Dust monitoring results released from Environment Canterbury

The results of the Environment Canterbury monitoring programme at Yaldhurst have been released, in a report made available on Friday 22 June. The report focussed on dust which could have adverse health effects, in particular respirable crystalline silica dust (RCS). The report concluded that there was no serious public health risk from quarrying activities, and that the results were well below the international guidelines for RCS.

Background

The report was triggered by complaints from residents who live near the Yaldhurst Rural Quarry zone, who were suffering from adverse health effects, which they considered were caused by dust from the neighbouring quarries (in particular from RCS).
