SECTION 2: Hazards identification

2.1. Classification of the mixture

Hazard Class and Category Code Eye Dam. 1 Hazard Statement H318 Explanation of the phrases in section 16

Human Health effects Skin effect Longer contact may cause skin irritation. Eyes effect Longer contact may cause severe eye irritation. Swallowing There is no toxic effect when ingesting small amounts. Ingestion of a high amount leads to gastrointestinal discomforts. Inhalation High concentration of wafting dust may cause nose irritation and irritation of the upper respiratory tract and produce symptoms like sore throat and cough.

Environment Because fertilizers contain phosphates, in case of large scatterings unfavourable influence on environment is possible by eutrophication of inland waters (See section 12).

Persistence and degradability Nitric compounds pass through a natural cycle of nitrification or denitrification producing nitrogen or nitric oxides. Ammonium phosphates are transformed to calcium phosphates, ferrous phosphates or aluminium phosphates or they combine with organic soil matter. Phosphate compounds are absorbed mainly by clayey materials or they remain in a form of K+ ion in soil solutions. Main fertilizer components do not fulfill the P or vP criteria.

12.3. Bioaccumulative potential The fertilizer has a low potential. Main fertilizer components do not fulfill the B or vB criteria.

12.4. Mobility in soil + Ammonium NH4 is absorbed by soil particles. Phosphates, both dissolving in water and in citrate are transferred in soil only for a short period time, and then they are immobilized in soil. Potassium ion K+ dissolved in soil solutions is absorbed by clayey minerals; but in light soils, where these minerals are not present, a part of potassium can be rinsed.

12.5. Results of PBT and vPvB assessment Main fertilizer components are neither PBT nor vPvB substances.

12.6. Other adverse effects No data.

Transfer, loading and potential mixing of fertiliser products is likely to take less time per working day than the distribution of the fertiliser itself. Human factors not influenced MCP is corrosive to the eyes. During handling of the solid by risk management fertilizer products, exposure to the respiratory tract may occur. Potentially exposed body parts: skin, eyes. Other given operational Industrial workers conditions affecting workers The TRA tool predicts 8-hour TWA (Time Weighted exposure Average) airborne workplace concentrations of ≤ 5 mg/m3 for operations involving solid fertiliser products of medium dustiness. Use of fertiliser products with high dustiness may result in airborne workplace concentrations of ≤ 50 mg/m3. Professional workers The TRA tool predicts 8-hour TWA airborne workplace concentrations of ≤ 8 mg/m3 for operations involving solid fertiliser products of medium dustiness. Use of fertiliser products with high dustiness generally result in airborne workplace concentrations of ≤ 50 mg/m3 and, as described in operational conditions, workers performing activities under normal conditions should be exposed to the substance for less than 8 hours per day. However, the recommended risk management measures should be noted for outdoor spraying operations where airborne concentrations are predicted to be ≤ 200 mg/m3.

ERC 8a, 8b, 8d, 8e. Product Characteristics Solid and liquid fertilizer. Concentration of substance in The concentration of MCP in solid products and solutions mixture or articles (8-50%). Amounts used No data Frequency and duration of The use of fertiliser products may take place regularly, use for example once a week. Transfer, loading and potential mixing of fertiliser products is likely to take less time per working day than the distribution of the fertiliser itself. Environment factors not Loss to surface waters is thus usually related to surface influenced by risk run-off or erosion of soil particles, which carry attached management phosphates. As only small amounts of fertilizers are used by consumers, losses to surface water are regarded as negligible. Other given operational In most cases, users will transfer the fertiliser into conditions affecting distribution system (open vessel, irrigation system in environmental exposure greenhouses, watering can) and may need to dissolve or dilute the fertilisers in water before use, which may include active mixing either by hand or by use of sticks or other appropriate tools. Solid or diluted solution of fertiliser are applied to the ground at indoor sites (greenhouses, flower pots) or outdoor sites (gardens).
