Fourier transform infrared (FTIR) spectroscopy and checking electron microscope (SEM) analysis reveal the method of KPS affecting the composting process KPS stimulated the degradation of various organic substances such as lignin at high-temperature stage, therefore the degradation of lignin could speed up the production and decomposition of other elements; KPS made the dwelling regarding the product looser, with an increase of voids and skin pores, and more specific surface area associated with material, which was more desirable for microbial degradation activities. Therefore, the inclusion of KPS can market the decomposition of organic matter during the early phase of composting, accelerate the process of thermophilic stage, and shorten the composting process and enhance product maturity.The productivity of coal mines is seriously threatened by the combined disasters of fuel and coal natural combustion, which may have become a typical catastrophe mode. It is not clear how the gas and coal spontaneously combusted in the roof cutting along gob working face. The aim of this research would be to recognize the unique popular features of connected catastrophes in gob from two different types of roof cutting along working faces. In these two several types of roofing cutting along gob working faces, the paper constructs the permeability type of the gob. The results demonstrate that the data through the field test as well as the simulation outcomes agree, which validates the simulation’s reliability. In contrast to single sided roof cutting along gob working faces, double sided roof cutting along gob working faces demonstrably has a thinner oxidation area. Moreover, the oxidation zone of the dual part roof cutting along gob working faces is nearer to the working face, that is located in the low section of the gob 50 m behind the working face. The fuel surge location and also the coal spontaneous burning location tend to be divided because of the two fold side roofing cutting along gob working face, which reduces the possibility of Bioconcentration factor mixture disasters. Essential theoretical path for the avoidance and control over gob disasters into the roof cutting along gob working face is provided by the simulation outcomes.The open-pit mining location is highly afflicted with human being tasks, which aggravate soil erosion and interrupt surface ecology, bringing numerous issues and difficulties to its ecological administration and restoration, which has received extensive attention. The institution of an objective, timely and quantitative remote sensing monitoring, and analysis system when it comes to spatio-temporal evolution regarding the area ecological environment within the open-pit mining location is of good importance for the environmental security, management decisions, and lasting personal development. Based on the Google Earth Engine (GEE) system, this paper uses Landsat pictures to construct and calculate the remote sensing ecological list (RSEI) for the Pingshuo open-cast mine area (POMA) from 1990 to 2020 and monitor and evaluate its surface environmental environment. Combined with the Theil-Sen median, Mann-Kendall test, and Hurst index, the spatio-temporal procedure had been analyzed. The outcome showed that the ecological environmental high quality oea in the last three decades, which can be great for understanding its effect procedure on ecological quality and provides assistance for the handling of the region.In this research, 6229 brown rice grains from three major International Medicine rice-producing areas were gathered to research the spatial and variety distributions of heavy metals in rice grains in China. The potential sourced elements of hefty metals in rice grains were identified utilizing the Pearson correlation matrix and main component evaluation, additionally the health problems of nutritional exposure to hefty metals via rice consumption had been considered utilising the threat index (Hello) and complete carcinogenic danger (TCR) strategy, correspondingly. Moreover, 48 paired soil and rice examples from 11 urban centers were collected to create a predicting model for Cd accumulation in rice grains utilising the multiple linear stepwise regression analysis. The outcomes suggested that Cd and Ni had been the main heavy metal and rock toxins in rice grains in China, with approximately 10% of samples exceeding their corresponding maximum allowable restrictions. The Yangtze River basin had thicker air pollution of hefty metals compared to Southeast Coastal area and Northeast Plain, and the PF-9366 order indica rice varieties had greater heavy metal accumulation capabilities compared with the japonica rice. The Cu, Pb, and Cd primarily originated from anthropogenic sources, while As, Hg, Cr, and Ni originated from both normal and anthropogenic sources. The mean HI and TCR values of dietary contact with hefty metals via rice consumption ranged from 2.92 to 4.31 and 9.74 × 10-3 to 1.44 × 10-2, correspondingly, much higher compared to acceptable range, so that as and Ni were the main contributor into the HI and TCR for Chinese adults and children, correspondingly. The available Si (ASi), total Cd (TCd), available Mo (AMo), and available S (AS) were the primary soil aspects identifying grain Cd buildup. A multiple linear stepwise regression model was built centered on ASi, TCd, AMo, and also as in grounds with good precision and accuracy, which could be used to anticipate Cd accumulation in rice grains and guide safe rice production in contaminated paddy fields.Pollution by anthropogenic litter is an important risk to global ecosystems. Seabirds are frequently made use of as ecological screens of litter intake, but similar research is unusual for terrestrial wild birds.
