据青浦区政府新闻办介绍，7月6日上午，青浦区赵巷镇上海益而益电器有限公司(沪青平公路2933弄1号)反映有员工眼睛不适，部分公司人员出现呕吐等现象。经查，上海益而益电器有限公司附近的上海浩源生物制品有限公司在厂房屋顶防水装修过程中所用的涂料散发出较为刺激的气味，由于风向等因素，益而益公司部分员工由于吸入气体造成身体不适，先后共有69人赴中山医院青浦分院就诊，目前其中两人因胸闷等症状，需进一步留院观察，其余均已出院。
记者从上海市环保部门了解到，经过定性分析后，证实涂料内含有少量的丙烯腈，该物质作为化学品是有毒的。目前消防部门已通过降温、覆盖等措施减少异味，环保部门将对异味源头进行进一步追踪和监测。目前根据环保监测，刺激气味已经明显下降，随后将组织力量彻底拆除屋顶。
