Abstract

Hair mercury concentrations were measured in 41 cats and 34 dogs living in Kanagawa, Saitama and Tokyo Prefectures. Total mercury concentrations measured by atomic absorption spectrometry were significantly higher (P < 0.01) in cats [7.40 parts per million (ppm) in males and 7.45 ppm in females] than in dogs (0.99 ppm in males and 0.66 ppm in females). Mercury in cat hair was correlated with age (P < 0.01) and higher in cats fed with foods prepared by the owners than in those fed with commercial pet foods. Mercury concentrations in the animals' foods were markedly higher in fresh tuna (0.153 ppm) than in commercial pet foods (0.008-0.014 ppm).

摘要

对生活在神奈川县、埼玉县和东京都的41只猫和34只狗的毛发汞浓度进行了测量。通过原子吸收光谱法测得的总汞浓度，猫（雄性为百万分之7.40，雌性为百万分之7.45）显著高于狗（雄性为百万分之0.99，雌性为百万分之0.66）（P < 0.01）。猫毛中的汞与年龄相关（P < 0.01），并且由主人自制食物喂养的猫比食用商业宠物食品的猫汞含量更高。动物食物中的汞浓度，新鲜金枪鱼（百万分之0.153）明显高于商业宠物食品（百万分之0.008 - 0.014）。
