Environmental Remediation to Address Childhood Lead Poisoning Epidemic due to Artisanal Gold Mining in Zamfara, Nigeria

Background: From 2010 through 2013, integrated health and environmental responses addressed an unprecedented epidemic lead poisoning in Zamfara State, northern Nigeria. Artisanal gold mining caused widespread contamination resulting in the deaths of > 400 children. Socioeconomic, logistic, and security challenges required remediation and medical protocols within the context of local resources, labor practices, and cultural traditions. Objectives: Our aim was to implement emergency environmental remediation to abate exposures to 17,000 lead poisoned villagers, to facilitate chelation treatment of children ≤ 5 years old, and to establish local technical capacity and lead health advocacy programs to prevent future disasters. Methods: U.S. hazardous waste removal protocols were modified to accommodate local agricultural practices. Remediation was conducted over 4 years in three phases, progressing from an emergency response by international personnel to comprehensive cleanup funded and accomplished by the Nigerian government. Results: More than 27,000 m3 of contaminated soils and mining waste were removed from 820 residences and ore processing areas in eight villages, largely by hand labor, and disposed in constructed landfills. Excavated areas were capped with clean soils (≤ 25 mg/kg lead), decreasing soil lead concentrations by 89%, and 2,349 children received chelation treatment. Pre-chelation geometric mean blood lead levels for children ≤ 5 years old decreased from 149 μg/dL to 15 μg/dL over the 4-year remedial program. Conclusions: The unprecedented outbreak and response demonstrate that, given sufficient political will and modest investment, the world’s most challenging environmental health crises can be addressed by adapting proven response protocols to the capabilities of host countries.

The Pragmatic Value of Legal Fictions

Using a jurisprudence grounded in pragmatist philosophy, this chapter proposes a reconceiving of the concept of legal fictions. By tradition, fictions are treated in legal theory as consciously false assertions. This is unfortunate, for it engulfs law in logical contradiction, marginalizes all fictions as metaphysically suspect regardless of social value, and compromises the integrity of law and judicial decision-making. I argue instead that legal fictions be understood as propositional legal truths—doctrines, rules, principles—asserted in conscious recognition that they are inconsistent in meaning or otherwise in semantic conflict with true propositional claims made outside (or elsewhere within) the law. If the conflict produces no damage outside law or within—i.e. no confusion, incoherence, or functional destabilization—and if the fiction works some efficiency or functional improvement within the system of law, then the fiction has value and utility. But to the extent a legal fiction wreaks intersystemic havoc—generates confusion or incoherence, frustrates ability to function—or does not work some genuine utility within law, it is not useful, but problematic. Harmless and workable legal fictions hold pragmatic value and are law-worthy, while problematic, pernicious fictions should be removed from the law.

Food contamination as a pathway for lead exposure in children during the 2010–2013 lead poisoning epidemic in Zamfara, Nigeria

In 2010, an estimated 400 to 500 children died of acute lead poisoning associated with artisanal gold mining in Zamfara, Nigeria. Processing of gold ores containing up to 10% lead within residential compounds put residents, especially children, at the highest risk. Principal routes of exposure were incidental ingestion and inhalation of contaminated soil and dusts. Several Nigerian and international health organizations collaborated to reduce lead exposures through environmental remediation and medical treatment. The contribution of contaminated food to total lead exposure was assessed during the environmental health response. Objectives of this investigation were to assess the influence of cultural/dietary habits on lead exposure pathways and estimate the contribution of contaminated food to childrens blood lead levels (BLLs). A survey of village dietary practices and staple food lead content was conducted to determine dietary composition, caloric intakes, and lead intake. Potential blood lead increments were estimated using bio-kinetic modeling techniques. Most dietary lead exposure was associated with contamination of staple cereal grains and legumes during post-harvest processing and preparation in contaminated homes. Average post-harvest and processed cereal grain lead levels were 0.32mg/kg and 0.85mg/kg dry weight, respectively. Age-specific food lead intake ranged from 7 to 78μg/day. Lead ingestion and absorption were likely aggravated by the dusty environment, fasting between meals, and nutritional deficiencies. Contamination of staple cereal grains by highly bioavailable pulverized ores could account for as much as 11%-34% of childrens BLLs during the epidemic, and were a continuing source after residential soil remediation until stored grain inventories were exhausted.

Azdak, The Rascal Judge

Beware of willing Judges For Truth is a black cat In a windowless room at midnight And Justice a blind bat. A third and shrugging party Alone can right our wrong. This, this, this, Azdak Does for a mere song. Bertolt Brecht’s The Caucasian Chalk Circle introduces the character of Azdak—a corrupt, disrespectful menial clerk who on the heels of a coup d’etat finds himself appointed judge, complete with judicial robe and a wicker flask for a hat. The circumstances of his appointment foretell the irony of his tenure. A military coup spoils a sunny Easter Sunday in the Caucasian town of Grusinia. The governor is beheaded; the municipal judge hanged. Yet the Grand Duke, oppressive ruler of Grusinia and surrounding territories, escapes, due in no small part to unknowing protection afforded by Azdak. When Azdak learns the next day that the fugitive he harbored over night was the Grand Duke, he heads straight for the courthouse, raging at himself through the streets, to turn himself in and submit to punishment. No judge presides over the courtroom, however, only a few bored soldiers who find Azdak amusing though somewhat crazed. In their amusement they decide to make him the new judge, declaring that the old judge (still hanging in the corner) “was always a rascal. Now the rascal shall be the Judge” (72). On becoming judge, Azdak acts anything but honorably and respectfully toward the law. He sits on the statute book to give himself a more regal aire. He takes bribes; he derides and ridicules the parties appearing before him; he requires a female litigant to perform sexual acts; he does a preliminary assessment of the worth of each lawyer’s arguments by asking the amount of his fee. In short, Azdak judges arbitrarily, with bias and partiality. By play’s end, immediately following his final decrees, he flees out of concern for his life, never to be seen again.
