Lead Uptake, Toxicity, and Detoxification in Plants

2011-4-25  Among common pollutants that affect plants, lead is among the most toxic and frequently encountered (Cecchi et al. 2008; Grover et al. 2010; Shahid et al. 2011). Lead continues to be used widely in many industrial processes and occurs as a contaminant in all environmental compartments (soils, water, the atmosphere, and living organisms).

Salinity-induced alterations in plant growth, antioxidant

2019-5-22  Lead (Pb) was selected as the representative heavy metal, and NaCl was added to simulate the Pb-polluted saline soil. The results showed that 0.5% NaCl addition alleviated the inhibition of plant growth under moderate Pb stress (35 and 100 mg kg−1 Pb levels), while the phytotoxicity on plants was magnified by 1.0% NaCl addition.

What is worrying is that in both our earlier studies [19] and in the present trials, magnesium fertilization in any of the tested technologies did not lead to an increase in the concentration of this nutrient in tubers.

CDC Lead At Risk Populations Pregnant Women

Elevated levels of lead in the blood during pregnancy can: Increase risk for miscarriage. Cause the baby to be born too early or too small. Hurt the baby’s brain, kidneys, and nervous system. Cause the child to have learning or behavior problems. If you are pregnant and think you may have been exposed to lead, talk to your healthcare provider

Salicylic acid alleviates decreases in BMC Plant Biology

2010-2-23  Background Although the effect of salicylic acid (SA) on photosynthesis of plants including grapevines has been investigated, very little is yet known about the effects of SA on carbon assimilation and several components of PSII electron transport (donor side, reaction center and acceptor side). In this study, the impact of SA pretreatment on photosynthesis was evaluated in the leaves of young

Cleaner Power Plants US EPA

2020-10-23  There are about 1,400 coal- and oil-fired electric generating units (EGUs) at 600 power plants covered by these standards.They emit harmful pollutants, including mercury, non-mercury metallic toxics, acid gases, and organic air toxics such as dioxin.

2021-7-21  German lead producer Berzelius Stolberg has declared force majeure on metal shipments from its Stolberg smelter in western Germany after floods hit

Reactive Oxygen Species, Oxidative Damage, and

Reactive oxygen species (ROS) are produced as a normal product of plant cellular metabolism. Various environmental stresses lead to excessive production of ROS causing progressive oxidative damage and ultimately cell death. Despite their destructive activity, they are well-described second messengers in a variety of cellular processes, including conferment of tolerance to various environmental

Plant architectural responses in simultaneous maize

2020-5-21  Crop plants show plastic responses in plant architecture to their growing conditions to forage for light and avoid shading. There is little knowledge on plant architectural responses to growing conditions in simultaneous (non-relay) intercropping and their relationship to species yields.
