中文摘要:
      全氟辛基磺酸(PFOS)已被列入POPs名单,各国及国际组织相继出台法规和禁令对其生产和使用进行限制,并加紧了替代品的开发和评价。选取全氟丁基磺酸钾(PFBSK)作为潜在的替代品,采用OECD标准试验方法进行实际测试,并结合US EPA EPI Suite 4.0软件的计算预测,研究了PFBSK的基本理化性质(熔沸点、蒸汽压、水溶解性)和环境归趋性(水解性、光解性、生物降解性和蓄积性),并与PFOS及其盐的相关数据进行系统的比较。结果表明,PFBSK和全氟辛基磺酸钾(PFOSK)具有一定的相似性,都具有高熔沸点、低蒸汽压和明显的持久性。但二者在水溶性和蓄积性方面具有明显差异。20 ℃,PFBSK的水溶解度为49.3 g·L-1,极易溶于水;而PFOSK的水溶解度仅为519 mg·L-1
PFBSK的蓄积因子(BCF)为3.16,不具蓄积性;而PFOSK的BCF为6 531,并且在食物链中存在明显的生物放大效应。

英文摘要:
      After perfluorooctane sulfonate (PFOS) was listed in POPs, several countries and international organizations published regulation to manage and restrict the production and application of PFOS, and they made efforts to develop the alternatives. Selecting potassium perfluorobutane sulfonate (PFBSK) as the potential alternative, its physic-chemical properties (melting point, boiling point, vapor pressure and water solubility) and environmental fate (hydrolysis, photolysis, biodegradation and bioconcentration) are investigated by tests according to OECD guidelines and calculation by US EPA EPI Suite 4.0, and compared systemically with those of PFOS and its salts. The results showed that PFBSK and potassium perfluorooctane sulfonate (PFOSK) had some similarities such as high melting and boiling point, low vapor pressure and high persistence, while the solubility and bioconcentration between PFBSK and PFOSK were much different. The solubility of PFBSK is 49.3 g·L-1 (20 ℃), which showed it is highly water soluble. However, the solubility of PFOSK is only 519 mg·L-1. PFBSK showed low accumulation with BCF of 3.16. BCF of PFOSK is 6 531, and it also showed biomagnification in food chain.
