Group 1 - The core point of the article is that Satellite Chemical Co., Ltd. has raised its ex-factory price for ethylene glycol to 3670 yuan/ton, an increase of 20 yuan/ton from the previous trading day, indicating a tight supply or improved demand in the spot market [1][4] - The increase in the ex-factory price is expected to positively impact spot prices, suggesting a bullish sentiment in the market [2][5] - The recent performance of the ethylene glycol futures contract (closing price of 3846 yuan/ton and settlement price of 3820 yuan/ton on December 26, 2025) indicates that the price adjustment may lead to a moderate upward trend in futures prices [2][5] Group 2 - The pricing mechanism for bulk commodities is based on big data and a pricing model, which generates a benchmark price used for transaction settlement [2][5] - The benchmark price can be utilized to determine settlement prices for specific dates or average prices over specified periods [2][5] - The pricing formula includes an adjustment coefficient (K) that accounts for factors such as account period costs, and a premium/discount (C) that includes logistics costs and regional price differences [3][5]

EPA同时重申了拜登政府2025年1月的结论：在当前使用条件下，甲醛对工人与消费者存在不合理健康 风险。《联邦公报》指出，该风险既包括急性皮肤接触、吸入引发的非致癌效应，也涵盖工人长期吸入 导致的致癌效应。EPA强调，控制急性感官刺激风险，可同时防范包括癌症在内的其他健康危害。值得 注意的是，化学品科学顾问委员会(SACC)对拜登政府时期EPA的评估方式提出批评，认为其过度依赖 《综合风险信息系统(IRIS)甲醛吸入毒理学审查草案》中的致癌与非致癌危害数值。 ACC强调，甲醛在住房、农业、交通、医疗及国家安全领域应用不可或缺。此前甲醛最终风险评估在 科学质量、同行评审及公众与跨部门意见征询方面未达法定要求，过度依赖IRIS项目评估。ACC认为， 将感官刺激列为最敏感指标、认可受控人体暴露研究比流行病学观察更具科学性，有助于推动甲醛风险 评估回归最优科研标准。 美国化学理事会(ACC)甲醛委员会对EPA该决定表示欢迎，并称EPA修订后的评估方法充分吸纳了 SACC、人类研究审查委员会等权威机构的建议，更符合《有毒物质控制法》对"最优可用科学"和"科学 证据权重"的要求。 中化新网讯 近日，美国环境保护署(EPA ...
