Ecology and Environment

This study by National Environmental Engineering Research Institute published in Current Science was carried out to identify Pteris vitta and test its hyper-accumulating properties. The plant is commonly known as the Ladder brake fern or Chinese brake fern plant in India, and had been reported elsewhere as an arsenic hyper-accumulator.

.The remediation of arsenic and chromium contaminated soil and water has become an important environmental issue. It is in this context that the discovery of hyper-accumulator plant species, which have the unusual ability of accumulating metals such as arsenic (As), chromium (Cr), zinc (Zn), nickel (Ni) and copper (Cu) to very high concentrations, has further boosted technologies based on this property.

This is the first report of characterization of arsenic accumulation in an Indian ecotype (plant), which also shows chromium hyperaccumulation in addition to arsenic. Intact plantlets were grown in 20 per cent Hoagland solution amended with up to 200 mg arsenic or chromium medium. Plants absorbed and accumulated a significant amount of arsenic and chromium in their biomass with high bio-enrichment factor. Arsenic and chromium tolerance by spores and gametophytes under in-vitro was also assessed.

The fundamental right to water in rural areas is well-established in India, but the actual content of this right has not been elaborated upon in judicial decisions. There is no general drinking water legislation that would provide this missing content.

These two reports discuss the dependency of agriculture on phosphorous and the ways to mitigate the problem.

The first report looks at agricultural dependence of chemical nutrients on a global scale and even discusses the potential international political fallout of a reduction in phosphorous. The second report is focused on ways to tackle the dependency on this mineral, in the Indian context. However, both speak of the need for finding alternatives to the current methods of obtaining phosphorous, which is largely through mining.
