一、涂料有害物质检测项目及标准分析
1、涂涂料有害物质检测项目
料的有害物质项目其实就是围绕着挥发性有毒有害物质及重金属类有害物质来进行的。涂料有害物质常规检测项目主要有挥发性有机化合物含量、苯、甲苯、乙苯、二甲苯、游离甲醛、游离二异氰酸酯、甲醇、卤代烃、铅、镉、铬、汞等重金属。

二、涂料有害物质检测之对人体危害分析
涂料中的有害物质主要来自生产过程中使用的各种原料,如各种树脂、颜料、填料、添加剂、溶剂等都会带来各种有毒物质。涂料有害物质的毒性与其形态,浓度和化合状态有关。涂料中的有害物质在涂料使用过程中与人体接触,或在生物体内富集后通过生物链进入人体,并在人体内积聚,就会造成不同程度的中毒。
例如,重金属铅对多个中枢和外周神经系统中的特定神经结构具有直接毒性作用,会导致智力下降,特别是让孩子患有学习障碍,感觉功能障碍,此外,铅还会抑制血红蛋白的合成,缩短血液循环中的红细胞生命周期,终导致贫血;重金属汞中毒的特点是烦躁,口吃,焦虑,注意力不集中,记忆力减退,精神抑郁等;六价铬虽然是一种吞入性毒药,但是皮肤接触也可能引起敏感,更容易引起遗传缺陷,吸入可能导致癌症,并且还会造成持久性环境危害。

WASHINGTON—Scrambling for how to respond to the incumbent potentially topping their ticket again, party operatives confided to reporters Monday that Democrats across the nation were extremely worried President Biden would be healthy enough to seek reelection in 2024. “Whether you’re talking to senior party leaders, state-level officials, grassroots organizers, or the voters themselves, you realize the one thing we all took comfort in was knowing the president would probably be dead by now,” said a longtime Democratic strategist who spoke on condition of anonymity, adding that while there were a few political analysts who predicted Biden would survive four years in office, even they assumed he would be far too incapacitated, both mentally and physically, to run for a second term. “At this point, we can’t rule out his 2024 candidacy, which is an absolutely terrifying prospect. The whole plan in 2020 was to take back the White House with Biden and then the next time around—after he had fallen and broken a hip or suffered a massive stroke or flatlined on live TV in the middle of a big speech—nominate someone Democrats actually like. But unfortunately, it’s looking more and more like the president will still be breathing and have the cognitive functioning needed to put his name on the ballot one more time. This is a complete disaster.” The source went on to state that several Cabinet-level officials were considering broaching the subject directly with the president to gauge his interest in passing away sooner rather than later.
