However, eight of China's emissions allowances and natural gas markets demonstrate complex asymmetric dependence structures.The concentration of PAHs among raw and cooked meat products (sausages and burgers), randomly collected from five regions of Tehran, Iran, was investigated by the aid of a gas chromatography-mass spectrometry (GC-MS), and the risk assessment was conducted. The concentration of 16 types of PAHs in sausage and burger samples was found in the range of 8.08 to 29.55 and 10.18 to 29.85 μg/kg, respectively. The concentrations of some PAHs such as anthracene (A) (14.12 μg/kg) and acenaphthylene (Acl) (13.4 μg/kg) were higher than the European Standard (2 μg/kg). Among the meat products with different meat percentages (50, 70, and 90), the highest level of total PAHs was noted in the product containing 90% meat (19.34 μg/kg), while the highest mean level of PAHs was noted in fried meat products (23.31 μg/kg). A positive and significant correlation between cooking method and brand of product with the concentration of PAHs (p-value  1E-4) risk levels, respectively. In this regard, further assessments to control and modify the cooking method among the Iranian population were recommended.This paper investigates whether the effect of female parliamentarians on environmental performance differs by the level of income. To that end, a threshold estimation approach is applied to a panel of 91 countries over the period 2002-2012. The results suggest the existence of income threshold effects in female parliamentarians-environmental performance nexus. Specifically, when it is above the income threshold value, the extent of this positive correlation is much greater than below it. It means that theoretically although the female parliamentarians have a higher awareness of environmental protection and a positive effect on environmental performance than men, the economic development of countries will affect the implementation of this effect. Countries tend to prioritize economic development when income levels are low, only in high-income countries will the proportion of female parliaments significantly improve the country's environmental performance. These results provide some important implications for policymakers when considering the relationship between female parliamentarians and environmental performance.A new class of robust superhydrophobic cotton fabric was prepared by chemically grafting method for removing oil from contaminated waters. Furthermore, the mechanical, chemical, and thermal durability of superhydrophobic cotton fabric was evaluated in detail. The superhydrophobic cotton fabric did not only showed excellent separation efficiency (ca.100%) and ultrafast separation rate (ca. 13,600 L/h m2) but also exhibited excellent durability. Especially, the oil/water separation rate was almost 10 times than that reported in previous works. The work provides a new method to design and large-scale prepare oil/water separation materials with high performance for industrial use.The aim of the presented study was to assess the relationship between air pollution expressed as particulate air matters less than 10 μm (PM10) and acute coronary syndromes (ACSs). In this observational study, we selected regions with low pollution according to PM10 (non-polluted) and with the highest pollution (polluted). The occurrence of percutaneous coronary interventions (PCIs) in patients with ACSs was matched according to the location. The current study included 7678 patients in polluted areas and 4327 patients from non-polluted regions. Analysing the period from January to December 2017, the number of patients undergoing angioplasty in monitored catheterization laboratories and the mean daily concentration of PM10 in all selected cities were calculated for each day. The annual average concentration of PM10 amounts to 50.95 μg/m3 in polluted and 26.62 μg/m3 in non-polluted cities (P  less then  0.01). The rise in PM10 pollution levels was related with the increased frequency of PCIs in patients with ACSs in polluted (P  less then  0.01) and non-polluted (P  less then  0.01) areas. In the non-polluted regions, the increase in PM10 concentration by every 1 μg/m3 causes 0.22 additional ACS angioplasties per week. In polluted regions, the same increase in PM10 concentration causes 0.18 additional ACS angioplasties per week. In non-winter weeks, the mean number of ACS PCIs expressed in promiles was lower than in winter weeks in polluted (P = 0.03) and non-polluted cities (P = 0.02). The study shows that the increase in air pollution expressed as PM10 concentration and winter time influences the frequency of ACS-related PCIs.In civil engineering, many geotechnical and forensic projects employ polyurethane (PU) for ground improvement, and the results have shown to be effective in terms of time and cost savings. However, similar to many other chemical stabilisers, the use of PU for soil stabilisation may have environmental repercussions. Therefore, this paper utilised a toxicity characteristic leaching procedure (TCLP) to investigate the potential for ground contamination resulting from the application of PU for the stabilisation of marine clay. Furthermore, the hazardousness of PU during the stabilisation of marine clay was investigated by testing its reactivity, ignitability, corrosivity and physical properties. The results reveal that the quantity of heavy metals present in PU is far below the regulatory limits. The results further confirm that PU is odourless and non-corrosive and that it is non-cyanide and non-sulphide-bearing. Selleckchem OTS964 However, PU is capable of igniting. Overall, the potential application of PU for ground improvement is promising due to its environmental friendliness.This paper examines the impact of board characteristics on environmental accounting information disclosure for listed mining companies in China. Board characteristics were categorized into board size, independence characteristics, diversity characteristics, behavioral characteristics, and incentive characteristics. The study further extended to analyze the impact of board characteristics on environmental disclosure before and after the promulgation of Environmental Information Disclosure Degree (EIDD). Using multiple regression analysis with a sample of 34 listed mining companies from both Shanghai and Shenzhen Stock Exchanges covering 2000-2018 period, we find a significant positive correlation between board size and Environmental Accounting Disclosure Index (EADI). Also, board independence measured by independent directors and the separation of the chief executive officer from board chairman revealed a positive and significant relationship with EADI. Similarly, behavioral characteristics measured by board meeting were positively correlated with EADI at 1% significant level.
