EDF_org - Perchlorate in food. Perchlorate is one of approximately 10,000 chemicals allowed for use in food and food packaging – and it’s also an ingredient in rocket fuel.
The Food and Drug Administration (FDA) approved perchlorate for use in plastic packaging and food handling equipment for dry food – like cereal, flour, spices, and many other additives – to reduce the buildup of static charges. Unfortunately, the chemical can migrate from plastic into our food. Perchlorate can also get into food when hypochlorite bleach (used as a disinfectant in food processing and to peel and to wash produce) is not managed carefully and allowed to degrade.

Executive Summary Since the mid-1990s, there has been an increasing amount of research effort aimed at evaluating the potential human health risk of perchlorate (ClO4) because of its presence at trace levels in some water systems.
Concern over potential effects on the thyroid gland in humans from perchlorate exposure and whether environmental levels pose a risk to human health have surfaced recently. In response to this concern, a broad collaborative effort spanning both private and government sectors has been engaged in extensive toxicological testing of perchlorate to add to our knowledge about how and under what exposure conditions perchlorate may cause effects in laboratory animals and in humans. The collaboration between the U.S. With respect to the EWG’s Report entitled “Rocket Science” which alleges human health risk from perchlorate in drinking water, ACSH concludes the following:

Environmental Research Volume 118, October 2012 Biomarkers of perchlorate exposure are correlated with circulating thyroid hormo.
Abstract Previous epidemiological studies provide conflicting evidence as to whether environmental perchlorate exposure can affect levels of circulating thyroid hormones in the general population.
We investigated the statistical relationships between biomarkers of perchlorate exposure and serum thyroid hormone levels in 2007–2008 National Health and Nutrition Evaluation Survey (NHANES) subjects. Generalized additive mixed models (GAMMs) were developed to estimate the relationships between T3 and T4 levels and creatinine-adjusted urinary perchlorate excretion.
The models included covariates related to gender, age, ethnicity, income, smoking status, prescription medications, and biomarkers of exposures to other goitrogenic ions and phthalate ester metabolites. Where necessary, relationships between hormone levels and covariates were represented as nonlinear smoothed terms.

CALIFORNIA DEPARTMENT OF PUBLIC HEALTH 10/05/12 Perchlorate in Drinking Water. Last Update: February 26, 2014 Perchlorate is a regulated drinking water contaminant in California, with a maximum contaminant level (MCL) of 6 micrograms per liter (µg/L).
The MCL became effective October 2007. For information provided to public water systems by the CDPH Drinking Water Program about the implementation of the MCL and the scheduling of monitoring, see links at the bottom of this page. Perchlorate and its salts are used in solid propellant for rockets, missiles, and fireworks, and elsewhere (e.g., production of matches, flares, pyrotechnics, ordnance, and explosives). Their use can lead to releases of perchlorate into the environment. Perchlorate. Production and use Perchlorate salts are produced industrially by the oxidation of solutions of sodium chlorate by electrolysis.
This method is used to prepare sodium perchlorate. Four perchlorates are of primary commercial interest: ammonium perchlorate (NH4ClO4), perchloric acid (HClO4), potassium perchlorate (KClO4), and sodium perchlorate (NaClO4). The main application is for rocket fuel. Perchlorate is commercially produced as solid salts of ammonium, sodium, and potassium cations; it is used as an oxidizer in solid propellants for rockets, missiles, fireworks, and certain munitions and used in the manufacture of matches.

In addition to overseeing the cleanup of sites contaminated with perchlorate, AB 826, the Perchlorate Contamination Prevention Act of 2003, required DTSC to adopt regulations specifying best management practices for perchlorate and perchlorate-containing substances.
The Perchlorate Best Management Practices were adopted on December 31, 2005 and became operative on July 1, 2006. If you are in the Department of Defense or you are in an industry centered on aerospace, fireworks, pyrotechnics, amusement parks, automobile air bag and safety restraint, lithium perchlorate batteries, or if you are in a public safety agency, the Perchlorate BMPs may apply to you. Others that may be affected by these regulations include farmers who use perchlorate-containing fertilizer, laboratories, bleach manufacturers and users, and Publicly Owned Treatment Works (POTWs).
Even households may be affected. For more information, please contact Ed Nieto at (916) 322-7893.
