得克萨斯州一家化工公司继续生产塑料容器之际，机构修改网站措辞美国环境保护署悄然撤回了美国已淘汰两种最危险的Pfas化合物——Pfoa和Pfos的说法。
Agency changes wording on website as Texas-based chemical firm continues manufacture of plastic containers The Environmental Protection Agency has quietly backtracked on a claim that the US has phased out two of the most dangerous Pfas compounds – Pfoa and Pfos.
环保署发现，饮用水中接触这两种化合物几乎任何水平都不安全，国际癌症研究机构将Pfoa列为“对人类致癌”，将Pfos列为“可能对人类致癌”。尽管如此，环保署仍允许休斯顿的Inhance公司生产容器，Pfoa已被发现从这些容器中高浓度渗入容器内物品。该公司每年生产多达2亿个塑料容器，广泛用于美国经济各个领域。
The EPA has found that virtually no level of exposure to either in drinking water is safe, and the International Agency for Research on Cancer classifies Pfoa as “carcinogenic to humans” and Pfos as “possibly carcinogenic”. Still, the EPA is allowing Houston-based Inhance to produce containers from which Pfoa has been found to leach at high levels into the containers’ contents. The company makes up to 200m plastic containers annually used across the US economy.
