Abstract

A realistic release estimation is key when assessing whether the use of a chemical can be considered as environmentally safe. For practically all industrial, professional and consumer use patterns, air emission measurements are absent or available for only 1 or, at best, a handful of volatile chemicals. When using such empirical data in the release estimation of other chemicals, environmental risks will be underpredicted for more volatile chemicals or unnecessarily overpredicted for less volatile chemicals. This short communication describes a pragmatic method to extrapolate release rates between chemicals with different physico-chemical properties used in similar conditions. The method is based on boundary layer theory and confirmed with empirical data. It is applicable to evaporative release from liquids and (semi-)solids. To demonstrate its value and ease-of-use in improving environmental risk assessments, the method was used to generate vapor pressure specific air release factors for hydrocarbons used as industrial laboratory reagents.

利用边界层理论提高环境暴露估算中空气释放因子的准确性。

在评估一种化学品的使用是否可以被认为是环境安全的时候，一个现实的释放估计是关键。对于几乎所有的工业、专业和消费者使用模式，没有或只有一种或最多几种挥发性化学品的空气排放测量。在使用这种经验数据对其他化学品的释放进行估计时，对挥发性较强的化学品的环境风险估计不足，对挥发性较弱的化学品的环境风险估计过高。这篇简短的通讯描述了一种实用的方法来推断在相似条件下使用的具有不同物理化学性质的化学品之间的释放速率。该方法基于边界层理论，并得到了经验数据的验证。适用于液体和（半）固体的蒸发释放。为了证明其在改善环境风险评估方面的价值和易用性，该方法被用于生成用作工业实验室试剂的碳氢化合物的蒸气压比空气释放因子。

期刊介绍： The Society of Environmental Toxicology and Chemistry (SETAC) publishes two journals: Environmental Toxicology and Chemistry (ET&C) and Integrated Environmental Assessment and Management (IEAM). Environmental Toxicology and Chemistry is dedicated to furthering scientific knowledge and disseminating information on environmental toxicology and chemistry, including the application of these sciences to risk assessment.[...] Environmental Toxicology and Chemistry is interdisciplinary in scope and integrates the fields of environmental toxicology; environmental, analytical, and molecular chemistry; ecology; physiology; biochemistry; microbiology; genetics; genomics; environmental engineering; chemical, environmental, and biological modeling; epidemiology; and earth sciences. ET&C seeks to publish papers describing original experimental or theoretical work that significantly advances understanding in the area of environmental toxicology, environmental chemistry and hazard/risk assessment. Emphasis is given to papers that enhance capabilities for the prediction, measurement, and assessment of the fate and effects of chemicals in the environment, rather than simply providing additional data. The scientific impact of papers is judged in terms of the breadth and depth of the findings and the expected influence on existing or future scientific practice. Methodological papers must make clear not only how the work differs from existing practice, but the significance of these differences to the field. Site-based research or monitoring must have regional or global implications beyond the particular site, such as evaluating processes, mechanisms, or theory under a natural environmental setting.
