Lead from toys not the real problem

Here’s what happens when you make a long verbal rant to someone about how the risk of lead exposure from water and air probably exceeds the risk from toys with lead paint, and then don’t blog about it because that means doing an hour or two of research and you don’t find the time… Someone else has the same notion, and actually writes about it AND gets published in a mainstream website!

The lingering danger to children from lead. – By Darshak Sanghavi – Slate Magazine

While tainted toys are in the news now, kids historically have gotten lead from two sources: the atmosphere and house paint. Roughly a quarter-million tons of lead compounds entered the atmosphere annually beginning in 1922, after a General Motors scientist developed a lead-based gasoline additive that prevented auto knocking. Lead’s chemical durability, recognized centuries ago, also made it an attractive paint additive. Toddlers are particularly susceptible to eating lead paint because it has a sugary taste; ancient Romans used lead powder to sweeten wine. By 1980, more than half a million American children—4 percent of all toddlers—had quite toxic blood lead levels from these sources.

Lead is a serious problem in the US, and the bulk of exposure is from crumbling infrastructure, the inability (or unwillingness) to fix and replace decaying lead pipes, and the still ubiquitous presence of lead paint layers in older houses.

The article doesn’t still give you exposure comparisons or numbers, so I guess I still have to do the work.

    California’s Prop 65 on Deathbed

    House votes to dump state food safety laws

    See this post for some context.

    The vote Wednesday was a sign of the tremendous power of the food industry in Congress. Corporations and trade groups that joined the National Uniformity for Food Coalition, which backed the bill, have contributed more than $3 million to members in the 2005-06 election cycle and $31 million since 1998, according to data from the Center for Responsive Politics.

    The industry also has many top lobbyists pushing the bill, including White House Chief of Staff Andrew Card’s brother, Brad Card, who represents the Food Products Association.

    Well, will it die in the senate? One wonders.

    Why bother with an elected goverment if all it does is pass bills written by big industry? Maybe it’s time to get the middlemen out and have big business actually run the country, maybe GM can take a shot! Or maybe the top guy on the Forbes list for the year can take over as president for the year, this will give Warren Buffett good incentive to knock off Mr Gates.

    Arsenic a rising risk?

    This is new information? Tell that to the millions of Bangladeshis and Indians suffering from Arsenic for many years now.

    As groundwater use increases due to population pressure and overexploitation of freshwater, expect this problem to get worse.

    Arsenic in Drinking Water Said to Be Rising Risk – New York Times

    Naturally occurring arsenic in drinking water poses a growing global health risk as large numbers of people unknowingly consume unsafe levels, researchers said on Wednesday.

    The problem is bigger than scientists had thought, and it affects nearly 140 million people in more than 70 countries, according to new research presented at the annual Royal Geographical Society meeting in London.

  • Arnold Schwarzenegger and Jodi Rell – Lead or Step Aside, EPA – washingtonpost.com

    The gubernator (and the Rellegator?? We need a nickname for her!) do not mince words in expressing their displeasure at the federal government putting roadblocks on state efforts to combat climate change.

    Arnold
    Schwarzenegger and Jodi Rell – Lead or Step Aside, EPA – washingtonpost.com

    It’s bad enough that the federal government has yet to take the threat of global warming seriously, but it borders on malfeasance for it to block the efforts of states such as California and Connecticut that are trying to protect the public’s health and welfare.

    California, Connecticut and 10 other states are poised to enact tailpipe emissions standards — tougher than existing federal requirements — that would cut greenhouse gas emissions from cars, light trucks and sport-utility vehicles by 392 million metric tons by the year 2020, the equivalent to taking 74 million of today’s cars off the road for an entire year.

    Yet for the past 16 months, the Environmental Protection Agency has refused to give us permission to do so.

    Even after the Supreme Court ruled in our favor last month, the federal government continues to stand in our way.

    Another discouraging sign came just last week, when President Bush issued an executive order to give federal agencies until the end of 2008 to continue studying the threat of greenhouse gas emissions and determine what can be done about them.

    To us, that again sounds like more of the same inaction and denial, and it is unconscionable.

    Well, the OP-ED says everything that needs to be said. The emperor pretends to forget that even market-based policies (the emperor’s preference) to mitigate climate change need rules, and rules for global warming, which is a global problem, are better off set at the global level. If we cannot get a worldwide agreement together, at least a country wide effort. The emperor has repeated over and over again that he will not pass any regulation in the recent future. So, at least the states are trying, see RGGI for the NorthEast and the West coast. Of course, the emperor is delaying, and denying all he can, yes, it is his responsibility, he is the decider, his administration does what he tells them to do, so there’s no sense in putting anything less than full responsibility on his shoulder.

    California, Connecticut and a host of like-minded states are proving that you can protect the environment and the economy simultaneously.

    It’s high time the federal government becomes our partner or gets out of the way.

    Well said, gubernator, and rellegator!

  • Majora Carter talks about Environmental Justice

    [googlevideo=http://video.google.com/videoplay?docid=2883494385256707942]

    Who is Majora Carter?

    Majora Carter is a visionary voice in city planning who views urban renewal through an environmental lens. The South Bronx native draws a direct connection between ecological, economic and social degradation. Hence her motto: “Green the ghetto!”

    With her inspired ideas and fierce persistence, Carter managed to bring the South Bronx its first open-waterfront park in 60 years, Hunts Point Riverside Park. Then she scored $1.25 million in federal funds for a greenway along the South Bronx waterfront, bringing the neighborhood open space, pedestrian and bike paths, and space for mixed-use economic development.

    h/t the grist for bringing this incredibly powerful video to my attention.

    The EJNet site is a great place to start if you want more information about Environmental Justice.

  • PCBs love to sorb to oil

    News of possible interest only to me. It seems obvious that oil present in sediment enhances sorption and storage of PCBs than soot/black carbon. After all, it is a liquid phase and is present in higher amounts than black carbon. PCBs are so hydrophobic that almost any organic material has a higher affinity for PCBs than water/sediment. Carbon is a strong PCB adsorbent only for planar PCBs, and then only if it is itself graphitic, hence planar. In all other cases, oil should outcompete  carbon for PCBs. Glad they found experimental evidence. In all my (three) years of analyzing for PCBs, the oily samples are always the highest concentration ones.

    Received for review January 18, 2006

    Revised manuscript received April 10, 2006

    Accepted April 11, 2006

    Abstract:

    The often-observed enhanced sorption of hydrophobic organic chemicals (HOCs) to sediments is frequently attributed to the presence of soot and soot-like materials. However, sediments may contain other hydrophobic phases, such as weathered oil residues. Previous experiments have shown that these residues can be efficient sorbents for certain PAHs. In this study we investigated sorption of PCBs to sediments contaminated with different concentrations and types of oils, and from that derived oil-water distribution coefficients (Koil). Sorption of PCBs to both fresh and weathered oils was proportional to sorbate hydrophobicity, and no effects of PCB planarity were observed. Furthermore, the experiments demonstrated that different oils sorbed PCBs similarly and extensively (Koil up to 108.3 for PCB 169), and that weathering caused an almost 2-fold increase in sorption of the lower chlorinated PCBs. Koil values indicated that at the PCB equilibrium concentrations tested (pg-ng/L range), for many congeners weathered oil is a stronger sorbent than pure soot and soot-like materials. Due to attenuation of adsorption to the latter materials in sediments (caused by competitive adsorption with organic matter), sedimentary weathered oil will therefore, if present as a separate phase, defeat sedimentary soot, coal, and charcoal as PCB sorbent in most cases. Consequently, weathered oil probably is the ultimate sedimentary sorbent for PCBs and should be included in HOC fate models.

  • Salmon linked to Larry Craig's downfall!

    Well, if you believe that correlation = causation, that is! But jokes aside, every time an anti-environmental icon goes down, the salmon rejoice. Not that I know much about fisheries, but salmon and Larry Craig, that’s a great combination right there!

    Sen. Craig’s fall may benefit salmon – Yahoo! News

    The surprising fall of Sen. Larry Craig, R-Idaho, removes a longtime obstacle to efforts by Democrats and environmentalists to promote salmon recovery on Northwest rivers.
    Craig, who was removed from leadership posts on the Senate Appropriations and Energy committees after a sex scandal, is known as one the most powerful voices in Congress on behalf of the timber and power industries. Environmentalists have fought him for years on issues from endangered salmon to public land grazing.

    At issue is the protection of salmon migration trails in Western rivers full of dams. The Bush administration in 2005, among other things, issued a salmon recovery plan that, among other things, counted farmed salmon in claiming that salmon populations were recovering (can’t even be bothered to argue against that!). Craig’s fall will let Harry Reid (Nevada) and Maria Cantwell (Washington) spearhead more sensible legislation.
