Heavy Metal, Soils, Contamination, Phytoremediation 1. Introduction Heavy metals are the major environmental contaminants and pose a severe threat to human and animal health by their long-term persistence in the environment 1]. The remediation of soils contaminated by heavy metals is a [cost-intensive and technically complex procedure 2]-[5]. Phytoremediation is a fast developing field, since last ten years lot of field application were initiated all over the world, it includes Phytoremediation of Organic, Inorganic. A sustainable and inexpensive process, fastly emerging as a removes heavy metals by the help of plants which is a

Pistia stratiotes was examined in the presence of several distinct heavy metals separately, in order to determine the ability of the plant to tolerate and accumulate the metals tested and for eventual use for phytoremediation of waste water or natural water bodies polluted … Heavy Metal, Soils, Contamination, Phytoremediation 1.

Psoralea pinnata (up to 55%). Index Terms—Chromium, iron, phytoextraction, Psoralea pinnata. I. INTRODUCTION. Soils contamination by heavy metals and metalloids has become a serious environmental issue today. A number of metals including chromium, iron, arsenic, zinc, cadmium, mercury and copper are known to significantly compromise Heavy metals are released into atmosphere through discharge of gases and dust from transport and production of constructed material and energy. In atmosphere, heavy metals exist in the form of aerosols and then through precipitation become deposit to soil (Aksu, 2015, Naderizadeh et al., 2016, Suvarapu and Baek, 2017).

Accumulation of heavy metals and uptake in dry biomass Aquatic plants are well known to accumulate metals from contaminated water and substrates (Rai et al. 1995). Denny (1980) reported that heavy metals were taken up by plants by absorption and translocation, and released by excretion. Highlights Heavy metal pollution is a serious environmental problem. Phytoremediation is a better option for cleanup of metal-contaminated sites. Phytoremediation is a green technology with good public perception. Research is in progress to screen plants for hyperaccumulation of heavy metals. Advancement in molecular studies will improve efficiency of phytoremediation.

Introduction. Heavy metals and other organic compounds constitutes the major environmental contaminants, and the trials of phytoremediation to free pollutants from waste water and contaminated soil dates back to hundreds of years ago in plants such as the Thlaspi caerulescens and Viola calaminaria, which were reported to remediate high concentration of heavy metals [].

Toxic heavy metals and organic pollutants are the major targets for phytoremediation. In recent years, knowledge of the physiological and molecular mechanisms of phytoremediation began to emerge together with biological and engineering strategies designed to optimize and improve phytoremediation. Phytoremediation of heavy metals by Trifolium alexandrinum Hazrat Ali, Muhammad Naseer and Muhammad Anwar Sajad International Journal of Environmental Sciences Volume 2 No.3, 2012 1461 technology is interdisciplinary in nature and requires input of …

Phytoremediation uses wild or genetically modified plants (GMPs) to extract a wide range of heavy metals and organic pollutants from the soil. Initial experiments with transgenic plants have shown that they are indeed efficient in drawing metals from heavily contaminated soils. Heavy metals in soil-pollution The term “heavy metal” refers to those metals of the periodic tables whose specific weight is greater than 5g.cm3 or have an atomic number above 20, generally excluding alkali and alkaline earth elements.5 The term is somewhat imprecise when taking into account
