Scientists at the University of California at Santa Barbara found that synthetic microfibre in soil is almost as much as in water. Since their production began in the 1950s in the form of polyester and nylon, at least 5.6 metric tons of synthetic microfibre have separated from clothes when washing.
Half of them were produced in the past decade, BTA reported.
Analyzing the amount of microfibre discharges in sewage around the world is almost impossible, moreover, in many areas there are no data on waste water treatment. In these cases, American scientists have used as its substitute the income of the population.
Their model shows that almost half of the microfibre released remains on land - in soil (1.9 metric tons) or in landfills (0.6 metric tons). Almost 2.9 metric tons of microfiber are poured into the water basins.
Scientists admit that their calculations have drawbacks - their model is based on many assumptions and simplifications, such as frequency of laundry around the world, percentage of clothes that are used annually, owning washing machines.
"The large-scale purification of the environment from microfibre does not seem technically possible or economically justified. Therefore, the focus should be on the prevention of emissions,” said the head of the study Jenna Gavigan.

Synthetic microfibres turned away from clothing reach not only water pools but also accumulate in the soil, reported Syons allert.tags:
