Summary

Agricultural activities discharge a range of contaminants into the air including greenhouse gases, ammonia, particulate matter, endotoxins, pathogens, volatile organic compounds, and odour as well as chemicals such as pesticides, herbicides, and fungicides. In New Zealand, livestock are known to be a significant source of greenhouse gases, however the potential public health risks associated with discharges to air from agriculture and agricultural practices in New Zealand have not been assessed. This review focusses on emerging issues related to agricultural activities that may be associated with risks for public health including particulate discharges to air from agriculture, and potential health risks associated with living near intensive livestock farms. This is a preliminary scoping review to evaluate the relevance of these issues in New Zealand and identify data gaps.
