Identifying poison ivy

May 22, 2014

This may become a series.

Found a good infographic today, on how to identify poison ivy — the bane of every Boy Scout and Scouter west of the Mississippi, and east of the Mississippi, too.

Poison ivy leaves turn a beautiful scarlet in the fall.  This beauty prompted English ship captains dropping off colonists in New England to take the potted vines back to England.

It is my experience that, while everyone can become allergic and react to poison ivy, no one reacts on first serious exposure. If you’re in the woods, it’s good to know what this stuff is, and avoid it.

If you’re exposed, wash it off.  Wash your clothes with some sort of oxidant (oxygen bleach for colors, or chlorine bleach if you don’t care); I use a 3:1 solution, water to chlorine bleach, to shower with after serious exposure.  The active chemical, urushiol, remains active until it is reacted chemically or by ultraviolet light — and so a young Scout who gets some ivy sap under his fingernails can continue to spread the exposure everywhere he scratches, until his hands are really washed clean.

Study the poster, learn to identify the stuff.  There’s a lot more to say.


Passing the 200 post mark on Rachel Carson, DDT and Malaria

January 13, 2013

I’m running behind in listing some of the articles, but since Utah Rep. Rob Bishop first alerted me to the stupidity raging on Rachel Carson‘s reputation, DDT‘s dangers and malaria, Millard Fillmore’s Bathtub hosted more than 200 articles on the topics.

Overwhelmingly, the evidence is that Rachel Carson was right, DDT is still dangerous and needs to be banned, but malaria still declines, even with declining DDT use.

You can look at the list of 200 articles, in reverse chronological order, here.

Still no ban on DDT: Treaty monitors allow DDT use to continue

December 16, 2012

Real news on a topic like DDT takes a while to filter into the public sphere, especially with interest groups, lobbyists and Astro-Turf groups working hard to fuzz up the messages.

News from the DDT Expert Group of the Conference of the Parties to the Stockholm Convention was posted recently at the Stockholm Convention website — the meeting was held in early December in Geneva, Switzerland.

Stockholm Convention on Persistent Organic Pol...

In the stuffy talk of international relations, the Stockholm Convention in this case refers to a treaty put into effect in 2001, sometimes known as the Persistent Organic Pollutants Treaty (POPs).  Now with more than 152 signatory nations and 178 entities offering some sort of ratification (not the U.S., sadly), the treaty urges control of chemicals that do not quickly break down once released into the environment, and which often end up as pollutants.  In setting up the agreement, there was a list of a dozen particularly nasty chemicals branded the “Dirty Dozen” particularly targeted for control due to their perniciousness — DDT was one of that group.

DDT can still play a role in fighting some insect-carried diseases, like malaria.  Since the treaty was worked out through the UN’s health arm, the World Health Organization (WHO), it holds a special reservation for DDT, keeping DDT available for use to fight disease.   Six years ago WHO developed a group to monitor DDT specifically, looking at whether it is still needed or whether its special provisions should be dropped.  The DDT Expert Group meets every two years.

Here’s the press release on the most recent meeting:

Stockholm Convention continues to allow DDT use for disease vector control

Fourth meeting of the DDT Expert Group assesses continued need for DDT, 3–5 December 2012, Geneva

The Conference of the Parties to the Stockholm Convention, under the guidance of the World Health Organization (WHO), allows the use of the insecticide DDT in disease vector control to protect public health.

The Stockholm Convention lists dichlorodiphenyltrichloroethane, better known at DDT, in its Annex B to restrict its production and use except for Parties that have notified the Secretariat of their intention to produce and /or use it for disease vector control. With the goal of reducing and ultimately eliminating the use of DDT, the Convention requires that the Conference of the Parties shall encourage each Party using DDT to develop and implement an action plan as part of the implementation plan of its obligation of the Convention.

At its fifth meeting held in April 2011, the Conference of the Parties to the Convention concluded that “countries that are relying on DDT for disease vector control may need to continue such use until locally appropriate and cost-effective alternatives are available for a sustainable transition away from DDT.” It also decided to evaluate the continued need for DDT for disease vector control at the sixth meeting of the Conference of the Parties “with the objective of accelerating the identification and development of locally appropriate cost-effective and safe alternatives.”

The DDT Expert Group was established in 2006 by the Conference of the Parties. The Group is mandated to assess, every two years, in consultation with the World Health Organization, the available scientific, technical, environmental and economic information related to production and use of DDT for consideration by the Conference of the Parties to the Stockholm Convention in its evaluation of continued need for DDT for disease vector control.

The fourth meeting of the DDT Expert Group reviewed as part of this ongoing assessment:

  1. Insecticide resistance (DDT and alternatives)
  2. New alternative products, including the work of the Persistent Organic Pollutants Review Committee
  3. Transition from DDT in disease vector control
  4. Decision support tool for vector control.

The DDT expert group recognized that there is a continued need for DDT in specific settings for disease vector control where effective or safer alternatives are still lacking. It recommended that the use of DDT in Indoor Residual Spray should be limited only to the most appropriate situations based on operational feasibility, epidemiological impact of disease transmission, entomological data and insecticide resistance management. It also recommended that countries should undertake further research and implementation of non-chemical methods and strategies for disease vector control to supplement reduced reliance on DDT.

The findings of the DDT Expert Group’s will be presented at the sixth meeting of the Conference of the Parties, being held back-to-back with the meetings of the conferences of the parties to the Rotterdam and Basel conventions, from 28 April to 11 May 2013, in Geneva.

Nothing too exciting.  Environmentalists should note DDT is still available for use, where need is great.  Use should be carefully controlled.  Pro-DDT propagandists should note, but won’t, that there is no ban on DDT yet, and that DDT is still available to fight malaria, wherever health workers make a determination it can work.  If anyone is really paying attention, this is one more complete and total refutation of the DDT Ban Hoax.

Rachel Carson’s ghost expresses concern that there is not yet a safe substitute for DDT to fight malaria, but is gratified that disease fighters and serious scientists now follow the concepts of safe chemical use she urged in 1962.

Clean Water Act at 40

October 18, 2012

Today is the 40th anniversary of the Clean Water Act.

In this photo, an entry in the 2012 Rachel Carson Sense of Wonder Photography Contest, can you tell the answer to Ben  Franklin’s not-rhetorical question:  “Is this a rising, or setting sun?”

We’re in the home stretch for the 2012 elections.  Are your congressional representatives among those who have pledged to cut funding for enforcement of the Clean Water Act?  Are they among those who have pledged to kill EPA?

How would that affect beaches like the one pictured above, by Ramsay and Kyle?

Nancy Stoner wrote at an EPA blog:

I am proud to be at EPA in 2012 for the 40th anniversary of the Clean Water Act, the nation’s foremost law for protecting our most irreplaceable resource. I often think about how a generation ago, the American people faced health and environmental threats in their waters that are almost unimaginable today.

Municipal and household wastes flowed untreated into our rivers, lakes and streams. Harmful chemicals were poured into the water from factories, chemical manufacturers, power plants and other facilities. Two-thirds of waterways were unsafe for swimming or fishing. Polluters weren’t held responsible. We lacked the science, technology and funding to address the problems.

Then on October 18, 1972, the Clean Water Act became law.

In the 40 years since, the Clean Water Act has kept tens of billions of pounds of sewage, chemicals and trash out of our waterways. Urban waterways have gone from wastelands to centers of redevelopment and activity, and we have doubled the number of American waters that meet standards for swimming and fishing. We’ve developed incredible science and spurred countless innovations in technology.

But I realize that despite the progress, there is still much, much more work to be done. And there are many challenges to clean water.

Today one-third of America’s assessed waterways still don’t meet water quality standards. Our nation’s water infrastructure is in tremendous need of improvement – the American Society of Civil Engineers gave it a D-, the lowest grade given to any public infrastructure. The population will grow 55 percent from 2000 and 2050, which will put added strain on water resources. Nitrogen and phosphorus pollution is increasingly harming streams, rivers, lakes, bays and coastal waters. Climate change is predicted to bring warmer temperatures, sea level rise, stronger storms, more droughts and changes to water chemistry. And we face less conventional pollutants – so-called emerging contaminants – that we’ve only recently had the science to detect.

The absolute best path forward is partnership – among all levels of government, the private sector, non-profits and the public. It is only because of partnership that we made so much progress during the past 40 years, and it is partnership that will lead to more progress over the next 40 years.

Lastly, I want to thank everyone who has been part of protecting water and for working to ensure that this vital resource our families, communities and economy depends on is safeguarded for generations to come.

Doubt, about the science of tobacco consumption, DDT, and global warming

(Yes, there is a bias.  Several biases exist there simultaneously, actually, so we should say there are biases.  The most important for you to know about are the biases for good science and accuracy, especially historical accuracy.)

Texas’s Superfund cleanup sites, listed by county

September 21, 2012

I got a notice from the Texas Commission on Environmental Quality:

The Texas Superfund Registry has been published in the September 21, 2012 issue of the Texas Register.

64 of Texas’s 254 counties have Superfund sites, either state or federal; many of them have been cleaned up, but many are active.  My count shows 161 sites total for Texas.

You can go to the site and find the information in several different sorts — here is the list, by county, unedited, straight from TCEQ (Not sure why Parker County is listed differently).

Index of Superfund sites by county.

If a county does not appear on this list, it is because there is no state or federal Superfund site in that county. This index includes all sites—those where cleanup is complete as well as those for which cleanup or assessment is in progress.

On the county maps, a light blue star designates a federal Superfund site. A red star designates a state Superfund site.

Whooping cough epidemic in Wenatchee, Washington, makes case for vaccinations

June 19, 2012

Professor Matthew Hay ... assailed by the furi...

Professor Matthew Hay, the famous Scottish physician and public health champion, ” … assailed by the furies of typhoid, measles, influenza, whooping cough and scarlet fever,” the same furies that affect public health around the world, including Wenatchee, Washington  (Photo credit: Wikipedia)

Thinking about skipping the DPT shot for your kids?

Read this story out of the Wenatchee (Washington) World about what happens to a small town when a significant number of people do that, and one of the kids gets sick.

EAST WENATCHEE — With 31 cases of whooping cough reported in Chelan and Douglas counties, health officials are saying the disease has reached epidemic proportions.

“People should be taking action to prevent it from getting worse by getting their Tdap shots, especially those people who are around infants,” said Mary Small, director of community health and preparedness at the Chelan-Douglas Health District. “Infants are at highest risk for death and hospitalization.”

The shots are for tetanus, diphtheria and pertussis, which is also known as whooping cough.

At last report, in early May, the two counties had a total of 22 cases this year. In 2009, there were no cases of pertussis in the two counties; in 2010, there was one case; and in 2011, there were two cases and one probable case, Small said.

You say your town isn’t as isolated as Wenatchee, Alaska?  Then there are higher odds that some stray person with whooping cough will wander into your town.  Your town is not as small as Wenatchee?  Then the odds are higher that you’ve got enough uninoculated kids to make an epidemic spread quickly.

Vaccinate the kids, will you?  They don’t need whooping cough.
