Emissions of di-(2-ethylhexyl) phthalate (DEHP) from one type polyvinylchloride (PVC) flooring with approximately 13% (w/w) DEHP as plasticizer were measured in the Field and Laboratory Emission Cell (FLEC). The gas-phase concentrations versus time at air flow rate 450 mL·min(-1) five different temperatures: 23 °C, 35 47 55 61 °C. experiments terminated two weeks to three months after steady-state was reached interior surface FLECs rinsed methanol determine concentration DEHP. most important...
The emission of di-2-ethylhexyl phthalate (DEHP) from vinyl flooring (VF) was measured in specially designed stainless steel chambers. In duplicate chamber studies, the gas-phase concentration increased slowly and reached a steady state level 0.8-0.9 μg/m(3) after about 20 days. By increasing area decreasing that surface within chamber, time to reach significantly reduced, compared previous study (1 month versus 5 months). adsorption isotherm DEHP on surfaces explicitly using solvent...
Phthalates are widely used as plasticizers, and improved ability to predict emissions of phthalates is interest because concern about their health effects. An experimental chamber was measure di-2-ethylhexyl-phthalate (DEHP) from vinyl flooring, with ammonium sulfate particles introduced examine influence on the emission rate partitioning DEHP onto airborne particles. When were at concentrations 100 245 μg/m3, total (gas + particle) increased by a factor 3 8; under these conditions,...
There are significant co-benefits to reducing black carbon emissions for air quality, human health and the climate; yet pollutant has not received sufficient policy attention in China. Overall, realizing is complicated by fact that climate quality goals have been pursued separately from each other. In this article, we explore current legal status of across domains pollution prevention control, change with a view identify synergies opportunities an integrated approach. We suggest three ways...
Horizontal well fracturing is a pivotal technology for enhancing the efficiency of shale oil and gas development. Shale reservoirs exhibit significant heterogeneity intricate fracture propagation patterns, often resulting in uneven multiple fractures caused by horizontal fracturing. Temporary plugging plays critical role optimizing patterns; however, there currently limited research on its optimization. Based hydraulic simulation, an optimization study was conducted temporary reservoirs....
The developing countries rely heavily on imports of capital goods to spur economic growth. When the economy grows, energy consumption rises, adversely impacting climate change. low levels renewable share in total consumption, nations confront a difficult task achieving SDGs targets related an increase and access affordable, reliable, modern energy. Finding solutions usage is critical. International trade unavoidable part development, prompting us consider impact usage. This study explores...
Air pollution has become an increasingly serious environmental problem in China. Especially winter, the air northern China becomes even worse due to winter heating. The “coal gas” policy, which uses natural gas replace coal heating system was implemented Beijing year 2013. However, effects of this policy reform have not been examined. Using a panel dataset 16 districts Beijing, paper employs first difference model examine impact on quality. Strong evidence shows that significantly improved...
Chamber tests are usually used to determine the source characteristics of semi-volatile organic compounds (SVOCs) which critical quantify indoor exposure SVOCs. In contrast volatile (VOCs), sorption effect SVOCs chamber surfaces needs be considered due much higher surface/air partition coefficients, resulting in a long time reach steady state, frequently on order months, and complicating mathematical analysis data. A test is also complicated if material-phase concentration not constant. This...
Indicators based on the developed version of Capability Maturity Model were set up to access maturity degree China's seven pilot carbon markets from 2013 2017. Results show that Shenzhen and Beijing ranks first; while those Guangdong, Hubei, Shanghai rank second. Tianjin Chongqing lowest. Most failed perform well price efficiency except Shenzhen. There is significant disparity in scores got, with a range 9 73. The drivers maintain market different among markets, either good performance...
Incorrect indicators and starting years for emission cumulation can lead to confusion regarding the concepts of climate equity responsibility. This article examines variations in results obtained by using different calculate responsibilities among country parties groups UNFCCC. The utilizes historical greenhouse gas (GHG) emissions data from 193 countries spanning period 1850 2021. is aggregated various sources including EDGAR, Climate Watch, Global Carbon Budget (GCB). calculates cumulative...
In this study, the characteristics, probable source, and potential carcinogenic risk of 16 polycyclic aromatic hydrocarbons (PAHs) in surface water Liaohe River were investigated. Twelve sampling points selected, samples collected both dry flood periods 2011. Sample analysis indicated that concentration total PAHs varied from 840.50 ng/L to 4274.73 period, 387.76 1997.83 period. The representative period benz[a]anthracene (Baa), naphthalene (Nap), chrysene (Chr), whereas Phenanthrene (Phe),...
Human society is facing great challenges to address global climate change. How move the international process forward still a serious problem for politicians. Geoengineering's, so called Plan B cope with change has attracted attentions of community lot debate on its impact, risks from an ethical view as well governance at level. In this paper, we focus some important issues geoengineering including definition, characteristics, ethics and governance, etc. then put suggestions China's considerations.
The Low-carbon City Pilot (LCCP) policy is a new environmental governance model to achieve carbon neutrality, promote low-carbon pilot city development, and address climate change. Taking LCCP as an exogenous shock, this paper examines the impact of on urban green technology innovation its transmission mechanism from 2005 2017. Based Difference-in-Difference (DID) method, following results are obtained: can innovation, remain robust through series robustness tests. Mechanism analysis shows...
Abstract The coalbed methane (CBM) productivity is directly determined by the fracture permeability during hydraulic fracturing, which regulated distribution of proppants. proppant may be unevenly distributed in because variables like architecture and characteristics sand‐carrying fluid. This study used two types random functions to produce different ununiform distributions clusters large‐scale fractures, with aim investigating effect these on overall fracture. A model fluid‐structure...

In response to environmental regulatory pressure from the government, enterprises – as main employers of labor adjust their production-related choices and may alter demand for labor. Numerous researches have probed into how regulations affect demand, which has emerged a significant concern in discourse around adoption regulation policies. Nonetheless, many predominantly concentrates on evaluation effects economic levels. Moreover, rare attention been paid social activities, especially terms...
Summary COVID-19 is caused by the SARS-CoV-2 coronavirus and was first reported in central China December 2019. Extensive molecular surveillance Guangdong, China’s most populous province, during early 2020 resulted 1,388 RNA positive cases from 1.6 million tests. In order to understand epidemiology genetic diversity of we generated 53 genomes infected individuals Guangdong using a combination metagenomic sequencing tiling amplicon approaches. Combined epidemiological phylogenetic analyses...
