The evaporative emissions of anthropogenic volatile organic compounds (AVOCs) are sensitive to ambient temperature. This sensitivity forms an air pollution-meteorology connection that has not been assessed on a regional scale. We parametrized the temperature dependence AVOC fluxes in quality model and evaluated impacts surface ozone Beijing–Tianjin–Hebei (BTH) area China during summer 2017. dependency drove enhanced simulated ozone-temperature 1.0 1.8 μg m–3 K–1, comparable driven by...

Flow sensing exhibits significant potential for monitoring, controlling, and optimizing processes in industries, resource management, environmental protection. However, achieving wireless real-time omnidirectional of gas/liquid flow on a simple, self-contained device without external power support has remained formidable challenge. In this study, compact-sized, fully self-powered flowmeter (CSWF) is introduced with small size diameter down to less than 50 mm, which can transmit signals, as...

Formaldehyde (HCHO) plays a critical role in atmospheric photochemistry and public health. While existing studies have suggested that vehicular exhaust is an important source of HCHO, the operating condition-based diesel truck HCHO emission measurements remain severely limited due to temporal resolution accuracy measurement techniques. In this study, we characterized second-by-second emissions from 29 light-duty trucks (LDDTs) China over dynamometer real-world driving tests using portable...

Few studies have explored the relationship between benthic and planktonic assemblages in reservoirs, despite their role food chains maintaining ecological functions. Macroinvertebrates play a crucial webs contribute about 42% of whole-lake secondary productivity. Therefore, status is vital for good In this study, we selected Nanwan Reservoir, eutrophic thermally stratified reservoir China, to evaluate community macroinvertebrates different seasons explore relationships macroinvertebrate...
