From September 1985 to March 1992, 804 amniotic fluid samples from 64 different diagnostic centres of the Federal Republic of Germany were sent to our laboratory exclusively for rapid karyotyping. The average time needed for notification of the analysed karyotype was 4·65 days when the ‘pipette method’ was used for chromosome harvesting and 5·97 days when the ‘in situ’ technique was used. The overall incidence of chromosome aberrations was 15·3 per cent. Data are presented about the likelihood of abnormal ultrasound findings being caused by chromosome aberrations. These findings include polyhydramnios, oligohydramnios, growth retardation, fetal effusions, neural tube defects, craniofacial defects, heart defects, gastroschisis and omphalocele, gastrointestinal tract defects, urinogenital defects, and limb defects. In future, such data need to contain larger numbers of cases for each week of gestation. This will improve the risk evaluation for each case with abnormal ultrasound findings, which should lead to better management during pregnancy, delivery, and postnatal care for those who require rapid karyotyping. 相似文献

This study is based on the theses that
- early diagnosis is indispensable for the management of environmental problems in the context of precautionary policy, which have the character of a “creeping disaster” and that
- the public must play the active role that is adequate within a democratic society.

ABSTRACT: Many of the most productive fishing grounds in the United States are estuaries and bays which are located near population and industrial centers, and therefore subjected to pollution. Observations made on 17 fish species from commercial catches harvested in north Biscayne Bay, Florida, an urban area, showed high numbers of individuals suffering from abnormalities and diseases. Seven groups of disorders most frequently affected bottom feeders. Fin and integumental hemorrhages occurred in all individuals in 26 of 43 catches of Mugil cephalus (striped mullet), and in all individuals in 24 of 30 catches of Micropogon undulatus (Atlantic croaker). Disorders occurring consistently in a location exposed to pollutants, but uncommon in other areas of the species' range, point to environmental stress as a probable cause. 相似文献

Zusammenfassung Der WWF (World Wide Fund for Nature), Initiator und Tr?ger des Donau-Karpaten-Programms, besch?ftigt sich seit Beginn des
Kosovo-Konfliktes mit den Auswirkungen der kriegerischen Auseinandersetzungen auf Natur und Mensch und versucht, die Welt?ffentiichkeit
entsprechend zu informieren. Ende Juli 1999 hat der WWF International eine Mission, bestehend aus unabh?ngigen Toxikologinnen
und ?lexperten, an die Donau entsandt. Unter der Leitung von Philip Weller, dem Direktor des WWF Donau-Karpaten-Programms,
wurden drei Tag lang Industriekomplexe besichtigt und Gespr?che mit Betroffenen geführt. Die Reise führte das Team nach Panćevo
und Novi Sad, und damit zu den Schwerpunkten der zerst?rten Chemie- und Petrochemischen Komplexe. In den betroffenen Werken,
HIP AZOTARA, Panćevo und NIS ?lraffinerie, Novi Sad wurde das Team von den jeweiligen Werkleitern geführt. Gespr?che fanden
statt mit dem Bürgermeister von Panćevo und Vertretern des Gesundheitsamtes in Belgrad. Es war dem Team m?glich, Boden- und
Wasserproben zu nehmen und zu analysieren. Damit liegen den Autoren unabh?ngige Analysenergebnisse vor, die es gestatten,
eine erste, orientierende Einsch?tzung der Kontaminationen vorzunehmen.

Concentrations of neutral poly- and perfluoroalkyl substances (PFASs), such as fluorotelomer alcohols (FTOHs), perfluoroalkane sulfonamides (FASAs), perfluoroalkane sufonamidoethanols (FASEs), and fluorotelomer acrylates (FTACs), have been simultaneously determined in surface seawater and the atmosphere of the North Sea. Seawater and air samples were taken aboard the German research vessel Heincke on the cruise 303 from 15 to 24 May 2009. The concentrations of FTOHs, FASAs, FASEs, and FTACs in the dissolved phase were 2.6–74, <0.1–19, <0.1–63, and <1.0–9.0 pg L?1, respectively. The highest concentrations were determined in the estuary of the Weser and Elbe rivers and a decreasing concentration profile appeared with increasing distance from the coast toward the central part of the North Sea. Gaseous FTOHs, FASAs, FASEs, and FTACs were in the range of 36–126, 3.1–26, 3.7–19, and 0.8–5.6 pg m?3, which were consistent with the concentrations determined in 2007 in the North Sea, and approximately five times lower than those reported for an urban area of Northern Germany. These results suggested continuous continental emissions of neutral PFASs followed by transport toward the marine environment. Air–seawater gas exchanges of neutral PFASs were estimated using fugacity ratios and the two-film resistance model based upon paired air–seawater concentrations and estimated Henry's law constant values. Volatilization dominated for all neutral PFASs in the North Sea. The air–seawater gas exchange fluxes were in the range of 2.5?×?103–3.6?×?105 pg m?2 for FTOHs, 1.8?×?102–1.0?×?105 pg m?2 for FASAs, 1.1?×?102–3.0?×?105 pg m?2 for FASEs and 6.3?×?102–2.0?×?104 pg m?2 for FTACs, respectively. These results suggest that the air–seawater gas exchange is an important process that intervenes in the transport and fate for neutral PFASs in the marine environment. 相似文献

For analysing element input into ecosystems and associated risks due to atmospheric deposition, element concentrations in moss provide complementary and time-integrated data at high spatial resolution every 5 years since 1990. The paper reviews (1) minimum sample sizes needed for reliable, statistical estimation of mean values at four different spatial scales (European and national level as well as landscape-specific level covering Europe and single countries); (2) trends of heavy metal (HM) and nitrogen (N) concentrations in moss in Europe (1990–2010); (3) correlations between concentrations of HM in moss and soil specimens collected across Norway (1990–2010); and (4) canopy drip-induced site-specific variation of N concentration in moss sampled in seven European countries (1990–2013). While the minimum sample sizes on the European and national level were achieved without exception, for some ecological land classes and elements, the coverage with sampling sites should be improved. The decline in emission and subsequent atmospheric deposition of HM across Europe has resulted in decreasing HM concentrations in moss between 1990 and 2010. In contrast, hardly any changes were observed for N in moss between 2005, when N was included into the survey for the first time, and 2010. In Norway, both, the moss and the soil survey data sets, were correlated, indicating a decrease of HM concentrations in moss and soil. At the site level, the average N deposition inside of forests was almost three times higher than the average N deposition outside of forests. 相似文献
