Impact of Port and harbour activities on plankton distribution and dynamics: A multivariate approach.

Numerous researches have been conducted to study the impact of Port activities on water quality. However, investigation on the response of the inhabiting biota to Port related extrinsic factors is extremely limited. Using Canonical Correspondence Analysis, comprehensive assessment of plankton population dynamics and distribution corresponding to the spatial heterogeneity in physico-chemical characteristics of harbour and adjacent coastal water is conducted.

Fly ash toxicity, emerging issues and possible implications for its exploitation in agriculture; Indian scenario: A review.

Fly ash is considered as an environmental hazard worldwide, since it generally contain organic pollutants, probable toxic metals like Se, As, B, V, Al, Pb, Hg, Cr and radionuclide's Uranium, Thorium. Although fly ash contains toxic substances, it also contains most of the oxides and trace elements. Presence of oxides contributes to its alkaline pH while trace elements provides nutrients for plant growth hence, it is suggested that it can be used in low concentration in agriculture sector as well as a soil conditioner as fly ash improves the physico-chemical and biological properties of contaminated soils.
