Organic phosphate is
phosphate that is bound to plant or animal tissue,
living and dead, sewage,
body waste and food residues.
Polyphosphates are used for treating boiler waters and in detergents.TCP cleaner is tri-sodium phosphate. In water, polyphosphates are unstable and will eventually convert to orthophosphate. This will result in elivated levels of phosphates in the water system. High amounts of orthophosphate may indicate the presence of chemical fertilizers, polluted storm water run-off, poorly treated sewage or leaking septic systems. ( PO4 this is a phosphate group it can attach to Hydrogen to get phosphoric acid) (Ex: H3PO4) Eventually all this material will be available to plants as what we refer to as phosphates . The natural background levels of total phosphorus are generally less than 0.03 mg/L. The natural levels of phosphate usually range from 0.005 to 0.05 mg/L. Although levels of 0.08 to 0.10 ppm phosphate may trigger periodic blooms, long-term eutrophication will usually be prevented if total phosphorus levels are below 0.5 ppm and 0.05 ppm, respectively. (S) 1 ppm = 1mg/l = 1ug /ml = 1000ug/L .5 ppm = .5mg/l = .5ug /ml = 500ug/L 0.05 ppm = 0.05mg/l = 0.05ug /ml = 50ug/L Phosphates: Organic refers to living and inorganic non-living. Organic phosphates are in the bodies of living organisms, waste and carcuses. Minerals are released in the decomposition process and made available to plants and algae. In places such as Nowlands Lake the phosphates cycle between organic and inorganic which is now basically a large setteling pond  As plants and animals excrete wastes or die, the organic phosphorus they contain sinks to the bottom, where bacterial decomposition converts it back to inorganic phosphorus, both dissolved and attached to particles. This inorganic phosphorus gets back into the water column when the bottom is stirred up by animals, human activity, chemical interactions, or water currents. Then it is taken up by plants and the cycle begins again. (S) An excess of phosphates in and aquatic ecosystem can be devastating. Nitrogen can also be very problematic. * One pound of phosphorus can result in the growth 350-700 lbs. of green algae. * Algal blooms and excessive submerged aquatic vegetation growth can lead to the biological death, of a body of fresh water. * Blooms of blue-green algae can produce toxins that can cause a serious public health problem as well as damage aquatic habitats. * Excessive algal growth degrades fishing and boating activities, and impacts tourism and property values.

Evaluation of Sodium Bisulfate as a Replacement for Phosphoric Acid in a Conventional Mink Ranch Diet Phosphates in feed are likely the main source of phosphates in the our lakes, and they may not have to be used!
Is there some reason it is not used here? Cyanobacteria can access nitrogen
from the air {nitrogen fixation), therefore phosphate
is a main factor that limits their growth. It is
a "key" nutrient that can be measured to "predict"
their plankton blooms. Extensive and expensive water
sampling is probably not necessary.
Historically phosphate, whether in the form of fertilizer, feed or some detergents, has been an aquatic nightmare. Environmentally, to protect ecosystems, phosphorus has to be a "controlled substance". Phosphates added to mink feed make mink waste potentially more hazardous then that of other domestic livestock manure. Dr.Brylinsky pointed out this problem with mink feed. Many individuals, myself included, feel we are seeing more than just early warning signs of worst things to come. |

| Synopsis of five links
below: 1. Dr. Michael Brylinsky. (Research Associate Acadia Centre for Estuarine Research Acadia) stated that super phosphates could be in the feed of mink, thus contributing to the algae (bacteria) problem. 2. Nancy (http://www.novascotiaminkblog.com) says "Super phosphate is not put in feeds that I'm aware" 3. Dr. Hugh Hildebrandt (http://www.furresearch.org/) suggests Sodium Bisulfate as a Replacement for Phosphoric Acid. 4. & 5. (http://www.potashcorp.com/) shows the similarities between a fertilizer and a feed. There also appears to a semantic blur betwixt phosphate and super-phosphate. |

An Assessment of the Sources
and Magnitudes of Nutrient Inputs Responsible for
Degradation of Water Quality in Seven Lakes
Located Within the Carleton River Watershed Area of
Digby and Yarmouth Counties, Nova Scotia, Prepared for Nova Scotia Environment By M. Brylinsky Acadia Center for Estuarine Research Acadia University Wolfville Nova Scotia January 2012 http://www.gov.ns.ca/nse/surface.water/docs/NutrientSourcingReport.pdf Water quality surveys carried out by Nova Scotia Environment between 2008 and 2010 for a number of lakes located within the Carleton, Meteghan, and Sissaboo River watersheds have shown many of the lakes to be seriously degraded as a result of nutrient overenrichment resulting in the development of extensive algal blooms. |

Thursday, October 25, 2012 Super phosphates – not in mink feed! http://www.novascotiaminkblog.com/2012/10/superphosphates-not-in-mink-feed.html "I’d
like to help set the record straight.
Superphosphate is not put in feeds that I'm aware
of. I'd be very surprised to find someone trying
it. It is a chemical fertilizer for crops and
gardens.
However,
phosphoric
acid is a
common additive, used as a preservative and to
reduce pH at certain times of the year."

3. Evaluation of Sodium Bisulfate as
a Replacement for Phosphoric Acid in a Conventional Mink
Ranch Diet http://www.furresearch.org/secure/FAR/Feb11.pdf Phosphoric acid has been used
in conventional mink ranch diets and in commercial
mink and fox pellet formulations for preservation of
feed, for prevention of urinary calculi in mink and
fox and to reduce the incidence of “wet belly” disease
in mink. The recommended level of inclusion is 1.0% of
75% feed-grade phosphoric acid in conventional ranch
diets employing 15 to 20% fortified cereal. Prevention
of urinary calculi composed of magnesium ammonium
phosphate by addition of phosphoric acid to the diet
is accomplished through a reduction in urinary pH.

Phosphates and superphospahtes: little differance
(S) Most water pollution from industrial farms results from the storage and disposal of animal waste. Industrial livestock farms store manure and other farm wastes in gigantic tanks known as “lagoons” which can hold millions of gallons of manure and urine. Unfortunately, these lagoons often leak and—during large storms—they may rupture or simply overflow. When this happens, the environmental damage can be devastating, as raw manure is up to 160 times more toxic than raw municipal sewage. FLeaking lagoons also release antibiotic residues and harmful bacteria that can leach into water supplies. (source) Where have all the phosphates gone? http://www.gov.ns.ca/nse/surface.water/docs/Yarmouth.Area.Lakes.Water.Quality.Assessment.2012.pdf minitweets50ug=.05mg=.5ppm ---- 100ug=.1mg=1ppm *Uses of Phosphoric acid H3PO4 In feed it is used to absorb moisture that could cause food to rot which could cause botulism. Inorganic phosphate ion is naturally found in the body. It is excreted mainly in the urine http://www.phosphoric-acid-supplier.com/phosphoric-acid.html *Canadian research examines removal of phosphorus from manure. *According to some researchers, Earth's phosphorus reserves are expected to be completely depleted in 50–100 years and peak phosphorus to be reached in approximately 2030. Pdf(http://pdf.usaid.gov/pdf_docs/PNADW835.pdf) Freshwater systems:
Nutrient-induced production of aquatic plants
in freshwater has several detrimental
consequences:
1. Algal mats, decaying algal clumps, odors and discoloration of the water will interfere with recreational and aesthetic water uses. 2. Extensive growth of rooted aquatic macrophytes will interfere with navigation, aeration, and channel capacity. 3. Dead macrophytes and phytoplankton settle to the bottom of a water body, stimulating microbial breakdown processes that require oxygen. Eventually, oxygen will be depleted. 4. Aquatic life uses may be hampered when the entire water body experiences daily fluctuations in dissolved oxygen levels as a result of plant respiration at night. Extreme oxygen depletion can lead to death of desirable fish species. 5. Siliceous diatoms and filamentous algae may clog water treatment plant filters and result in reduced time between backwashing (process of reversing water flow through the water filter in order to remove debris). 6. Toxic algae (occurrence of "red tide") have been associated with eutrophication in coastal regions and may result in paralytic shellfish poisoning (Mueller et al., 1987). 7. Algal blooms shade submersed aquatic vegetation, reducing or eliminating photosynthesis and productivity (Dennison et al., 1993; Batiuk et al., 1992). |
