The estimation of the distribution of global anthropogenic heat release (AHR) from 1992 to 2009 was obtained by applying Defense Meteorological Satellite Program (DMSP)/Operational Linescan System (OLS) satellite data. The results indicate that global AHR was geographically concentrated, essentially correlating to economic activities. The anthropogenic heat flux concentrated in the economically developed areas, such as East Asia, Europe, and Eastern North America, reached a level high enough to influence regional climate. In contrast, the anthropogenic heat flux in vast areas, such as Africa, Central and North Asia, and South America, is very small. With the increases in global population and economic development, an increase in AHR was easily found. The model results show that AHR has a significant impact on surface temperature and that it is able to affect global atmospheric circulation, leading to a 1-2 K increase in the high-latitude areas of Eurasia and North America. The results show that AHR is able to affect global climate despite being limited to a region. Although the influence to global warming by AHR is not as large as greenhouse gases, such as carbon dioxide, on a global scale, AHR is an important factor in global climate change that should not be ignored.

The overuse of organophosphorus pesticides on cotton production is a big concern in China today. Therefore, developing methods for the rapid screening and confirming of pesticide residues in textiles has become a top public health security priority. Here, a method was established for the rapid screening and quantifying of 11 kinds of organophosphorus pesticides (ethoprophos, coumaphos, profenofos, diazinon, ethion, parathion, phosalone, quinalphos, dicrotophos, azinphos methyl, and tribuphos) in textiles by high-performance liquid chromatography high-resolution mass spectrometry (HPLC-HRMS). Rapid screening and quantifying could be completed by using software of Peakview and MultiQuant. Samples were extracted by the method of modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) and analyzed in the positive mode with MS detection. The results showed that the limits of detection were between 0.1 and 5.0 ng g−1, with correlation coefficients above 0.9990. The recoveries were in the range of 70.3 – 109.8%, with relative standard deviations from 5.1 to 16.4%. This method is accurate and simple, which can be used in the rapid screening and quantitative analysis of 11 kinds of organophosphorus pesticides in textiles.
