If you look just at the numbers, you might think autism rates are spiraling out of control. The rates seemed high enough at 1 in 150 in 2000, when public health officials started tracking a steady rise in the syndrome in the United States. And by the time estimates finally flatlined in 2012 at 1 in 68, many parents had embraced unfounded theories blaming vaccines for an autism “epidemic,” helping to fuel outbreaks of measles and other once rare diseases.
It was only in 2015 that the US Geological Survey first studied whether neonicotinoid residue shows up in streams (it does), and new research from the University of Iowa is the first to find it in drinking water. This new study tested water from drinking taps throughout Iowa City for neonicotinoid presence. Iowa City is on the smaller side, with an estimated population of fewer than 75,000, but its presence in a largely agricultural state makes it well-placed to see how nearby pesticide use can affect an urban area.
High exposure to pesticides as a result of living near farmers’ fields appears to increase the risk of giving birth to a baby with “abnormalities” by about 9 per cent, according to new research. Researchers from the University of California, Santa Barbara, compared 500,000 birth records for people born in the San Joaquin Valley between 1997 and 2011 and levels of pesticides used in the area. The average use of pesticides over that period was about 975kg for each 2.6sq km area per year.
Deskundigen die beweren dat fipronil niet schadelijk is, kijken vooral naar de korte termijn. Dat zeggen toxicoloog Henk Tennekes en landbouwkundig consultant Jelmer Buijs maandag in dagblad Trouw. Op de lange termijn hebben insecticiden zoals fipronil volgens hen wel degelijk negatieve gevolgen voor de gezondheid. Ze wijzen erop dat de effecten van kleine hoeveelheden gif zich in het menselijk lichaam opbouwen. Tennekes en Buijs spreken met hun waarschuwing de meerderheid van de deskundigen tegen, onder wie hoogleraar voedingsleer aan de Vrije Universiteit Martijn Katan.
The occurrence of pesticides intended for non-agricultural use was investigated in 206 dust samples drawn from vacuum-cleaner bags from residential flats in Italy. The results indicated the presence of imidacloprid (IMI) in 30% of the samples. According to the estimated dust intake in infants/toddlers aged 6–24 months (16–100 mg d−1) and cats (200 mg d−1), it was possible to obtain risk characterization with respect to the Acceptable Daily Intake (ADI) for IMI of 0.060 mg/kg body weight (bw) proposed by EFSA and the chronic Population Adjusted Dose (cPAD) of 0.019 mg/kg bw d−1 by US-EPA.
Onze rivieren bevatten te veel pesticiden, kwik en vlamvertragende stoffen. Toch verorberen we jaarlijks nog 30 ton paling uit onze rivieren. ‘Onverantwoord’, zegt bioloog Claude Belpaire. ‘Vissers krijgen duidelijk de boodschap dat ze het best geen vis uit onze rivieren eten. Maar elk jaar wordt er 30 ton paling uit onze Vlaamse rivieren meegenomen voor consumptie. Die ontrading heeft dus weinig effect’, zegt Claude Belpaire, bioloog van het Instituut Natuur- en Bosonderzoek (INBO) en gespecialiseerd in de leefomstandigheden en gezondheidstoestand van paling.
Every year toward the beginning of rainy season, dense clouds of black salt marsh mosquitoes begin rising from the Everglades and coastal wetlands and descending upon Miami. For years, Miami and the Keys have fought back with a powerful tool: permethrin, a pesticide effective at killing the insects before they can make life miserable for South Florida.
Hyperactivity Disorder or ADHD is a disorder of modern times, affecting more and more of America's children. While the origins of ADHD are surprising and disturbing, alleviating or even reversing symptoms is possible. Twelve percent of U.S. children and teens had a diagnosis of Attention Deficit/Hyperactivity Disorder (ADHD) in 2011, a number that has jumped by 43 percent since 2003, according to a large national study based on parental reports of an ADHD diagnosis according to a recent analysis.
Eating food with high levels of pesticides has an adverse effect on the brain, according to a review of existing scientific evidence commissioned by the European Parliament. The MEPs wanted to know whether organic food was healthier than conventionally grown crops and asked experts to look at the relevant research.
Until a few decades ago, the popular but falsely reassuring belief was that babies in the womb were perfectly protected by the placenta and that children were just “little adults,” requiring no special protections from environmental threats. We now know that a host of chemicals, pollutants and viruses readily travel across the placenta from mother to fetus, pre-polluting or pre-infecting a baby even before birth.
