本文采用将瓜子黄杨的降汞效果．并研究空泥盆的吸汞影响因素，同时将瓜子黄杨置于汞处理间，观察其现场降汞效果。结果表明：瓜子黄杨放置于染毒柜内４８ｈ后．柜内空气中汞浓度下降了５１％左右，且可维持较长时间的降汞趋势，而空泥盆置于染毒柜内４８ｈ后．以１６ｈ时的最低浓度计算，便下降了１０％左右，到４８ｈ，柜内浓度又回升到最初的３３８μｇ／ｍ３，提示瓜子黄杨具有较强吸汞能力，并使柜内空气中汞浓度下降。现场降汞效果观察表明．在放置瓜子黄杨５周后．能降低空气中汞浓度６０％。
In this paper, melon seeds will reduce mercury effect. In addition, the influence factors of aspiration mercury in the empty muddy pot were studied. At the same time, the melon seeds were placed in the mercury treatment room to observe the mercury reduction effect in the field. The results showed that the melon seeds were placed in the cabinet for 48h. The concentration of mercury in the air inside the cabinet decreased by about 51%, and the trend of reducing mercury could be maintained for a long time, while the empty mud pots were placed in the cabinet for 48 hours. At the lowest concentration at 16h, it dropped by about 10%. After 48h, the concentration in the cabinet rose back to the initial 338μg / m3, which indicated that the poplar had a strong mercury absorption capacity and decreased the mercury concentration in the air inside the cabinet. On-site mercury reduction results show. After placing melon seeds boxwood 5 weeks later. Can reduce the concentration of mercury in the air by 60%.
