PFOS and PFOA concentrations in freshwater gammarids (caged) and wild fish from 15 continental sites (2018)
收藏资源简介:
This dataset reports concentrations of two perfluoroalkyl acids (perfluorooctanoic carboxylic acid - PFOA -; perfluorooctane sulfonic acid - PFOS -) in caged gammarids (Gammarus fossarum) and wild fish (chub Squalius cephalus; barbel Barbus barbus; roach Rutilus rutilus) from 15 sites in French rivers. Gammarids were collected at a pristine site, sorted in order to select male individuals of about 2 mm size, and exposed in the field for three weeks, without food added (AFNOR standard XP T 90-721 (2019) Encagement in situ de gammares pour la mesure de la bioaccumulation de substances chimiques). This was repeated three times (June, September and November) in 2018. Fish were caught by electrofishing between July and November, 2018. Each fish sample is composed of several individualsof the same size class. PFOS and PFOA were analyzed according to Aquaref (2014 - Composés perfluorés (chaine linéaire en C8) - Méthode d'analyse dans les biotes). The dataset comprises 90 gammarid records, 60 fish records, and quantification limits and control/blank samples.
本数据集记录了法国河流15个采样点中,笼养钩虾(Gammarus fossarum)以及野生鱼类(欧鳊Squalius cephalus、欧洲鲃Barbus barbus、斜齿鳊Rutilus rutilus)体内两种全氟烷基酸(perfluoroalkyl acids)的浓度,具体为全氟辛酸(perfluorooctanoic carboxylic acid, PFOA)与全氟辛烷磺酸(perfluorooctane sulfonic acid, PFOS)。 研究人员于一处未受污染的原生采样位点采集钩虾,分选选取体长约2mm的雄性个体,进行为期三周的野外原位暴露且不添加食物,实验参照法国标准化协会(AFNOR)标准XP T 90-721(2019)《钩虾原位富集化学物质生物累积性测试方法》(Encagement in situ de gammares pour la mesure de la bioaccumulation de substances chimiques)。该实验于2018年重复开展三次,分别为6月、9月及11月。 野生鱼类于2018年7月至11月间通过电捕鱼法采集,每份鱼类样本由同一体长组的多个个体组成。 全氟辛酸与全氟辛烷磺酸的分析参照Aquaref(2014)《全氟化合物(C8直链)生物样品分析方法》(Composés perfluorés (chaine linéaire en C8) - Méthode d'analyse dans les biotes)。 本数据集包含90条钩虾样本记录、60条鱼类样本记录,以及定量限与对照/空白样本相关数据。
