Result The dust-retention amounts per unit area and the dust-retention amounts per plant of different tree species had bigger difference. Among trees, the dust-retention abilities of Ligustrum lucidum, Platycladus orientalis, Cedrus deodare, Platanus hispauiea anti Spohora japonica were stronger. Among shrubs, the dust-retention abilities of Viburnum odoratissimum, Pittosporum tobira, Euonymus japonicus and Lagerstroemia indica were stronger.

结果］不同树种的单位面积滞尘量、单株树木滞尘量均存在较大差异，乔木中，以女贞、侧柏、雪松、悬铃木和国槐的滞尘能力较强；灌木中，以珊瑚树、海桐、大叶黄杨和紫薇等的滞尘能力较强。

The results show that in the processes of shake 2out and finishing , molding , sand preparation , pouring , melting and coremaking , all the dusts are silica2 containing dust . The respirable dust （ 5 μm） occupies as high as 6915 %~ 78 %. Silica2containing dust in foundry air is not packed by Al. It indicates that silica dust in foundry air is fresh and highly pathogenic.

结果表明，清理、造型、配砂、制芯、熔化和落砂等工序游离SiO2 含量均超过10 %，分散度小于5μm的可吸入性粉尘偏高（6915 %~78 %），空气中矽尘没有Al 的包裹，是新鲜的粉尘，致病性强。
