@@lyyai 首先我查到了官方版本的,说是含不含看各地生产厂商,具体要看是哪家厂出品,也没具体列出来哪个地区含哪个地区不含。然后我做油工的朋友强烈建议我换掉(我才搭好2天)。。。还把原先的raised bed给送人了。她的说法是,你非得要用么?重金属会迁移好吗!所以我打算拆,home depot一家供货商的自述内容是,Thanks for your question. The majority of the manufacturing facilities do not use fly ash, but the use of it can vary by region. One thing to note is that fly ash is used to stabilize soils in commercial farming and is recognized by the U.S. Green Building Council’s LEED rating system as a post-industrial recycled material. If fly ash is used in the planter wall block, it chemically reacts with the cement during the hydration process and becomes an integral part of the structure. Therefore the fly ash itself is bound inside the product and would not be subject to leaching. If any were to be absorbed, it would be reduced by the water that carried it.
绝大多数Home depot销售的商品都有safety data sheet,法律要求凡生产与职业病安全相关产品的厂商必须提供的。上面会列明所有的风险因素,材料等等。但不是包装的一部分,网站也没有,可以Home Depot店里或者邮件索取

This^^^! @Tina's garden and life Or read the q&a on the product and the manufacturers will answer whether their product has fly ash or not. Lowe's cinder blocks has questions and answers from Boral company that redirects the customers to use other products for gardening needs, etc. Look into your own products look to the current manufacturer providers of large hardware stores to find the answers for your area and purchases !!
? How can you know if there is heavy metal leaching and toxicity in the soil just by looking at the pH level??? 😶 That is like saying the use of tap water without purification/filter treatment and with heavy metal toxicity can be tested via a pH strip....

Yi-An Lee It is impossible to identify heavy Metal leaching and toxicity by testing PH level. I believe it is common sense. I mentioned I would send the soil to a specific lab in the future, meanwhile I will monitor the PH level because Of the research reports by Oregan State University regarding lime leaching from the blocks at 4:22. I think this is also a sign telling if there is serious leaching. Sorry if I misled you.
