New EPA Assessment: Neonicotinoid Pesticides Pose Serious Risks to Birds, Aquatic Invertebrates

The U.S. Environmental Protection Agency released multiple scientific assessments today that found commonly used neonicotinoid pesticides can kill and harm birds of all sizes. Separate analyses also found the pesticides pose significant danger to aquatic invertebrates, which play a crucial role in supporting larger ecosystems. The troubling assessments come on the heels of earlier EPA analyses and thousands of scientific studies that have identified substantial risks to pollinators and aquatic invertebrates from this class of pesticides.

Eight English rivers are polluted with neonicotinoid pesticides

Rivers in England are contaminated with powerful insecticides, new testing has revealed, increasing concerns over the impact of the toxic chemicals on fish and birds. Eight rivers in England are heavily contaminated with neonicotinoid pesticides. Two of the rivers, the Waveney on the border between Norfolk and Suffolk, and the Tame in the West Midlands, had an “acute level” of pollution, according to tests conducted by the Environment Agency last year.

Insect decline: the biodiversity of the entire world is at stake

Bees and butterflies are experiencing widespread population decline, creating public concern in recent years. Data collected in Germany suggest that it’s not just bees and butterflies at risk: insect populations overall have plummeted by more than 75 percent since 1989. Scientists have known about the population decline for several years. However, they didn’t know how many species were declining, and they didn’t expect it to be happening so fast.

Onze landbouwgrond is zo dood als een pier

Het zijn niet alleen insecten en vogels boven de grond die last hebben van bestrijdingsmiddelen. In de bodem waar planten en gewassen groeien, werkt het gif net zo goed. Je hoort weinig over het bodemleven dat zich daar afspeelt. Maar het is essentieel. Miljoenen bacteriën, schimmels en allerlei andere bodemdiertjes, van aaltjes tot regenwormen, zorgen ervoor dat planten voedingsstoffen kunnen opnemen, dat er genoeg lucht in de bodem zit om gewassen te kunnen verbouwen en dat er voldoende gangetjes zijn waardoor de regen kan wegstromen.

Oorzaak van insectensterfte is al bekend: chemische bestrijdingsmiddelen

Toxicoloog Henk Tennekes is blij dat er eindelijk onrust ontstaat over de insectensterfte. Maar de belangrijkste boodschap blijft volgens hem achterwege: het zijn recente, chemische bestrijdingsmiddelen (neonicotinoïden) die de insecten doden. ‘Die moeten direct van de markt.’

Negative impacts of neonicotinoids in aquatic environments are a reality

Initial assessments that considered these insecticides harmless to aquatic organisms may have led to a relaxation of monitoring efforts, resulting in the worldwide contamination of many aquatic ecosystems with neonicotinoids. The decline of many populations of invertebrates, due mostly to the widespread presence of waterborne residues and the extreme chronic toxicity of neonicotinoids, is affecting the structure and function of aquatic ecosystems. Consequently, vertebrates that depend on insects and other aquatic invertebrates as their sole or main food resource are being affected.

The historic disaster in regulatory toxicology: the adoption of the ADI concept

Henk Tennekes refers to last century’s fifties, wherein the Germans Hermann Druckrey (1904-1994) and his friend, Chemistry Nobel laureate (1939) Adolf Butenand (1903-1995), advocated in the international community for a risk-prevention policy of dose-effect research for all pesticides. They wanted to prevent irreversible effects of pesticides. On the other hand there was the French René Truhaut, who advocated for the acceptable daily intake as the risk-management strategy for pesticide allowance for practical use.

Jean-Marc Bonmatin calls for a ban on neonicotinoid insecticides

Neonicotinoid pesticides pose severe threats to ecosystems worldwide, according to new information contained in an update to the world’s most comprehensive scientific review of the ecological impacts of systemic pesticides. The Task Force on Systemic Pesticides (TFSP) released the second edition of its Worldwide Integrated Assessment of the Effects of Systemic Pesticides on Biodiversity and Ecosystems today in Ottawa, Canada. It synthesizes more than 500 studies since 2014, including some industry-sponsored studies.

Jean-Marc Bonmatin pleit voor een verbod op de neonicotinoïden

Neonicotinoide pesticiden (neonics) vormen een grote bedreiging voor de ecosystemen wereldwijd. Dat blijkt opnieuw uit een geactualiseerde uitgave van ’s werelds meest uitgebreide wetenschappelijke evaluatie van de ecologische gevolgen van systemische pesticiden. De Task Force on Systemic Pesticides (TFSP) publiceerde in Ottowa, Canada de 2e editie van de Worldwide Integrated Assessment of the Effects of Systemic Pesticides on Biodiversity and Ecosystems. Het omvat meer dan 500 studies sinds 2014, waarvan ook enkele door de industrie gesponsorde studies.
