Assessment of the environmental impact of polymeric membrane production
This can be attributed to the impact of industrial PVDF production, the inputs for which are acetylene, hydrogen fluoride, lime (hydrated), and zinc. Hydrogen fluoride production in turn consumes fluorspar (97% purity) and sulfuric acid, and causes high emissions of sulfur dioxide into the air, leading to a strong impact on human toxicity.
