The poisonings appear to be occurring due to emissions of fluoride from the Alcoa aluminum smelter at Portland and the Austral Bricks factory at Craigieburn, the state's first and second biggest emitters of fluoride dust, respectively. According to Bruce Dawson of the EPA, the toxic chemical is being absorbed by nearby plants that kangaroos and other animals forage on. The animals may also be breathing in the chemical directly.
The levels of fluoride being emitted by Alcoa and Austral are fully legal under Australian law. The smelter emits 120 tons of the dust per year, while the factory emits 66 tons.
Some of the oil would undoubtedly wind up as the petrochemical based fertilizers and pesticides which are creating the dead zones in the Gulf when they are washed off of agricultural land. Also contributing to this killing of the oceans is all of the oil based cleaners, solvents and other products that we send down our drains.
Naturally a good proportion would go into the plastics that are so ubiquitous in our lives. Many of those wind up dumped into the oceans where they kill wildlife and form the huge garbage patches at the centre of the circulation gyres (the North Pacific patch is larger than Texas).
Some would help power the industrialized fishing that is destroying the worlds oceans. There is some evidence that the collapse of all fisheries could come in as little as three or four decades . Most of the oil would be burned for power, thereby producing more of the CO2 that is acidifying (i.e., killing) the oceans.

Mark Woodward of Daphne, Ala., looks for tar balls as he walks along the beach at dawn in Destin, Fla., Saturday, June 26. Oil from the Deepwater Horizon spill has started coming ashore in Destin and other beaches on the Florida and Alabama coasts.
Those cards, says Mr. Greve, could become critical in coming weeks and months. In the case of a hurricane hitting the 250-mile wide slick and pushing it over sand dunes and into beach towns, residents fear they'll face not only mass evacuations, but potential permanent relocation.
Oil from a BP spill in the Gulf of Mexico washed ashore at one of the largest tourist beaches in Mississippi on Monday, forcing tourists to pack their bags and evacuate the shore.
Sludgy brown oil, light sheen and tar balls arrived at a series of points in small towns in the Gulf state on Sunday, the first time oil has hit Mississippi's mainland. On Monday, it reached Biloxi, a major resort city famous for its casinos.
One day after state and local officials complained vehemently about the slow pace of cleanup efforts, just three people from a private contracting company hired by BP were working on Biloxi's shore, putting tar balls into containers.
Some children on holiday in Biloxi stepped into tar balls before their parents whisked them away from the beach.
"We are leaving today. My child stepped in oil yesterday as we were playing on the beach. Obviously we are cutting our vacation short. This is a complete shame and very sad," said Susan Reed, who came with her family from Texas on vacation to Biloxi.
Ocean Springs, Mississippi/Toronto- Gluey gobs of thick oil from BP Plc's Gulf of Mexico spill washed ashore in Mississippi for the first time on Sunday as Russia called for a special levy on oil companies to finance a fund to help clean up environmental disasters like this one.
BP and the U.S. Coast Guard kept a close watch on tropical depression Alex as it moved into the southwestern gulf.
Forecasters expect Alex to make landfall again as a hurricane early on Thursday between Brownsville, Texas, and Tuxpan de Rodriguez Cano in Mexico, sparing BP's oil collection efforts at its ruptured deep-sea well.
Yet some environmentalists remain concerned about the secrecy surrounding the 840-acre, pork chop-shaped island off northeastern Long Island - and they're dubious of any claims that pollution has been remedied.
"We are highly concerned that when the government acts alone they may not be doing the best job," said Adrienne Esposito, executive director of the Citizens Campaign for the Environment. "Every government cleanup needs the public's involvement and independent oversight to ensure its validity."
The Department of Homeland Security is preparing to sell the island 100 miles east of Manhattan and build a new high-security laboratory in Kansas to study animal diseases.

The Q4000 multi-purpose oil field intervention vessel (L) and the drillship the Discoverer Explorer (C) burn off material from the Deepwater Horizon wellhead near the disaster site June 24, 2010.
For now, Tropical Storm Alex, which is hitting the western Caribbean with rain and high winds, is not expected to pass close to BP Plc.'s blown-out well off the Louisiana coast.
But even a miss that only generates large waves could greatly complicate clean-up efforts from Louisiana to Florida
Current official estimates suggest between 35,000 to 60,000 barrels a day are leaking from the rogue well. BP collected over 24,000 barrels on Friday and about 11,640 barrels in the first half of Saturday, the company estimated.
New equipment being moved to the site of the leak in the coming week could raise the daily collection rate to 53,000 barrels a day, U.S. Coast Guard Admiral Thad Allen, who is coordinating the U.S. oil spill response, said on Saturday.

A local resident navigates his boat in a flooded area in Luozhen Town of Fuzhou, Jiangxi province
Bulldozers dumped rocks and soil to repair a breach in the dykes hemming in the Fu River, in Jiangxi province, which forced over 100,000 people from their homes earlier this week.
More water may be on its way, as a flood crest passed through Xiang River in Hunan Province, making its way to the swollen Yangtze River.
"In some villages and counties along the Xiang River, farmlands and homes are flooded," Jiang Yongpeng, an official at the Hunan Environmental Protection Bureau, told Reuters.
Memphis Light, Gas and Water Division president Jerry Collins told The Commercial Appeal said the raccoon climbed more than 30 feet, over barriers intended to keep animals out, and short-circuited a switch on a substation.
Overall, about 8,000 customers were without city power late Thursday and early Friday.
The Pat Creek Fire, about 12 miles north of the Yukon River village, has exploded in size since it was detected late Friday afternoon. Fire information officer Sarah Saarloos said the blaze has "definitely grown a lot" since it was mapped at 325 acres on Saturday morning, although the size estimate hadn't been updated.
Gusty winds and dry fuels in the area contributed to the rapid growth, despite a heavy response by firefighters.
Less than 24 hours after it was reported, Saarloos said about 160 personnel were working on the fire, including 32 smokejumpers and five 20-person crews. An incident command center has been established in Stevens Village.
