Balancing economic growth, resource conservation, and atmospheric environmental protection has topped the agenda of academics and policy makers. The article takes the panel data of 37 Chinese industrial sectors from 2003 to 2016 as the research object to explore the impact of atmospheric environmental regulation on industrial total factor productivity and the possible path of capital intensity. Furthermore, to analyze the possible industry heterogeneity of the above results, the article classifies the industrial sectors into heavy polluting industries and light polluting industries, based on their air pollution emission intensity. The key discoveries of this study are as follows (1) Generally, the regulation of atmospheric environment has a significant inhibitory effect on industrial total factor productivity. However, if measured by industry group, atmospheric environmental regulation has a significant inhibitory effect on industrial total factor productivity in the light polluted industry group, while in the heavy polluted industry group, the impact is less significant. (2) Across all the industries and especially the light polluted industry group, the capital intensity is a partial intermediate variable of the influence of atmospheric environmental regulation on industrial total factor productivity, but the mediating effect is not significant in the heavy polluted industry group. Finally, policy suggestions are given from the following three aspects promoting accurate industrial governance, selecting environmental regulation methods and improving supporting policies, which provide practical and feasible solutions for improving the current atmospheric environment governance and promoting the improvement of industrial total factor productivity.This work presents a novel catalyst preparation method and the optimization of operation conditions for an effective NO3- conversion with a high selectivity and stability that guarantee water quality for human consumption. Catalytic reduction of NO3- and NO2- was carried out with Pd supported on In2O3 under mild operation conditions (25 °C, 1 atm) with H2 and CO2 as reducing and acidifying agents, respectively. The catalyst was used in batch experiments showing the suppression of NO2- accumulation and low NH4+ selectivity at acid pH. Long-term experiments were carried out with Pd on γ-Al2O3 spheres covered with In2O3. This catalyst presented a high stability during more than 700 h. A concentration of NO3- below 50 mg/L was achieved, producing less than 0.5 mg/L of NH4+ as reaction by-product by a strict limitation of the H2 fed and controlling several operating conditions.The status of technical efficiency (TE) of environmental protection enterprises is crucial to the sustainable economic development. Based on the micro-survey data of China's environmental protection enterprises from 2003 to 2013, through a systematic calculation and comparison about TE level under stochastic frontier analysis, this article investigated the distribution characteristics and heterogeneous sources of them comprehensively and found that first, there are wide-ranging technical efficiency differences among sub-sectors, ownership, and regions within China's environmental protection industry, and this type of heterogeneity was significantly interfered by the institution and policy environment. Second, there is obvious scale economy effect and no scope economy effect in the TE distribution of China's environmental protection enterprises, and their TE level has a positive response to management improvement and competition enhancement, but has a negative feedback on heavy asset expansion and debt-driven growth mode. find more Third, the overall TE levels of non-state-owned enterprises are higher than that of state-owned enterprises; the overall TE levels of enterprises located in the eastern provinces are higher than those of enterprises located in the central and western provinces. Fourth, reducing tax burdens of environmental protection enterprises is more effective to promote their TE level than providing governmental subsidies directly. Therefore, to promote the quality of the development for China's environmental protection industry, it is necessary to emphasize the market mechanism. Based on the market power, we should accelerate the industry integration, cultivate the market demand, and promote market competition. Furthermore, the government should also need to design a targeted support system and differentiated policy arrangements for the development of environmental protection enterprises.Atmospheric radioactive airborne released from several natural and artificial sources can travel for long distances and disperse in different directions. Both the physical and chemical characteristics of the atmospheric aerosols control this movement. The concentrations of 210Pb, 210Po, 7Be, 40K and 137Cs radionuclides in the ground surface air were determined in three particle sizes (2.4-10.2, 0.73-2.4 and less than 0.73 μm). High-volume air samples were collected from five different locations representing the five governorates of Kuwait using high-volume air samplers connected to a five-stage cascade impactor. The radioactivity concentrations of almost all fallout radionuclides were concentrated on the fine particle size fractions. The cosmogenic 7Be radioactivity level in all locations was relatively comparable and varied between 1.16 and 18.38 mBq/m3, with a geometric mean value of 6.80 mBq/m3. 137Cs was infrequently recorded with concentration varied between 4 and 14.3 μBq/m3. The geometric mean levels of the 210Po and 210Pb were 0.899 mBq/m3 and 1.03 mBq/m3, respectively, indicating that anthropogenic sources likely enrich 210Po. 40K was concentrated on large particle size fractions with a geometric mean value of 2.34 mBq/m3, reflecting the effects of the local dust sources. It was concluded that the radiological hazards due to airborne radioactive inhalation are low and can be negligible, where the annual estimated effective dose is about 64.0 μSv. The radioactive airborne measurements compose the base of estimating the aerosols residence time, resuspension rate of dust, soil redistribution and source apportionment, particularly the 210Pb and 210Po radionuclides.
