Most forever pollutants have greater concentrations as you go up the food chain. The grass has 1ppm, the cow eats 100x it's body weight over its lifetime, and cannot eliminate the pollutant so it gets up to 100ppm. Add in a few more levels and it can really ratchet up the dosage.
- idontwantthis 3y agoI wonder if it’s worth it to filter the water you drink. If that’s at the bottom of the chain then would the amount you get from food (especially meat) vastly dwarf the amount you directly drink?
- tohnjitor 3y agoBut what is the water filter made from? What if it's also dependent on PFOA?
- idontwantthis 3y agoAlso a good question, but mine still stands. Do we get an significant amount of this directly from water?
- tohnjitor 3y agoI wish I knew, or maybe I don't. Sometimes it seems too late to be rid of these substances.
- ikekkdcjkfke 3y agoEventually it will accummulate in humans, so we treat humans as toxic waste?
- staunton 3y agoTo some degree, we do that already.
- BiteCode_dev 3y agoHuman bodies are already considered as such after death.
- ada1981 3y agoI’ve heard some people still consider “meat” to be food.
- tacocataco 3y agoAre you talking about the lab grown meat or meat substitutes? The lab grown stuff might be the only way we can eat meat without these chemicals in it now.
- ada1981 3y agoI’m talking about the stuff you get by killing animals.
- pvaldes 3y agoIs more complicated than that. If those chemicals are lipophilic substances (attracted by fat) then cows should accumulate more. But if they are hydrophilic substances, attracted by water, we need to remember that lettuce is 96% water. One Kg of meat is rich energy food and not equivalent to Kg of lettuce. We would need to eat much more Kg of lettuce for the same. As we are talking about chocolate pie I assume that they are lipohilic. But vegetables aren't an homogeneous group and some seeds and fruits have a lot of oil. We could find that meat is safer than some of them and expect a much higher variability inside the group than with meat.
- hammock 3y agoPFAS are extremely hydrophobic… that is one of their main appeals
- pvaldes 3y agoI assume this, but I don't know every chemical in this group. What is strange is that Kale does not seem like a very oily plant (in my opinion, could be wrong). This species store sugars as chill protection. The main question to ask here is if this chemicals are causing chronic inflammation and in that case if is related with the obesity epidemic. We know that people living in the upper course of the rivers and allegedly drink better quality water are less obese on average. A possible null hypothese to start could be: A body accumulating toxic substances in the fat cells, could react making more fat cells as a defense (to dilute the poison by cell)?. Are somebody checking if the areas with more chemicals in the water show a higher average of Body Mass Index?
