Two of these “Soot Trackers” Are On Their Way to Downwinders…and You

Thanks to a grant from the Simmons Sisters Foundation, Downwinders is proud to announce we’ve purchased our first two portable Particulate Matter sensors for our No Safe Level Campaign against PM pollution.

They’ll be the only PM monitors of their kind in the region, and their arrival will inaugurate a new era in DFW citizen-empowered science.

The sensors are made by AEROQUAL, a New Zealand company, and you can’t find them on Amazon. They measure both PM 10 and PM 2.5 (microns) at the same time. Their sensor heads use laser and optical sensors to measure light scattered from particles passing through the laser beam. A built-in fan ensures a stable and precise flow of sample air to the sensor. They also compensate for humidity by way of an on-board humidity sensor.

Each comes with a long-life Lithium battery which allows for 24 hours of remote operation between charges. Recharging takes just 3 hours. The monitor can be plugged-in and left to run indefinitely. Besides displaying levels in real time, measurements can be stored on the device and downloaded later to a computer via the USB cable and bundled software.

They come factory-calibrated to European Union standards and are capable of being re-calibrated for side-by-side use with an EPA monitors, or any other local baseline.

These monitors have two parts – a base and a a detachable sensor head – making them even more useful. In the future Downwinders can buy other kinds of sensors from AEROQUAL to plug into the base and test for gaseous pollutants like Ozone, or Sulfur Dioxide. In all, 28 other sensors are available.

Before now you either had to buy $16,000 PM sensors that were fully calibrated or settle for much less reliable equipment. But the technology is moving so quickly and demand is scaling up so fast that a middle-income niche market for scientifically-rigorous instruments is beginning to provide opportunities to non-profit groups like Downwinders, and the public in general.

Along with these portable sensors, we’re also ordering stationary PM monitors as part of the regional network being established by UTD and others.

As a result of this influx of technology, Downwinders is creating a PM Project Science Director position to maintain the integrity of our research. The Science Director will be in charge of these monitors, training citizens on how to operate them, and overseeing their use in the field.

Our plans are to begin using the sensors in neighborhoods and suspected hot spots as soon as possible to help us fill out our PM Map of DFW. We want to be able to loan them out to those citizens who’ve gone through the training and have a problem they want to investigate. They’ll also be available for use during accidents, explosions, and fires.

We’re not letting state and EPA rollbacks stop us. We’re creating our own regional air monitoring network. Are you interested in joining? Stand by. We’re just getting started.

 

New Study Links PM Pollution to Depression and Suicide

Reviewing a decade of death statistics revealed a 16% increase in mortality risk on the first day of haze and a 27% increase on the second day compared to better air days.

If the haze was accompanied by high ozone pollution, the risk of death increased by 79%.

As shocking as this sounds, it aligns with other recent studies that have found a connection between short-term increases in air pollution and aberrant mental behavior. Significantly higher rates of Autism, Parkinson’s, ADHD and juvenile delinquency have all been linked to PM pollution, most at ambient levels assumed by regulators to be “safe.”

PM pollution has even been linked to low stock market performance in more than one study.

Researchers believe air pollution affects a person’s emotional state, making them more likely to feel depressed. They urge mental health professionals to be aware that bad air days are triggers for acute episodes.

PM pollution is so microscopically tiny it not only goes deep into your lungs, it actually can pass through your lung lining directly into your blood stream. Think about the places where your body uses a lot of blood – your heart and your brain. We’ve known PM causes heart attacks and strikes for some time. But research linking it to a wide variety of brain disorders is only fairly recent.

Authored by faculty at Hong Kong Polytechnic University, this most recent study examined more than 284,000 deaths, including those among people with mental and behavioral disorders including depression, bipolar, schizophrenia and dementia. It defined “haze days” as those on which pollutants gather in the air and cut visibility, usually dry days with low winds. In the study period from 2007 to 2014, there were 111 haze days when particle pollution was on average twice as high.

These findings are compatible with a recent Belgian study, which reported “[Short-term] increases in outdoor air pollutants such as particles or ozone can trigger suicide, particularly during warm periods, even at concentrations below the European thresholds.”

Unfortunately, we may have a local way to further prove this hypothesis. On October 19th of last year there was a still unexplained catastrophic air event that caused PM levels to go much more than twice a high as “normal,” accompanied by an increase in ozone pollution so severe it bumped the entire regional average by a part per billion. Could an examination of death certificates in Ellis, Dallas, Tarrant and Denton Counties reveal if this really “bad air day” caused a spike in North Texas suicides?

 

Downwinders at Risk’s “No Safe Level”  PM Pollution Campaign Committee has scheduled its next meeting for Saturday March 10th at the Meadows Center at 2900 Live Oak. 

An Italian Multinational is Using West Dallas to Import Toxic Cement into North Texas

And BuzziUnicemUSA wants the City’s permission to build a new 170-foot tall silo to store it in

 

Just when you thought you had a handle on the environmental hazards plaguing West Dallas, up pops another out of left field.

Lead, sure. Asbestos, check. Benzene too. Arsenic, yes.

But you might not expect rail cars and silos full of finely-grained toxic cement – cement made by burning hazardous waste as “fuel” in a cement plant. Cement that still has the residues of that hazardous waste inside it. Residues like lead, and arsenic and Dioxins – the stuff in Agent Orange.That was one of the unpleasant surprises during a February 1st on-site meeting between neighborhood activists and the folks who own and operate the Buzzi cement terminal on Lone Star Drive between Commerce and Singleton to discuss the construction of a huge new silo at the facility.

BuzziUnicemUSA is a  huge Italian-based multinational. In the US, the Company operates 7 cement manufacturing plants and 29 other distribution terminals in the United States besides the one in West Dallas.

On February 22nd, Buzzi is scheduled to come before the City of Dallas Board of Adjustment seeking a “height variance” that would allow it to build the new silo 17 stories tall – 60 feet further up than they can go now with current zoning restrictions.

With the exception of the abandoned but still-standing 1920’s garbage incinerator smokestack just a couple of blocks away on West Commerce, it would be the tallest structure in West Dallas.

The idea of yet another industrial eyesore in a neighborhood that has battled for over a century with such things was not well-received by the delegation of neighborhood residents. Nor was the news that the company didn’t have a Plan B for addressing their concerns.

But perhaps most surprising was the news that the company was importing cement from its hazardous waste burning kilns in Missouri and off-loading it in Dallas to be used in the construction boom here.

To know how offensive that might strike residents and local environmentalists, you have to know history. Lots and lots of history.

The Trinity Portland Cement Plant in West Dallas          1906-1984, Dallas Public Library

West Dallas was founded in part when a group of Galveston investors established the Trinity Portland Cement Company in 1906 and imported an entire Mexican village to build and run their cement kiln.

“Cement City” was established a couple of miles west of the then-Dallas city limits, and existed on the books up into the 1960’s. This was part of the White Establishment pattern of keeping those deemed “undesirable” – polluters and people – segregated from Dallas proper. Many West Dallas families can trace their beginnings in this country to these first cement plant workers.

Even after a growing Dallas swallowed Cement City, the West Dallas cement plant remained. In 1984, its owners announced plans to begin burning hazardous waste instead of oil or gas as a “fuel” for making its product.

But 1984 happened to be the year West Dallas residents’ fight against wholesale lead contamination from the RSR smelter was reaching its climax. They were forcing a complete closure (a complete clean-up would take much longer), and were in no mood to battle another source of toxic pollution.

At that time, the community was represented in Congress by U.S. Representative Martin Frost, a mid-cities Democrat. He was able to draft and successfully pass what became known as “The Frost Amendment” which prohibited the burning of hazardous waste in cement kilns located in any U.S. city with 500,000 or more residents. Welding the law’s language as carefully as a surgeon’s knife, Dallas was the only city affected.

Without the prospect of becoming a hazardous waste incinerator and being able to charge for waste “fuel” instead of having to pay for gas or coal, the West Dallas cement plant closed shortly after Frost’s amendment was passed.

Two years later the idea would surface again in near-by Midlothian, the self-proclaimed “Cement Capitol of Texas” with three cement plants and only three thousand residents. This is Downwinders at Risk’s creation story. We’re here because of those Midlothian waste-burning cement plants and the multi-decade campaign citizens fought to end it.

Part of that ending was the successful  “Green Cement Campaign” which persuaded local governments to quit buying and using the cement from the dirtier waste-burners in favor of those cement plants using conventional fuels. Dallas was the first of a dozen cities and counties to pass a Green Cement procurement ordinance. Fort Worth, Plano, and Arlington passed similar ordinances. They were the reason why TXI decided to stop burning hazardous waste in 2008. For the first time in over 20 years, no toxic cement was being made or used in North Texas. Most locals probably thought they would never have to deal with the subject again.

Which makes the news of Buzzi’s importing of cement from Missouri waste-burning kilns very disappointing indeed. Apparently the company is shipping tons and tons of the stuff into Dallas for Ready-Mix to use in a host of construction projects, including many in Frisco. It’s quite possible the the new Cowboys facility there is being built with cement containing the residues of hazardous wastes, including lead.

The RSR lead smelter in Dallas, 1981

And that’s problematic because much like West Dallas, Frisco has had a long toxic dance with lead. The ancient and dilapidated Exide lead smelter was shut down in 2012 because it was violating lead air pollution standards. It’s not operating now, but the land the smelter owned is still severely contaminated and at the center of a bitter legal battle between the City and Exide. How ironic is it for Frisco to have recently rid itself of a lead smelter only to have lead waste imported into the city and disposed of under the guise of cement?

How ironic to have Dallas and Plano help stop the manufacture and use of local toxic cement, only to provide a commercial market for Missouri’s?

And for West Dallas to get rid of one of the its first environmental injustices, stop the original waste-burning wanna-be in its tracks, and still find itself a major depot for toxic cement?

Residents who want to see West Dallas continue to overcome and redress its racist past should be at the Board of Adjustment hearing at City Hall on the 22nd. Call Trena  Law @ (214)670-4206 to get details about time and speaking opportunities. Stay tuned.
