    Notes: Abstract The association between alcohol consumption and cancer of the colon and rectum was investigated in a prospective cohort study, conducted in the Netherlands from 1986 onwards among 120,852 men and women, aged 55 to 69 years. During 3.3 years of follow-up, 312 and 166 cases of colon and rectal cancer had accumulated, respectively. After exclusion of cases diagnosed in the first year of follow-up the analysis was based on 217 incident cases of colon cancer (107 men and 110 women) and 113 cases of rectal cancer (75 men and 38 women). For colon cancer, no association with total intake of alcohol nor with the consumption of beer and wine, specifically, could be demonstrated; for liquor intake, a significant (P=0.04) decreasing risk with increasing consumption was observed. For rectal cancer in men, positive trends were observed for total alcohol intake (P=0.04), beer (P=0.05), and liquor (P=0.06). Results for rectal cancer in women were consistent with those in men, but data were too sparse to provide stable estimates. Simultaneous adjustment for beverage type and quantity appeared to strengthen the association of rectal cancer with drinking beer (relative rate (yes/no)=2.0, 95 percent confidence interval=1.1–3.9), although, a dose-response effect was not observed. When alcohol intake from beer, wine, and liquor were included as continuous variables, the association was somewhat stronger for liquor than for beer, but none of the associations were statistically significant. It is concluded that consumption of alcoholic beverages (beer, in particular) is associated with an increased risk for rectal but not colon cancer.

    Notes: Abstract During the cruise ANT VII/1 (September/October 1988) of the German research vessel Polarstern the latitudinal distributions of several nonmethane hydrocarbons were measured over the Atlantic between 45°N and 30°S by in-situ gas chromatography. On the average, the highest mixing ratios of ethane, propane, i- and n-butane, ethene and acetylene were observed in the Northern Hemisphere around 40° N and just north of the intertropical convergence zone, respectively. South of the equator, a bulge in the mixing ratios of ethane and acetylene was observed indicating aged biomass burning emissions. This observation coincided with enhanced tropospheric ozone found in this region at this season. On the average ethane and acetylene mixing ratios were around 500 and 100 ppt, respectively, whereas the levels of the other NMHC were in the range of some ppt up to 100 ppt. compared with the results of the cruise ANT V/5 (March/April, 1987), the ethane mixing ratios in September/October proved to be a factor of 3 lower in the Northern Hemisphere and a factor of 2 higher in the Southern Hemisphere, probably due to seasonal effects. Possible causes are the higher OH radical concentrations in summer, which result in a faster removal of ethane or stronger emission from biomass burning which also peaks in the dry season. The relative pattern of the hydrocarbons just north of the ITCZ was very similar for both measurement series. In this region, the NMHC were advected by long-range transport from the continent, whereas generally the ocean itself acts as a major NMHC source. This is supported by the results of a balance calculation between oceanic emissions and atmospheric removal rates.

    Notes: Abstract The atmospheric concentration of peroxyacetylnitrate (PAN) was measured during a cruise of the R.S. Polarstern from Bremerhaven (Germany) to Rio Grande do Sul (Brazil) in September/ October 1988. The measurements were made in-situ by a combination of electron capture gaschromatography with a cryogenic preconcentration step. The theoretical lower limit of detection (3σ) was 0.4 ppt. The mixing ratios of PAN varied by more than three orders of magnitude from 2000 ppt in the English Channel to less than 0.4 ppt south of the Azores (38° N). South of 35° N, PAN levels were below the detection limit, except at 30–31° S off the eastern coast of South America. Here, PAN mixing ratios of 10 to 100 ppt were detected in continentally influenced air masses. Detectable levels of PAN were mostly observed in air masses of continental or high northern origin. Changes in the wind directions were usually associated with substantial changes in the PAN mixing ratios.
