DUBLIN — Global plastic pollution is heading for an “irreversible tipping point,” according to a study published on Friday in the journal Science. Despite worldwide alarm triggered by shocking images of rivers and seas deluged with plastic rubbish, the problem may be already beyond repair, the researchers warned, saying that “rates of plastic emissions globally may trigger effects that we will not be able to reverse.” Lead author Matthew MacLeod of Stockholm University said plastic “leaks out into the environment everywhere,” including in countries “with good waste-handling infrastructure.” Even then, recycling has “many limitations,” according to co-author Mine Tekman of the Alfred Wegener Institute in Germany, as wealthy nations ship rubbish “to countries with worse facilities.”

Study suggests Atlantic plastic pollution far worse than thought – dpa international

LIMERICK — Plastic pollution in the Atlantic Ocean could be 10 times worse than previously thought, according to estimates by the UK-based National Oceanography Centre (NOC) published on Tuesday in the journal Nature Communications. Samples of Atlantic seawater taken at depths of up to 200 metres suggest the “supply of plastic to the ocean [to] have been substantially underestimated,” the NOC reported. The NOC said the volume of invisible or near-invisible microplastics “is comparable in magnitude to estimates of all plastic waste that has entered the Atlantic Ocean over the past 65 years.” The NOC’s Katsiaryna Pabortsava, the report’s lead author, said that earlier studies did not measure “the concentrations of ‘invisible’ microplastic particles beneath the ocean surface.”
