Adverse human health effects
Phosphoric acid is classified as a corrosive substance which causes
burns.
Phosphoric acid causes tissue damage through direct chemical
action. Tissue proteins are turned into acid albuminates that can
dissolve in concentrated acid. Heamonoglobin is precipitated. As a
strong irritant it causes loss of tension in the nervous system.
Ingestion (swallowing) - phosphoric acid often eats away
oesophagus and stomach walls. The contact area is coloured
brown or black. Precipitated blood looking like coffee grounds can
be often found in stomach. Oesophagus epithelium can be partially
or completely exfoliated.
Eye contact - phosphoric acid can cause cornea exposure and in
more serious cases oedema and necrosis of deeper located tissues.
Skin contact - phosphoric acid causes burns that usually penetrate

the complete depth of the skin; the wound heal slowly
with scaring and inflammations.
Vapour inhalation - causes pulmonary oedema. Accompanying
physical symptoms are most often wheezing, low blood pressure
and quickened pulse. Haemoptysis and dyspnoea can persist for a
few weeks after a single exposure to acid vapours.
Vapours can cause damage to tooth enamel.
Chemical hazards
Phosphoric acid is a medium acid. At room temperature it is
lasting and chemically low-active; does not oxidise, tends to
condense strongly (polyphosphoric acids are created by
dehydration).
It is resistant to strong reducing agents at room temperature or
even at the temperature of up to about 350 - 400°C, at the
temperature of over 400°C it is easily reduced. At higher
temperatures the phosphoric acid is highly reactive with the
majority of metals and their oxides, and it affects even such
resistant oxides as silica.
Boiling phosphoric acid is highly corrosive for the majority of
practically applied metals and alloys, as well as for ceramics
which acid resistance decreases as the temperature and
concentration grow.
Concentrated and hot H3PO4 reacts with porcelain and platinum.
Adverse environmental effects
After entering the environment, phosphoric acid causes strong soil
and water acidification and is toxic for plants and animals.
Criteria for PBT or vPvB in accordance with Annex XIII of the
REACH Regulation do not apply to inorganic substances.
Phosphoric acid is not identified as a PBT and vPvB substance.

Avoid contact with eyes and skin. Thoroughly wash hands before
break and after work.
Technical measures: It is required to use adequate classical
exhaust ventilation in the way described in the annex to the safety
data sheet. The boundary value of professional exposure
applicable in Europe has to be observed. Use only acid-resistant
materials.
Do not inhale vapour. Never pour water or any water solutions to
tanks or containers with acids. Dissolution and neutralization
reactions are highly egzotermic in such cases. Avoid splashes.
Observe caution. Always add acid to water. Do not mix it with
inadequate materials (see subsection 10.5).
Keep in steel rubberised containers or in an acid-resistant steel
container placed in open air on concrete trays tiled with acid-
resistant tiles. Smaller quantities of acid can be kept in transport
packages in well-ventilated rooms or in open air or on concrete
trays tiled with acid-resistant tiles (accidental spillage protection).
Do not stack packages with the substance one on another. Observe
general rules concerning the storage of chemicals; close the
packaging for the time of not using the substances. Do not expose
the substance to direct influence of sunshine.
Do not store in temperatures close to the freezing temperature.
Avoid freezing of the substance (85% at +21,1 oC, 80% at +4,6
oC
and 75% at -17,5 oC; the actual point of freezing is again
unpredictable). After melting the chemical’s physical and
chemical properties recover.
Adequate materials: stainless steel, high-density polyethylene,
glass.
Collective storage is permissible only with materials of the same
hazard class.
Detailed information on specific end uses is contained in exposure
scenarios.
The exposure scenarios contained in annexes depict the most
disadvantageous conditions of human and environmental
exposure.

effects
As no acute toxicity hazard and no
systemic toxicity has been identified,
there is no requirement to derive acute
DNELs.
Phosphoric acid as such is not expected
to become systemically available in the
body. Once absorbed, phosphoric acid
is distributed widely in the body as
phosphate, which is an essential
element to organisms and its
metabolism in the human body is
regulated. Phosphoric acid can be
locally absorbed by ingestion,
inhalation and dermal contact but is not
expected to elicit a systemically toxic
effect.
Long term systemic
Inhalation
Acute local effects
A DNEL for acute toxicity should be
derived if an acute toxicity hazard
(leading to C&L) has been identified
and there is a potential for high peak
exposures (REACH Guidance
document R8, appendix R8 -8: Acute
toxicity). The substance is not
classified for acute exposure via
inhalation. In addition, no peak
exposure is warranted for this
substance. A European Short term
Occupational exposure limit
recommended from Scientific Expert
Group is available for phosphoric acid
and is STEL 15 min: 2 mg/m3. This
value is based on the Rushing
observation on phosphorus pentoxide to
the ACGIH TLV committee
Long term local
effects
A DNEL for long term inhalation,
workers has been calculated to be 2.92
mg/m³ on the basis of an OECD 422
study.
However, A European Long term
Occupational exposure limit (OEL)
recommended by the Scientific Expert
Group (SCOEL and HSE) is available
for phosphoric acid: 8 hour TWA: 1
mg/m3. This value is based on the
Rushing observation on phosphorus
pentoxide to the ACGIH TLV
committee. Nevertheless as this value is
more conservative it will be used in the
exposure assessment and determination
of the risk characterization ratio for
phosphoric acid.
No DNELs can be derived for dermal local effects as the
concentration limit for corrosivity of H3PO4 is 25%. The
concentration range of 10 -25% is established for irritation,
therefore calculation of a DNEL is not required due to protective
measures already in place.

Not

The predominant adverse effects of
phosphoric acid in aquatic systems are pH-
related effects, as a result of the acidic
nature of phosphoric acid. As phosphoric
acid is a triprotic acid it will dissociate up
to 3 times; releasing a phosphate anion
(H2PO4-, HPO4
2- or PO4
3-) and a H
+ ion at
each dissociation. The fate of the H+ ions
(and subsequently the resultant pH) will
depend on the chemical composition of the
receiving water body. The pH of the
receiving body can vary significantly
between different ecosystems and
geographical locations and also the pH
change as a consequence of anthropogenic
phosphoric acid is influenced by the
buffering capacity of the receiving water.
Changes in the pH of a water body can
have potentially toxic effects on the
endogenous aquatic organisms present.
However, the sensitivity of the organisms
to pH changes vary significantly according

to location or species (pH ranges of
tolerance for the major taxonomic groups,
fish, crustaceans and algae, are commonly
report to vary between pH 6.0 and pH 9.0).
The phosphate anions are not considered to
be toxic to the aquatic environment as
phosphate anions are naturally widespread
both in the environment and within
organisms and cells, and they are readily
assimilated as an essential nutrient by the
aquatic organisms. It is therefore not
considered appropriate to derive a PNEC
aqua on the basis of single-species
ecotoxicology data as the main risk factor
has been determined to be a phosphoric
acid related change in the pH of the
receiving water body rather than direct
toxicity of phosphoric acid to the target
organisms (in a laboratory study the test
media would be buffered to pH-neutral
thus sequestering the H+ ions and as such
no adverse effects would be expected).
In addition, pH-related effects are
considered to be of lower risk in marine
water due to its buffering capacity being
greater than that of freshwater.
PNEC STP Not
calculated
No data are available for STP
microorganisms. In water phosphoric acid
will progressively dissociate to phosphate
anions (PO43-) and hydrogen cations (H+).
The release of H+ ions will lead to a net
decrease in the pH of the receiving water
body. However, in the case of waste water
treatment plants, the pH levels are typically
adjusted to ensure a neutral discharge to
the receiving water and in order to prevent
pH-related inhibitory effects on the growth
of STP microorganisms. The neutralisation
of phosphoric acid would result in the STP
microoganisms being exposed to
phosphate. Phosphate is an essential
nutrient for activated sludge systems and
does not result in adverse effects. It is
therefore not considered appropriate or
meaningful to derive a PNEC STP for
phosphoric acid.
PNEC
sediment
(freshwater)
Not
calculated
No data are available for sediments.
Phosphoric acid will progressively
dissociate in water to give H+ and PO4
3-
ions. Due to its high water solubility and
low vapour pressure it is predicted that any
un-dissociated phosphoric acid will remain
in the water phase and will not absorb onto
particulate. The PO43-
ion is likely to
absorb onto sediment, however, PO43-
ions
are ubiquitous in the environment and are
found naturally in soil, water and sediment.

for maintaining a good chemical balance.
Toxicity to sediment organisms via this
route is not predicted and as such further
toxicity studies to determine a PNEC
sediment are not considered to be
scientifically justified.
PNEC soil Not
calculated
No data are available for soil organisms.
Phosphoric acid occurs naturally and
widely in low concentrations in soils, In
addition, phosphoric acid is widely used as
a plant fertiliser, either as such or as a
processing residue in superphosphates, and
as a soil stabiliser (through reactions with
aluminium molecules in clays). When
spilled on to soil phosphoric acid will
initially infiltrate downwards, but in most
cases it will dissociate to PO43-
and H+ ions
in the soil pore water, and/or react with
minerals present in the soil, in particular
calcium, iron and aluminium . Except in
very specific circumstances (acidic soils,
certain mineral soil types, very high dosage
of phosphoric acid) phosphoric acid will
not therefore penetrate beyond the surface
layer of soil and will not reach the
groundwater table. Phosphate loss to
surface water is usually related to run-off
or
erosion of soil particles, which carry the
attached phosphates. Accidental release of
significant quantities of concentrated
phosphoric acid into soil may cause soil to
expand as the phosphoric acid is
neutralised by the lime already present in
the soils resulting in calcium phosphate
minerals replacing calcium carbonate.
Phosphate ions released into soil are not
anticipated to result in toxicity to soil-
dwelling organisms as phosphate is an
essential nutrient. Toxicity to terrestrial
organisms via this route is only considered
to be as a result of localised pH changes; as
such it is not justified to further investigate
the effects of phosphoric acid on terrestrial
organisms as the potential effects are
highly variable according to location and
soil composition and a reliable PNEC soil
cannot be calculated. If phosphoric acid
does reach the groundwater table any
remaining phosphoric acid will dissociate
to PO43-
and H+ ions; the resultant ions may
be dispersed and diluted in the ground
water.
PNEC oral Not

Phosphoric acid is not considered to pose a
risk of secondary poisoning as it is not
anticipated to bioaccumulate. Phosphoric

Applied technical measures of control
It is necessary to:
- ensure proper ventilation in the workplace (and exhaust
ventilation in requires situations and according to the exposure
scenarios),
- in the direct vicinity of the direct exposure areas provide the
possibility of rinsing the eyes and taking a shower,
- use phosphoric acid in closed systems or open containers
equipped with locks,
- transport phosphoric acid by pipelines,
- fill/empty containers using automatic systems (suction pumps,
etc.),
- use a handling device /e.g. pincers, holders/ to avoid direct
contact with the acid and exposure by splashing oneself,
- observe principles of good practice.

Products:
At room temperature, phosphoric acid is lasting and chemically low-
active; it does not oxidise, tends to condense strongly
(polyphosphoric acids are created by dehydration).
Phosphoric acid is resistant to strong reducing agents at room
temperature or even at the temperature of up to about 350 - 400°C, it
is easily reduced at the temperature of over 400°C.
In contact with commonly known metals, it generates flammable
hydrogen, which can form an explosive mixture with air.
- high temperature,
- light
– contact of hot acid with metals
– nitromethane,
– alkalis,

– metal oxides.
Materials ineligible to be used jointly – iron and its compounds,
steel, aluminium and its compounds
Emission of toxic fumes POx, when heated up to high temperatures.
In case of hot acid reaction with contaminated metals, toxic gaseous
phosphine PH3 may be formed.

Causes burns of gastrointestinal tract in case of ingestion.
Health effects of acute exposure
Vapours and dusts above 5 mg/m3 cause conjunctiva congestion,
eyes pain and lacrimation; irritation of upper respiratory tract with
cough, burning sensations of throat, shortness of breath, larynx
oedema, haemoptysis.
Toxic pulmonary oedema may occur. Skin contamination with
solution causes burns with coagulation necrosis. Extensive burn may
cause shock. Eye contamination causes eyelid and conjunctivitis
burns. Poisoning through the digestive tract causes burns of oral
cavity mucosa, throat and gullet with risk of bleeding from the
digestive tract and shock.
Health effects of chronic exposure:
Inflammatory states of eyes and skin, chronic inflammatory states of
upper respiratory tract. Long-term exposition to acid vapours may
cause teeth erosion and later jaw necrosis. Irritation of bronchial
tubes and chronic cough as well as frequent episode of
bronchopneumonia may occur.

Basis for effect: growth rate.
Orthophosphoric acid is an inorganic substance, therefore there is no
need to test it for biodegradation capacity.
Not applicable to inorganic substances.
Phosphoric acid is not absorbed by soil. In most cases, it dissociates
into the ions of PO43-
and H+ in the water present in pores of the soil
and/or reacts with minerals present in the soil, particularly calcium,
iron and aluminium. Except for strictly specified circumstances
(acid soil, certain types of mineral soil, very large doses of
phosphoric acid), phosphoric acid will not penetrate into the
groundwater through the layer of soil.
As per the requirements concerning information and chemical safety
assessment, Chapter R.11: PBT Assessment, the PBT and vPvB
assessment criteria listed in Annex XIII to the Regulation are not

applicable to inorganic substances. Therefore, there is no need to
further test the PBT properties for phosphoric acid.
There are no available data on sediment and land toxicity. The
substance does not pose hazard to sediment or land organisms. An
increased concentration of orthophosphoric acid may case a
decrease of pH, which can have a local harmful influence on
organisms.
According to the criteria of European classification and labelling
system, there is no need to classify the substance as hazardous to the
environment.
13.Disposal Considerations:
13.1. Disposal:
13.2. Contaminated
packaging:
13.3. EC Waste Code:
Non-used, expired or contaminated phosphoric acid should not be
disposed of into sewage system. Dispose of waste product in
accordance with all government regulations.
Acid neutralization Phosphoric acid is neutralized with excess of
10% lime milk. It is completely clarified within 10 to 20 hours, but
the majority of solids are precipitated in 1 hour.
Phosphor disposal from water and drains: with precipitating
methods. Precipitating process is carried out in parallel to biological
treatment process in an aeration tank, where iron (III) salts and
optionally aluminium salts are added. Precipitated iron (III)
orthophosphate (FePO4) is a water- insoluble salt. Suspension of this
salt is absorbed in activated sludge and removed from treated
sewage.
Packaging, that can not be reused after cleaning must be disposed or
recycled in accordance with all federal, national and local
regulations.
Accepted waste codes/according to executory provisions of Act on
waste classified as hazardous.
