- One study examined the concentration of microplastic particles in 38 freshwater lakes in 23 countries.
- Experts warn that one of Australia’s lakes is the most polluted in the world, and others may be in a similar state.
- Concentrations of microplastics in some lakes are higher than in marine litter areas.
Researchers have detected microplastics in even the most remote lakes.
Some of the most severely affected lakes had higher concentrations than surrounding lakes in vast areas of litter that formed in the ocean.
Microplastic concentrations in Lake Brisbane ‘just there and cause for concern’
That’s significantly less than the worst-performing Lake Lugano (a glacial lake on the border of Switzerland and northern Italy, about 12 parts per cubic meter), but still “right there and a cause for concern”. .
The 10.9-hectare recreational lake was built as the centerpiece of the Forest Lake suburb, Brisbane’s first master-planned community.
“It’s a quintessential urban lake,” he says.
“I don’t think Forest Lake is any different than any other system with similar numbers of people.”
Research signals red flags for growing plastics crisis
Hamilton, who is part of a group of experts working to solve the problem of Forest Lake, said the study is a red flag as the world grapples with a growing plastic crisis.
Mr Hamilton said plastic pollution is a growing threat and people should pay attention because the presence of contaminants in humans and the plants and animals that humans eat is not fully understood.
