1. \"Classification Standards for Toxicity Hazards and Explosion Risks of Chemical Media in Pressure Vessels\" HG/T20660-2017 – there are significant changes compared to the 2010 version; for example, sulfuric acid was previously classified as having moderate toxicity hazards, but now it is classified as having extreme toxicity (it is carcinogenic)； The ammonia level was mild before, but is now moderate. Wait, 2. The hierarchical calculation is in line with \"Classification of the Hazard Level of Occupational Exposure to Toxic Substances\" GBZ 230-2010. However, if many parameters of certain substances are unknown, it is not possible to classify them. 3. What are the respective toxicity levels of manganese sulfate, cobalt sulfate, and nickel sulfate?
