arsenic and lead levels in the ferts we use, its high, to high

T

this blew my mind.
 
the epa have set a limit of .010 PPM Parts per million as a safe level of arsenic in drinking water. the "action level" for lead= 0.015 ppm
 
Check out whats in our ferts ...

You can't apply drinking water standards to fertilizer. From the second paper posted by thismembername:
"background" arsenic level in US soil: average = 7.2 ppm
 
Adding even the worst of the ferts you listed would actually reduce the concentration of arsenic in the average US soil.
 
arsenic (like just about everything else in the world) is only bad for you in high concentrations - enough of anything in large amounts will kill you, even the building blocks of life like water, oxygen and carbon.
i wouldnt worry so much about it.
 
I put Cow Shit directly in my garden.
But thanks to Google, I don't eat it.
 
I don't put ANY of the the nutrients it takes to grow a Carrot directly on my dinner plate either.
 
I'm OK.
 
Minnesota department of health
http://www.health.state.mn.us/divs/eh/hazardous/topics/arsenic.html
Levels of arsenic in soil from 5 ppm up to 20 ppm are generally viewed as safe
 
 
cleanup levels are +20 ppm for arsenic and +250 ppm per lead
 
if im using Supreme growers kelp blast once a week which is listed as Lead: 10.51 I could assume that within a year due to buildup  your ppm could reach hazardous levels.

everyone is talking about arsenic in rice, baby formula, etc  in the levels of ... 200 ppb, with a federal limit of 10 ppb of arsenic in drinking water, one serving of rice will put you over that threshold.
 
if Great White Mycos is 4.35 ppm = 4350 ppb ... the safe limit for drinking water is 10 ppb.  something doesn't seem right about that.


oddly enough the products ive seen with the lowest levels of heavy metals is from MG
 
Didn't the old murder mysteries teach us that a build up of arsenic will help build a tolerance? That way, if someone decides to poison you, you can just laugh it off.
 
Time to get some All purpose plant food and put it on my hamburger like seasoning salt. :rolleyes:

You could assume that, but you would be wrong. Recommended dose 5g/gal. If you watered the whole gallon into a single potted plant containing 1 kg of soil every week for a year, that is 250g of product at 10 ppm = 2.5 mg of lead. Even if 100% is left behind (which will not be the case) you are left with 2.5 mg/kg = 2.5 ppm in the potting soil.
 
If you are using the stuff on your in-ground plants you would go bankrupt long before you could accumulate enough lead to even be measurable.

Very true. I find that a little Slayer is just what my plants need from time to time. They are much happier than when listening to that pop crap my daughter likes.  :onfire:
 
just to add my two cents the FDA changed the allowd amount of Mercury in tuna which is now higher than before and raised the amount of arsenic found in rice,  two foods that many kids eat the most of.
I can't see how by allowing the amounts of something toxic to be raised makes its any less safe to eat. I'm old and it might not harm my brain or body any worse than the years of drinking and smoking all ready has, but to say its ok and just rinse the rice off more or eat less tuna makes it ok. I wonder when they will start saying that steroids found in meat  and milk products is ok.
I know that there are places where heavy metals are not just high in water, but at toxic levals in the soil also to a point that the people there have a very high death rate early in life and a high death rate in babies before their first year. India is just one place where the water and soil has toxic levels, same goes for Vietnam, and large parts of China. I can bet you can find areas right here in the states that has very high to down right toxic.  
So are we any better off now than before? I guess its what each of us conciders what is a safe amount and what isn't, I can only hope that our children and they children don't pay the price if we're wrong.  
 
from what i am reading, the government and EPA found out that it has become common practice for fertilizer company to process toxic waste and sell it as "fertilizer", this is why some states have very strict heavy metal laws.
 
Stuff like, mining tailing, wood ash (that has chemically treated wood), electronic waste
 
from what i read Canada has stricter laws than the US to protect consumers from these heavy metals, but im still looking into it.
 
Here is my point.

This is maxicrop Soluble Seaweed Powder. It has 36 ppm of arsenic. Some states set the cleanup level of arsenic in soil at 20 ppm (parts per million). This means with one application of this product, your soil has just become a toxic dump site that needs to be cleaned to be safe. Yummy!
 
This is if you use the product as labeled. Think about all the times you have doubled up on a fert.

Who cares! Sweet n lo caused cancer for years and now it doesn't. There is toooooooo much information out there.

Sorry edit for spelling

sweet n lo = Monsanto .... evil
 
Point is you don't use it undiluted so 36 ppm becomes 3.6ppm if you use 10ml per 1 litre water. This is then further broken down by the soil and plants... Net result = dying of a stress related disease worrying about nothing. Don't apply too much too often and you will be fine
 
As soon as you add it to the soil it is diluted. Add 1 pound of fertilizer to 100 pounds of soil and the ppm is reduced by a factor of 100 (101 really). You have to look at it as weight of toxin per total weight of soil. milligram per kilogram is the same as ppm.
 
I am not saying that adding arsenic or lead to your soil is good, but nobody needs to panic. All of the heavy metals are naturally occurring substances that are present at some level in all soil. Even the crunchiest Oregon pure organic farm has lead, arsenic, nickel, and every other metal in their dirt.
 
I apologize, I think my previous post was mis-read. I meant to point out how the OP was missing the fact that those were the levels in the concentrated solution, not diluted for usage.
