One of them containing 5'-phosphate group to be activated and 3'-phosphate group of the other being substituted with ethoxy-, buthylamino-, morpholino- or ethyl glycinate residues. Water-soluble carbodiimide (EDAC) proved to be more efficient in the phosphate group activation than N-hydroxybenzotriazole ester (yields of substituted pyrophosphates 35-80 and 10-15% respectively). The substituted pyrophosphate bong is quite stable in neutral aqueous solution. Mild conditions of selective cleavage of this bond yielding the initial oligonucleotides were found.

State assets of public water pipelines and sewerage were transferred to towns and municipalities and joint stock companies were established. Two types of companies appeared-operational and ownership companies. The first type is the operational company that operates the infrastructure assets of public water pipelines and sewerage. These assets stay in the ownership of municipalities. A long term operational contract is agreed that solves the relationship between the owners and operators. The second type is the ownership company that directly owns the infrastructure assets of public water pipelines. Towns and municipalities in this case became shareholders of those companies. At the end of nineties, big international companies bought shares of both operational and ownership companies. Municipalities have to, by law, ensure the operation of public water pipelines. However, by the sale of shares they have lost a possibility to participate in decision making. A question about future co-operation between towns and municipalities and ownership companies appears. An example of the North Moravian Water and Sewerage Works Company was used to describe a possible way of co-operation between a private company and the municipalities on whose territory the company operates. Contracts between the ownership company and particular municipalities were agreed. This solution turned out to be complicated, so the municipalities affiliated and established Water Management Association. The objective of the Association is to promote common interests of the municipalities in relation to the water company. A contract was agreed between the Water Management Association and the company about co-operation in the area of water tariff setting and public waterworks' development.

Pub Date Free Form / Volume 21 Issue 2 Start Page 145 Other Pages 158 Notes Place of Publication ISSN/ISBN 1066-2936 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Professional diving fishermen in the Pescadores Archipelago (119.30 degrees W, 23.30 degrees N) dive with a simple hookah system. 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.

After removal of the plants and the litter layer, soil samples were obtained at 15-cm intervals to a total depth of 90 cm. Elevated SO4 concentrations caused by the simulated H2SO4 rain were most pronounced for the top 15 cm, but extended down to 45 cm (maple) or 75 cm (alder). There were no effects on SO4 concentrations at a depth of 75 to 90 cm. This confirmed the existence of a sulfate front between 20 cm and 100 cm, as postulated earlier on the basis of extracted soil solutions. Decreases in Mg and Ca concentrations, base saturation, and soil pH were limited to the uppermost 15 cm and, in most cases, to the pH 3.0 treatment. Concentrations of Mg and Ca for the pH 3.0 treatments were greater than control at a depth of 15 to 30 cm, indicating transport of these cations from the soil surface. Concentrations of Na and K, and cation exchange capacity, were not affected by simulated H2SO4 rain. Elevated concentrations of NO3 and extractable Zn throughout the alder systems indicated (1) either increased rates of symbiotic N-fixation or decreased rates of N immobilization; and (2) mobilization of Zn by all acid rain treatments.

Forest productivity, ground-water quality, and surface waters might all be affected. To document and quantify ecosystem response to the onset of acid precipitation, simulated sulfuric acid (H2SO4) rain was applied to model forest plots of sugar maple (Acer saccharum Marsh.) and red alder (Alnus rubra Bong). One set of four plots (two alder and two maple) received a control rain consisting of a stock solution equilibrated with atmospheric CO2 to approximately pH 5.7. For three sets of four plots, sufficient H2SO4 was added to the stock solution to lower the pH to 4.0, 3.5, or 3.0. Nozzles were used to apply simulated acid rain at the rate of 2.8 mm/hour (maple) or 3.7 mm/hour (alder) for 3 hours/day, 3 days/week, throughout the year. Water samples were collected above and below the canopy, below the litter layer, and from 20-cm and 1-m depths below the surface of the soil. While constituents of the throughfall were similar to those of the simulated rain, the litter leachate (the actual input to the soil) had consistently higher concentrations of SO42-, Ca2+, and Mg2+, and higher pH, than the acid rain. For the first 6 months, SO42- adsorption by the soil prevented any apparent differences in the SO42-, Ca2+, or Mg2+ concentrations or the pH of samples taken from a depth of 20 cm from plots receiving either acid or control treatments. Then, SO42- concentrations at this depth on plots receiving the most acidic rain (pH 3.0) became increasingly higher than on the other plots until, after 3 years, they were approximately equal to SO42- concentrations in the rain. Soil solutions from the pH 3.5 and 4.0 treatments responded similarly starting 10 months and 1 year, respectively, after initiation of exposure to acid rain. Increased Ca2+, Mg2+, and, to a lesser extent, K+ concentrations and lowered pH in solutions from the 20-cm depths occurred simultaneously with increased SO42- concentrations. At a depth of 1 m, no acid-rain-related effects were evident after 2.5 years exposure to pH 3.0 H2SO4 rain. Results showed that a hardwood canopy and litter layer can alter the input of chemicals to the soil from acid rain, that the relative sensitivity of ions to mobilization by acid rain is not the same for all components of an ecosystem, and that acid rain can alter the chemical composition of water within the root zone within a few years, even if the soil is a strong sulfate adsorber.

Pub Date Free Form 1995/ Volume 90 Issue 3 Start Page 363 Other Pages 370 Notes Place of Publication ISSN/ISBN 0269-7491 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Mature grafts of five Sitka spruce (Picea sitchensis (Bong.) Carr.) clones were exposed to simulated acid mist comprising an equimolar mixture of H2SO4 and NH4NO3 (16 and 0.01 mol m-3) at pH 2.5 and 5.0. Mist was applied to potted plants growing in open-top chambers on consecutive days, four times a week, at a precipitation equivalent of 1 mm per day. The total exposure to polluted mist was equivalent to three times that measured at an upland forest in SE Scotland. The aim of the experiment was to characterize the response of juvenile foliage produced by physiologically mature grafts (on seedling root stock) and compare it with the behaviour of juvenile foliage on seedlings. Development of visible foliar damage was followed through the growing season. Measurements of needle length, diameter, weight, surface area, surface wax weight and wettability were made on current year needles to determine whether particular foliar characteristics increased susceptibility to injury. Significant amounts (> 10%) of visible needle damage was observed on only one of the five clones. Damage was most severe on the clone with the most horizontal branch and needle habit, but over the five clones there was no relationship between angle of branch display and damage. Likewise no combination of needle characteristics (length, width, area, amount of wax) was indicative of potential susceptibility. A comparison with previous acid misting experiments using seedlings suggests that juvenile foliage on physiologically mature trees is equally susceptible to visible injury as juvenile seedling foliage. Date of budburst differed among clones, and in this experiment exerted the over-riding influence on development of injury symptoms. Foliage exposed to a combination of strong acidity and high sulphate concentrations over the few weeks immediately following budburst suffered most visible injury. The absence of significant amounts of visible damage in UK forests probably reflects the general low susceptibility to visible injury of Sitka spruce exposed to acid mist.

Our objectives were to look for the factors that influence lead burden in children aged 8-11 years. Methods: A cross-sectional population-based study took place in 1996-97 and included 400 children (200 of whom lived on the metal-polluted site). Results: The geometric mean of the blood-lead levels of children living on the polluted site was 39.5 Î¼g/l (95% CI = 36.3-43.1); that of the non-exposed children was 30.6 Î¼g/l (95% CI=27.8-33.6) (P<0.0001). Analysis of the variations in the mean blood-lead levels showed associations with: Distance from the smelting plants (mean blood-lead level fell by a factor of 1/1.3 (95% CI = 1/1.2-1/1.4) for each km from the smelter over the range of 1-3 km and was constant thereafter) and consumption of tap water (when the water pipes were made of lead, the mean blood-lead level of children who drank tap water was twice as high (95% CI=1.2-3.4) as that of children who did not). Conclusions: The children's blood-lead levels were essentially linked to two factors: Proximity to the smelters and drinking tap rather than bottled water. (C) 2000 Wiley-Liss, Inc.
