Causative agents are notified to us through the shield scheme, through Oasys and some we hand enter ourselves. When a new agent is notified to us we categorise it and add a few details where possible. Some agents are badly spelt or are an alternative name of an existing agent and these are grouped together where possible.
More than 400 agents have been identified as causes of occupational asthma, many of which are biological agents. If you don't find an agent in the list below, please search in the references section.
Some agents here are "under construction" and we are still working out what to say about them. These are not clickable.
