![]() ![]() Used in catalysts, pyrotechnic, pesticides, pigments, feed, fungicides, electroplating, anticorrosion and other industries and manufacturing copper compounds Used as analytical reagents and pesticides Used in pyrotechnic, pesticide, pigment, feed, fungicide, anticorrosion and other industries and manufacturing copper compounds When working, you should wear anti-virus masks, protective glasses and dust-proof overalls. Abdominal pain can be injected with 0.1% atropine sulfate 1 ml subcutaneously Eye irritation can be washed with water. In case of copper poisoning, gastric lavage can be performed with 0.1% K4 solution orally, or oral protein water and magnesium oxide laxative can be taken orally. The maximum allowable concentration of metal copper is 1 mg/m3 and copper oxide is 0.1 mg/m3. ![]() Dust and solution can irritate eyes and mucous membranes. Chronic poisoning is manifested by nervous system dysfunction, liver and kidney dysfunction, nasal septum ulcer and perforation, facial skin, hair and conjunctiva sometimes turn pale yellow-green or light black-green. oral administration of 0.2~0.5g copper salt can cause vomiting, l ~ 2 g can cause severe vomiting, and sometimes fatal poisoning can occur. when drinking water containing 44 mg/L copper, acute gastroenteritis occurs. In the harmful effects of excess copper, the hydrogen-sulfur reaction of Cu2 + with enzyme plays a decisive role. It is insoluble in water, soluble in ammonia and hot and concentrated sodium bicarbonate solution to become blue, and decomposes at 300☌.īasic copper carbonate can be used to make flares, fireworks, paint pigments, other copper salts, solid phosphor activators, pesticides, seed treatment and as fungicides and antidotes, and also used in electroplating.ĭissolved grams per 100ml of water: 1.462 × 10-4/20 ℃
