Journal ArticleDOI
Chromium speciation, bioavailability, uptake, toxicity and detoxification in soil-plant system: A review.
Muhammad Shahid,Saliha Shamshad,Marina Rafiq,Sana Khalid,Irshad Bibi,Nabeel Khan Niazi,Camille Dumat,Muhammad Rashid +7 more
TL;DR: There is a dire need to monitor biogeochemical behavior of Cr in soil-plant system, as Chromium induces phytotoxicity by interfering plant growth, nutrient uptake and photosynthesis, inducing enhanced generation of reactive oxygen species, causing lipid peroxidation and altering the antioxidant activities.
Book ChapterDOI
Arsenic Behaviour in Soil-Plant System: Biogeochemical Reactions and Chemical Speciation Influences
Sana Khalid,Muhammad Shahid,Nabeel Khan Niazi,Marina Rafiq,Hafiz Faiq Bakhat,Muhammad Imran,Tauqeer Abbas,Irshad Bibi,Camille Dumat +8 more
TL;DR: In this article, the authors established a link between As speciation and biogeochemical behaviour of As in complex soil-plant systems, and highlighted how the chemical speciation of As affects its bio-ochemical behaviour (adsorption/desorption, mobility, bioavailability/phytoavailability) in soil plant system.
Journal ArticleDOI
Comparative effect of calcium and EDTA on arsenic uptake and physiological attributes of Pisum sativum
Marina Rafiq,Muhammad Shahid,Ghulam Abbas,Saliha Shamshad,Sana Khalid,Nabeel Khan Niazi,Camille Dumat +6 more
TL;DR: Due to possible precipitation of Ca-As compounds, the soils with higher levels of Ca ions are likely to be less prone to food chain contamination.
Journal ArticleDOI
A comparative study to evaluate efficiency of EDTA and calcium in alleviating arsenic toxicity to germinating and young Vicia faba L. seedlings
Marina Rafiq,Muhammad Shahid,Saliha Shamshad,Sana Khalid,Nabeel Khan Niazi,Nabeel Khan Niazi,Nabeel Khan Niazi,Ghulam Abbas,Muhammad Saeed,Mazhar Ali,Behzad Murtaza +10 more
TL;DR: In this article, the effect of calcium (Ca) and ethylenediaminetetraacetic acid (EDTA) addition on arsenic (As) accumulation and physiological attributes of Vicia faba L. was investigated.
Journal ArticleDOI
Arsenic accumulation and physiological attributes of spinach in the presence of amendments: an implication to reduce health risk.
Muhammad Shahid,Marina Rafiq,Nabeel Khan Niazi,Nabeel Khan Niazi,Nabeel Khan Niazi,Camille Dumat,Saliha Shamshad,Sana Khalid,Irshad Bibi,Irshad Bibi +9 more
TL;DR: Higher levels of Ca were more effective in reducing As uptake and toxicity as well as enhancing chlorophyll contents as well As contents in roots and shoots, hydrogen peroxide production, chlorophyLL contents, and lipid peroxidation.
