Intrinsyx Environmental was contracted to implement its phytoremediation solutions at a former manufacturing facility with very high concentrations of TCE, DCE, and vinyl chloride. Intrinsyx performed a site assessment and came up with a systems design of strategic planting locations to exert hydrological control over the plume. ...
The site was a petroleum tank farm from the early half of the 20th century. Contaminants on-site include petroleum hydrocarbons, benzene and ethylbenzene, and PAHs naphthalene and 2-methylnapthalene. Most contaminants are in subsurface and groundwater, with the exception of PAHs that extend from the surface to ...
The phytoremediation program will offer free assessments to eligible Tree City USA communities with contaminated areas. Through this assessment, municipal employees in community development and public works can determine whether their city or town will be a good fit for cleaning their contaminated areas through phytoremediation. If deemed suitable, Arbor Day ...
The Arbor Day Foundation and Intrinsyx Environmental have announced a partnership to launch a phytoremediation program to use trees and plants to clean up contaminated land in cities and towns. ...
There is a possibility to create a sustainable method of biomass growth in mid-low contaminated sites soil system using phytoremedial methods in biomass engineering. Main aim of the research was to assess herbaceous plants abilities of clean the soil contaminated by oil hydrocarbons. ...

This article discusses the environmental concerns regarding soil contamination by heavy metals and the possibility of growing a high biomass-yielding crop (i.e., rapeseed) as a tool of phytoremediation. The aim of our research was to investigate the growth parameters and the capacity of rapeseed to accumulate Cd, Cu, and Zn from the contaminated soil and to investigate the effects of the chelants ...

Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a fungus, ...
The half-life of chlorpyrifos was shortened in the hydroponic system with plants, indicating that I. pseudacorus accelerated chlorpyrifos removal from water. But the contribution of the plant to chlorpyrifos removal in the hydroponic phytoremediation system decreased with the increase of initial concentration of chlorpyrifos. The results also ...
The aim of the present investigation is to develop a suitable phytoremediation technology for the procumbent removal of chromium(VI) in tannery wastewater. Water hyacinth species, Eichhornia crassipes, was chosen to remediate chromium from synthetic wastewater. Present study revealed 88% Cr(VI) removal in synthetic wastewater sample within 48 hours of the study at all concentrations ranging from ...
Contaminated (TPHs and heavy metals) dredged sediments from Livorno port (Italy) were biological treated using plants and earthworms. Sediments presented an asphyctic physical structure owing to the silt?clay granulometric composition, a high salty level and a low organic content. A meso-scale experiment was done utilising three different bioremediation treatments: a) plants (Paspalum vaginatum ...
High Rate Transpiration System (HRTS) is a well-designed land treatment system composed of ridges and furrows and well-controlled hydraulic loading of wastewater. ...
Since the initiation of the industrial age with its parallel reliance on the utilisation of the hydrocarbon reserves on earth, the biosphere has been increasingly exposed to an ever expanding chemical variety of anthropogenic origin. Phytoremediation is an environmental technology for the cleaning of polluted soils using plants that needs the knowledge about transport and fate of pollutants for ...
High concentrations of cadmium in soils represent a potential threat to human health because it is incorporated in the food chain mainly by plant uptake. The behaviour of cadmium in soils depends on several factors related to both soil and plant characteristics. This paper provides an overview of such factors as well as of the most environmentally friendly in situ soil remediation techniques in ...
Phytoremediation is a promising technology for the clean-up of petroleum-contaminated soils, especially in the tropics where climatic conditions favour plant growth and microbial activity and where financial resources can be limited. The objective of this work was to identify tropical plant species from the eastern savannahs of Venezuela suitable for this technology. Three legumes (Calopogonium ...
These hydrologic and geochemical data demonstrate the J-Field site provides ideal hydrogeologic conditions for the successful application of phytoremediation. J-Field is underlain by a low permeability, shallow water table aquifer that discharges to a biologically active freshwater marsh. Based on the favorable results of the pilot study, 600 additional trees are being planted to ...
