2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : coverage of silver nitrate can cause severe abdominal pain, vomiting, bloody and even gastrointestinal perforation. Can cause skin and eye burns. Long-term exposure to the commodities workers there will be a silver calmly systemic disease. Performance include : extensive skin pigmentation, were black or light blue and gray slate color; Silver calm eye caused eye damage; Silver calmly respiratory chronic bronchitis, etc.

two, toxicology information and environmental behavior

toxicity : it is a high drug category.
acute toxicity : LD₅₀50mg/kg (mice) are
Mutagenicity : DNA inhibited mice Maximum.
reproductive toxicity : rat poisoning lowest dose subcutaneous (TDL0) : 13,590 µ g / kg (male mating premedication a day), the right testis, epididymis and vas deferens influential. Mice were poisoning the lowest dose (TDL0) : 13,590 µ g / kg (male mating premedication 30 days), the testis and epididymis and vas deferens influential.

hazardous characteristics : inorganic oxidizer. Fuel fire case, will contribute to the fire. By heat decomposition, produce toxic nitrogen oxides.
combustion (decomposition) products : nitrogen oxides.

3. Emergency Monitoring Methods :
water rapid colorimetric tube (Japan system, nitrate)

4. Laboratory monitoring methods : acid
phenol two spectrophotometry (GB7480-87, Water) (nitrate)
ion chromatography (GB13580.5-92, Water) (nitrate)

5. Environmental standards :
China (GB5749-85) drinking water standard 20 mg / L (nitrate, N dollars)
China (GB/T14848-93) groundwater quality standards (mg / L) Class I 2.0; Type II 5.0; Class III 20; class IV 30; category V 30 above (nitrate, N dollars)
China (GHZB1-1999), surface water quality standard ( mg / L) Class I 10; Class II 10; Class III 20; class IV 20; category V 25 (nitrate, N dollars)

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing self-contained breathing apparatus to wear protective clothing. Do not direct contact with leakage. Rendering leakage with organic matter, reducing agents, flammable or metal powder contacts. A small leak : clean shovel collection in a dry, clean, covered containers. We could also use a lot of water rinse, diluted Add Water Wastewater System. Large Leak : recycling or collection shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : its possible exposure to dust, it is recommended to wear headgear electric powered air-purifying respirators and dust.
eye protection : Respiratory Protection has been protective.
physical protection : wear protective clothing 52,400.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, take a shower. To maintain good health habits.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed
eye contact with the skin : Did eyelid, mobile or saline irrigation water. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. If breathing is difficult, give oxygen. If breathing stop immediately mouth. Medical treatment. Fresh into
: oral intake of water were found to blues or egg white. Medical treatment.

fire fighting methods : fire-extinguishing agent : water, water mist and sand.
