Although they use modern equipment, such as wet suit, face mask, mouth piece with demand valve, spear gun, weight belt, and fins, their lack of knowledge of diving medicine is apparent. On the average, 180 cases of decompression sickness (DCS) per year were reported to occur in the Pescadores. We conducted studies in 1990 and 1992 on three islands of the Archipelago. At the time of our study, an estimated 140 diving fishermen resided on these three islands. Of the 62 fishermen interviewed, 14 volunteered for the recording of dive profiles using a diver-carried data logger. In the summer of 1990, a group of eight fishermen dived, on the average, to a depth of 17.8 +/- 5.3 m (mean +/- SD; range, 8-27 m) for 26.9 +/- 19.7 min (5-66 min). Although the diving depth was similar to that of the average recollections of 43 divers, 20.1 +/- 4.4 m (15-30 m), the actual diving time was far shorter than that of their recollections, 426 +/- 138 min (240-630 min). The post-typhoon sea floor conditions may have shortened their diving time. In the summer of 1992, a group of six fishermen dived to 20.5 +/- 3.8 m (15-26 m) for 56.4 +/- 21.2 min (18-84 min). Again, the diving depth matched that of their recollection well, 22.2 +/- 2.5 m (20-26 m), but their bottom time was far shorter than they believed, 270 +/- 108 min (120-480 min). They used no decompression procedures, regardless of the bottom time and diving depth. In the 1990 group, 5 out of 10 equivalent single dive bottom times (ESDBT) exceeded U.S. Navy no-decompression (No-D) air dive limits; whereas in the 1992 group, 7 out of 9 ESDBTs exceeded No-D limits. Eight of the 38 discrete dives exceeded the No-D limits, even if we underestimate their decompression stress by disregarding their repetitive dive history. However, no symptoms of DCS were observed in either the 1990 or 1992 groups of 14 divers, despite 63% of the ESDBTs and 21% of discrete dives having exceeded the No-D limits. Adaptation to diving work may have allowed them to exceed the established No-D limits. The existing records of incidence of DCS from this region suggest that previously they must have dived longer or deeper or both during times of abundant resources.

The origin of long-distance water supply in the central German area and its significance from a hygienic viewpoint	1994	Malyska, G., Landeshygieneinstitut Halle.	Read more...

Pub Date Free Form / Volume 196 Issue 1 Start Page 1 Other Pages 22 Notes Place of Publication ISSN/ISBN 0934-8859 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract By means of the climatic, hydrological and hydrogeological conditions in the middle German area the unfavorable water household also due to anthropogenic influences caused through mining and industry will be described. These conditions have, already in the first half of this century, lead to disadvantages concerning the drinking water supply for the population in this territory. Based on older ideas for improving the water supply in the middle German area the long-distance water supply system Elbaue-Ostharz was built after the 2. world war using the water supplies of the river Bode in the Harz, of the Elbaue as well as water from the DÃ¼bener Heide to overcome the bad water supply situation in middle Germany. In this connection the efforts of the public health service for improving the drinking water quality in the former country of Sachsen-Anhalt in the DDR will be described. Due to an increased connection of the population in the middle German area with local central water supplies as well as with the long-distance water supply up to 1990 92% of the population could be supplied with drinking water from central water supplies. Nevertheless it was not possible to manage all problems of drinking water quality up to 1990. These problems concerned local central water supplies due to not existing or inadequate plants for water refinement in waterworks and poor conditions of the drinking water pipe nets. Despite all an increasing improvement of the drinking water could be registered as a result of decrease in drinking water consumption, the shutting of water works with water catchments on hygienic unfavorable places, the refurbishment of water works and the further connection from communes with long-distance water supplies. At present and in future too the long-distance water supply will be necessary for the middle German area to guarantee a sufficient quantity as well as quality of drinking water for the population in this territory.

Measurements of plaque, calculus, bleeding, probing depth and clinical attachment level were made at 4 proximal sites per tooth. Results were compared to those for 132 regular attenders. The irregular attenders had more sites with plaque (46.3 +/- 27% versus 17.3 +/- 21.1%) than the regulars and significantly more sites which bled (53.7 +/- 20.4% versus 33.6 +/- 20.7%) and with calculus (35 +/- 21.1% versus 13.4 +/- 12.8%). However, the irregulars had virtually the same number of teeth as the regular attenders, 25.6 +/- 3.3 compared with 25.4 +/- 4.3. Irregular attenders had slightly deeper mean probing depths (2.9 +/- 0.4 versus 2.7 +/- 0.4 mm) but the prevalence and extent of attachment loss was no different between the groups. It was concluded that the prevalence and severity of destructive periodontal disease as indicated by periodontal attachment loss was not related to the regularity of dental attendance in the groups studied.

Pub Date Free Form 1994/ Volume 154 Issue 1 Start Page 47 Other Pages 61 Notes Place of Publication ISSN/ISBN 0048-9697 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Hydrochemical variations in the major, minor and trace element concentrations of a first order stream draining a plantation of sitka spruce (Picea sitchensis (Bong.) Carr.), subjected to felling, are described. The stream water is acidic and aluminium bearing as the area drained comprises thin, acidic, organic-rich soils. The chemical composition of the stream varies with time and the data is scattered owing to the complex hydrological, chemical and biological interactions involved. None the less, the catchment has the ability to damp down the chemical signal of the rainfall. There is no statistically significant correlation between rainfall and stream water chemistry for any of the components measured. Deforestation leads to increased concentrations of NO3, K, H+, the major elements and Al together with a decrease in alkalinity. The changes last for ~2-3 years: conditions then revert to pre-felling levels. These results fit well with previous findings in that deforestation leads to the disruption of the biochemical functioning of the catchment (releasing nitrate and potassium and acidifying the soil water). The major element changes are linked to increased leaching of the soil waters as a consequence of changing hydrology (evapotranspiration is probably reduced and the catchment soils wet up). However, the variations in Al, dissolved organic carbon, Br and I are less than would be anticipated based on previous results for a companion study of the main drainage area. Dissolved organic carbon, Fe, Cd, Y and La show increases, but these changes occur after the felling is complete and there has been no return to pre-felling values 3 years on. The applicability of classically used cation exchange theory for the soil, the basis for many of the conclusions derived in the soil acidification debate, is questioned and found to be highly suspect.

The discussion begins with a summary of survey findings on the nature and extent of alcohol and drug use, including prevalence and patterns of use and associated problems. This summary is followed by a discussion of the correlates of substance use and problems, including demographic characteristics, personality factors, year in college and grade point average, college residence, motivation, and attitudes. The most popular substance used by college students is alcohol, used by about 90% of students at least once a year. Heavy alcohol use is also prevalent, and is associated with serious, acute problems. Although alcohol use has decreased somewhat in recent years, much larger declines in use have been recorded for illicit drugs. The major proportion of research on substance use in this population has been devoted to alcohol; more information is needed on the prevalence, patterns, and correlates of illicit drug use. Suggestions for coping with problems of campus alcohol use/abuse are offered.

DESIGN: A descriptive study of a crossover type. October 1992. SETTING: Primary Health care. PARTICIPANTS: 381 general physicians and paediatricians from Guipuzcoa province. MEASUREMENTS AND MAIN RESULTS: A self-filled questionnaire was distributed at Health Centres for subsequent return by mail. The reply rate was 60.89%, 42.3% were smokers; 33.6%, ex-smokers. 43% of smokers smoked in the Centre; 2% in front of patients. We found significant differences (p < 0.05) with a study carried out in 1988, where doctors who smoked were 52.4%, ex-smokers 19% and doctors who smoked in front of patients, 18.2%. 45.7% of women smoked, 39.2% of men. 78% of the doctors under study stated that they questioned patients about tobacco consumption. 95.2% did so when patients had specific pathologies. CONCLUSIONS: There has been a significant decline in tobacco smoking by doctors in Guipuzcoa. There are more women than men smokers. There is a higher proportion of ex-smokers among doctors than in the population as a whole. There has been a positive change of attitude as to smoking in front of patients. Centres should become more involved in the struggle against tobacco by offering to set up dependency counselling groups.

Effects of acid mist on mature grafts of Sitka spruce: Part I - Frost hardiness and foliar nutrient concentrations	1994	Sheppard, L.J., Institute of Terrestrial Ecology, Bush Estate, Penicuik, Midlothian EH26 0QB, United Kingdom	Read more...

Pub Date Free Form 1994/ Volume 85 Issue 2 Start Page 229 Other Pages 238 Notes Place of Publication ISSN/ISBN 0269-7491 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Mature grafts of five clones of Sitka spruce (Picea sitchensis Bong. Sarg.) were exposed to simulated acid mist composed of an equimolar mixture of sulphuric acid and ammonium nitrate at pH 2.5 and pH 5.0 in open-top chambers from May to November 1991. Treatments were applied on consecutive days, four times a week. The pH 2.5 treatment provided an overall dose three times higher than that received by forests in upland areas of Britain. Frost hardiness was assessed in November by freezing detached current year shoots at a range of temperatures and assessing the rate of electrolyte leakage Foliar nutrient concentrations were determined on the same shoots. Acid mist at pH 2.5 significantly reduced frost hardiness in four of the five clones; the temperature causing 50% shoot death (LT50) was increased by 0 to 7Â°C. The clones varied in their level of hardiness, one clone being exceptionally frost sensitive. The frost hardiness of the frost sensitive clone was found to be less perturbed by acid mist than the hardiness of the more frost resistant clones. Mature grafts showed a smaller reduction in hardiness at an equivalent dose than that found previously with Sitka spruce seedlings. Compared with seedlings, grafts had lower absolute concentrations of foliar sulphur. Exposure to acid mist at pH 2.5 increased %S in current year foliage by <0.05% compared with absolute increases of more than 0.10% in current year foliage of seedlings. We conclude that the effect of acid mist on frost hardiness is likely to be less on mature trees than on seedlings and that the increased frost risk to mature trees of Sitka spruce from occult deposition alone is small.

Pub Date Free Form 1993/ Volume 8 Issue 3 Start Page 299 Other Pages 311 Notes Place of Publication ISSN/ISBN 1053-4725 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Current measures of microbe-mediated biogeochemical processes in sediments were examined for their potential use as indicators of heavy metal ecotoxicity in both river sediments and bacterial cultures. Assays were carried out with HgCl2, CuSO4, and 3CdSO4.8H2O added to sediment samples and bacterial cell suspensions at concentra,ions ranging from 0.1 to 10 mM and 0.1 Î¼M to 1 mM, respectively. Chemoautotrophic CO2, fixation by Elbe River sediment microbiota was most sensitive to Hg2+ and Cd2+, but not to Cu2+. Among the estimates of heterotrophic productivity, incorporation of leucine into cellular protein showed clearer dose responses than incorporation of thymidine into bacterial DNA. Thymidine incorporation was highly resistant to and even stimulated by metal ions, particularly in starved and anaerobic cultures of a test strain of Vibrio arguillarum. Similar metal ion induced 'overshoot' responses beyond the levels of untreated controls were noted for mineralization of 14C-glucose by V. anguillarum and, in the case of Cd2+, also in sediment. As a less complex measure of microbial respiratory activity, succinate dehydrogenase (SDH) showed normal dose responses without stimulatory effects, as long as acterial cell homogenates were assayed. Despite this result, it is concluded that levels of SDH in natural sediment microbiota are inevitably affected by metal-induced processes of selection and enzyme synthesis, and would thus fail to provide an appropriate measure of metal ecotoxicity. The final conclusion is that current parameters of microbial production and activity often reveal dose responses that do not fulfill basic requirements of ecotoxicity testing in metal-polluted sediments.

Mean carbon monoxide fractions (% by volume) of hookah smoke, using domestic charcoal were 0.38 +/- 0.07 (large hookah; unfiltered); 1.40 +/- 0.43 (small hookah; unfiltered); 0.34 +/- 0.06 (large hookah; filtered); 1.36 +/- 0.35 (small hookah; filtered) and 0.41 +/- 0.08 (cigarette smoke). The highest fractions were obtained with small size hookah and increase in size of hookah (i.e., volume of air in water base, fire bowl volume, pipe length, etc.) reduced the CO fraction significantly (P < 0.001). The fractions of cigarette lie between large and small hookah. The fractions vary slightly with different varieties of tobacco, e.g., CO fractions with Dera wala tobacco are significantly low (P < 0.05). Use of commercial charcoal gives significant rise in CO fractions (P < 0.001). Comparison of filtered and unfiltered smoke shows no significant difference in values. We conclude that the CO hazard is as high with hookah smoking as with cigarette smoking.

DATA SOURCES: MEDLINE and bibliographies from identified publications. STUDY SELECTION: In part 1, published studies of indoor air quality were included if they reported a mean concentration of carbon monoxide, nicotine, or particulate matter from measurements taken in one or more bars, restaurants, offices, or residences with at least one smoker. In part 2, published epidemiologic studies that reported a risk estimate for lung cancer incidence or mortality in food-service workers were included if they controlled, directly or indirectly, for active smoking. DATA EXTRACTION: In part 1, a weighted average of the mean concentration of carbon monoxide, nicotine, and respirable suspended particulates reported in studies was calculated for bars, restaurants, offices, and residences. In part 2, the relative lung cancer risk for food-service workers compared with that for the general population was examined in the six identified studies. DATA SYNTHESIS: Levels of environmental tobacco smoke in restaurants were approximately 1.6 to 2.0 times higher than in office workplaces of other businesses and 1.5 times higher than in residences with at least one smoker. Levels in bars were 3.9 to 6.1 times higher than in offices and 4.4 to 4.5 times higher than in residences. The epidemiologic evidence suggested that there may be a 50% increase in lung cancer risk among food-service workers that is in part attributable to tobacco smoke exposure in the workplace. CONCLUSIONS: Environmental tobacco smoke is a significant occupational health hazard for food-service workers. To protect these workers, smoking in bars and restaurants should be prohibited.
