Recycling plastics have become the global done approach, but will still have plenty of plastic garbage can't recycle. Through the wind, the flowing water of carrying and the effect of gravity, most of the plastic garbage finally went into the ocean, the sea of all kinds of empty bottle is "the tip of the iceberg," and the ocean most of the plastic pulverized are hard of people found naked eye.
Relative to a DaTiLiang plastic garbage for, in the form of plastic particles to sea life pulverized become more virulent. According to environmental news network reports, deutscher forschungszentren e.v. polar ocean institute subordinate and German scientists Alfred? Wegener's (Alfred Wegener) led a research team, and strive to on the Marine pollution plastic depth survey.
The researchers first determined the plastic particles caused the pollution problem of the build. These is no more than 5 mm in diameter of tiny plastic particles sometimes sea surface floating into,color film or sinks down the bottom of the sea, and the coast or washed. Due to the small size, these plastic garbage can be Marine creatures in intake, and adds up in animal tissues of the endings. Some plastic particles contains toxic components, into the organisms would cause serious disease. And through the food chain, and the plastic particles and may all the way into the human body.
Study group design a standardized way of plastic particle pollution to the extent of the measuring record. The scientists analyzed the previous studies of this problem 68 kind of scientific research,pvc color film found that the use of the method is different, it is difficult to measure precise different observation area plastic particle pollution difference. For example, many of the previous studies using make up nets to filter the water in the plastic particles, and make up the size of the network eye can affect the results of the measurement. So for accurate measurement and relatively speaking, a standardized determination method is very important.
The team hopes to, in the future work in all other researchers, pvc shower curtaincan accept their standardization method, in order to enhance the reliability of the research work, improve the plastic particle pollution in the ocean research of certainty, eventually determine such pollution on the ecological system and a threat to human health. At present the team's achievements have been published in the latest issue of "environmental science and technology".
