Nitrous acid (HONO) plays an important role in the budget of hydroxyl radical (•OH) atmosphere. Vehicular emissions are a crucial primary source atmospheric HONO, yet remain poorly investigated, especially for diesel trucks. In this study, we developed novel portable online vehicular HONO exhaust measurement system featuring innovative dilution technique. Using coupled with chassis dynamometer, first time investigated emission characteristics 17 light-duty trucks (LDDTs) and 16 gasoline...
As a result of rapid urbanization, the road lengths and built-up areas in Zhengzhou are steadily expanding along with increasing fugitive dust emissions. Identifying physical chemical characteristics profiles is important achieving effective atmospheric pollution management. In this study, soil dust, (RD), building demolition cement (CE) were chosen as research objects. A total 94 samples collected from 20 sites. PM2.5 (particulate matter diameter ≤ 2.5 µm) PM10 10 obtained by using...
Heavy metals （HMs） pollution in agricultural soil-rice systems has attracted worldwide attention as it directly threatens regional ecological security and human health. To understand the heavy metal of agriculture soil rice high geological background areas, a total 200 paddy samples were collected southeast Chongqing. The concentrations arsenic （As）, cadmium （Cd）, chromium （Cr）, copper （Cu）, mercury （Hg）, nickel （Ni）, lead （Pb）, zinc （Zn） analyzed. comprehensive impact index （IICQ） was used...
<div class="section abstract"><div class="htmlview paragraph">Under the background of global dual carbon target, ammonia and hydrogen as carbon-free fuel, have become a research hotspot for internal combustion engines. The existing researches mainly focus on characteristics influenced by equivalence ratio, jet ignition so on, while relationship between emission should be also paid more attention. In this paper, impact characteristic parameters engine emissions is investigated...
A spectrophotometric method was developed to measure antioxidant free-radical scavenging capacity. Rhodamine B (RhB) oxidized by hydroxyl radical generated via the Fenton reaction yield a photoinactive RhB product. absorption at 550 nm restored when agents scavenged protect from oxidation. On basis of dose response recovery capacity, model calculate ability. This sensitive wide range activity with ascorbic acid reference set as one; capacity quercetin 635 compared 2 for benzoic acid.
Formaldehyde (HCHO) plays an important role in atmospheric photochemistry, HOx budget, and ozone formation. Several instruments have been developed for measuring ambient HCHO, yet few targeted primary emission sources due to their very high HCHO levels complex conditions. Here, we present a novel portable instrument, the Hantzsch-Abs, based on Hantzsch reaction absorption photometry, which is specifically designed online continuous measurement of concentrations both environment from vehicle...
To investigate the characteristics of elements in size-segregated atmospheric particulates, samples were collected using a 14-stage electrical low-pressure impactor (ELPI+) at an urban site Zhengzhou from October 1 till 25, 2016, and analyzed for 25 elements. Results show that crustal concentrated coarse particles toxic ultra-fine particles. The size distributions Na, Mg, Al, Si, Ca, Fe, Ti, S Cl uni-modal with dominant peaks range 1.43–2.14 µm or 0.295–0.487 µm. K, P, Mn Ba exhibited...
Anthropogenic activities may result in the accumulation of heavy metals soil, especially economic development zones with frequent industrial activities. Therefore, investigation and assessment soil metal pollution is one important measures for environmental management sustainable development. This study used Nemero evaluation, Kriging interpolation, cluster analysis, principal component analysis to investigate contamination degree, spatial distribution, origin Anhui Chaohu Economic...
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...
