Magical Contamination by Antoinre Bridier-Nahmias is an artistic documentation of mould and its diverse colors and textures captured in petri dishes.
Being a substance which is in general an unwelcome guest, the series shows the beauty and fascination of these mould specimens in a new angle and makes you appreciate its light pastels and geometric shapes.
Recreational marijuana has been legalized in four states, but that doesn’t mean it’s a tested consumer product. Some of those potent buds are covered in fungus while others contain traces of butane, according to an analysis of marijuana in Colorado.
Last May, after people began getting sick from edible marijuana products, the state of Colorado began requiring all products to be tested. Washington has mandated testing too, with a detailed checklist of items to analyze, including potency, contaminants, moisture and microbiology.
Deep Water Horizon cleanup efforts made Gulf 52 times more toxic December 4, 2012
If the 4.9 million barrels of oil that spilled into the Gulf of Mexico during the 2010 Deep Water Horizon spill was a ecological disaster, the two million gallons of dispersant used to clean it up apparently made it even worse – 52-times more toxic. That’s according to new research from the Georgia Institute of Technology and Universidad Autonoma de Aguascalientes (UAA), Mexico.
The study found that mixing the dispersant with oil increased toxicity of the mixture up to 52-fold over the oil alone. In toxicity tests in the lab, the mixture’s effects increased mortality of rotifers, a microscopic grazing animal at the base of the Gulf’s food web. The findings are published online by the journal Environmental Pollution and will appear in the February 2013 print edition.
Using oil from the Deep Water Horizon spill and Corexit, the dispersant required by the Environmental Protection Agency for clean up, the researchers tested toxicity of oil, dispersant and mixtures on five strains of rotifers. Rotifers have long been used by ecotoxicologists to assess toxicity in marine waters because of their fast response time, ease of use in tests and sensitivity to toxicants. In addition to causing mortality in adult rotifers, as little as 2.6 percent of the oil-dispersant mixture inhibited rotifer egg hatching by 50 percent. Inhibition of rotifer egg hatching from the sediments is important because these eggs hatch into rotifers each spring, reproduce in the water column, and provide food for baby fish, shrimp and crabs in estuaries.
“Dispersants are preapproved to help clean up oil spills and are widely used during disasters,” says UAA’s Roberto-Rico Martinez, who led the study. “But we have a poor understanding of their toxicity. Our study indicates the increase in toxicity may have been greatly underestimated following the Macondo well explosion.”
Martinez performed the research while he was a Fulbright Fellow at Georgia Tech in the lab of School of Biology Professor Terry Snell. They hope that the study will encourage more scientists to investigate how oil and dispersants impact marine food webs and lead to improved management of future oil spills.
“What remains to be determined is whether the benefits of dispersing the oil by using Corexit are outweighed by the substantial increase in toxicity of the mixture,” says Snell, chair of the School of Biology. “Perhaps we should allow the oil to naturally disperse. It might take longer, but it would have less toxic impact on marine ecosystems.
Leading scientists recently identified a dozen chemicals as being responsible for widespread behavioral and cognitive problems. But the scope of the chemical dangers in our environment is likely even greater. Why children and the poor are most susceptible to neurotoxic exposure that may be costing the U.S. billions of dollars and immeasurable peace of mind.
Forty-one million IQ points. That’s what Dr. David Bellinger determined [in 2012] Americans have collectively forfeited as a result of exposure to lead, mercury, and organophosphate pesticides. …
Last month, more research brought concerns about chemical exposure and brain health to a heightened pitch. Philippe Grandjean, Bellinger’s Harvard colleague, and Philip Landrigan, dean for global health at Mount Sinai School of Medicine in Manhattan, announced to some controversy in the pages of a prestigious medical journal that a “silent pandemic” of toxins has been damaging the brains of unborn children. The experts named 12 chemicals—substances found in both the environment and everyday items like furniture and clothing—that they believed to be causing not just lower IQs but ADHD and autism spectrum disorder. Pesticides were among the toxins they identified.
These photos were taken in Cairns last week, showing dredge spoil being dumped in the Great Barrier Reef’s waters. Maintenance dredging is a necessary activity at big existing ports like Cairns - but simply dumping the dredge spoil in the Reef’s waters is not.
Enough is enough. Please sign the petition to ban dumping in the Reef:
