Hourly concentrations of non-methane hydrocarbons (NMHCs) recorded between June and August 2006, at two monitoring sites (Gijang and Jin) in Busan were analyzed to examine the characteristics and photochemical reactivity of NMHC sources. The two sites represent urban (Jin) and suburban (Gijang) Busan, which is a typical Korean city. Positive matrix factorization (PMF), applied to identify and apportion the sources of NMHCs, revealed nine sources for Gijang and ten sources for Jin. To explore the contribution of each NMHC source to ozone formation at the two sampling sites, the ozone formation potential was estimated for each source. The largest contributors to ozone formation were sources characterized by 1,2,3-trimethylbenzene (26.4%) at Gijang and by toluene, ethylbenzene, and xylenes (22.5%) at Jin, which were composed mostly of heavy hydrocarbons and aromatics. Secondary sources included two coating sources (20.9%, 12.2%) and vehicle exhaust (10.3%) at Gijang and a source represented by toluene (17.4%), vehicle exhaust (15.9%), and a coating-2 source (9.6%) at Jin. Conditional probability function (CPF) and potential source contribution function (PSCF) analysis methods were used to identify the directions of local sources and to locate potential source regions, respectively. The CPF and PSCF results agreed well for the majority of sources resolved by PMF and thus were very useful in identifying the major sources contributing to ozone formation at the two study sites.  相似文献

Semen parameters and testicular dimensions in small breed dogs below ten‐kilogram bodyweight     

Romy Zeller  Andrea Meyer‐Lindenberg  Beate Walter  Christian Leykam  Ulrike Flock  Sven Reese  Christiane Otzdorff 《Reproduction in domestic animals》2019,54(9):1244-1250

Because of few available data on semen parameters in small breed dogs, the study aimed to analyse semen and measure testes of dogs ≤10.0 kg bodyweight. Semen was collected from 41 fertile stud dogs, which were divided based on bodyweight: group 1 ≤ 5.0 kg and group 2 between 5.1 and 10.0 kg. Median values for ejaculate volume (group 1: 1.2 ml; group 2: 2.2 ml), total sperm output (group 1: 110.7 × 10⁶; group 2: 215.1 × 10⁶) and testicular volume (group 1: left testicle 2.8 ml, right testicle 2.7 ml; group 2: left testicle 5.5 ml, right testicle 5.0 ml) were lower in group 1 compared to dogs of group 2 (p = .001; p = .001; both testes: p < .001). There was no difference in sperm concentration (p = .985). Based on these results, introduction of an additional weight group to the commonly used reference values is recommended, since values for ejaculate volume, total sperm output and testicular dimensions for dogs ≤5.0 kg bodyweight differed significantly from values of dogs with a bodyweight from 5.1 to 10.0 kg.  相似文献

Studies on contamination of beef with tissues of the central nervous system (CNS) as pertaining to slaughtering technology and human BSE-exposure risk     

Lücker E  Schlottermüller B  Martin A 《Berliner und Münchener tier?rztliche Wochenschrift》2002,115(3-4):118-121

Contamination of beef by tissues of the central nervous system (CNS) due to slaughter technology causes some concern considering the potential health hazard by food borne exposure to the infectious agent of BSE. The present study was designed to quantify the extent of CNS contamination as pertaining to stunning and splitting technology. Of the 726 animals 48 contained a total of 58 emboli-like particles in lungs and/or right ventricles. The incidence of emboli-like particles was found to be slightly higher in animals slaughtered without pithing (5.9%) than in the animals slaughtered with pithing (4.1%). Of the 58 emboli-like particles only two were positive in the anti-NSE western immunoblotting (0.3% of the 726 animals). The immuno reaction of these NSE-positive particles was several orders of magnitude lower as obtained by pure brain material. The microscopical analysis of the two NSE-positive emboli-like particles for presence of CNS-like tissues was negative. Following splitting of carcasses by sawing with and without prior removing the spinal cord we found NSE-positive reactions in 32% and 17% of the samples, respectively. The immuno reaction, however, was predominantly comparable to standard material containing less than 0.5% CNS. Overall the results show that CNS contamination of bovine carcasses cannot be excluded by current slaughter technology. However, the additional human BSE-exposure risk can be judged to be at least minor when considering extent of contamination, dilution effects and BSE-testing.  相似文献

Bioactive compounds in cod (Gadus morhua) products and suitability of 1H NMR metabolite profiling for classification of the products using multivariate data analyses

This work investigates the suitability of (1)H NMR spectroscopy to identify the fate of some bioactive compounds in seafood submitted to several processing conditions and examines the possibility of using (1)H NMR spectroscopy profiling to classify such products. Perchloric acid extracts of cod white muscle from newly killed and (i) unprocessed, (ii) boiled, and (iii) fried fillets and from (iv) frozen fillets, (v) the frozen fillets after thawing, and (vi) their drip loss and from (vii) rehydrated cod klippfish (n = 5) were analyzed by 500 MHz (1)H NMR spectroscopy. It was possible to identify taurine, betaine, anserine, creatine, and trimethylamine oxide (TMAO) in all extracts examined, and frozen fish was recognizable by the presence of dimethylamine (DMA). None of the heating procedures seemed to induce the loss of bioactive compounds from the fillet, but freezing and thawing did: the compounds were lost in what is known as drip loss. About 80% of the samples were correctly classified using a probabilistic neural network procedure having as inputs the scores of the first 20 principal components of the principal component analysis of a selected region of the NMR spectra.  相似文献
