Preliminary results from the volunteer survey conducted in September and October show that more than four-fifths of shoreline sites had plastic bottles, according to RTÉ News.
While the rate of 3.6 per 100m of shore indicates a downward trend, it is still far higher than those in Scandinavia.
And it comes with a rising rate of bottle tops, especially “complex caps” that come with sports drinks, as The Irish Times reports.
In other summary results ahead of the final report due in the sprint, plastic bags were found at 40% of sites, though their numbers have fallen from a peak of 18 per site before the bag tax to an average of two this year.
While nearly half of locations surveyed were rated as “reliably free” of pollution by sewage, there are concerns over “worrying” nitrate levels in freshwater streams entering the sea.
That’s particularly so on the South and East Coasts, and in Northern Ireland where 13% of sites had levels exceeding EU directives.
