Yunnan Province is rich in mineral resources. Early mining, processing, metallurgy, and other mining activities produce three industrial wastes (waste water, waste gas, residue) causing environmental pollution. Considering the legacy site of a processing plant as research object, 21 sampling points study area 12 control periphery were set up to determine contents heavy metal(loid)s As, Hg, Cd, Cu, Ni, Pb, Cr soil. The spatial distribution was interpolated analyzed using Arcmap10.8, combined with single-factor index, Nemero Comprehensive Pollution Index, health risk assessment method for metal(loid) pollution status soil evaluated. acidic, largest average value elemental As percentages screening values. results composite index showed following trend: > Pb Cd Cu Ni Hg. mainly originate from metallurgy Hg combustion fossil fuels, while soil-forming substrates are main sources Ni. by most prominent element, whereas some areas also cannot be ignored prevent negative impacts on residents. It recommended remediate treat public events; therefore, this fills gap studying potential ecological risks, human assessments, exposure (oral ingestion, respiratory dermal contact).
