Analysis of China’s New Energy Industry Development from the Perspective of Low-Carbon Economy

At present, the world is experiencing a serious climate change problem, and the consumption of high-carbon energy sources such as coal and oil undoubtedly brings great harm to the environment. In this context, some European and American countries have promoted a low-carbon revolution with high energy, high efficiency and low carbon emissions, focusing on developing low-carbon technologies. This paper mainly discusses the new energy industry from the perspective of low-carbon economy in China, and believes that China should also make a deep thinking on low-carbon economy and makes improvements of the industrial energy of some enterprises. This paper hopes to offer some references for the development of small and medium enterprises

Association between urinary polycyclic aromatic hydrocarbons and unexplained recurrent spontaneous abortion from a case-control study

Polycyclic aromatic hydrocarbons (PAHs) have been reported to be associated with adverse pregnancy outcomes. However, there is limited knowledge regarding the effects of single or mixed PAHs exposure on unexplained recurrent spontaneous abortion (URSA). This study aimed to investigate the association between monohydroxylated polycyclic aromatic hydrocarbons (OH-PAHs) and URSA in a case-control study. The results showed that 1-NAP, 2-NAP, 9-FLU, and 1-PYR were detected in 100% of the subjects among measured all sixteen OH-PAHs. Compared with those in the lowest quartiles, participants in the highest quartiles of 3-BAA were associated with a higher risk of URSA (OR (95%CI) = 3.56(1.28–9.85)). With each one-unit increase of ln-transformed 3-BAA, the odds of URSA increased by 41% (OR (95%CI) = 1.41(1.05–1.89)). Other OH-PAHs showed negative or non-significant associations with URSA. Weighted quantile sum (WQS) regression, Bayesian kernel machine regression (BKMR), and quantile-based g-computation (qgcomp) analyses consistently identified 3-BAA as the major contributor to the mixture effect of OH-PAHs on URSA. Our findings suggest that exposure to 3-BAA may be a potential risk factor for URSA. However, further prospective studies are needed to validate our findings in the future
