WHAT (& WHAT FOR): Lead is a metal often found in pipes, and in old paint (before it was banned in paint in the late 1970s). Before 1996, lead also found in vehicle fuel resulting in  soil contamination in many communities from both paint dust and vehicle pollution. 

HEALTH IMPACT: Lead is a neurotoxin and is known to have no safe blood lead level in children. 

Has been linked to:

1. Brain swelling, anemia, seizures, renal failure, reduced IQ, and ADHD

2. Damages brain development in children

3. Connected to behavioral problems like aggression and bullying, and internalizing problems such as depression and anxiety 

LOCAL IMPACT: Recent research in Santa Ana has shown that there is a disproportionately impact of solid lead contamination crisis on lower income, people of color communities. 

POSSIBLE RESPONSES: There are many ways to respond to lead contamination:

1. Providing special health care for children with high blood lead levels, and investigating possible sources of lead exposure in homes, daycares and school, playground, etc.

2. Implement strict housing policies where landlord and city housing officials are required to have lead inspections of homes for lead paint hazards (especially in low income, people of color communities)

3. Requiring a minimum reduction standard for lead paint in older homes 

4. Requiring blood lead level test as part of the routine check up for children (extremely important for children in low-income housing)

WHAT (& WHAT FOR): PFOAS are a group of large manufactured chemicals that are widely used in various everyday items. Often used in waterproof items and nonstick pans among other products.  They are used in a number of industrial processes. Improper disposal of the chemicals from industrial manufacturing has resulted in PFAS seeping down into the ground and into the water supply.  These chemicals are known to be forever chemicals that  do not degrade in the environment. 

HEALTH IMPACT: PFAS are known to be forever chemicals that cause weakened immune systems, increased cholesterol level, increased risk of testicular and kidney cancers, and decreased vaccine response in children. EPA has concluded that exposure to PFOA and PFOS over certain levels may result in developmental effects to fetuses during pregnancy (low birth weight) or breastfed infants (accelerated puberty, skeletal variations). 

LOCAL IMPACT: Both the State Water Board and the Santa Ana Water Board have initiated investigations. The PFAS investigation done by State of California Regional Water Quality Control Board reveals results that show PFAS concentrations above the current Notification Levels for drinking water. Santa Ana Water Board staff is currently working to identify potential sources of the contamination in the groundwater. 

POSSIBLE RESPONSES: 

1. Conduct wellhead treatment to treat PFAS impacted drinking water to levels below state-established PFOA/PFOS notification levels.

2.  Obtain a more comprehensive monitoring information on potential sources of PFAS

3. Set Effluent guidelines, develop analytical methods and issue water quality criteria for PFAS

We're still doing this Galileo schtick? Absolutely the worst model for the science-authority relationship, but scientists (well, at least physical scientists) still love it.  More to come...

First: Another list on another google doc and just looking at it https://docs.google.com/document/u/0/d/1UTQvW_OytC37IatMNR5qJK7qKfSylNpI2fT3pdteVZA/mobilebasic gets me started: we're all barely keeping up and just trying to direct the firehose into some readily available container like a google doc because we can't drink any more and it's the easiest thing to hand.  I'm happy with the dangerous "we": all we humanists and all them scientists are trying to do kaelidoscopics at speed, saving the excess for future analysis while trying to do the analysis right now and get something in print right now which is aleready too late.  "They" have better containers (infrastructure) and that matters, but I think it's important to note the shared space of urgency and excess and ask about the effects these have on analysis, ours and theirs and: ours.

It has to be hurried, the only take worth anything these days is the hot take, for scientists, science journalists, science analysts. An exaggeration, but I'm rushed. We know that air pollution (two words harboring such complexity and excess on its own: PM2.5, ozone, NOX, etc.etc.) impacts health in numerous ways, in and beyond our repiratory system; we know that those physiological logics are compounded by cultural logics, in their complexity and excess: race poverty geolocation healthcare access nutritional needs etc. etc. A kaleidoscopic intersectional analysis that, to get good reliable outcomes, takes time.

A need for generosity.

So as I make my way down the list in the google doc and read that some group or some lab shows the COVID-19 intersects with air pollution and makes for worse outcomes for African Americans I'm predisposed toward belief, for many good reasons, compounded by the rush. And the data and the correlations between, say, increased mortality in areas of northern Italy where there are higher levels of airpollution is certainly believable, compelling -- for NO2

and air pollution generally

https://www.sciencedirect.com/science/article/pii/S0269749120320601

That kind of crunching of large data sets seems believable -- and has been stamped as peer reviewed. So what do we do with this article in The Conversation

https://theconversation.com/air-pollution-covid-19-and-death-the-perils-of-bypassing-peer-review-136376

critical of a Harvard School of Public Health study available as a preprint on medrxiv --

https://www.medrxiv.org/content/10.1101/2020.04.05.20054502v2

-- that concludes that "an increase of only 1 μg/m3 in PM2.5 is associated with an 8% increase in the COVID-19 death rate (95% confidence interval [CI]: 2%, 15%)"?  The Canadian researchers in The Conversation are not convinced:

"It is almost impossible to try to adjust for the influence of all these factors, as this study tried to do, because the interactions between these variable are so complex. Accounting for these factors could only be done in studies using information from individual-level information."

"Proper peer review must not be bypassed — and the onus for respecting its role falls not just on journalists but also on scientists to communicate the correct information accurately."

I'm suspicious -- and if I had more time I would be more suspicious of my suspicions -- for two reasons: one, a lot of those studies on the google docs list are preprints.  But more importantly, the call for "individual-level information."  What does this mean? I don;t think anyone is working with "individual level information" in all of these studies, so why does this one become a target?

1. Because it's Harvard PH, of Six Cities study fame, first linking air pollution to increased mortality and the key reference point for US air pollution regulation. There's a long history of the oil industry and their scientists just trying to pick holes and cast doubt on these studies out of Harvard.

2. The criticism smacks of the most recent devious strategy of the air regulation opponents, which is to call for individiual level data in epidemiological to be released in the name of "transparency." Which can't be done.

So who are these Canadian guys and are they up to something more than "just raising questions and being good scientific skeptics"?

UPDATE 1 HOUR LATER:

So I looked them up: Mark Goldberg was a member of the Reanalysis Team of the Health Effects Institute that validated the Six Cities Study:

Unlikely, then, that he is some undustry beard...

ENVOI

p.232: "In these pages, I have repeatedly emphasized the complicity between subject and object of investigation. My role in this essay, as subject of investigation, has been entirely parasitical, since my only object has been the Subaltern Studies themselves. Yet I am part of their object as well. Situated within the current academic theater of cultural imperialism, with a certain carte d'entree into the elite theoretical ateliers in France, I bring news of power lines within the palace. Nothing can function without us, yet the part is at least historically ironic. What of the poststructuralist suggestion that all work is parasitical, slightly to the side of that which one wishes adequately to cover, that critic (historian) and text (subaltern) are always "beside themselves"? The chain of complicity does not halt at the closure of an essay."

p217: "[Subaltern Studies] can never be continuous with the subaltern's situational and uneven entry into political (not merely disciplinary, as in the case of the collective) hegemony as the content of an afterthe- fact description. This is the always asymmetrical relationship between the interpretation and transformation of the world which Marx marks in the eleventh thesis on Feuerbach. There the contrast is between the words haben interpretiert (present participle—a completed action—of interpretieren— the Romance verb which emphasizes the establishment of a meaning that is commensurate with a phenomenon through the metaphor of the fair exchange of prices) and zu verandern (infinitive—always open to the future—of the German verb which "means" strictly speaking, "to make other"). The latter expression matches haben interpretiert neither in its Latinate philosophical weight nor in its signification of propriety and completion, as transformierien would have done. Although not an unusual word, it is not the most common word for "change" in German—verwandeln. In the open-ended "making-other"—Veranderung—of the properly self-identical—adequately interpretiert—lies an allegory of the theorist's relationship to his subject-matter."
