Physical and chemical hazards

Nitric acid is a corrosive liquid. Non-flammable, fire

hazardous liquid. In contact with combustible materials

causes their self-ignition. Being heated, decomposes with

formation of toxic vapours (NOx). Reaction with water is

followed by heat emission (exothermic reaction) and

generation of corrosive vapours.

Health hazards Causes severe burns of all parts of body. Affects central

nervous system, vascular system and respiratory system,

organs of vision, liver, skin, teeth, gastrointestinal tract.

Nitric acid vapours are corrosive, hazardous in case of

inhalation, can cause pulmonary edema, which can lead to

lethal outcome. Nitric acid vapours cause odontatrophia,

conjunctivitis and affect eye cornea.

Inhalation: coughing, difficulty of respiration, dyspnea,

pulmonary edema, conjunctivitis, eye cornea damage.

Delayed pulmonary edema may develop.

Ingestion: burn of oral cavity, throat and gastro-intestinal

patient must be under the care of physician for at least 48

hours after exposure, as development of delayed pulmonary

edema is possible.

5 Fire-fighting measures

Suitable extinguishing media Dry powders, carbon dioxide, water spray for deposition of

vapours.

Extinguishing media not to be

used

Directed waterjet.

Specific hazards Toxic oxides of nitrogen (NOx) release in case of

decomposition.

Danger of explosion in case of interaction with strong

reducing agents, metals, as the reaction is accompanied by

release of hydrogen, capable of forming explosive mixtures

with air.

Hazardous thermal

decomposition and combustion

products

Decomposition may liberate nitric acid and toxic nitrogen

oxides (NOx).

Special fire fighting procedures Stay upwind during nitric acid extinguishing. Cool down

the containers with nitric acid by water spray. Avoid

entering of water into containers. Nitric acid vapours should

be absorbed by spray water or water mist. Enter the fire

area, wearing fire-protective clothing and self-contained

breathing apparatus.

Special protective equipment for

fire-fighters

Wear full fire-protective clothing and self-contained

breathing apparatus.

6 Accidental release measures

Personal precautions Isolate the hazard area. Exclude the presence of persons,

not participating in rescue operation Avoid entry into

danger area. Remove all possible sources of ignition. If

necessary, localize the spilled liquid by digging around. The

spills should be cautiously neutralized by lime or

carbonates.

Use explosion-proof equipment and explosion-proof tools.

Avoid contact with the substance. Apply self-contained

breathing apparatus and fire-protective clothing. Evacuate

people, taking into account toxic gas cloud travel direction,

choosing up-wind location of people. Organize medical

examination for people from danger area. All competent

authorities should be informed about the incident in

accordance with legislation requirements.

Environmental precautions Prevent from leaks of substance. Do not allow substance to

enter soil, water and sewage systems

In case of substance discharge into water-supply sources,

inform regulatory authorities immediately, stop supply and

use of water.

Use water curtain to reduce spreading of nitric acid

vapours.

Methods for cleaning up Neutralize cautiously using lime or carbonates. Do not use

saw-dust or other combustible materials to collect nitric

acid spills. The impregnated material is removed from the

room and disposed in accordance with valid legal waste

regulations. The place of nitric acid spill is washed with

water. Water is collected by explosion proof pumps into

hermetically closed container, and supplied for disposal

according to valid legal waste regulations.

It’s prohibited to discharge waste nitric acid into sewage

system. It should be collected into a hermetically closed

container and dispose according to valid legal waste

regulations.

Remarks Cleaning of the pollution zone should be done only by

specially trained personnel.

Note: see section 8 for personal protective equipment and section 13 tor waste disposals.

7 Handling and storage

Handling Use hermetical process equipment and transportation

packing. Ventilation of processing area, effective exhaust.

Handling nitric acid is not allowed if ventilation is out of

order. Observe all fire-fighting measures (no smoking, do

not handle with naked flame and remove all possible

sources of ignition). The place of operations with nitric acid

should be provided with good grounding. Use explosion-

proof electrical equipment. Use recommended personal

protective equipment and observe instructions to prevent

inhalation, contact with skin and eyes (see section 6).

Avoid leak to the environment. Control the content of

nitric acid vapours in the air of working area. Nitric acid

vapours are heavier than air, so they can mass up

underneath.

When nitric acid is being diluted, add acid in water to avoid

splashing. Cisterns and barrels should be filled up to not

more than 90%. Bottles- to not more than 95%.

Storage The design of storage facilities and containers for nitric acid

should comply with the requirements of regulating

authorities. Storerooms should meet the requirements for

the fire safety of constructions and electrical facilities and

should be in conformity with valid regulations. The storage

facilities should be located downwind of prevailing wind

direction in relation to the major inhabited locality.

Store in hermetic sealed containers, excluding ignition and

contact with personnel in a cool (temperature of storage

shouldn’t exceed 40ºС), well-ventilated place with

effective exhaust, away from heat and any sources of

ignition. Prevent nitric acid from contact with direct

PNEC water:

PNEC Assessment factor Remarks/Justification

Qualitative approach pH approach Nitric acid is a strong acid (pK= -1.4), which dissociates in water into its respective

ions H+ and NO3-. The protons can affect the pH level of the water body thus entailing

toxic effects to aquatic organisms. The increasing nitrate concentration is judged to have a minor effect on aquatic organisms compared to the effect of pH because LC50

values for acute fish tests with nitric acid are 1 to 2 orders of magnitude lower

compared to LC50 values for sodium or ammonium nitrate. Moreover, the EU limit value of 50 mg NO3-/L (0.8 mmol NO3-/L) for water corresponds to a low pH of 3.1

when all nitrate comes from nitric acid, which is below the pH at LC50 for fish. The

pH change due to anthropogenic nitric acid addition is influenced by the natural pH and buffer capacity of the receiving water, which both can vary significantly among

different aquatic ecosystems. Therefore, a generic pH threshold as derived from single–

species toxicity data in standard aquatic media is not relevant for all aquatic

ecosystems. Moreover, organisms are able to adapt to specific conditions, with pH

ranges of tolerance for the major taxonomic group (algae, crustaceans, fish) commonly

reported to vary between 6 and 9 (A comparable statement can be found in the NaOH

RAR (2007) as also based on pH approach). The proposed approach is confirmed by the available toxicity data. The available data for acute effects to fish, identify LC50

value at pH 3.5 (Ellgaard and Gilmore, 1984) and 4.0 (Swift and Morgan, 1983). An

assessment factor of 100 is deemed appropriate in order to take into account the pH effect of nitric acid emitted to the water compartment and the threshold value can be

therefore calculated to vary between pH 5.5 and pH 6. A pH value of 6 is selected as

the threshold value for the chemical safety assessment of nitric acid.

PNEC sediment:

PNEC Assessment

factor

Remarks/Justification

Qualitative approach Based on the available data it is not considered useful to derive a PNEC for nitric acid in

sediment because nitric acid is an acidic substance that dissociates in water into H+ and

NO3-. High water solubility indicates that nitric acid will be found predominantly in

aquatic environment and will not adsorb on particulate matter or surfaces. The equilibrium

partitioning approach cannot be successfully used to derive a threshold value for strong acids that affect organisms through their effect on pH because the fate and behaviour of the

protons (i.e. pH buffering capacity) is mainly controlled by precipitation and dissolution of

minerals.

PNEC soil:


Qualitative approach

When spilled onto soil, nitric acid will infiltrate according to the soil viscosity. During

transport through the soil, nitric acid will dissolve some of the soil material, in particular,

carbonate based materials (OECD SIDS Nitric acid Assessment Report, 2008; HSDB, 1999). Leaching of acids from soil depends on the water amount present in the soil. The

nitrate released from nitric acid is taken up by plants or denitrified by microorganisms to

nitrogen or nitrous oxide.

PNEC sewage treatment plant:

Value Assessment

factor Remarks/Justification

Nitric acid hazard is mainly caused by the increase of H+ concentration (i.e. pH effect)

released during dissociation. Because STP conditions, such as pH, are regularly monitored

and adjusted, neither strong acid or strong basic effects can occur in STP and it is therefore not relevant to derive a PNEC STP for nitric acid.

PNEC oral:


Nitric acid has no potential for bioaccumulation. Nitric acid is an inorganic compound,

miscible with water and highly soluble in water. Nitric acid dissociates in water into H+

and NO3-, therefore bioaccumulation of nitric acid itself is not relevant and does not

require further assessment. If released to air, nitric acid immediately reacts into nitrogen

oxides. When deposited to soil, nitric acid also dissociates into protons and nitrate ions. The excess protons can dissolve some soil materials as carbonate based materials and the

nitrate is partly taken up by plants.

Engineering measures

General and local ventilation as appropriate, providing nitric

acid vapours concentration below maximum allowable values,

effective exhaust, process automation, equipment sealing. Use

of explosion-proof electrical equipment.

Any room, where contact with eyes or skin may occur, should

be equipped with safety showers and eye-wash facilities.

Hygienic measures

Observe personal hygienic regulations. Do not eat, drink or

smoke during work! Wash hands before and after eating,

smoking and using toilet and when work is completed.

11 Toxicological information

Toxicokinetics, metabolism

and distribution

Absorption factors of 100% are proposed for oral, inhalation

and dermal absorption. For route-to-route extrapolation starting

from oral data, an absorption factor of 50% is proposed as a

worst-case assumption. Nitrate can be reduced to nitrite by both

enteric bacteria and mammalian nitrate reductase activity. Nitric

acid is not considered to have bioaccumulative potential as

nitrate is highly soluble in water and rapidly excreted via the

urine.

Acute effects Nitric acid causes serious skin burns and eye damage. No

relevant study available but test is not required due to the well

known corrosive properties of nitric acid.

Eyes: burn, cornea damage may lead to irreversible effects-

blindness

Inhalation: vapours of nitric acid cause irritation if respiratory

tract mucous membranes (nose, throat, lungs), that can turn into

cough, bronchial edema and pulmonary edema. Pulmonary

edema may be delayed and asymptomatic and lead to death.

Repeated or long inhalation of nitric acid vapours leads to

alterations of lungs function and destroy of teeth.

Chronic toxicity Repeated dose toxicity: No reliable data available.

Nitric acid has been identified as corrosive, which could lead to

possible future systemic effects. However no evidence of this

was identified in the repeated dose studies.

Carcinogenicity Two unreliable studies were identified for nitric acid

carcinogenicity. These studies were of limited value for

addressing the carcinogenic potential of the test substance due

to the short duration of exposure and the inadequate reporting of

the study design and results.

Nitric acid is not classified as carcinogenic by IARC

(International Agency for Research on Cancer).

Mutagenicity From the results obtained on nitric acid, sodium and potassium

nitrates and due to their structural similarities with nitric acid, it

is possible to conclude that nitric acid is not expected to cause

genetic toxicity.

Reproductive toxicity There is no evidence, that nitric acid presents danger for

development of toxicity.

NOAEL (oral): 1500 mg/kg bw/day.

12 Ecological information Ecotoxicity Nitrogen is an important nutrient in ecosystems: it is essential

nitrate ion NO3- and the hydronium H3O+ under environmental

conditions. Once released in the environment, it may be

deposited in water, soil and vegetation.

When spilled onto soil, nitric acid will infiltrate according to the

soil viscosity. During transport through the soil, nitric acid will

dissolve some of the soil material, in particular, carbonate based

materials. The nitrate released from nitric acid is taken up by

plants or denitrified by microorganisms to nitrogen or nitrous

oxide.

Because of the quick dissolution nitric acid undergoes once in

contact with water, when nitric acid is applied as fertilizer, very

low pH values can be attained. The acidity will then gradually

diffuse into the soil surrounding the band.

In a view of acidity, (рН –factor), nitric acid may be harmful to

water bodies

Nitric acid exposed to air will result in nitrogen oxides release

(mainly NO2 and NO).

Avoid entry into sewage collector or water supply sources.

Acute ecotoxicity:

Median lethal pH Fish (Lepomis macrochirus) 96h 3-3.5

Median lethal pH Fish (Oncorhynchus mykiss) 96h ca. 3.7

Long-term toxicity:

Fish.

Nitric acid will dissociate in the environment into its ions: H+

ions and nitrate ions. The H+ ions will cause a pH decrease, but

in the aquatic environment the net pH decrease will be limited

due to buffering. At environmental pH level (i.e. pH 6-9) ,

exposure to nitric acid comes down to exposure to nitrate ions.

Therefore, for long-term toxicity assessment, can be used the

data, obtained from sodium nitrate study, which also dissociates

in the environment into its ions. The three-months study on

juveniles and larvae of the marine clownfish showed a NOEC of

97.8 mg NaNO3/L (or 71.3 mg nitrate/L).

Aquatic invertebrates.

The study showed that nitric acid concentrations causing a pH

outside the pH range of 6-9 can cause adverse effects to

reproduction of daphnids.
