This report presents the first interim Environmental Quality Criteria (EQC) designed to help protect the petroglyphs of Murujuga. The initial Interim EQC proposed in this report are preliminary Guideline and Standard values based on controlled exposure studies and field observations to date.
More work will be undertaken to understand the relative contributions of NO2 and SO2 in isolation, as well as consider the microbiome and interactions with other species such as particulate matter.
The interim EQC presented here are intended ultimately to be used as part of an ongoing monitoring program to ensure the environmental values are protected. The interim EQC will be updated following completion of the third and fourth years of research studies.
