One-litre bottled water could contain about 2.4 lakh plastic pieces, new study finds

NEW DELHI, Jan 11 : A litre of bottled water could contain about 2.4 lakh plastic pieces on average, which is about 10 to 100 times greater than previous estimates that mainly concerned plastics of larger sizes, according to a new study.
While microplastics range from a micrometre — a millionth of a metre — to 5 millimetres, nanoplastics are smaller than a micrometre and are measured in billionths of a metre.

Researchers from Columbia University analysed three popular brands of bottled water sold in the US, measuring plastic particles down to 100 nanometres in size.
