody mineralisationThe effects of soil contamination with copper, lead Mining remains an essential and growing part of the modern industry By some estimates, it makes up nearly 45% of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world However, many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environmentThe Environmental Impact of Mining (Different Mining

Lead toxicity in plants SciELO
Lead tolerance in plants: The two basic strategies of metal uptake related to tolerance in plants, as suggested by Baker (1981), involve (i) the 'excluder' strategy in which the concentration of heavy metals is maintained at a constant low level until critical soil concentration is reached when toxicity ensues and unrestricted metal transport Mining remains an essential and growing part of the modern industry By some estimates, it makes up nearly 45% of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world However, many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environmentThe Environmental Impact of Mining (Different Mining Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil Mining can also trigger the formation of sinkholes The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining siteWhat Is The Environmental Impact Of The Mining Industry
