Phytoremediation: Using native vegetation to stabilise heavy metal contaminants at polluted sites

Written by

Madeleine Günthardt-Goerg and Pierre Vollenweider are researching how the properties of trees can be used to develop sustainable management strategies to phyto-stabilise contamination at metal-polluted sites through phytoremediation.

Elevated concentrations of heavy metals at polluted sites represent serious human health hazards and environmental threats. Persistent metal pollution is hard to remedy but one possible and effective method is phytoremediation, using plants to stabilise the metal pollution and ameliorate the contaminated soil properties. Across 20 years of research, Drs Madeleine Günthardt-Goerg and Pierre Vollenweider of the Swiss Federal Institute […]

Symbiotically competent cyanobacteria for the bio-sustainable cultivation of rice

Written by

The researchers tested the interactions of several Nostoc strains in laboratory conditions.

Every year, large amounts of nitrogen fertilisers are used around the world to sustain the cultivation of rice. The wetland culture conditions required for rice cause nitrogen to leach and contaminate freshwater, triggering a number of adverse consequences for aquatic habitats. Dr Consolación Álvarez and Dr Vicente Mariscal Romero, from the Spanish National Research Council (CSIC), Spain, propose the development […]
