The image is rich with information and meaning. The caption could give more information about the place of the Ennore Creek - it's industrial history and its significance to the local people (such as the old woman), and about the interplay of different kinds of toxicity.
The blurred vertical areas on either side of the image lead me to wonder if the image cropped in order to focus attention on this woman. I defer to the ethnographer on this decision. I think this image is incredibly rich in ethnographic import.
