本研究旨在探讨鲤鱼肌肉中部分重金属与微生物指标(细菌总数-TBC、中温厌氧芽胞杆菌-MASB)的含量及其相关性。2003年10月(HornéObdokovce池塘--池塘A)和12月(Budmerice池塘--池塘B)用围网在池塘捕鱼的框架内捕捞鱼类。所选金属的浓度用Pye unicam SP9原子吸收光谱仪测量。重金属含量(mg/kg湿重)为：Fe 3.47~15.15；Mn0.14~0.42；Zn 3.47~9.52；Cu0.24~1.32；Co0.05~0.17；Ni0.07~0.42；Cr0.08~0.19；Pb0.11~0.30；Cd 0.01~0.05。MASB和TCB计数(CFU/g)分别为1.12~7.76×10~(3)和0.03~7.59×10~(6)。池塘间对铜、镍、铬的生物积累量以及MASB数均有显著差异(P<；0.05)。36例中只有12例出现了相反的生物蓄积趋势。TBC-Mn和TBC-Cd关系中，除镍外，MASB数与累积重金属呈正相关，TBC与累积重金属(除铬外)呈负相关(P<；0.05)。铅浓度超过斯洛伐克食品法典委员会允许的最大值(0.2毫克/公斤)，POOL-A和POND-B分别超标60%和40%。两个池塘的MASB计数都100%超过了最高允许浓度。平均而言，鱼肉中金属含量的大小顺序为：(POND-A)Fe>；Zn>；Cu>；Mn>；铅>；铬>；Ni>；Co>；Cd；(POND-B)Fe>；锌>；铜>；锰>；铅>；镍>；铬>；Co>；Cd。
The purpose of this study was to assess concentration and correlation of selected heavy metals and level of some microbiological indicators (total bacteria count-TBC, mesophilic anaerobic sporulating bacteria-MASB) in the muscle of common carp (Cyprinus carpio). Fish were collected by seine net within the frame of pondfishing, in October (pond Horné Obdokovce--pond A) and December (pond Budmerice--pond B) 2003. Concentrations of selected metals were measured using an atomic absorption spectrophotometer Pye Unicam SP9. The concentrations of metals (mg/kg wet weight basis) ranged as follows: Fe 3.47-15.15; Mn 0.14-0.42; Zn 3.47-9.52; Cu 0.24-1.32; Co 0.05-0.17; Ni 0.07-0.42; Cr 0.08-0.19; Pb 0.11-0.30; and Cd 0.01-0.05. The count of MASB and TCB (in CFU/g) varied as follow: 1.12-7.76 x 10(3) and 0.03-7.59 x 10(6), respectively. Significant differences (P < 0.05) for Cu, Ni, and Cr bioaccumulation, as well as for count of MASB between ponds were recorded. An opposite trend of bioaccumulation was found in only 12 of 36 cases. Positive correlations between counts of MASB and accumulated heavy metals, except Ni and negative correlations between TBC and accumulated heavy metals, except Cr, were recorded, (P < 0.05) for TBC-Mn and TBC-Cd relationship. Lead concentrations exceeded the maximum values allowed concentration in Slovakia by Codex Alimentarius (0.2 mg/kg) by 60% for pond-A and 40% for pond-B. The level of MASB count exceeded the maximum allowed concentration in 100% by both ponds. On average, the order of metal concentrations in the fish muscle was: (Pond-A) Fe > Zn > Cu > Mn > Pb > Cr > Ni > Co > Cd; (Pond-B) Fe > Zn > Cu > Mn > Pb > Ni > Cr > Co > Cd.
