The study is carried out to understand the impact of the land-use change in terms of alteration in flow regimes, which are understood to be a leading cause of ecological and environmental deterioration in riverine systems. Meenachil river in the humid tropical region of Kerala, India, is one of a kind river with human settlement along the banks for all its 78 kms of flow through the Kottayam District. The analysis of streamflow from four stream gauge stations was done using Range Variability Approach. The analysis was down as a two-time period analysis with the parametric approach with the period separation taken according to prior studies on land-use change. The analysis shows a high degree of alteration, which can be attributed to the land-use change and can be understood as the root cause for the deterioration of water quality and also the ecological distress, which is well documented in the downstream and watershed regions of the river.
Micro plastics are primarily classified as individual pieces of synthetic material made of wide range of organic polymers which is generally called as ‘plastic’. Micro plastics are generally preproduction pellets, micro beads, polymer fibers and degraded micro plastic. Micro plastics make up to as much as 85 percentage of the plastic pollution in the shorelines. This large percentage in the total number of pollutant causes ecological stress caused by the biomagnifications along the food chain. Estimations show that globally majority of micro plastics comes from the runoff of 10 rivers along which includes the Ganges and Indus. To understand the role rivers, play as micro plastic carriers from land to oceans, the sampling of micro plastic is done at the relatively less populated part of Noyyal river and test are carried out to identify presence of micro plastic in the sample. Visual Identification method was used to identify the micro plastic components with relative ease and economy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
