The hottest scientific research found that plastic

Scientific research found that 9% of fish in the "Pacific Garbage belt" sea area have plastic in their stomachs
according to foreign media reports, The United States Scripps plastic accumulation expedition (SEAP) main technical parameters: the maximum actual strength ultimately constitutes the "new material support level improvement project". Force test: 50kN; measuring range: 0n (5) 0kn; experimental force accuracy; better than ± 1%; displacement resolution: 0.01mm; displacement measurement accuracy: better than ± 1%; stretching stroke: 650mm. China's synthetic rubber production capacity reaches 5.09 million tons (which can be increased); Tightening stroke: 650mm (can be increased); Experimental stroke: 650mm (can be increased); Displacement speed control range: 1mm/min ~ 300mm/min; Displacement speed control accuracy: better than ± 1%; From the current research, the level of experimental machine is better than level 1; Deformation indication error: ≤± (50+0.15l); Size of the experimental machine: 660*420*1780 mmlex) two researchers found that 9.2% of the 141 samples of 27 species of fish located in the middle ocean contained plastic debris in their stomachs, which were slightly smaller than human finger nails before degradation. The researchers said that because the plastic debris is small, it is not possible to identify the prototype of the plastic
on the basis of this data, researchers speculate that about 12000 to 24000 tons of plastic are swallowed by fish in the middle waters of the North Pacific every year
researchers also said that the study found that about 9% of fish have plastic in their stomachs, which may be lower than the actual value, because fish may digest plastic and even convert it into part of themselves, or die due to eating plastic. These situations were not considered, so the 9% data may be far lower than the actual value
the results of this study were published in the marine ecology progress series published on June 27
