Sources, Compositions, and Health Risks of PM2.5-bound PAHs at the Rural Area along with the “Coal to Gas” Law
Published 2022-12-01“…Here, we deployed an intensive observation in winter of 2020 at a rural site in the central area of the Beijing-Tianjin-Hebei (BTH) region. A positive matrix factorization (PMF) model and an incremental lifetime cancer risk (ILCR) model were utilized to examine the PAH sources and health risks. …”

Adjustment of the Yellow River Water Allocation Scheme Based on Unused Water Permits
Published 2022-01-01“…Adjustment of the Yellow River Water Allocation Scheme (“Scheme 1987”) is vital for the water resource management of the Yellow River Basin and is a good example to explore the method of river water allocation adjustment.Most researchers analyzed government adjustment methods while market adjustment methods were not fully discussed.This paper put forward a new water allocation scheme based on unused water permits.In the new scheme,assignable water resources will be calculated by subtracting ecological water needs from changed river runoff.Unused water permits will be canceled and returned to the Yellow River Basin Commission and the canceled water permits will be sold to different provinces by auction.The water allocation ratio of provinces will be calculated by the sum of left permits and bought permits.The canceled water permits of Shaanxi Province,Shanxi Province,Henan Province,and Hebei Province and Tianjin City were calculated to be 662,1 417,154,1 362 million m<sup>3</sup> respectively.Cancellation of water permits will have a greater impact on Shanxi Province than other provinces.The loss of these provinces should be compensated with the investment of the central government and the fund of water permit auction.This new water scheme adjustment method can provide a novel idea for river water allocation adjustment.…”

Effect of the Subsurface Drain Parameters on Water-salt Transport Based on HYDRUS-2D
Published 2021-01-01“…In order to study the effect of the subsurface drain parameters on water-salt transport,this paper performs the field test in typical experimental area selected from Binhai New Area of Tianjin,China,calibrates and verifies the simulation effect of HYDRUS-2D by experimental data,and simulates the water-salt transport under different subsurface drain parameters by the validated model.The simulation results show that:HYDRUS-2D can well simulate water-salt transport of soil under the condition of subsurface drainage.When the depth of subsurface drains is kept unchanged,the larger the subsurface drains is spaced,the higher the water and salt are contained in the soil after leaching.When the spacing of subsurface drains is kept unchanged,the deeper the subsurface drains are,the lower the water and salt are contained in the soil after leaching.Among the 12 simulated subsurface drain scenarios,under the combined parameters of 140 cm depth (maximum) and 300 cm spacing (minimum),the salt of soil profile is 0.47~7.81 g/kg (minimum).Therefore,when the subsurface drain technology is applied to the improvement of saline-alkali soil,it is necessary to reduce the spacing of the subsurface drains or increase the depth of the subsurface drains to improve the leaching effect.…”
