In addition, we also found that erythrocyte fluidity decreased, osmotic fragility increased, membrane phospholipid percentage and protein composition changes abnormally, and Na+/K+-ATPase, Mg2+-ATPase and Ca2+-ATPase activities decreased (p less then 0.05). From the results, it can be concluded that CuSO4 exposure causes hemolysis of goat erythrocytes through oxidative stress to the structure and function of erythrocytes, showing a dose-time effect.In this work, carboxyl-functionalized hollow polymer microspheres (CHPMs) was successfully fabricated using poly (styrene-itaconic anhydride) particles as the core template and itaconic anhydride and trans-anethole cross-linked with divinylbenzene as the shell. The desirable microspheres and hollow structure of CHPMs were demonstrated by scanning and transmission electron microscopies, respectively. The characterized CHPMs as an adsorbent was packed into a solid phase extraction column to simultaneously detect the V(V), Cr(III), Cu(II), Cd(II), and Pb(II) in digested food samples by inductively coupled plasma-mass spectrometry (ICP-MS). A series of experimental parameters of solid-phase extraction (SPE) were investigated through vast experiments to improve sensitivity of the proposed method in metal ions detection. The detection limits of the method reached 0.8-3.2 ng L-1 for the target elements, and the relative standard deviations (RSDs) ranging from 1.2% to 3.5% were obtained from eleven parallel experiments using a 1.0 μg L-1 sample solution. The stability allowed the material to withstand more than 15 cycling while the recoveries remained above 88%. In food samples, the detection limits were at 0.20-0.80 μg kg-1, and satisfactory recoveries of 85-104% were obtained in spike tests of laver, fish as well as chicken.In this study, human health risk derived from radioactive pollution in drinking water of China was assessed based on gross alpha and beta.
