Soda = Fat

Byoliveridley

Sodat Fat

From The New York Department of Health

Try this experiment at home: Take two and a half cups of water, add 15-20 teaspoons of sugar and stir to dissolve. If you haven’t broken your wrist with all this action, take a sip or two, or gulp it down. No worries, you’ve just had all the nutrition in a typical soda!

That’s the message the NY Department of health is sending out with its new PR campaign against soda. Pretty gross and effective, I must say, though I would go one further and put it on every label of Coke, now wouldn’t that be nice!

Colonialism: Environmental Edition

Byoliveridley

Does put recycling in context…

Independent Online Edition > Environment

Regardless of how carefully you separate your waste, there is a good chance a disposal firm will dump it all in together with other kinds of plastic trash and ship it to the developing world to be dealt with by a family of migrant workers earning a pittance. They will deal with the salad-bar container, the pistachio ice-cream container and the superfluous bag for carrots in your shopping basket in a variety of different ways – it may be recycled, it may become landfill or it may simply be burnt. Whatever happens, it is generally not a priority for the waste disposal company. Britain dumps around two million tonnes of waste in China every year, everything from plastic mineral water bottles to shopping bags and other forms of superfluous packaging from some of the country’s biggest supermarkets.

Same for India as well. The article says that all of this “recycling” is illegal. But how do you hide 200,000 tonnes of plastic waste?

Read the whole article, it is tragic. Some highlights:

So too are the many and varied health complaints suffered by the local population, who risk multiple skin ailments and exposure to potent carcinogens as they touch the contaminated materials. Poisonous chemical effluents stream into their water supply, turning it black or lurid red, and studies by Greenpeace show that acid rain is the norm in this region. Children are prone to fevers and coughs. Their skin is often disfigured by the toxic plastic waste they have to process.

A report by the University of Shantou on the town of Guiyu, another Guangdong recycling hub, showed that more than 80 per cent of local children suffer from lead poisoning.

NC Smoking ban now inevitable?

Byoliveridley

Well, it has taken less than a decade (I am a pessimist), but looks like smoking in bars and restaurants may finally be over and done with in my old home state of NC.

Note that there is currently a HUGE loophole in the senate version of the bill, it permits smoking in “private clubs”. Many bars in NC designate themselves as “private clubs” to circumvent prohibition era (or thereabouts) laws that mandate liquor serving establishments to get a certain percentage of their revenue from food. So, my favourite Chapel Hill drinking establishment, The Dead Mule (no website, sorry!) is supposedly a “private club” – You supposedly pay a one time membership fee (usually less than 5 bucks), and are supposed to “sign in” any members and guests. This was all a farce anyway, and the Mule got extremely smoky, it was quite disgusting after a while.

One hopes that the final bill will make the ban universal. Bans like this work best when they don’t favour one group of establishments over the other for no real reason. The people who work at the Dead Mule are equally entitled to clean air.

1.5 cautious cheers, let’s see what happens in the end…

The state Senate voted Thursday to ban smoking in bars and restaurants in North Carolina. It set the stage for what would be a historic prohibition of a product that created thousands of jobs, built Duke and Wake Forest universities and has long been an integral part of the culture in the nation's top tobacco-producing state.

House members passed a tougher version last month, meaning that lawmakers will still have to work out a compromise, assuming the Senate passes the measure in a second vote on Monday. The bill passed Thursday by an eight-vote margin, 26-18, so that seems likely.

Hog Factories are Evil Part 1232

Byoliveridley

This rather interesting study tracks the movement and evolution of antibiotic resistance from hog cesspools (lagoons) caused by factory production (hog farming) of pig meat. You see, in order to pack that many hogs together and not cause them to keel over and die from disease, they have to be pumped full of antibiotics. Guess where the antibiotics end up? In their “refuse”.

As always, I leave you with The Meatrix if you want to know more about factory farming.

Antibiotic Resistance Tracked From Hog Farms to Groundwater

The routine use of antibiotics in swine production can have unintended consequences, with antibiotic resistance genes sometimes leaking from waste lagoons into groundwater, according to new research from the University of Illinois.

Researchers report that some genes found in hog waste lagoons are transferred, “like batons,” from one bacterial species to another. This migration across species and into new environments sometimes dilutes, and sometimes amplifies, genes conferring antibiotic resistance, they say.

The new report, in the August issue of “Applied and Environmental Microbiology,” tracks the passage of tetracycline resistance genes from hog waste lagoons into groundwater wells at two Illinois swine facilities.

Tetracycline is widely used in swine production. It is injected into the animals to treat or prevent disease, and is often used as an additive in hog feed to boost the animals’ growth.

Its near-continuous use in some hog farms promotes the evolution of tetracycline-resistant strains in the animals’ digestive tracts and manure.

This is the first study to take a broad sample of tetracycline resistance genes in a landscape dominated by hog farming, said principal investigator R.I. Mackie, a professor in the University of Illinois-Champaign department of animal sciences and an affiliate of the Institute for Genomic Biology.

Arsenic in the News

Byoliveridley

Professor wins $1M for arsenic filter – Yahoo! News

The National Academy of Engineering announced Thursday that the 2007 Grainger Challenge Prize for Sustainability would go to Abul Hussam, a chemistry professor at George Mason University in Fairfax. Hussam’s invention is already in use today, preventing serious health problems in residents of the professor’s native Bangladesh.

This British Geological Survey website provides a good primer to the problem. Some key points:

  1. Arsenic is very toxic
  2. Arsenic is naturally occurring in the shallow groundwater aquifers of Bengal and Bangladesh at a toxic level
  3. The surface water is contaminated with bacteria and was responsible for high infant mortality, so aid agencies in the ’70s encouraged the use of tube wells and other groundwater pumps. While this contributed to a decline in infant mortality from gastrointestinal infections, it also dosed unsuspecting people with disease causing levels of arsenic
  4. The technology for removal of arsenic is very well known. But most solutions require electricity/periodic maintenance/technical skills and are thus not universal or sustainable.
  5. Simplicity is the key. You can’t tell the people to not drink the water, it is the only clean water available. You can’t install water treatment plants, there is no running water, you can’t rely on solutions that are centralized.

So with all that in mind, here’s what Prof. Hussam did:

The Gold Award-winning SONO filter is a point-of-use method for removing arsenic from drinking water.  A top bucket is filled with locally available coarse river sand and a composite iron matrix (CIM).  The sand filters coarse particles and imparts mechanical stability, while the CIM removes inorganic arsenic.  The water then flows into a second bucket where it again filters through coarse river sand, then wood charcoal to remove organics, and finally through fine river sand and wet brick chips to remove fine particles and stabilize water flow.  The SONO filter is now manufactured and used in Bangladesh. That’s great, and easy!

That’s pretty much freshman chemistry right there, further proof that most innovation does not need new science, only people willing to spend some time on problems that don’t necessarily get looked at.

The real terrorist: Pollution

Byoliveridley

It is true. A staggering number of people die every year due to lack of access to clean water, air or food. Aggregate statistics like these are a good way to summarize the humongous nature of the problem. While reams and reams of coverage and attention are focused on “terrorists”, people all around the world die of much more mundane causes such as bacteria in water, smog, poverty, starvation, malnourishment, etc.

ScienceDaily: Pollution Causes 40 Percent Of Deaths Worldwide, Study Finds

About 40 percent of deaths worldwide are caused by water, air and soil pollution, concludes a Cornell researcher. Such environmental degradation, coupled with the growth in world population, are major causes behind the rapid increase in human diseases, which the World Health Organization has recently reported. Both factors contribute to the malnourishment and disease susceptibility of 3.7 billion people, he says.

Tennessee bans smoking in workplaces

Byoliveridley

North Carolina, you’re next, smoking bans finally make inroads in tobacco country.

Where Tobacco Ruled, Smoking Ban Gains Ground – New York Times

Tennessee will probably become the first major tobacco-growing state to pass a comprehensive smoke-free-workplace law. Gov. Phil Bredesen, a Democrat, proposed the ban in February. He also wants to triple taxes on cigarette sales and to use some of the money for smoking prevention.
