Surface sediments in the Baltic Sea contained manganese at mean concentrations of 3550–8960 mg/kg dry weight; the high manganese concentrations were thought to be due to ferro - manganese concretions and riverine loads. (...) Concentrations of manganese in terrestrial plants tend to range from 20 to 500 mg/kg. (...) There are numerous reports of foliar manganese levels in excess of 2000–4000 mg/kg. Mean manganese concentrations in birds’ eggs from a variety of geographical areas range from 1 to 5 mg/kg dry weight, mean liver concentrations range from 3 to 11 mg/kg dry weight, and mean feather concentrations range from 0.3 to 40 mg/kg dry weight.

Concentrations ranged from below the limit of detection to 0.94 µg/l, with a mean concentration of 0.21 µg/l. 2-Butoxyethanol was detected in 56% of the 50 beverage samples (detection limit 6.80 µg/l). Concentrations ranged up to 73.8 µg/l, and the mean concentration was 6.46 µg/l (Conor Pacific, 1998). (...) The ChemCAN4 model estimates average concentrations throughout the region; therefore, actual concentrations in the vicinity of releases could be higher than those estimated by the model.

Methods Oxygen cylinders and concentrators were compared in terms of functionality and cost. (...) Cylinder costs are greatly influenced by leakage, which is common, whereas concentrator costs are affected by the cost of power far more than by capital costs. Only two of 12 facilities in the Gambia were found suitable for concentrators; at the remaining 10 facilities, cylinders were the better option.

Editorial: ECLAC August 1998 Download Publication pdf Description Abstract Concentration in liner shipping means that relatively larger shipping companies are increasing their market share at the expense of the remaining smaller players. (...) Another cause of the process of concentration is technological change, which has led to an increase of fixed costs as a proportion of total average costs. (...) The document presents a generally positive picture. The word concentration might initially raise the issues of abuse of market power and monopoly rents, but importers, exporters, consumers, ports, and major east-west carriers are all likely to gain from the described process.

Noting that the nvPM mass concentration measurement performed with the new much more sensitive measurement method could be related to the smoke number standard to control non- visibility of exhaust plumes, the CAEP/10 standard was introduced with a maximum nvPM mass concentration limit. This maximum nvPM mass concentration was developed based on a statistical relationship between nvPM mass concentration and the smoke number (SN). (...) A graphical The Landing and Take-Off Particulate Matter Standards for Aircraft Gas Turbine Engines CHAPTER THREE Local Air Quality 102 representation of the CAEP/10 nvPM mass concentration standard is shown in Figure 22. The CAEP/10 nvPM mass concentration standard and associated reporting were included in the ICAO Annex 16, Volume II, Amendment 9.
