Copper toxicity > Signs and symptoms: https://en.wikipedia.org/wiki/Copper_toxicity#Signs_and_symptoms https://en.wikipedia.org/wiki/Copper_toxicity#Signs_and_symp... : > The US EPA lists copper as a micronutrient and a toxin. [11] Toxicity in mammals includes a wide range of animals and effects such as liver cirrhosis, necrosis in kidneys and the brain, gastrointestinal distress, lesions, low blood pressure, and fetal mortality. [12][13][14] The Occupational Safety and Health Administration (OSHA) has set a limit of 0.1 mg/m3 for copper fumes (vapor generated from heating copper) and 1 mg/m3 for copper dusts (fine metallic copper particles) and mists (aerosol of soluble copper) in workroom air during an eight-hour work shift, 40-hour work week. [15] Toxicity to other species of plants and animals is noted to varying levels. [11] A reasonable production process would need to contain and could probably reuse copper emissions
