Perchlorate contamination in water is of concern because of uncertainties about toxicity and health effects, impact on ecosystems, and possible indirect exposure pathways to humans. Therefore, it is very important to investigate the ecotoxicology of perchlorate and to screen plant species for phytoremediation. Effects of perchlorate (20, 200, and 500 mg/L) on the growth of four wetland plants (Eichhornia crassipes, Acorus calamus L., Thalia dealbata, and Canna indica) as well as its… 
Effects of Perchlorate Stress on Growth and Physiological Characteristics of Rice (Oryza sativa L.) Seedlings
The results suggest that perchlorate could induce oxidative stress and oxidative damage may be the main cause of physiological damage and growth inhibition in rice plants under per chlorate stress.
Uptake, Accumulation, Translocation, and Subcellular Distribution of Perchlorate in Tea (Camellia sinensis L.) Plants.
The uptake, accumulation, and translocation of perchlorate in a tea plant-hydroponic solution system were investigated and the mechanism was further lucubrated by subcellular distribution to improve the understanding of the behavior of per chlorate in higher plants.
Removal of perchlorate by a lab-scale constructed wetland using achira (Canna indica L.)
Achira ( Canna indica L.) has not yet been tested for its potential in removing perchlorate (ClO 4 − ) from wastewater. In this study, constructed wetlands with and without achira were used to
Perchlorate Contamination: Sources, Effects, and Technologies for Remediation.
Microbial degradation is cost-effective, simple to implement, and environmentally friendly, rendering it a viable method for alleviating perchlorate pollution in the environment.
Varietal differences in the growth of rice seedlings exposed to perchlorate and their antioxidative defense mechanisms
The results indicated that gannuoxiang has higher activities of antioxidant enzymes than IR65598-112-2 to cope with oxidative damage caused by ClO4 (-) stress, which may be the main cause of its high tolerance.
Differential responses of two rice varieties to perchlorate stress
Two rice varieties, one perchlorate-tolerant (Gannuoxiang, GN) and the other perchlorate-sensitive (IR65598-112-2, IR), were exposed to 20, 200, and 400 mg/kg soil perchlorate to investigate their
Effects of perchlorate bioaccumulation on Spodoptera litura growth and sex ratio
These effects were observed at concentrations reported in natural environments contaminated with ClO4−, suggesting that this contaminant may pose a threat to the normal development and growth of this insect species.
Phytoscreening for perchlorate: rapid analysis of tree sap
Perchlorate presents an environmental health risk due to its widespread use, high solubility in water, and ability to interfere with thyroid function in humans. Delineating plumes of mobile
Review on Fate, Toxicity, and Remediation of Perchlorate
Several issues regarding the adverse impacts of the chemical—perchlorate—have been identified recently. Perchlorate is a persistent chemical, and remains in water and soil, thereby accumulating in


Phytotransformations of Perchlorate Contaminated Waters
The distribution of perchlorate and its products indicate that the transformation reaction occurred in each tissue independently of the other and accumulation of byproducts was significantly higher in leaves than in roots or stem and suggesting that these plant species show potential for phytoremediation.
Perchlorate accumulation in forage and edible vegetation.
Investigation of potential perchlorate uptake and distribution by a variety of forage and edible crops in both the laboratory and the field highlighted the potential for per chlorate exposure by routes other than drinking water.
Chapter 2 Uptake and Fate of Perchlorate in Higher Plants
Plant-mediated transformation of perchlorate into chloride
The decontamination of perchlorate-contaminated water by woody plants was investigated in sand and hydroponic bioreactors. Willow trees were found to be the most favorable woody plants with
Uptake of perchlorate in terrestrial plants.
Effect of Perchlorate on Rice Eco-physiological Characteristics and It′s Distribution in the Paddy Field System
A rice culture pot experiment was conducted to study the effects of different concentrations of perchlorate in irrigation water on the growth and physiological activities of rice. The distribution of
Accumulation of perchlorate in tobacco plants: development of a plant kinetic model.
T tobacco plants were shown to effectively accumulate perchlorate over a wide range of initial concentrations from the hydroponics solution, suggesting that plants are potential plants for the phytoremediation of per chlorate.
Evidence of perchlorate (ClO4-) reduction in plant tissues (poplar tree) using radio-labeled 36ClO4-.
Results provide evidence of perchlorate reduction inside poplar tree tissues and show that 36ClO4- is partially reduced to 36Cl3, 36Cl2, and 36Cl-.
Determination of perchlorate in tobacco plants and tobacco products.
Preliminary investigations on the occurrence of perchlorate in tobacco plants grown in soils amended with a fertilizer whose nitrogen content is derived from naturally occurring sodium nitrate (Chile saltpeter) show that per chlorate is accumulated by tobacco plants into the leaves from soils amend with fertilizers that contain perchlorates.
Accumulation of perchlorate in aquatic and terrestrial plants at a field scale.
This study examined uptake of ClO(-)(4) in smartweed and watercress as well as more than forty trees from multiple streams surrounding a perchlorate-contaminated site, indicating a large potential for ClO-(4) accumulation in aquatic and terrestrial plants.
