In 2010, samples of muscles, liver and gills of Tilapia (Oreochromis sp.) were collected from eighteen reservoirs of four districts in Sri Lanka: Anuradapuraya, Polonnaruwa (North Central Province), Hambantota (Southern Province) and Ampara (Eastern Province). Cd, Pb and Hg were determined using atomic absorption spectrometry. Mean Cd, Pb and Hg concentrations in muscle were 0.03 mg/kg, 0.06 mg/kg and 0.26 mg/kg, respectively, while gills contained 0.02 mg/kg, 0.44 mg/kg and 0.36 mg/kg, respectively, on a dry weight basis. The amounts of the three metals in liver were 0.30 mg/kg, 2.07 mg/kg and 0.52 mg/kg on a dry weight basis. The results revealed that the level of heavy metal concentration in Tilapia does not exceed the maximum limit for human consumption according to the European Union and Sri Lankan guidelines.
2010 年，从斯里兰卡四个地区的 18 个水库中采集了罗非鱼（奥利亚罗非鱼）的肌肉、肝脏和鳃样本：阿努拉德普勒亚、波隆纳鲁瓦（中北部省）、汉班托塔（南部省）和安帕拉（东部省）。采用原子吸收光谱法测定 Cd、Pb 和 Hg 的含量。肌肉中 Cd、Pb 和 Hg 的平均浓度分别为 0.03mg/kg、0.06mg/kg 和 0.26mg/kg，而鳃中 Cd、Pb 和 Hg 的浓度分别为 0.02mg/kg、0.44mg/kg 和 0.36mg/kg，均为干重基础。肝脏中这三种金属的含量分别为 0.30mg/kg、2.07mg/kg 和 0.52mg/kg，均为干重基础。结果表明，根据欧盟和斯里兰卡的指导方针，罗非鱼体内重金属浓度水平未超过人类食用的最高限量。
