The British "Nature Communications" published a new report on the 18th.
The National Oceanographic Center of the United Kingdom reported that there are about 12 million to 21 million tons of microplastic waste in the upper 200 meters of the Atlantic Ocean
.
Our lack of reliable quantitative data from microplastic accumulation systems, especially in remote areas such as oceans, hinders the assessment of ecological and environmental damage caused by microplastic accumulation
.
This time, the UK National Oceanographic Centre research team carried out detailed sampling and quantification of plastic pollution from 12 locations across a 10,000-kilometer north-south transect of the Atlantic Ocean
.
At each sampling station, samples were taken from three depths below the sea surface: 10 m, 10 to 30 m below the oceanic mixed layer, and 100 m below the intermediate sample
.
Based on trends in plastic waste generation from 1950 to 2015, and assuming that the Atlantic Ocean continues to receive a portion of the global plastic waste over 65 years, the research team estimates the plastic input in Atlantic waters and sediments to be between 17 and 47 million tonnes
.
In addition, the extent and depth of the impact of plastic waste is far beyond imagination across the entire ocean
.
According to the report, oysters, prawns, squid, crabs and sardines in a seafood market in Australia, after assessing the level of plastic residues through technical means, found that the plastic residue content per gram of tissue was 0.
04 mg in squid and 0.
07 mg in prawns.
Oysters are 0.
1 mg, crabs are 0.
3 mg, and sardines are 2.
9 mg
