When it has a lot of impurities (or nutrients), it can vary from red, green, white, grey, brown, black to anything that is weird and filthy. Read about some important terms related to different colours of water that we come across in common parlance or which researchers use to understand better this elixir of life.
Bluewater: ‘Why is water blue in colour?’—humans must have raised this question since time immemorial. But in 1921, this query was resolved when Sir CV Raman raised and answered it successfully...
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...
