Palladium(Ⅱ)and chloride ions can form four kinds of complexes,and the below is their formations in accordance with their stability constant Eq.(1-4)[1]:Pd2++Cl- → PdCl+,logβ1=4.47 (1)Pd2++2Cl- → PdCl2,logβ2=7.74 (2)Pd2++3Cl- → PdCl3-,logβ3=10.20 (3)Pd2++4Cl- → PdCl42-,logβ4=11.50 (4).

亚硝酸盐是作为一种允许使用的食品添加剂,在控制的安全范围内使用不会对人体造成危害.但摄入过量的亚硝酸盐,血红蛋白的亚铁将氧化为高铁状态,从而形成不能送氧的高铁血红蛋白;高铁血红蛋白达到30%~50%时,可导致贫血性缺血,造成全身各组织特别是脑组织的急性损害,出现呼吸困难,神经机能紊乱,甚至死亡[1].

众所周知,经常与空气中的颗粒物质接触能够引发一系列的疾病,包括心血管疾病,呼吸道疾病以及肺癌[1].颗粒物质能够导致这些疾病产生的主要原因在于它们的颗粒直径都小于等于10微米,能够通过喉咙、鼻子直接进入肺部扰乱机体的正常生理功能.一些文献已经报道了许多颗粒物质具有基因毒性,能够氧化损伤DNA、导致染色体突变等[2].
