The present invention relates to a method for detecting microplastics in cephalopods. Specifically, the method includes the following steps: mixing organism tissues of samples from cephalopods with a digestion solution for digestion; suction-filtering and drying the digested organism tissues; and performing microscopic examination and infrared detection on the organism tissues to calculate the abundance of microplastics. A ratio of the dry weight (g) of the organism tissues to the volume (mL) of the digestion solution is 1: (10-30); and the concentration of the digestion solution is 5-20wt%. 200 pm Fig. 4 50 Compare: 79.91 Nopylene gfc ncm S50 Cornare:47.45 P 50~ Cornare:47.15 H '3 s(-hyd Xqh 56 Compare: 47.04 H Propylenecgybo in 50 Corn re:46.09 3500 3000 2500 2000 1500 1000 Wave number (cm-1) Fig. 5 200 pm Fig. 6
