The 4 Worst Sources of Pollution of Lakes and Streams

May 18, 2013 in Pollution

Three fourths of the surface of the earth is water, but only a small percentage of that is not salt water. Human beings and animals need water to live but every year more and more water of that water is becoming so polluted it can not sustain life.

A great deal of that pollution is occurring in the third world, and in developing nations like China and India. However, in the United States and even in Minnesota, our lakes and streams are threatened by man-made pollution.

Independent Air Test at Mayflower Oil Spill Reveal 30 Toxic Chemicals at High Levels

April 30, 2013 in Pollution, Tar Sands

Health Symptoms Persist Despite Denials from Exxon and Agencies

Little Rock--A citizen based organization responding the recent Exxon Pegasus Pipeline rupture and tar sands oil spill discovered over twenty-five toxic chemicals in the first ambient air sample collected on March 30.

Community leader, April Lane, has been collecting health reports from residents since the pipeline rupture on March 29. Lane relayed that “even four weeks later, residents are still feeling symptoms from the chemical exposure. People have consistently talked about gastrointestinal problems, headaches, respiratory problems, skin irritation including chemical burns, and extreme fatigue.” These symptoms are consistent with exposure to the chemicals found in the independent air testing.

According to Dr. Neil Carman with the Lone Star Chapter of Sierra Club and former Texas Commission on Environmental Quality, “Thirty toxic hydrocarbons were measured above the detection limits. Each of the thirty hydrocarbons measured in the Mayflower release is a toxic chemical on its own and may pose a threat to human health depending on various exposure and individual factors. Total toxic hydrocarbons were detected at more than 88,000 parts per billion in the ambient air and present a complex airborne mixture or soup of toxic chemicals that residents may have been exposed to from the Mayflower tar sands bitumen spill.”

Response from Exxon, State & Local Officials

Lane is interviewing residents about their health effects and collecting air quality data because state agencies have not been proactive in informing residents of the possible health effects associated with this particular chemical mixture also known as Wabasca Heavy Crude oil. Wabasca Heavy Crude oil, as identified by Exxon, is heavy oil (bitumen) that is diluted with lighter hydrocarbons like Benzene to allow for easier flow through pipelines.

Lane is a student at the University of Central Arkansas and President of Environmental Alliance at UCA; she also works with the Faulkner County Citizens Advisory Group. FCCAG was trained last November by Global Community Monitor in Bucket Brigade air sampling techniques.

Lane’s initial air sample on March 30 detected over twenty-five toxic chemicals including cancer causing benzene and ethylbenzene. According to the Agency for Toxic Substances and Disease Registry, chemicals can have varying health effects depending on intensity and frequency of exposure. Short-term, high levels of exposure and long-term low level exposure to benzene and ethylbenzene have led to increased cancer rates. Many of the chemicals have developmental, neurological and reproductive health effects.

Chemical detected

Long term health effects

Short term health effects

Benzene

Cancer, possible reproductive and/or developmental effects

Breathing very high levels of benzene can result in death, while high levels can cause drowsiness, dizziness, rapid heart rate, headaches, tremors, confusion, and unconsciousness.

Ethylbenzene

Cancer and reproductive effects.

Exposure to high levels of ethylbenzene in air for short periods can cause eye and throat irritation. Exposure to higher levels can result in dizziness.

n-hexane

Damage to the nervous system, numbness in the extremities, muscular weakness, blurred vision, headache, and fatigue have been observed.

The only people known to have been affected by exposure to n-hexane use are at work. Breathing large amounts caused numbness in the feet and hands, followed by muscle weakness in the feet and lower legs. If removed from the exposure, the workers recovered in 6 months to a year.

Toluene

Breathing very high levels of toluene during pregnancy can result in children with birth defects and retard mental abilities, and growth. We do not know if toluene harms the unborn child if the mother is exposed to low levels of toluene during pregnancy.

Toluene may affect the nervous system. Low to moderate levels can cause tiredness, confusion, weakness, drunken-type actions, memory loss, nausea, loss of appetite, and hearing and color vision loss. These symptoms usually disappear when exposure is stopped. Inhaling High levels of toluene in a short time can make you feel light-headed, dizzy, or sleepy. It can also cause unconsciousness, and even death.

High levels of toluene may affect your kidneys.

Xylenes

Studies of unborn animals indicate that high concentrations of xylene may cause increased numbers of deaths, and delayed growth and development. In many instances, these same concentrations also cause damage to the mothers. We do not know if xylene harms the unborn child if the mother is exposed to low levels of xylene during pregnancy.

High levels of exposure for short or long periods can cause headaches, lack of muscle coordination, dizziness, confusion, and changes in one’s sense of balance. Exposure of people to high levels of xylene for short periods can also cause irritation of the skin, eyes, nose, and throat; difficulty in breathing; problems with the lungs; delayed reaction time; memory difficulties; stomach discomfort; and possibly changes in the liver and kidneys. It can cause unconsciousness and even death at very high levels.

Hazardous air pollutants or HAPs detected include seven hydrocarbons identified as benzene, toluene, ethylbenzene, m,p-xylenes, o-xylene, hexane, and cumene. HAPs are regulated under the 1990 Federal Clean Air Act amendments as the most toxic of all known airborne chemicals.

The Bucket Brigade uses a certified laboratory capable of detecting VOC’s in the low level part per billion range because residential health safety levels are set in parts per billion, not parts per million. Air testing in the parts per million range is approved for worker-only exposures and not residential exposures where vulnerable populations like children, pregnant women, seniors and sick people may live.

Benzene vapors in the Mayflower sample were measured at 220 parts per billion by volume (ppbV), exceeding the Texas short-term effects screening levels (ESL) for benzene of 54 parts per billion (ppb) by four times. Many residents were exposed for several days and are still being exposed to crude remaining in the environment.

Global Community Monitor Bucket Brigade Trainer Ruth Breech commented, “The spill and response has been a disservice to the community. People are obviously suffering and experiencing health symptoms from chemical exposure related to the oil spill. State and Federal need to step up immediately to document and prevent any further health issues associated with the Exxon oil spill. Agencies need to share information in a manner to ensure informed decision making and enable access to necessary resources such as medical treatment for chemical exposure.”

In addition to exposure to these chemicals associated with the Wabasca Heavy Crude oil spill, residents have many questions about the cleanup operations and long-term exposure to chemicals.

On April 22nd, FCCAG held a Town Hall Meeting to discuss issues related to the oil spill. The goal of the event was to make a prioritized list of recommended actions and time frame for completion. Several presentations were given by Board Members of FCCAG, including the results of the Bucket Brigade air testing. Experts in oil spill pollution Dr. Wilma Subra and Dr. Riki Ott also presented an analysis of the available air, water, and soil data that has been collected by Exxon, EPA, and the state. These experts relayed their first-hand experiences while working on the Exxon Valdez oil spill and the BP disaster in the Gulf.

Over 100 people attended the all-day event that was held at the Faulkner County Natural Resource Center. The list of recommended actions has been hand-delivered to the Mayflower City Planning Committee. FCCAG will continue to work with the people of Mayflower and state and local officials to ensure the health and safety of the communities and ecosystems that are affected by this disaster.

Keystone XL: Oil Sands Health Concerns Rise Downstream Of Expanding Extraction

April 27, 2013 in Pollution, Tar Sands

Raymond Ladouceur remembers when he could dip a cup into the Athabasca River for a drink. He remembers when the trout and muskrats were plentiful -- and when his community was healthy.

Despite recent heart surgery, Ladouceur, 72, still fishes and traps, as he has his whole life at Big Point in Fort Chipewyan, Alberta. He snared his first fox at age 6 and recalled waddling home with the animal around his neck, its body dragging between his legs.

But times have changed, said Ladouceur, an elder with the Métis Canadian aboriginal people.

"Now, you can't drink water from the river. It's too dangerous," Ladouceur told The Huffington Post, taking a break from chopping wood. "We're seeing deformed fish, which I'd never seen in my whole entire years. And something in that water is killing the muskrats."

Plastic Pollution: An Ocean Emergency

March 1, 2013 in Oceans, Pollution

The oceans have become one giant refuse bin for all manner of plastics. Environmental and health concerns associated with plastic pollution are a long recognised international problem (Carpenter & Smith 1972). Whilst approximately 10% of all solid waste is plastic (Heap 2009), up to 80% of the waste that accumulates on land, shorelines, the ocean surface, or seabed is plastic (Barnes et al. 2009).

Profit Before Safety: Engineer Exposes Coverup of Reactor Flaw

February 28, 2013 in Climate Change, Oceans, Pollution

Former Babcock-Hitachi engineer and member of the Japanese Parliament committee investigating TEPCO, Mitsuhiko Tanaka, details a flaw in the manufacture of the pressure vessel for Fukushima Daiichi reactor 4. This flaw was covered up despite compromising the safety of the reactor. Though not the cause of the explosion, it was one of many problems at the plant not properly investigated or adequately repaired.

Water Treatment Contaminants: Forgotten Toxics in American Water

February 27, 2013 in Climate Change, Pollution, Water

Water treatment plants along the East Coast are struggling to recover from Superstorm Sandy, whose torrential rains washed tens of millions of gallons of raw or partially treated sewage into waterways.

The less dramatic but equally urgent story: inside those waterworks, and others across the nation, chlorine, added as a disinfectant to kill diseasecausing microganisms in dirty source water, is reacting with rotting organic matter like sewage, manure from livestock, dead animals and fallen leaves to form toxic chemicals that are potentially harmful to people.

This unintended side effect of chlorinating water to meet federal drinking water regulations creates a family of chemicals known as trihalomethanes. The Environmental Protection Agency lumps them under the euphemism “disinfection byproducts” but we call them what they are: toxic trash.

The EPA regulates four members of the trihalomethane family, the best known of which is chloroform, once used as an anesthetic and, in pulp detective stories, to knock out victims. Today, the U.S. government classifies chloroform as a "probable" human carcinogen. California officials consider it a “known” carcinogen. Three other regulated trihalomethanes are bromodichloromethane, bromoform, and dibromochloromethane. Hundreds more types of toxic trash are unregulated.

Scientists suspect that trihalomethanes in drinking water may cause thousands of cases of bladder cancer every year. These chemicals have also been linked to colon and rectal cancer, birth defects, low birth weight and miscarriage (NHDES 2006).

China’s Bad Air Day

January 17, 2013 in Climate Change, Pollution

When the smog in Beijing gets bad or “crazy bad,” as the U.S. embassy once described the air in a tweet, one can scarcely see across the street. The city’s new skyscrapers disappear into the thick haze. During the day, you can usually make out the sun through the brothy skies, but even at midday, the sun is just a small white saucer, its rays obscured by dense and poisonous clouds. After a day walking through the city, a thin layer of grime covers the skin. Clothes smell like an airport smoking lounge. And that’s a normal bad air day.

On Saturday, the American embassy recorded a peak of 886 micrograms of PM2.5 particles per cubic meter in Beijing. These are the tiny, killer particles of pollution. For the same scale, the World Health Organization says under 25 micrograms per cubic meter is safe. But it’s not just Beijing. On Monday, in Zhejiang province south of Shanghai, 800 miles away, a factory was engulfed in flame, but the air pollution was so bad, for three hours no one noticed the smoke billowing out of the factory. This is less of a surprise considering that the air pollution in Beijing was reported by ABC News as being more concentrated than levels inside forest fires in the United States.

What’s most shocking is that Beijing or a town in Zhejiang province couldn't even crack China’s top 10 cities with the worst air pollution, much less take the foremost spot. According to the state-run China Central Television, that dubious honor went to Shijiazhuang in Hebei province in northeastern China, with eight consecutive days of severe pollution.

Clearly, pollution is one of China’s biggest hurdles if it is to continue the greatest economic expansion in history. Beijing’s reaction to its recent bad air days gives reasons to hope that the government is taking the problem seriously. But the real test lies ahead. To overcome its environmental issues, the new Chinese leadership will have to take on its state-owned companies.
