Polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/F) emissions in fly ash from multiple-field electrostatic precipitators different sized sintering plants were studied. The monochlorinated-trichlorinated tetrachlorinated-octachlorinated PCDD/F concentrations higher for small (90 m2) than medium (91-180 large (>180 plants. less-chlorinated contributions to the total increased as particle size decreased moving through precipitator stages; abundance of congeners homologues also increased....
The influence of desulfurization systems in sintering plants on polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/F) concentrations, profiles, emission factors was studied. Mono- to tri-CDD/Fs tetra- octa-CDD/F concentrations were 4.4 ± 2.3 10.5 8.3 ng m(-3), respectively, at the inlets 0.87 0.48 0.47 0.22 after desulfurization. toxic equivalents (TEQs) 0.95 0.093 0.51 0.040 I-TEQ m(-3) desulfurization, respectively. congener profiles homologue distributions dominated by 2-MoCDF MoCDF,...
The concentrations and formation pathways of mono- to octa-chlorinated dibenzo-p-dioxins (PCDDs) dibenzofurans (PCDFs) were investigated in main organochemical industries. High levels PCDDs PCDFs detected. total 27 PCDD/F congeners chloranil, 2,4-D, 1,4-dichlorobenzene 5302397 ± 8944449, 20963 15908, 242 67 pg g(-1), respectively, the less-chlorinated 12006 20155, 9536 5594, 195 94 respectively. distribution trends less more chlorinated PCDD/Fs similar different chemical plants because their...
Gas-particle partitioning of polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/Fs), and biphenyls (PCBs) was evaluated in flue gases emitted from two municipal solid waste incinerators. Total PCDD/Fs dl-PCBs the gas were presented, decreasing order, within phases, particulate aqueous phases. PCDD/F concentrations ranged 0.75 to 15 ng m–3, while phase they 0.14 8.1 m–3. Dioxin-like (dl-) PCBs had 0.18–28 m–3 gas, 0.041–1.3 phase. dl-PCB levels associated with specific size ranges...
Atmospheric particle matters which contribute the most to haze weather in China have raised public awareness recent years. This paper collected current research status of PM2.5 and hourly data were recorded from authoritative websites shows outdoor concentration PM10 July 2015 December Tangshan urban area. The indoor by dust monitor compared with counterparts analyze variation factors PM2.5. results indicate close correlation between district paper.
Abstract The sintering flue gas samples were collected at the inlets and outlets of desulfurization systems to evaluate influence on PCNs emission concentrations, profiles, factors. concentrations 27888–153672 pg m −3 11988–42245 ,respectively. Desulfurization showed excellent removal for PCNs, efficiencies increase with increasing chlorination level. Lower chlorinated homologs are more sensitive process than higher ones. High levels also detected in gypsum (11600–29720 g −1 ) fly ash...
For most people, majority of their lives are spent in an indoor environment. With the improvement living, air pollution is impacting human health. In this paper, through analysis sources and adverse health effects several common pollutants, pollutants major contributing factors to chronic diseases mortality. It should be treated urgently with people's standard living improvement. Finally, it mentioned that some methods by controlling source, improving ventilation systems exhaust contaminated...
The molecular phylogeny of the Pinaceae represented by 13 species 10 genera was constructed from PCR-RFLP analysis chloroplast gene trn K, which approximately 2557 bp long. Ninety-two restriction sites, 68 were variable, identified 16 enzymes. Thirty-five polymorphic sites phylogenetically informative. site data analyzed PAUP (version 3.1.1) with both Wagner parsimony method and Dollo method. As a result, parsimonious trees have similar topologies except for position Cedrus....
Excessive environmental regulation can achieve improvement, but it is not conducive to sustainable improvement. This paper takes the "one-size-fits-all" (OFA) in process of China's central protection inspection (CEPI) as an example explore occurrence mechanism from perspective multiple co-governance. Using fuzzy set qualitative comparative analysis (fsQCA), we find that four distinct mechanisms result OFA. Based on mechanisms, even if pollution behavior enterprises serious, local governments...
The Chinese mitten crab (Eriocheir sinensis) holds significant importance as a popular aquaculture food source; however, there are concerns about its potential contamination with polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), biphenyls (PCBs) from both aquatic environment. To assess the associated health risks identify sources of in crabs, comprehensive investigation was conducted, including total 70 samples web. results demonstrated that crabs predominantly exhibited...
