项目摘要

With a view of assessing health risk of chemicals of household-sprays used in a room, the concentrations and the changes with time of these chemicals after spraying were measured at several points in a temperature and humidity controlled room (25.4 m^3, 30゚C, 0.16 times/hour). Household-sprays generally consist of "vaporizing materials", "solvents", and "effective chemicals".(1)The concentrations of vaporizing materials, such as LPG, dimethyl ether, and iso-pentane, spread homogeneously in the room in about 30 minutes and kept almost constant. On the other hand, that of effective chemicals, such as tetramethrin resmethrin, permethrin, also spread homogeneously in about 30 minutes but kept decreasing and got to under detection limit in less than 10 hours. The changes with time of the concentrations of solvents, such as ethanol, toluene, were intermediate between vaporizing materials and effective chemicals. The vapor pressures of vaporizers, solvents, and effective chemicals were approximately 500 - 4,000, 30 - 50, and less than 1.0 *10^<-5> mmHg, respectively. The difference among these chemicals vapor pressure was considered to be a main factor effecting the changes with time of these chemicals in the air.(2)In assessing health risk of chemicals used in a room, in case of high vapor pressure chemicals the concentration in the air should be mainly evaluated and in case of low vapor pressure chemicals both the concentration in the air and the concentration on the surface of a floor should be evaluated.
为评价室内家用喷雾化学品的健康风险,在温湿度控制室(25.4m~3,30゚C,0.16次/h)测定了室内家用喷雾化学品的浓度及其随时间的变化。家用喷雾一般由“蒸发物质”、“溶剂”和“有效化学品”组成。(1)蒸发物质的浓度,如液化石油气、二甲醚和异戊烷,在大约30分钟内在房间内均匀扩散,并几乎保持不变。而有效化学物质如氯氰菊酯、氯氰菊酯、氯氰菊酯在30分钟左右扩散均匀,但持续下降,在10小时内降至检出限以下。乙醇、甲苯等溶剂的浓度随时间的变化介于挥发物和有效化学品之间。蒸发器、溶剂和有效化学品的蒸气压分别约为500-4000、30-50和小于1.0×10;-5 mm Hg。这些化学品的蒸汽压差异被认为是影响这些化学品在空气中随时间变化的主要因素。(2)在评估室内使用的化学品的健康风险时,对于高蒸气压化学品,应主要评估空气中的浓度;对于低蒸气压化学品,应同时评估空气中的浓度和地板表面的浓度。
