A total of 1800 3-year old seedlings of Norway spruce (Picea abies (L.)Karst.) from two Norwegian and one German provenance were treated with two different nitrogen levels during the 1992 growth season. The plants were kept during the following winter at two different temperature levels. In the spring of 1993 the nutrient application was resumed, and the plants were divided between three different treatments, 350 and 650 p.p.m. in open top chambers and a control plot outside the chambers. This treatment was repeated also during the following 1994 season.The growth and primary production was studied by photosynthesis experiments and by non-destructive growth measurements. The results indicate that raised winter temperatures may lead to increased needle loss and reduced growth the following season, particularly in northern provenances. Carbon dioxide significantly influenced growth in addition to nutrient level and winter temperature High CO2 also seemed to cause increased photosynthesis at early season, and earlier budbreak and growth cessation than in control plants.

An alkaline sample solution in combination with the complexing agent diethylenetriaminepentaacetic acid (DTPA) was employed to minimize interference from Ni and Co in the determination of As and Te by hydride generation inductively coupled plasma atomic emission spectrometry. Tetrahydroborate was also added to the sample solution, before the hydride was generated by acidification vith HCl in a continuous-flow system. The masking method was used for the determination of As and Te in the reference material NIST SRM 899 Nickel Ahoy. For the determination of As in a copper sample, the interference from Cu was removed by precipitation of the hydroxide and filtration. The precipitation method was used for the determination of As in the reference material NIST SRM 398 Unalloyed Copper V; hydride generation atomic absorption spectrometry was employed to determine the concentration of As.
