Coal Pollution Effects on Human Health

Coal fired power plants are the single largest source of pollution in any country. http://saferenvironment.wordpress.com/2008/09/05/coal-fired-power-plants-and-pollution/

Coal fired power plants are the single largest source of pollution in any country.

Coal-fired power plant emissions contribute to global warming, ozone smog, acid rain, regional haze, and – perhaps most consequential of all from a public health standpoint- fine particle pollution. Emissions from the U.S. power sector cause tens of thousands of premature deaths each year, and hundreds of thousands of heart attacks, asthma attacks, hospital admissions, and lost workdays. So why are these power plants still up and running, and more importantly, why are there still planned developments of new plants?

To simplify things, public health concerns have focused, for at least the last decade, on the role of very small airborne particles in causing or contributing to various forms of respiratory and cardiopulmonary ailments and increasing the risk of premature death. These fine particles are particularly dangerous because they can bypass your body’s defensive mechanisms and become lodged deep inside your lungs. In fact, research also indicates that short-term exposures to fine particle pollution is linked to cardiac effects, including increased risk of heart attack. Meanwhile, long-term exposure to fine particle pollution has been shown to increase the risk of death from cardiac and respiratory diseases and lung cancer, resulting in shorter life-expectancy for people living in the most polluted cities. So who are the people that are most likely to be exposed to these health risks? In general, the poor, minority groups, and people who live in the areas downwind of multiple power plants. And unfortunately, persistent elevated levels of fine particle pollution are common across wide areas of the U.S., mainly in the east.

The adverse effects, including abnormally high levels of mortality, occur even at low ambient concentrations of fine particles—suggesting there is no “safe” threshold for this type of pollution. Since most fine particle-related deaths are thought to occur within a year or two of exposure, reducing power plant pollution will have almost immediate benefits. Below is a very nice table that I found from Physicians for Social Responsibility, outlining various diseases/conditions connected to coal pollutants.

Coal Pollution vs human Health

As it stands, we are at a turning point for determining the U.S.’s future energy policies. The health consequences tied to coal production are vast and have major impacts. We need to address the issue of coal-fired energy production, and we need to address it now. There should be NO new construction of coal fired power plants, and we must initiate plans to retire as many coal plants as possible that are currently in production.

Finally, as a nation, we must develop our capacity to produce energy from clean, safe, renewable sources in order to phase out the existing coal plants without compromising the ability to meet the nations energy needs. Instead of investing any more of our money into coal, the U.S. should fund conservation measures, energy efficiency, and renewable energy sources such as wind energy and solar power, which don’t have such a negative effect on public health.

Wake Up and Stop Texas from Burning, Governor Perry

 Texas is in an unprecedented environmental emergency.

Eighty-one percent of the state is currently suffering exceptional drought.  It’s the worst one-year drought Texas has experienced in 116 years of state records. 

 Texas is literally on fire.  Over 3.6 million acres have burned in wildfires topping the record 1.8 million acres burned in 2010 with less than four months left.  There’ve been over 21,000 fires in Texas and wildfires in the state for 300 straight days. The Bastrop fire has been burning out of control for six days and nearly 1,400 homes have been destroyed 30 miles from the state capitol leaving Austin in clouds of toxic smoke. 

CLIMATE CHANGE Governor Perry has shown concern about the severe drought and wildfires.  Now it’s time for Perry to stop denying the root causes of climate change and take action to address those causes.

Climate change is caused by man-made greenhouse gas emissions.  Coal plants are the largest industrial source of carbon dioxide (CO2), the chief global warming gas.  Texas’ 19 coal-fired plants are the worst industrial cause of life-threatening, climate triggered perils that we are experiencing.  Texas coal-fired plants emit over 150 Million Tons of CO2 every year – over 99% of Texas coal plant air pollution — is currently unregulated.  Defended by Governor Perry, the Electric Reliability Council of Texas (ERCOT) and the Texas Public Utility Commission, the Texas coal plants are continuing to heat our atmosphere, fueling the drought conditions leading to wildfires and putting 24 million Texans in harm’s way.

Texans’ health and lives are at risk!  Governor Perry and his appointees who lead Texas state agencies must address the biggest root cause of climate change in our state – coal plant CO2 emissions.

 OZONE, TOO   Beside smoke from wildfires, 18 million Texans are breathing harmful ozone.  Ozone is caused when nitrogen oxide emissions from factories like coal plants mix with volatile organic compounds in sunlight creating ground-level smog.  According to the Texas Commission on Environmental Quality (TCEQ), Texans have suffered 56 bad air days in 2011 when the ozone levels were unsafe. 

 After cutting funds by 75% from the Texas Forest Service year, Governor Perry is now calling for help to fight wildfires from the same federal government that he attacked in law suits for trying to protect Americans air from unsafe coal plant pollution.  Perry enlisted the TCEQ, the Rail Road Commission, and the Texas PUC to fight new federal safeguards against both CO2 and ozone.

 By fighting federal safeguards against ozone, Governor Perry and state agency leaders are denying that serious problem too.  They need to wake up to the reality of our ozone problem and help, not hinder, efforts to clean up our air and cool the atmosphere.

 WHAT’S BAD FOR BUSINESS?  Perry, ERCOT – Texas’ electricity grid operator, and the PUC claims that Texas doesn’t have enough electricity sources in our state and that the better ozone standard would hurt business and cost jobs.  Yet, ERCOT’s own reports show that the grid was secure even when 5000 additional megawatts were forced off-line. 

 There are many non-polluting steps we can take to manage electricity demand more efficiently while generating lower pollution from Texas power plants.

 To Governor Perry, ERCOT, and PUC, we say: Wake up! 

 The price tag for drought and wildfire destruction is too high.  Losses to Texas’ agriculture alone were about $5.2 billion before the Labor Day weekend fires. We now face greater costs. Ignoring climate change and fighting, rather than supporting, clean energy solutions is costing Texans lives, homes, and jobs.

 FIRST RESPONDERS COMMITMENT  On the campaign trail, Governor Perry has repeatedly criticized public works programs like the New Deal, yet Texas firefighters fought to protect the beautiful cabins built by New Deal workers in Bastrop State Park this week.

 Perry, ERCOT, and the PUC need to respond like our brave fire fighters putting out the blazing wildfires across Texas.  The Governor and state leaders must recognize and extinguish the root cause of these problems – the massive burning of coal in coal-fired power plants in Texas.  There’s a safer, cleaner, cheaper way, Governor, and the stakes are too high to continue to allow the burning of dirty coal.

Texas Naughty Neighbors’ No-No.

Coal-fired plants create hazard across region, environmentalists say

Fayette Coal Plant

The report supports earlier concerns raised by Oklahoma officials about the potential impacts on their state from the nearly 30 coal-fired plants either operating, permitted or proposed in Texas.
