The objective of this study was to evaluate supplemental organic chromium（Cr） to finishing lambs on growth performance, carcass characteristics, and meat quality. eighteen suffolk lambs（age（4.5±0.2） mon;（25.8±3.6） kg body weight（BW）） were randomly assigned to three levels of supplemental organic Cr（0.0, 0.2 and 0.4 mg kg^–1 dry matter（DM）） in a complete random design. Growth performance was evaluated for 70 d, and then lambs were slaughtered to study carcass characteristics and chemical composition of meat. Orthogonal contrasts were performed（contrast one-average level 0.2 ppm Cr vs. average level 0.4 ppm Cr; contrast two-level 0 vs. average levels（0.2＋0.4） ppm Cr）. Orthogonal polynomials were used to estimate the linear and quadratic effects of Cr concentrations. Growth and carcass performance were not affected by supplemental organic Cr. Muscle conformation and leg perimeter linearly increased（P〈0.05） as organic Cr level increased in the diet. Kidney fat decreased linearly（P〈0.05） as supplemental Cr increased. In Longissimus dorsi（LD）, the ash content decreased linearly, and shear force（kg cm^–2） increased（P〈0.05） as organic Cr level increased in the diet. It is concluded that organic Cr did not affect growth performance, but it improved positively the muscle conformation, reduced kidney fat, whereas in LD there was an increment in shear force in finishing carcass lambs.

During the winter period（January–March 2016）, the total suspended particles（TSP） and particulate matter smaller than 2.5 μm（PM2.5） were character.zed by the application of various analytical techniques in four.zones of the Metropolitan Area of Monterrey in Mexico. To evaluate the seasonal variation of some elements in the particulate matter, the results of this study were compared with those obtained during the summer season（July–September 2015）. The speciation of the C_（1s） signal by X-ray photoelectron spectroscopy revealed the contribution of aromatic and aliphatic hydrocarbons as the main components in both seasons. Conversely, carboxylic groups associated with biogenic emissions were detected only in winter. The percentages of SO_4^（2-） ions were lower in winter, possibly caused by the decrease in the solar radiation, and relative humidity recorded. The results of the ICP analysis revealed that Fe, zn and Cu were the most abundant metals in both TSP and PM2.5 in the two seasons. There were significant seasonal variations for concentrations of As, Ni and zn in the urban area and for Fe, As, Cd, Ni and zn in the industrial zone. This was attributed to the greater burning of fuels as well as to an increase in vehicular traffic, the effect of thermal inversion and changes in some meteorological parameters. The results of the sequential microanalysis by raman spectroscopy and SeM/eDS allowed observation of deposits of carbonaceous material on the particles and to perform the speciation of particles rich in Fe and Pb, which helped infer their possible emission sources.
