The imprinted polymers prepared were then characterized and evaluated through scanning electron microscopy (SEM) and an equilibrium adsorption experiment. The results showed that the MIPs had specific adsorption capacities for five pyrethroid pesticides. A solidphase extraction column was prepared using the synthesized polymers as the adsorption material, and a molecularly imprinted solid-phase extraction-gas chromatography equipped with an electron capture detector (MI-SPE-GC-ECD) method was confirmed for the determination of five pyrethroid pesticide residues in agricultural products. A good linear relationship was present between the peak area and the concentration of pyrethroid insecticides within the range of 2-100 μg/kg. The correlation coefficient (R&lt;sup&gt;2&lt;/sup&gt;) was greater than 0.9930, and the minimum limits of detection and quantification were 15.5-25.8 and 54.3-88.1 ng/L, respectively. Under different levels of additives, the standard recovery of pyrethroid pesticides in the samples varied from 72.8% to 110.2%, and the relative standard deviation (RSD) was less than 5.5%.

We here used Mann-Kendall and sliding t-tests to analyze the annual runoff and annual sand transport in the basin based on data from Ganjiang River hydrological stations from 1958 to 2019. Our results show that: (1) the interannual variation of runoff in the Ganjiang River basin from 1958 to 2019 is significant, alternating between flat, dry, and abundant water conditions, with an abrupt change occurring in 1990 at all stations. (2) The annual sand transport at all stations showed a significant decrease, being most significant at Waizhou and Ji'an stations. Abrupt changes in the amount of sand transported at four upstream stations, Ji'an Station, and Waizhou Station were seen during 2002, 1994, and 1997, respectively. (3) Sand transport in the basin varies with runoff, and the two are highly correlated.
