Hands touching fish or contaminated water, then touching mouth without handwashing in between

Jay - it's hard to answer your question without some more details. First of all, which specific exposures are you interested in? Are you referring to people doing fishing recreationally?

Could be ingestion, inhalation or dermal depending upon the process, and pollutants. For instance if one starts with the process of fishing, especially commercial, it could be from the handling of fuels and or emissions from combustion. One needs to know the daily cycle of fishing. Other routes could be from the ingestion of the caught fish by either commercial, recreational or subsistence fishing, and what they ingest-- whole fish or fillet? Dermal from fuels and or contaminated water. Stat by reviewing the process and then capture the source to exposure to outcome continuum.

I think, already it is well answered.

No sólo se tiene que analizar el proceso sino cómo realizan las tareas los pescadores, para poder definir grupos de exposición y rutas de exposición y absorción.
