Phosphine containing hardmask
WebExposure to phosphine gas most commonly occurs by either: 1) inhalation of gas generated by external sources such as in the workplace or 2) when phosphide-containing pesticides are ingested and come into contact with water or moisture, thus generating phosphine gas. Severe poisoning in either scenario can result in multi-organ dysfunction (e.g ...
