This paper elaborates the characteristics of scandium resource viewing from industrial chain. Recent discoveries of scandium deposit belong to laterite deposit, which is a vital type for future scandium resource and needs more attention from governments and mining companies. Constraints in blocking scandium rapid development lie in limited sources, insufficient supply leading to expensive prices. Scandium companies shall develop effective extracting scandium technology from laterite deposits, reduce production costs, which can ensure a steady supply of scandium. As it production capacity grows, the down-stream companies should develop the three pillar scandium industries in Al-Sc alloy, solid fuel battery and Sc-Na lamp, especially in the civil application of Al-Sc alloy and other applications. Economic profits shall be highlighted along with green, circular economy and boosting recycling scandium resource and environmental protection.

Air PM_2.5and PM₁₀ samples that were concurrently collected during March 5-14, 2008 were analyzed in their pollution level, daily changing trend, the ratios of PM_2.5/PM₁₀, and influent factors with results indicating that the daily average concentration of PM₁₀ was 220.0 μg/m³, 46.7% more than the second national standard (150 μg/m³), and that the daily average concentration of PM_2.5 was 132.5 μg/m³, 103.8% more than the US’s standard. This reveals a severe atmospheric particle pollution in this area. PM_2.5 which is more harmful to human is a major component of PM₁₀, about 63.6% on average. PM_2.5 and PM₁₀ concentration has a good correlation with humidity and wind velocity, increasing with the increasing of humidity and the temperature, and decreasing with the increasing of wind velocity. The meteorological conditions plays a key role in atmospheric particle pollution. This paper presents a reference to prevent air particulate pollution and to make policies.
