  journal={Environmental Chemistry Letters},
Metal contamination issues are becoming increasingly common in India and elsewhere, with many documented cases of metal toxicity in mining industries, foundries, smelters, coal-burning power plants and agriculture. Heavy metals, such as cadmium, copper, lead, chromium and mercury are major environmental pollutants, particularly in areas with high anthropogenic pressure. Heavy metal accumulation in soils is of concern in agricultural production due to the adverse effects on food safety and… 

Mechanisms of Heavy Metal Toxicity in Plants

Pollution of the environment with the toxic heavy metals has become one of the major causes for worry for human health in both emerging and advanced countries. Metal contamination issues are becoming

A review of heavy metals accumulation pathways, sources and management in soils

One of the foremost issues for the current society is heavy metal pollution which is caused owing to recent extraordinary urbanization and industrialization. The impact of metal contamination on the

Agroecological Responses of Heavy Metal Pollution with Special Emphasis on Soil Health and Plant Performances

Following the modern-day urbanization and industrialization, heavy metal contamination has become a prime concern for today’s society. Starting from the agricultural soil in our food basket these

Heavy metals and its impact in vegetable crops

Environmental pollution is rapidly booming worldwide. The soil contaminated with heavy metals like lead Cr, Mn, Fe, Ni, Cu, Zn, Cd, Pb and Hg has serious environmental problems since these metals are

Role of Iron in Alleviating Heavy Metal Stress

Heavy metals naturally present in soils usually result from human activities such as agricultural practices, mining, automobile, sewage processing, and metal industries. Higher concentrations of

Potential of Biochar for the Remediation of Heavy Metal Contaminated Soil

Soil contamination with heavy metals has become a serious concern. Due to their non degradable nature, speciation and bioavailability to the living organisms, heavy metals are prone to enter the food

Physiological, Biochemical Changes, and Phytotoxicity Remediation in Agricultural Plant Species Cultivated in Soils Contaminated with Copper and Zinc

Most heavy metals are found naturally in the earth’s crust at concentrations that do not cause toxicity to living beings. However, since the industrial revolution, heavy metal pollution has increased

Silicon Potential to Mitigate Plant Heavy Metals Stress for Sustainable Agriculture: a Review

In recent decades, environmental pollution due to presence of toxic metal elements come across globally with severe threats to plants, soil, humans, and animals. The major causes behind this are

Cadmium toxicity and phytoremediation in trees - A review

Over time, the anthropic activity has contributed to alter biogeochemical cycle of heavy metals by releasing contaminants into water, soil and air. Due to contamination of environments with heavy

Mycoremediation Mechanisms for Heavy Metal Resistance/Tolerance in Plants

Environmental pollution is an ever-increasing problem being faced by the world in the present era. Soil pollution is increasing, owing to dumping of all kinds of wastes, mining and using of



Biochemical, physiological, and structural effects of excess copper in plants

Copper effects on plant physiology are wide ranging, including interference with fatty acid and protein metabolism and inhibition of respiration and nitrogen fixation processes, and at the whole plant level Cu is an effective inhibitor of vegetative growth and induces general symptoms of senescence.

Heavy metals incidence in the application of inorganic fertilizers and pesticides to rice farming soils.

Phytoremediation: A Novel Strategy for the Removal of Toxic Metals from the Environment Using Plants

Biological mechanisms of toxic metal uptake, translocation and resistance as well as strategies for improving phytoremediation are also discussed.

Iron toxicity in rice—conditions and management concepts

Iron toxicity is a syndrome of disorder associated with large concentrations of reduced iron (Fe2+) in the soil solution. It only occurs in flooded soils and hence affects primarily the production of

Phytoaccumulation of heavy metals by aquatic plants.

Heavy Metal Contents in Vegetables and Market Garden Soils in Hong Kong

Urbanization is one of the major causes of soil pollution of many market garden soils in various municipalities. The aim of this project was to monitor the heavy metal contents in market garden soils

Impact of soil properties on critical concentrations of cadmium, lead, copper, zinc, and mercury in soil and soil solution in view of ecotoxicological effects.

This chapter presents an overview of methodologies used to derive critical (i) reactive and total metal concentrations in soils and (ii) free metal ion and totalMetal concentrations in soil solution for Cd, Pb, Cu, Zn, and Hg, taking into account the effect of soil properties related to ecotoxicological effects.

Toxicity of Zinc and Copper to Brassica Species: Implications for Phytoremediation

Heavy metal-induced inhibition of Fe and Mn accumulation may have been a significant factor in reducing plant growth and the extent of Zn and Cu removal was reduced in the presence of both metals, as compared to the single heavy metal treatments.
