The index of geo-accumulation (I geo) and the pollution load index (PLI) were used to assess the pollution level and the U.S. Environmental Protection Agency (EPA) health risk model was implemented to determine the health risk for children. Besides, a geographic information system (GIS) was utilized to map the distribution characteristics of risk elements contents. The results showed that: (1) the mean content of Mn was the highest in each park. Besides, the mean content of all risk elements except As exceeded the background value of Shaanxi in each park. (2) The I geo of Co was obviously higher than other elements in each park and the highest (4.07) content occurred in the Xing Qing Park (XQP). The pollution condition of the Urban Sports Park (USP) was the most serious among the four parks. (3) The children were more susceptible to risk elements pollution through oral intake. (4) The hazard indices (HI) of non-carcinogenic risk (NCR) were within the safe range (HI = 1) and the carcinogenic risks (CR) of Cr, Ni, As and Co for children were within the receivable range in each park.

“…The nemero comprehensive pollution index method utilizes the average and maximum values of the single factor pollution index, which can highlight the impact of the maximum pollutant on the soil environment. It is an evaluation method that comprehensively reflects the soil pollution status polluted by various heavy metals [24][25], and its calculation formula is as follows:…”

Introduction China is rich in coal resources and is the world's largest coal producer and consumer. However, with the development and utilization of coal resources, a large number of wastes, such as coal gangue, mine water and fly ash, will be generated, causing pollution to the surrounding environment of the mining area [1-5]. In particular, under the action of spontaneous combustion, rainwater leaching and wind blowing, the trace heavy metal elements in the coal gangue and fly ash piled in the open air diffuse and migrate to the surrounding environment media, polluting the soil and leading to
