Combined toxicity of functionalized nano-carbon black and cadmium on Eisenia fetida coelomocytes: The role of adsorption.

Little is known about the potential threats of functionalized nano-carbon black (FNCB) combined with cadmium (Cd) to soil invertebrates. In this study, immunocompetent coelomocytes from Eisenia fetida are harnessed, and the joint cytotoxicity types of FNCB and Cd co-exposure are analyzed. The extracellular interaction mechanisms of FNCB and Cd were completely explored using adsorption kinetics and thermodynamics accompanied by isotherm batch experiments and Fourier infrared spectroscopy.
