The section on "Environmental effects", as well as being poorly written, seems disingenuous. It spends a lot of words on the (uncited) claim that STPP isn't poisonous, but that's not really the issue of concern with this substance. The issue is that it's an inorganic phosphate, and (like other inorganic phosphates) it's a nutrient (not a poison) to organisms like plankton. Think "phosphate fertilizer." Phosphates contribute to blooms that deplete other nutrients and mess up the food chain, as in the Gulf of Mexico dead zone. Anyone care to write some more-balanced text on the environmental issues surrounding STPP? 69.63.59.137 02:44, 31 October 2007 (UTC)
The article states that "As STPP is an inorganic substance, biodegradation studies are not applicable." This is incorrect, as biological organisms are capable of 'degrading' (i.e. using) many inorganic substances. As mentioned by 69.63.59.137 above, STPP may even be a food source. --66.92.171.249 (talk) 03:29, 25 April 2008 (UTC)
