摘　　要：目的检测食蟹猴饲养基地猴舍中的氨气浓度及饮水中重金属含量。方法采集不同猴群、不同饲养方式、不同时点猴舍中的空气,纳氏试剂分光光度法检测氨气浓度。收集饲养基地内地下水出水口、蓄水池、猴舍终端、污水池等5个不同位置的水样标本,电感耦合等离子质谱仪(inductively coupled plasma mass spectrometry,ICP-MS)检测重金属含量。结果检疫群猴舍氨气浓度(0.59±0.03)mg/m3显著高于种群(0.34±0.03)mg/m3及商品群(0.27±0.04)mg/m3。不同饲养方式猴舍氨气含量依次为:检疫笼养(0.59±0.03)mg/m3>种群笼养(0.48±0.02)mg/m3>商品群圈养(0.30±0.02)mg/m3>商品群笼养(0.25±0.01)mg/m3>种群圈养(0.22±0.02)mg/m3。检疫群笼养、种群笼养明显较其他饲养方式猴舍氨气浓度高。不同猴群、不同饲养方式猴舍氨气在以早上清扫前含量最高。铁质水管连接的猴舍终端饮水中铁含量高于饮用水含量标准。结论本调研的食蟹猴饲养基地猴舍中的氨气浓度低于国家标准,铁质水管连接的猴舍终端铁含量超标。Objective The ammonia level in air and heavy metals in drinking water were explored in a cynomolgus monkey feedlot. Methods Air ammonia from different communities and feeding patterns of cynomolgus monkeys were collected at three time-points per day and determined by Nessler ＇s reagent spectrophotometry. Inductively coupled plasma mass spectrometry was applied to detect the level of heavy metals in drinking water from 5 different sampling sites in the feedlot,incluing the outlet of underground water,the water tank,both monkey cages equipped with PVC or iron pipes and sewage lagoon,respectively. Results Air ammonia levels in quarantine inspection flock cages（ 0. 59 ± 0. 03 mg/m^3） were significantly higher than in the cages of both reproductive flock（ 0. 34 ± 0. 03 mg/m^3） and sale flock（ 0. 27 ±0. 04 mg/m^3）.The ammonia level in air in different feeding patterns ranks as following： cage rearing of quarantine inspection flock（ 0. 59 ±0. 03 mg/m^3） cage rearing of reproductive flock（ 0. 48 ±0. 02 mg/m^3） captive bleeding of sale flock（ 0. 30 ±0. 02 mg/m^3） cage rearing of sale flock（ 0. 25 ±0. 01 mg/m^3） 〉captive bleeding of reproductive flock（ 0. 22 ±0. 02 mg/m^3）. The air ammonia concentrations of both former flocks were statistically higher than the latter three flocks. The highest air ammonia level among different flocks and feeding patterns occurred in the morning,before waste discharge clean-up. The iron concentration in drinking water in the cages equipped with iron pipes was higher than Chinese drinking water standard.Conclusions The air ammonia level was lower than the Chinese air quality standard. The iron concentration in drinking water in the cages equipped with iron pipes was higher than the Chinese drinking water standard.
