![]() ![]() Do not blow dust off clothing or skin with compressed air. Wash thoroughly before eating or smoking. Do not allow dusts to accumulate as they may present a fire hazard. Use good housekeeping and sanitation practices. Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. See section 10 for more information on incompatible materials.Ĩ EXPOSURE CONTROLS AND PERSONAL PROTECTIONĮngineering Controls: Ensure adequate ventilation to maintain exposures below occupational limits. See section 8 for information on personal protection equipment.Ĭonditions for Safe Storage: Store in a cool, dry area. Provide adequate ventilation if dusts are created. Precautions for Safe Handling: Avoid creating dust as dusts may present a fire hazard. ![]() Place in properly labeled closed container for further handling and disposal.Įnvironmental Precautions: Do not allow to be released to the environment. Methods and Materials for Containment and Cleaning Up: Avoid dust formation. Isolate spill area and provide ventilation. Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Special Protective Equipment and Precautions for Firefighters: Full face, self-contained breathing apparatus and full protective clothing when necessary. May emit toxic metal oxide fumes under fire conditions. Dust from processing, dispersed in air in sufficient concentrations, and in the presence of an ignition source, is a weak dust explosion hazard. Specific Hazards Arising from the Material: This product does not present fire or explosion hazards as shipped. Unsuitable Extinguishing Media: Do not use water, carbon dioxide or halogenated extinguishers on molten or burning metal. Indication of Immediate Medical Attention and Special Treatment: No other relevant information available.Įxtinguishing Media: Use suitable extinguishing media for surrounding material and type of fire. Most Important Symptoms/Effects, Acute and Delayed: May cause irritation. Seek medical attention if symptoms develop or persist. Seek medical attention if symptoms develop or persist.ĮYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. SKIN: Remove contaminated clothing, brush material off skin, wash affected area with soap and water. Never induce vomiting or give anything by mouth to an unconscious person. INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. General Measures: No special requirements.

For a Cd concentration <0.2 mg kg dry wt. Soil Mn had significantly negative effects on rice Cd, accounting for >18% of the variance. The pH, which varied from 4.8 to 5.8, did not significantly affect rice Cd, whereas soil Cd and Zn had a significantly positive effect, together accounting for ∼14% of the variance. The proportion of rice samples with a Cd concentration greater than the Chinese rice Cd standard (0.2 mg kg dry wt. Slight increases in pH from 5.17 to 5.45 and MnO-AM from 66.3 to 82.1 mg kg were observed after liming. Effects of liming on rice Cd, soil pH, and amorphous Mn (MnO-AM) were then investigated. Lime (CaO) was spread at 1200 kg ha on the topsoil of a rice field during the tillering stage. Rice accumulates a high concentration of Cd in acid soils, even at low soil Cd levels. Very little has been reported on the effects of pH, Zn, and Mn on Cd uptake in rice ( L.) and their levels under field conditions. ![]()
