Environmental Risk Classification

Predicted Environmental Concentration (PEC)

PEC is calculated according to the following formula:

PEC (μg/L) = (A*109*(100-R)) / (365*P*V*D*100) = 1.5*10-6 * A (100-R)

PEC = 0.0036 μg/L


A = 23.914 kg glyceryltrinitrat (total sold amount API in Sweden year 2016, data from QuintilesIMS).

R = 0 % removal rate (due to loss by adsorption to sludge particles, by volatilization, hydrolysis or biodegradation)

P = number of inhabitants in Sweden = 9 *106 

V (L/day) = volume of wastewater per capita and day = 200 (ECHA default) (ECHA 2008)

D = factor for dilution of waste water by surface water flow = 10 (ECHA default) (ECHA 2008)

Predicted No Effect Concentration (PNEC)

Ecotoxicological studies


EC50 96 h (growth rate) = 0.4 mg/L (Pseudokirchneriella subcapitata, method unknown) (Japanese Ministry of the Environment)

Crustacean (Daphnia magna):

Acute toxicity

EC50 48 h (immobilization) = 32.0 mg/L (method unknown) (Japanese Ministry of the Environment)

Fish (Lepomis macrochirus, bluegill):

Acute toxicity

LC50 96 h (lethality) = 1.67 mg/L (method unknown) (Japanese Ministry of the Environment)

PNEC derivation:

PNEC = 0.4 μg/L

The PNEC (μg/L) is based on the lowest EC50/1000, where 1000 is the assessment factor used if acute data for 3 trophic levels is available. The EC50 for green algae has been used for this calculation since it is the most sensitive of the three tested species.

Environmental risk classification (PEC/PNEC ratio)

PEC/PNEC = 0.0036 μg/L / 0.4 μg/L = 0.009, i.e. PEC/PNEC ≤ 0.1 which justifies the phrase "Use of glyceryltrinitrate has been considered to result in insignificant environmental risk."


Sewage treatment plants:

53.6 % loss of nitroglycerin (30°C, 5 days, activated sludge inoculum, shake-flast test) (non-standard method)

92.2 % reduction of nitroglycerin (room temperature, 84 hours, continious bench-scale activated sludge apparatus) (non-standard method)

100 % loss of nitrate esters (chemostat, continuous culture, aerobic system, 8-15 hours) (non-standard method) 

100 % mineralization (mixed cultures, anaerobic digester, 4 days, digester sludge amended with glucose) (non-standard method)

River water and water-sediment systems:

100% (13 days, river water and river water/sediment microcosms)

Half-life = 1 hour

Nitroglycerin and other aliphatic nitric acid esters undergo aerobic biodegradation readily via successive removal of nitrate groups to isomeric derivatives (Rendic S et al; 1995). Contrary to some earlier reports that it was recalcitrant to biodegradation, nitroglycerin proved to be readily biodegradable in batch and continuous tests. Results of the shake flask test that was run at 30 deg C with an activated sludge inoculum showed a 53.6% loss of nitroglycerin in 5 days. In a continuous bench-scale activated sludge apparatus, a mean reduction of 92.2% was obtained. The apparatus was run at room temperature and the residence time was 84 hr. 1,3-Dinitroglycerol and 1,2-dinitroglycerol were identified at intermediate stages of the process, but they were also essentially absent from the effluent. The third experiment employing a chemostat, a continuous culture, aerobic system with no solids recycling, was designed to simulate a plant where propellant wastes would be treated. After a 8-15 hr detention period, no nitrate esters were detectable in the effluent. It was found that nitroglycerin is not suitable as a source of carbon and nitrogen so nutrients are essential. It was speculated that the earlier experiments which showed nitroglycerin to be recalcitrant were conducted using concns of nitroglycerin that were toxic to the microorganisms (Wendt TM et al; 1978).

Complete mineralization of nitroglycerin (350 umol/l initial concn) was achieved within 4 days utilizing mixed cultures and an anaerobic digester, using digester sludge from a municipal wastewater treatment plant amended with 2,000 mg/l of glucose. Without glucose amendments, the complete mineralization of nitroglycerin took about 25 days in the digester (Hristodoulatos C et al; 1997).

Nitroglycerin, present at 16 mg/l, was rapidly degraded in a sequencing batch reactor using mixed liquor from an industrial wastewater facility and a domestic wastewater treatment plant, with 1,2-dinitroglycerol and 1,3-dinitroglycerol as the initial products (Accashian JV et al; 2000)

Nitroglycerin (10 ppm initial concn) was completely biodegraded in 13 days using river water and river water/sediment microcosms obtained from a river near a munitions facility in Virginia. Pure cultures isolated from river water and sediment near a munitions factory in Virginia degraded nitroglycerin. The first-order rate constant was 0.60 hours-1, which corresponds to a half-life of about 1 hour (Spanggord RJ et al; 1980)

Justification of chosen degradation phrase:

Based on the information presented above from sewage treatment plant and river water and water sediment system studies, the following degradation phrase is chosen: ‘Glyceryltrinitrat is degraded in the environment’.


Bioconcentration factor (BCF):

BCF = 5 (method unknown) (Hazardous Substance Database)

Partitioning coefficient:

Log Kow = 1.62 (method unknown). (Hazardous Substance Database)

Justification of chosen bioaccumulation phrase:

Since BCF < 500 and log Kow is < 4, glyceryltrinitrate has low potential for bioaccumulation.

Excretion (metabolism)

Nitroglycerin is rapidly metabolised by glutathione-dependent organic nitrate reductase in the liver. In addition, and probably more importantly, in vitro studies have shown that the human erythrocyte is also a site of biotranformation via a suphydryl-dependent enzymatic process and interaction with reduced haemoglobin.
