Stichproben in kleinen Gewässern am Bodensee haben eine alarmierende Artenarmut ergeben

Damit hatte niemand gerechnet: Die Artenvielfalt in kleineren Gewässern am Bodensee scheint sehr gering zu sein. Irmtraud Schuster, die Umweltdezernentin des Landratsamtes Bodenseekreis, räumt ein, dass die Ergebnisse erster Prüfungen sie schon alarmiert hätten. Doch habe das Institut für Seenforschung nur Stichproben gezogen und lediglich – den allerdings wichtigen – Bereich der wirbellosen bodenlebenden Tiere untersucht. Ursache könnten Pflanzenschutzmittel sein, die aus dem Obstbau in die Bäche getragen werden.

'Dramatic' decline in European birds linked to industrial agriculture

The number of birds in Germany and Europe has dropped significantly over the past 30 years, according to the German government. In Germany, one-third of all bird species have seen "significant population declines" since the end of the 1990s, said the government in response to a question about the plight of birds across Europe put forward by the Greens. "The situation of birds is dramatic," said Steffi Lemke, a German Green Party lawmaker.

Schweizweit sind kleinere Fliessgewässer mit Giften verseucht

Sie sind unscheinbar und doch überall vorhanden. Kleine Bäche prägen das Landschaftsbild. Sie machen rund drei Viertel des 64 000 Kilometer grossen Schweizer Gewässernetzes aus. Doch sie sind oft kein guter Lebensraum mehr. Gründe sind Pestizide, die das Wasser für Wassertiere vergiften. Insbesondere am Anfang von Regenphasen gehen die Ausschläge hoch. Aber auch zwischen diesen Höchstwerten gibt es in vielen Bächen der Schweiz nachweislich Rückstände von Pestiziden. Dies zeigt eine Studie, die im Auftrag des Bundesamts für Umwelt realisiert wurde.

River Irwell suffers serious pollution for the second time in three weeks

The River Irwell appears to have been polluted for a second time in three weeks. Countless fish and insects died following reports a pesticide which was poured down a drain and devastated a 25-mile stretch of the river from Rawtenstall into Manchester city centre earlier this month. Now a second incident has been reported on a section of the Irwell north of Bury. The incident has been reported to the Environment Agency. Mike Duddy, chief executive of the Mersey Basin Rivers Trust, said virtually no river life had survived the previous incident.

Honeybees encounter danger due to lingering and wandering pesticides

Honeybees -- employed to pollinate crops during the blooming season -- encounter danger due to lingering and wandering pesticides, according to a new Cornell University study that analyzed the bee's own food. Researchers used 120 pristine honeybee colonies that were placed near 30 apple orchards around New York state. After allowing the bees to forage for several days during the apple flowering period, the scientists examined each hive's "beebread" -- the bees' food stores made from gathered pollen -- to search for traces of pesticides.

Het water van Delfland blijft ook in 2016 een bestrijdingsmiddelenriool

De waterkwaliteitsverbetering van de afgelopen jaren in glastuinbouwgebieden in het Hoogheemraadschap van Delfland stagneert. Dat is de belangrijkste conclusie die Delfland heeft getrokken uit de Waterkwaliteitsrapportage over 2016. Uit de meetresultaten over 2016 blijkt dat de concentraties bestrijdingsmiddelen en meststoffen (stikstof en fosfaat) nog steeds te hoog zijn en niet verminderen. De hoogste en meeste normoverschrijdingen worden aangetroffen in de glastuinbouwgebieden.

Three rivers in the Cameron Highlands declared 'dead'

Regional Environment Awareness Cameron Highlands (REACH) president Ramakrishnan Ramasamy said most rivers in the highland, known for its tourism and agriculture, are heavily polluted. He said data from the Department of Environment (DoE) and the Drainage and Irrigation Department (DID) showed that only about 10 per cent of 123 rivers were in Class I and Class II, while the remainder were in Class III and Class IV. He also said three rivers had been declared biologically dead, and came under Class V of the classification.

Pesticide Impact on Bay Delta Fish Could Be Greater Than Realized

New monitoring in the Bay Delta shows that the water is a soup of urban and agricultural insecticides, herbicides and fungicides. When combined, pesticides at sublethal levels can have deadly synergistic effects on fish. “The Sacramento River and San Joaquin River have been monitored for years, but historically there has been little monitoring in the Delta itself,” says Michelle Hladik, an environmental chemist who leads the USGS Pesticide Fate Research Group.

Alarmierende Zustände in Schweizer Bächen

Umweltorganisationen haben vom Bundesrat angesichts der alarmierenden Resultate der Gewässeruntersuchungen einen wirkungsvollen Pestizidreduktionsplan gefordert. Denn über die Nahrungsmittelkette sei auch der Mensch vom giftigen Pestizidcocktail betroffen. Pro Natura spricht von alarmierenden Zuständen. Der Unmut in der Bevölkerung über den Pestizidmix in den Bächen sei gross, schreibt die Naturschutzorganisation in einer Mitteilung vom Dienstag. Dies zeigten auch zwei kürzlich lancierte Volksinitiativen für sauberes Trinkwasser und gegen synthetische Pestizide.

Persistently high pesticide levels found in small Swiss streams

Small watercourses are contaminated with large numbers of herbicides, fungicides and insecticides. A study commissioned by the Federal Office for the Environment and published today shows that the legal requirements specified for water quality are not met in any of the five Swiss streams investigated. Indeed, thresholds for acute toxicity to aquatic organisms were also exceeded. Bioassays indicate that biological communities are adversely affected by mixtures of substances.
