Whether or not microplastics have harmful effects on plants and animals has not yet been conclusively established. The different properties of microplastics determine whether and how the microplastics are absorbed by living organisms and whether they are harmful to them.
"To assess the ecologic danger posed by microplastics, one must also consider indirect effects in the food web", say Sebastian Höss (Ecossa) and Marie-Theres Rauchschwalbe (Bielefeld University). The researchers from the joint project MikroPlaTaS looked at these effects using nematodes as an example.
Numerous one- to two-person households, an increase in mail-order business as well as the popular "to-go" culture are causing a steady rise in the consumption of plastic packaging in Germany. While approximately 1.8 million tons of plastic were produced per year in 2000, this figure had already risen to 3.1 million tons by 2016.
