The selection of proper refrigerants for natural gas liquefaction processes play a key role in cycle?s efficiency. Mixed have been proven to improve exergy efficiency over single pure refrigerant. However, the future some these with higher global warming potential index are unknown due continuous restriction being enforced by energy and environmental agencies past few decades. This study examin...

A photoelectrochemical sensor has been developed for the detection of polycyclic aromatic hydrocarbon pollutant benzo [a]pyrene (BaP). An n-butyl lithium intercalation stripping method is applied to prepare tungsten disulphide nanosheets (WS2 NSs). WS2 NSs and ?-cyclodextrin (?-CD)-modified MoS2 quantum dots (QDs) are then compounded by hydrogen bonding between amino hydroxyl groups. After asse...

Petroleum hydrocarbon is the main source of energy in the world, as well as the main pollutant of soil and water. Accidental spills, uncontrolled landfills or improper storage and leaking underground storage tanks can all lead to contamination1. Compared with physicochemical methods, bioremediation has gained increasing interest in dealing with petroleum hydrocarbons, as it is environmentally f...

BACKGROUND Microorganisms have devised ways by which they increase the bioavailability of many water immiscible substrates whose degradation rates are limited by their low water solubility. Hexadecane is one such water immiscible hydrocarbon substrate which forms an important constituent of oil. One major mechanism employed by hydrocarbon degrading organisms to utilize such substrates is the pr...

Lipid disorder has been demonstrated to be a key biomarker for many chronic diseases, and PM 2.5 is emerging as risk factor altered lipid profiles. However, few studies have focused on changes in comprehensive indices caused by -bound polycyclic aromatic hydrocarbon (PAH) exposure the older adult population. The aim of this study was investigate relationship between multiple categories PAHs Thi...

 The effectiveness of hydrocarbon bioremediation strategies approaches is depending on various issues such as type and volume of pollution, nutrient accessibility in the target ecosystem, time, biodiversity of microorganisms, pollutant bioavailability and many others. In the present research, laboratory studies were carried out on the bioremediation of coastal sediment samples ...

BACKGROUND Environmental pollutants are thought to be one of major triggers of atopic dermatitis (AD). OBJECTIVE We attempted to evaluate the clinical effects of environment with low indoor pollutant levels on AD management. METHODS Fifty-one children (mean age 1.7 years) with moderate to severe AD who failed to show improvement with conventional management were recruited. Disease severity ...

Unborn children are exposed to environmental pollutants via the placenta, and there is a causal relationship between maternal intake of pollutants and fetal exposure. Placental examination is an effective way for acquiring data for estimating fetal exposure. We analyzed the concentrations of 104 congeners of persistent organic pollutants, seven organotin compounds, five heavy metals, and methyl...

The purpose of this paper is to analyse and compare the values of a marginal change in the area of land as a pollutant sink under different decision-making contexts and objectives: international coordination versus national policies for pollutant reduction, and maximization of net benefits versus minimization of costs for pollutant reductions. The analytical results show that a coordinated poli...
