James Fallows at the Atlantic has been covering the ongoing terrible pollution problems in China. I think of Kevin Drum’s discussion of lead and crime, and wonder if the high-crime American past is the Chinese future.
In Fallows’ recent post on China’s Pollution: the Birth Defect Angle he wrote:
I don’t personally know whether heavy-metal and other pollutant burdens in China are in fact causing birth defects and cognitive disorders. I’m not in a position to judge the scientific literature. But I do know that the pollution level in China is terrible; that (even) the Chinese press is sounding the warning about the effects; and that in other parts of the world toxins have of course been shown to cause physical and mental defects and diseases. This is a very big problem in China, perhaps even bigger than people there yet know.
He quotes a reader who points out:
While any country with a population as large as China’s will have some number of children born with birth defects, there are persistent rumors that the horrendous pollution in China has led to a huge increase such births in China. This, combined with the one-child policy, has led to orphanages being filled with special needs children, some of whom have very complex and difficult medical needs. In addition, children remaining in families often have less obvious medical issues that affect their ability to live full lives.
[I wonder what] effect that this is going to have on China as it continues to develop….
I lived in [a former Soviet bloc country] in the early 90s. Environmental degradation was a huge issue, and one that everyone I met, whatever their politics, agreed had contributed to the collapse of the communist system. I bet the party officials in Beijing know that very well.
Another reader says:
One must wonder, in addition to mild retardation, what other personality disorders can result from this disruption in normal development of the brain, from birth onward. Are they building a society where certain psychological disorders are the norm? Are we seeing this mass disorder and mis-diagnosing it as just the modern Chinese culture? [emphasis added]
Kevin Drum argues that, in the US at least, we *have* mis-diagnosed lead poisoning as culture:
[M]urder rates have always been higher in big cities than in towns and small cities. We’re so used to this that it seems unsurprising, but [lead researcher Rick] Nevin points out that it might actually have a surprising explanation—because big cities have lots of cars in a small area, they also had high densities of atmospheric lead during the postwar era. But as lead levels in gasoline decreased, the differences between big and small cities largely went away. And guess what? The difference in murder rates went away too. Today, homicide rates are similar in cities of all sizes. It may be that violent crime isn’t an inevitable consequence of being a big city after all.
The evidence Drum presents says that Fallow’s second reader is wrong about one thing. What we see in China and its culture *today* doesn’t reflect modern pollution problems. There’s about a 25-year lag between lead exposure and social problems, because exposed children have to grow up. An increasingly crime-ridden and violent Chinese society is a couple of decades away — which should be a frightening prospect for everyone, not just the Chinese.
One might equally speculate that, since most crimes (particularly violent crimes) are committed by single young men, there is a different cause for current Chinese crime problems. As a result of the single child policy, there was a fair amount of female infanticide — driven by the cultural demand for a male heir for the family. As a result, there are not enough young women to go around.
Add the fact that young Chinese women today have options that don’t include getting married (and, inevidably, becoming a semi-slave to their mother-in-law). What youget is an exceptionally large percentage of the young male population which is unmarried . . . and has no real prospect of ever getting married and establishing a family. Presto! Rising crime rates.
No doubt that is overly simplistic in some respects. But it does suggest something worth a hard look by Chinese policy makers.
On paper China has about the toughest regulations on heavy metals in the world, in the case of mercury they are far stricter than in the EU. But in reality they are about as real as the extensive bills of rights in Eastern Bloc constitutions. And let’s nod kid ourselves, it’s the industry’s wet dream (at least in the US) to be able to legally pollute as much as the Chinese in reality do.
I certainly hope that China solves its environmental and social problems. What we can do to move that along is to keep working on building sustainable alternatives to polluting fuels.
it’s the industry’s wet dream (at least in the US) to be able to legally pollute as much as the Chinese in reality do.
The people who want to pollute do so – in China. They don’t do it in the U.S., and are happy not to, because they want their own kids to breathe clean air and see blue skies.
It’s my guess that there are plenty of people who realize that when the “playing field” is leveled, and there is no economic benefit to pollution, it’s better not to pollute. That’s why a strong regulatory environment (one that’s enforced globally, through treaties) benefits everyone. I imagine (again – just a guess) that even polluters realize that in a perfect world, pollution would be regulated. They just don’t want to be held to those standards before their competitors are.
@sapient: They just don’t want to be held to those standards before their competitors are.
What they really want is to have their competitors held to those standards but be able to violate them themselves. That way they get a reasonably clean environment and a competitive advantage. That’s why you still have problems with violations even when the regulations are reasonably even across a whole industry.
Pollution prevention is expensive. It’s cheaper to have the chief lobbyist of the lead industry get a leading position at EPA. The experts proposed tighthening the maximmum allowable value by a factor of 4, he crushed that and proposed loosening it by a factor of 40 instead since there was (according to him) no indication that lead was in any way dangerous or detrimental to health. Fortunately that was a bit too much even in the Bush/Cheney era to swallow.
For lead exposure throughout the population, the two main sources are: (a) white lead used in paint and (b) tetraethyl lead used as an antiknock in gasoline–the latter being especially bad because it dumps lead into the air. So the question is not pollution in China in general, but the extent to which those two compounds are used. Other uses (eg batteries) could produce exposure near the sites of mining and manufacturing, but not the kind of pervasive exposure that the first two will. Lead-glazed pottery or lead pipes, similarly, are a problem but one with limited exposure.
One of the first hits for a simple Google search for “leaded gasoline china” is this:
If that’s right, China is likely seeing an upswing in crime that will continue for the next few decades, and will then decline depending on lead inputs from other than gasoline.
The lead hypothesis is really interesting, and the point that it is not lead in China is well taken. Given that the link to violence is correlative, we really don’t know if other heavy metal poisoning would produce similar effects and the pollution in China is all the heavy metals, not just lead. However, since China is the biggest producer of refined lead, there are other routes for the population to be affected by lead in particular.
This article notes that a lot of these incidents are lead, though aluminum, mercury, cadmium, copper and antimony among others are in the mix.
Yellow sand is a problem here, though the consensus from most researchers is that the heavy metals drop out earlier. I hope…
