What are Micro-Plastics?
Micro-plastics have not been defined in particular. They are just tiny particles that result from the disintegration of bigger plastic materials. However, most researchers say that any plastic smaller than 5 millimetres in size is a micro-plastic. Hence, these are really, really teeny-tiny!
Plastics are made up of polymers, which are derived from fossil fuels. A whole lot of chemicals are added to the polymers—close to 10,000—to ensure that a given plastic has the desired properties...
The Yamuna River is the largest tributary of the Ganga. It travels barely a distance of 22 km through Delhi. However, this region contributes to about 80 per cent of its total pollution load. Currently, this stretch discharges waste water from almost 22 drains into the river. Untreated effluents, containing toxins and chemicals, released from houses and industries creates froth (white foam) on the river’s surface. Algae, in addition, prevents sunlight from venturing into the depths of this river. Plus, low water level in the river causes concentration of these pollutants…
Wetlands purify water through natural processes where aquatic plants act as bio-filters. Plants absorb phosphates and nitrates from the water and roots help to put back oxygen into the water.
Constructed wetlands are a cost-effective method of treating wastewater and polluted water bodies. These are low cost solutions and can be easily made or replicated.
