The inventory of sources, environmental releases and risk assessment for perfluorooctane sulfonate in China
Abstract
With about 100 t/y of the production volume, perfluorootane sulfonates (PFOS) are mainly used for metal plating, aqueous fire-fighting foams (AFFFs) and sulfluramidin China, and the use amount is about 30-40 t/y, 25-35 t/y and 4-8 t/y respectively. Based on the inventory of PFOS production and uses with geographic distribution educed from statistics, environmental risk assessment of PFOS was taken by using EUSES model, as well as its environmental releases were estimated both in local and regional levels in China. While the environmental release from manufacture is significant in Central China region, metal plating was identified as the major PFOS release source in regional level. The East China region shows the most strong emission strength of PFOS. Though the predicted environmental concentrations (PECs) were not exceed current relevant predicted no effect concentrations (PNECs) of the risk characterization for PFOS, higher PECs was estimated around major PFOS release sources showing undesirable environmental risk at local level.

Limited data indicate that human concentrations of PFOS are increasing in China where the production of these substances has increased.
“In contrast, limited data indicate that human concentrations of PFOS and PFOA are increasing in China where the production of these substances has increased.”

China now manufactures PFOS.
“However, China now manufactures PFOS, and according to Zhang et al. [60] the production volume of PFOS increased from 30 tonnes in 2002 to 247 tonnes in 2006.”
Since 2006, production volumes of PFOS in China declined to about 100 tonnes/year in 2008 as a consequence of international legislation to restrict or eliminate PFOS production.
“Since then, production volumes of PFOS in China declined to about 100 tonnes/year in 2008 as a consequence of international legislation to restrict or eliminate PFOS production.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
