Radioactive Waste and Heavy Metal Clean Up at Hobsonville, Auckland

The New Zealand Defence Force (NZDF) has pledged to clean-up contaminated land at Hobsonville airport prior to the land being sold for commercial development or housing.

In 2001 the NZDF commissioned a audit of the base which revealed that some areas were "slightly contaminated with radioactivity from old, buried instruments and other areas were contaminated with heavy metals and other pollutants." Those pollutants include lead and copper in the shooting range, spilled oil and other chemicals.

The radioactivity comes from radium 266 used in luminous markings and it has already been deposited in containers. In the 1950s burying such instruments was an accepted disposal method.

Remediation work will include the removal of soil to a licensed disposal facility and cleaning of some areas.

Many sites in the Auckland region are also contaminated with chemicals left behind from agricultural activities which caused a furore recently. More to follow on this....

Councils Using Banned Endosulfan on Playing Fields

The Green Party has named and shamed 18 councils in New Zealand that spray Endosulfan on playing fields. The list includes

6 City Councils

• Dunedin
• Hamilton
• Manukau
• Napier
• Nelson
• Wellington

12 District Councils

• Hauraki
• Manawatu
• Masterton
• Matamata
• Piako
• New Plymouth
• Palmerston North
• Rodney
• Rotorua
• Stratford
• Western Bay of Plenty
• Westland
• Whangarei.

The Greens health spokeswoman, Sue Kedgley said:

“To my knowledge New Zealand is the only country in the world that sprays Endosulfan on sports fields. Endosulfan can remain in the soil for up to six years and any skin, mouth or hand contact with the soil could cause harm,”

Endosulfan is a highly toxic insecticide which affects people’s hormonal system, and is linked to breast cancer, endometriosis, male breast enlargement and delayed sexual maturity. It can cause birth defects, and is linked to epilepsy, autism, cerebral palsy, lowered IQ, and Parkinson’s disease.

“The councils are using Endosulfan to kill earthworms. Worm casts allegedly cause balls to bounce and reduce the effectiveness of drainage under playing fields,” Ms Kedgley says.

“But there is absolutely no need for children to be put at risk by the use of this toxic chemical, when the problem can be safely treated by simply altering the ph of the soil with acidifying fertilisers, and creating an environment the earthworms don’t like. It is completely unnecessary – Auckland City Council stopped using Endosulfan in the mid 1990s as a result of community pressure and they have managed without it for more than a decade.”

The Green Party is calling for an end to the use of Endosulfan in New Zealand as part of its toxics policy, released today."

Wikipedia description of Endosulfan

"A neurotoxic organochlorine insecticide of the cyclodiene family of pesticides. It is an endocrine disruptor, and it is highly acutely toxic. It is banned in the European Union, Cambodia, and several other countries, while its use is restricted in other countries, including the Philippines (where it will be banned after September 2008).

It is still used extensively in many countries including India, New Zealand and the United States.

It is made by Bayer CropScience, Makhteshim-Agan, and Hindustan Insecticides Limited among others, and sold under the tradenames Thionex, Thiodan, Phaser, and Benzoepin. Because of its high toxicity and high potential for bioaccumulation and environmental contamination, a global ban on the use and manufacture of endosulfan is being considered under the Stockholm Convention.........

Endosulfan is one of the more toxic pesticides on the market today, responsible for many fatal pesticide poisoning incidents around the world. Endosulfan is also a xenoestrogen—a synthetic substance that imitates or enhances the effect of estrogens—and it can act as an endocrine disruptor, causing reproductive and developmental damage in both animals and humans. Whether endosulfan can cause cancer is debated."

Symptoms of Endosulfin poisoning include

• Hypersensitivity to stimulation
• Sensation of prickling, tingling or creeping on skin.
• Headache, dizziness, nausea, vomiting, in-coordination, tremor, mental confusion, hyper- excitable state.
• In severe cases: convulsions, seizures, coma and respiratory depression.

Farm workers are often exposed to Endosulfan during the course of their work.

Air monitoring studies have been carried out that demonstrate that people living, working, and going to school near fields where it is used can be exposed by breathing contaminated air. Endosulfan can also be absorbed through the skin.

1080

source: Stop 1080 Poison

"One of the prized polo-cross/rodeo & pony club horses recently killed at Rangipo, (along with 20 sheep) by 1080 poison baits broadcast in an "accidental overfly." The nearby prison water supply was also poisoned in the same operation, which was carried out by EPRO LTD, contracted by Environment Waikato (Waikato Regional Council) on behalf of AHB (Animal Health Board) and sanctioned by the NZ Environmental Risk Management Authority (ERMA).

The land treated could easily have been treated for possum control by safer alternative methods, ie. trapping and ferratox in bait stations, as it is NOT REMOTE, NOT INNACCESSIBLE, and NOT RUGGED TERRAIN.
It is obvious from the position of the animal, the damage to its leg, the vomited lungs and the distended veins, that this animal died a horrible and cruel death. Deer have been observed to have tried to rip open their own bellies in their agony, and have inflicted similar and worse damage to their bodies while under the effects of 1080. Dogs are driven insane by the excruciating pain inflicted upon them before succombing to a cruel death. Poisoned possums can travel several kms and may take up to 18 hours to die."

What is 1080?

source: Wikipedia

"Sodium fluoroacetate (also known as sodium monofluoroacetate, compound 1080 or 1080) is a potent metabolic poison that occurs naturally as an anti-herbivore metabolite in various plants. It works by interfering with the citric acid cycle, and is used primarily to control mammalian pests, including invasive species. The existence of this chemical was first noted in the Second World War.

Sodium fluoroacetate is used as a rodenticide. Farmers and graziers use the poison to protect pastures and crops from various herbivorous mammals. It is used in New Zealand to control the Common Brushtail Possum , while in the United States it is used to kill coyotes. Other countries using 1080 include Australia, Mexico and Israel

Itis highly toxic to mammals and insects. The oral dose of fluoroacetate sufficient to be lethal in humans is 2–10 mg/kg.

Species have different susceptibility to sodium fluoroacetate due to metabolic differences. The New Zealand Food Authority established lethal doses for a number of species.Dogs, cats and pigs appear to be the species most susceptable to poisoning."
