| Abstract | This work evaluated the response of two saltmarsh plants, Juncus maritimus and Phragmites australis, to short- and long-term exposure to sediment contaminated with Cd.Plants (including roots and associated sediment) were placed in vessels in a greenhouse with tidal simulation. Vessels were spiked with Cd, with Cd solution in contact with the sediment/root plant system for 6 h. Half of the vessels were then dismantled whereas the other set was maintained for 2 months. Short-term Cd exposure (6 h) simulated a flood situation with metal in a more bioavailable form. Long-term exposure simulated what normally happens in the field after contamination, the metal being progressively incorporated into the sediment and therefore less available.Both plants were able to take up considerable amounts of Cd in their belowground tissues in a short-time period; this accumulation increasing after 2 months. P. australis displayed short-term Cd translocation, but, for J. maritimus metal, translocation was only observed in the long-term. Both J. maritimus and P. australis have the ability to promptly respond to Cd contamination, being able to cope with Cd contamination in the long-term.Results indicate these plants can contribute to the remediation of sediment contaminated with Cd in estuarine environments, retaining metal in their belowground structures, which contributes to the recovery of moderately impacted environments. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
