In present China, continuing to control PM2.5 (particulate matter < 2.5 μm) and preventing the rise of O3 are most urgent environmental tasks in its air clean actions. Considering that NO2 is an important precursor O3, a comprehensive analysis around this pollutant was conducted based on real-time-monitoring data from Jan 2018 Mar 2019 11 prefecture-level cities Shanxi Province China. The re...

The geochemical characteristics of water produced from coalbed methane (CBM) wells contain rich information about the associated geology, environment, and production. This study was conducted in Southern Qinshui Basin, where samples were collected 10 typical CBM their ionic compositions quality parameters tested. differences chemical between different producing coal seams single-seam production...

There are fewer longitudinal studies from China on symptoms as described for the sick building syndrome (SBS). Here, we performed a two-year prospective study and investigated associations between environmental parameters such as room temperature, relative air humidity (RH), carbon dioxide (CO2), nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3), particulate matter (PM10), and health ou...

Transitional shale gas, rich in resources, is expected to be a practical contributor the increase gas reserves and production China. Its exploration prospect has been demonstrated by several wells Daning-Jixian block on eastern margin of Ordos Basin. In this paper, Lower Permian Shanxi Formation (P1s) Taiyuan (P1t) Basin were compared for organic geochemical parameters, revealing that overflow ...

At present, the Carboniferous-Permian shale gas in South North China Basin is still exploration stage, and understanding of microscopic pore structures, mineral composition hydrocarbon enrichment law marine-continental transitional reservoirs this area extremely limited. In paper, taking reservoir as an example, geological conditions accumulation have been systematically studied using a large a...

The coal-forming period is mainly Permian and Carboniferous in the North China coalfield, which one of main coal accumulating areas China. It characterized by high rank, abundant reserves, varieties. However, water outburst accidents originating from karst aquifers under seam floor have become a terrible disaster accompany with deep exploited progressively. Water inrush events limestone often o...
