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.

Das Verschwinden der Schmetterlinge

Der Hang liegt am Keilstein bei Regensburg, mitten in einem Naturschutzgebiet. Jan Christian Habel besucht diesen Ort gern mit seinen Studenten. Habel ist Schmetterlingsexperte, er hat einen Lehrstuhl für Terrestrische Ökologie an der Technischen Universität München. Mitte Juli war Habel wieder mit einer Gruppe am Hang. Es war eine traurige Expedition. „Seltene Falterarten waren nicht mehr vorhanden“, sagt er. „Wir haben nur Trivialarten gefunden.“ Aber auch von diesen eigentlichen häufig vorkommenden Schmetterlingen entdeckten Habel und die Studenten viel weniger Exemplare als sonst.

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.

Our Daily Poison - By Dr Rosemary Mason

In 2010, my life changed when Dr Henk Tennekes and I traded books. His was: The systemic insecticides: a disaster in the making and ours was: The Year of the Bumblebee: Observations in a small Nature Reserve. Dr Henk Tennekes, an independent toxicologist based in the Netherlands, was the first researcher to recognise the extreme toxicity of low levels of systemic neonicotinoid insecticides that have become widespread in the environment.

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.

Non-alcoholic fatty liver disease in rats following chronic exposure to an ultra-low dose of Roundup herbicide

The impairment of liver function by low environmentally relevant doses of glyphosate-based herbicides (GBH) is still a debatable and unresolved matter. Previously we have shown that rats administered for 2 years with 0.1 ppb (50 ng/L glyphosate equivalent dilution; 4 ng/kg body weight/day daily intake) of a Roundup GBH formulation showed signs of enhanced liver injury as indicated by anatomorphological, blood/urine biochemical changes and transcriptome profiling.

Butterflies on both sides of the Atlantic Ocean are in rapid decline

Urban populations of 28 butterfly species have fallen 69 percent across the UK since 1995, while in America monarch butterflies are down 80 percent since the mid-1990s and 27 percent since this time last year. The decline is worrying, say scientists, because butterflies are recognized as environmental indicators due to their rapid responses to small changes in climate and habitat.

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.
