      <subfield code="a">This study assessed the potential harmfulnessof particles in the lung by measuring their ability to elicit and maintain an inflammatory response and to damage lung tissue. It compared the inflammogenicity of two non-durable, biological particulates (Coryne-bacterium parvum and zymosan) with a pathogenic mineral dust (quartz) and a non-pathogenic dust (titanium dioxide) by dosing rats via the intratracheal route and measuring the consequent alveolitis</subfield>
