Poured down the drain, Gives off carbon oxides, water vapors, sulfur oxides, Slow addition to a large volume of water, best with small amounts of a carboxylic acid, such as acetic or citric acid, Toxic and very corrosive to most organisms; Raises pH in water bodies, Diluted organic solutions will reduce it to its constituent oxides, Not recommended due to its sodium content, Dangerous to organisms due to its strong oxidizing properties, Decomposes to sodium oxalate, then carbonate, releasing carbon monoxide and water vapors, High levels of sodium are toxic to plants, Breaks down at high temperatures releasing aluminium fluoride, HF fumes, Relative safe to environment, harmful for insects and small animals; occurs naturally, Breaks down to sodium polyphosphates and sodium oxide, giving off phosphorus oxide fumes at high temperatures, Corrosive to organisms, harmful to wildlife, Dangerous to wildlife in short term; toxic to plants due to sodium ions, Disproportionates to sodium chlorate and sodium chloride, giving off chlorine, Very toxic to organisms, especially aquatic ones; High levels of sodium are toxic for plants, Toxic to most fauna; High levels of sodium are toxic for plants, Dissolution in a large volume of water slowly, best with small amounts of a carboxylic acid, such as acetic acid, Addition in large amounts of water, followed by addition of aq.
