The alleviation of lead toxicity in Vicia faba L. by the application of selenium
Selenium (Se) is an essential element for humans but is not considered as essential for plants. However, its beneficial role in improving plant growth and stress tolerances is well established. In order to study the role of Se in lead (Pb) toxicity in Faba bean (Vicia faba L.).This experiment was carried out on plants grown […]
Evaluation of lead toxicity in maize (Zea mays L.) as influenced by organic and inorganic sources of nitrogen
Number of human health risks and environmental degradation is associated with lead toxicity. It is imperative to examine and underpin sound solutions. There fore, present study was undertaken at Agronomic Research Area, University of Agriculture, Faisalabad with aim to investigate the effect of lead toxicity in maize (Zea mays L.) as influenced by organic and […]
Effect of heavy metals (copper, zinc, cadmium and lead) on the accumulation of proline and soluble sugars in Atriplex canescens (Pursh) Nutt
The Atriplex canescens is well adapted to extreme environmental conditions and present properties accumulator of heavy metals. Our study is to investigate the effect accumulator of heavy metals (copper, zinc, cadmium and lead) by the Atriplex canescenss stressed after 60 days of the sowing. It applying five different doses to the plant Atriplex canescens for two weeks for: […]
Growth and physiological responses of cereals speciesunder lead stress
Cereals are the most important staple foods for mankind worldwide and represent the main constituent of animal feed. Their toxicity depends on several factors including the dose, route of exposure, and chemical species, as well as the age, gender, genetics, and nutritional status of exposed individuals. A study was conducted to determine the effect of […]
Biosorption of lead, cadmium and iron by Sphaerotilus natans
Heavy metal contamination is potentially environmental issue and certainly a major health concern in many parts of the world, primarily due to various anthropogenic activities. The heavy metals selected for this studies that is lead, iron and cadmium have no positive role in living systems. All these heavy metals are highly toxic. The biosorption by […]
Absorption capacity of lead by different lichenic species
The use of bioindicator is very important for assessing the pollution intensity by accumulation of pollutants and lead in particular. The measurement of this accumulation in some organisms such as lichens and its effects on the physiological and morphological characteristics was found very effective to answer this problem. It is in this context that we […]
Effect of lead on plant growth, lead accumulation and biochemical changes of Pistia stratiotes L.
Aquatic macrophytes are well known accumulators for heavy metals in contaminated water bodies. The objective of this study was to evaluate the effect of lead nitrate on the growth, accumulation and biochemical changes of Pistia stratiotes L. Plants were cultured in Hoagland’s medium which was exposed to different concentrations (10, 20, 30, 40, 50, 60, […]
Use of Ornamental Plant, “Vinca” (Vinca rosea L.) for Remediation of Lead-contaminated soil
Phytoremediation potential of an ornamental plant, Vinca (Vinca rosea) was assessed for Lead- contaminated soil. Plants were grown in pots having soils with different levels of Pb contamination i.e. T1 (10 ppm), T2 (20 ppm), T3 (30 ppm), T4 (40 ppm), T5 (50 ppm), T6 (60 ppm), T7 (70 ppm), T8 (80 ppm) and T9 […]
Public health implications of heavy metal contamination of plants growing in the lead- zinc mining area of Ishiagu, Nigeria
The study assessed heavy metal content of plants growing in a lead-zinc mining pit in Ishiagu, Nigeria. Random sampling, involving a lucky dip without replacement was used to select twelve plants from thirty four identified in the mining pit, using a sampling ratio of 1 in 3. Metal content of plants followed the sequence; Zn […]
