Impact of coal dust handling on mangrove ecosystem around Kandla Port, Gujarat, India.

Krupa H. Jha, Nischal Joshi


The present study aims to identify the impacts of port-led coal activities on mangroves and its ecosystem. Duration of the study was 6 months. Study was conducted at two different locations viz. Kandla Port and the Vadinar site which was selected as pristine located in Marine National Park. To identify the coal impact, soil and water samples were assessed as per the CPCB standards which included heavy metal assessment also. Samples collected from 3 different locations with 0-3 km radius from the Port. For assessing, mangrove health, Dust load assessment in leaf, Carbon content estimation in leaf, Relative leaf water content, Chlorophyll, Stomata density and morphological observation were also recorded. To identify the impacts of coal dust on mangrove, obtained the holistic approach by studying not only mangrove physiology but the physicochemical indicators (soil & water) and heavy metal assessment too. Results of soil and water samples’ analysis revealed that the samples collected around Kandla Port showed highest variation in the physicochemical properties of soil and water. Heavy metal contamination was observed in all sample sites including pristine location too. However, Physicochemical analysis of soil and water carried out for the mangrove ecosystem showed contamination of different types but only correlating it with coal as its major source cannot be established since there are various other development activities taking placed around the Port which could have contributed to the pollution.
