摘要

AbstractHere, we sampled, tested, and analyzed heavy metals in soil obtained from green land in urban parks of Urumqi. Analysis included soil nutrient contents, particle size distribution, and health risks of heavy metal contaminants. Results showed that (1) organic matter and rapidly available phosphorus contents of all samples ranged from 6.07–58.34 and 6.52–116.15?mg/kg, with average values of 31.26 and 36.24?mg/kg, respectively; (2) silt (particle size 20–200?μm) comprised most of the particle distribution, accounting for 46.56–87.38% of the total, and the remaining particles were clay particles (0–20?μm) and sand (200–2000?μm); (3) calculations of HQing, HQinh, and HQdermfor eight heavy metals in three exposure patterns revealed values less than 1 for children and adults, indicating a level of carcinogenic risk for these heavy metals; and (4) calculating the carcinogenic risks of nickel, chromium, and cadmium through breathing pathway indicating no potential carcinogenic risk for any of the three. This research showed high soil nutrient content, providing fertile ground for plant growth in the green land of these urban parks. However, measures such as using sprinklers and increased green vegetation areas have been proposed to improve soil texture. This research can serve as a reference point for soil environmental protection efforts as well as future plant growth in urban Urumqi parks.]]>
