Science Fair Project: Testing for Arsenic in Apple Juice?

Water Testing BlogArsenic in Food, Arsenic in Juice, Arsenic in Water, Arsenic Test, Home Water Test Kits, Testing Devices, Water Test Kit

With so many news outlets discussing recent findings of arsenic in bottles of apple juice bearing brand names it comes as no surprise to us that we would receive an inquiry like the one we just got from ‘Hadiah’ who asked, “I would like to know exactly what arsenic testing kit i could use for my daughters science fair project. She is testing for arsenic in apple juice.

Arsenic in Water Test Kit 0, 5, 10, 20, 50, 100, 200 & >500 ppb (481396-2) 2 Tests, Results in 12 Minutes
Arsenic Quick™
0, 5, 10, 20, 50, 100, 200 & >500 ppb

Thus far in our limited research we have found only one kit that we THINK may have the ability to perform testing on various juices: Arsenic Quick. Why do we think this kit may have promise? Quite simply, its design (hanging the test pad reaction area above the liquid getting tested and relying solely upon arsenic gas liberated by a small quantity of food grade acid) means the color of the juice ought not interfere with reading the resultant color of the test pad after at the completion of the test.

Food grade acid? Liberated arsenic gas? Is this test SAFE?

Having performed the test numerous times ourselves, we can assure you that the test procedure and required testing reagents pose little to no harm to people performing the tests.

Food Grade Acid – Instead of using more caustic and potentially dangerous acids like other kits, the Arsenic Quick Test Kit uses tartaric acid, an acid commonly found in various ingredients used in foods most of us eat on a daily basis.

Liberated Arsenic Gas – While the directions for the Arsenic Quick Test Kit instruct testing personnel to perform testing in a well-ventilated area, the amount of gas generated by such a small sample should pose no risks.

But, just the same… open a window in the kitchen and turn on the stove exhaust fan (if you have one), test in the garage w/ the door open, or take some other precaution that will keep fresh air coming into the test area.

Proper precaution in any testing environment, even if the testing environment seems safe, always pays off!

Arsenic & Lead in Popular Juices — Not Good for Kids!

Water Testing BlogArsenic, Arsenic in Food, Arsenic in Water, Arsenic in Wood, Lead, Water Quality Testing, Water Testing

If you have not heard this already, studies have found that popular brands of juice contain higher than expected levels of arsenic, a naturally occurring toxic element known to cause definite health problems with prolonged exposure.

What juice brands contained arsenic? Name brands you might recognize included Minute Maid, Mott’s, Gerber, Welch’s, and Great Value ( source )

Did other brands ring in as containing arsenic, as well? Yes, and the same study also explored the lead content in various juices — and discovered that an alarming number of juice brands contained unsettling amounts of lead.

Scary times, in our opinion, when juice manufacturers — or the manufacturers of ANY food or beverage product — do not take into consideration contaminant levels like lead or arsenic regardless of whether or not the levels violate Federal Law.

We believe that companies who produce products intended for use or consumption by children really ought to hold themselves to higher standards than Federal Laws mandate since laws dictating food & beverage products — and possibly every aspect of our lives — only go on the books AFTER something becomes a problem, people get sick, someone dies, etc.

Many of you may have seen episodes of murder mystery shows where the killer used arsenic to poison his/her victims… because it WORKS as a lethal poison in the right doses and also causes debilitating conditions with prolonged exposure at lower levels.

We mentioned lead in the title of this article… so we will now tell you that the same study mentioned above ALSO determined that popular brands of juice contained higher than expected levels of lead, too.

For those not knowledgeable about lead in water or the effects of lead on the human body — especially young children — it will suffice to say that it does bad, bad things and you do not want it in your food or water.

Over the years we have posted numerous articles about lead in water, testing for lead in water and various ways to remove lead from drinking water. Check out those lead in water postings in the Water Testing Blog ‘Lead’ Archives.

Low Levels of Arsenic Exposure Lowers Resistance to Influenza

Once again arsenic has made the news and this time scientists have discovered a possible link between low levels of arsenic exposure and a decrease in the human body’s ability to fight the influenza virus. ( source )

What is Arsenic and Where Does It Come From?

Free arsenic which can adversely affect human health comes from a reaction between certain types of igneous (volcanic) rock and oxygen when a water table (aquifer) drops. This reaction liberates ‘free’ arsenic and once the water table rises again, that ‘free’ arsenic gets carried away by the ground water.

What About Surface Water? Can Arsenic Get Into Surface Water?

Many bodies of surface water get fed by run off from streams and tributaries which get their water originally from underground sources. Additionally we must not forget that “fly ash containing arsenic can be a potential source of contamination to both surface water and ground water.” ( source )

How Can Private Individuals Test Their Water for Arsenic?

Yes they can, but please keep in mind that no at-home drinking water test kit for arsenic will suffice if you need a definitive answer as to whether or not your drinking water conatins arsenic. Only water analysis performed by a certified laboratory will provide you with those sorts of answers when dealing with water quality issues which can directly affect your health.

Why bother using an at-home test kits for arsenic in drinking water? Simple: Performing a simple screening for contaminants on your own between certified water tests greatly decreases your risk of exposure to harmful contaminats like arsenic.

Nationally recognized organizations such as the United States Environmental Protection Agency (USEPA) and the Well Owners Organization suggest testing for drinking water contamination on a regular basis, and not just when an event such as flood takes place.

The kit above has a detection range of 0.0, 0.005, 0.01, 0.02, 0.06, 0.1, 0.3, 0.5, <0.5, <0.5 ppm (mg/L) and you may also use this kit for determining the arsenic concentration of soil. With a total test time of just 12 minutes, this inexpensive (< $20 USD) home water test kit makes testing well water, groundwater, surface water and all forms of drinking water a breeze!

Dangerous Arsenic Levels in Food

Water Testing BlogArsenic, Arsenic in Food, Arsenic in Water, Arsenic Test, Food Processing

Although this blog tries to deal mainly with water quality and matters directly related to water quality testing, the following bit of information about dangerous levels of arsenic in food caught our attention and we felt compelled to post it:

“A lack of regulation means a third of baby rice on sale in the UK contains worryingly high levels of carcinogenic inorganic arsenic, according to researchers.

The study, carried out by scientists from the University of Aberdeen and published this month in the journal Environmental Pollution, said this meant some children could be getting six times the recommended inorganic arsenic for their weight.

The levels detected in some of the samples would be illegal in China, where there are stringent controls in place. But while there are European Union and American regulations for arsenic levels in drinking water, there are currently no laws to direct the amounts of arsenic allowed in food products.

Furthermore, current guidelines on intake are based on outdated research conducted before arsenic was found to be a carcinogen, according to the researchers.

This calls into question the need for am urgent review on the situation.

“It is apparent that inorganic arsenic levels in baby rice should be of concern,” said lead scientist, Andrew Meharg.

Pretty frightening stuff. We cannot help but wonder if the methodology used to test arsenic levels in soil with the Arsenic Quick test kit could also work for testing arsenic levels in certain types of foods.
