实验以云南省蒙自市农贸市场、文萃农贸市场和九龙农贸市场的鲫鱼为对象,分别取鲫鱼的眼睛、鳔、肌肉、肠和鳃组织进行微波消解,利用原子吸收分光光度计测定其重金属含量。结果表明:3个农贸市场鲫鱼体内各组织中铜的含量和肠、眼、肌肉、鳔中锌的含量没有超出国家标准,锌在鳃组织中的含量超标。 The experiments were conducted on the carp in the markets of Mengzi, Wenqian farmers market and Jiulong farmers’ market in Yunnan Province. The digestive organs of the carp were removed by microwave digestion and the contents of heavy metals were determined by atomic absorption spectrophotometer content. The results showed that the content of copper and the content of zinc in intestine, eye, muscle and gall in the three farmer’s markets did not exceed the national standard, and the content of zinc in gill tissues exceeded the standard.
