Some 15 years ago, scientists realized that the rice plant was unusually effective at absorbing toxic forms of arsenic from soil and water - but no one had directly connected eating rice with actual harm to health. That changed in July when U.K. and Indian scientists reported that daily ...
The one concern is with its potential to disrupt the reproductive system. Studies have not been done in humans regarding this; however, potential reproductive issues in mice are suspected from high levels of (ingested) borax. Borax is acutely toxic in the same manner that salt is (in rats, ...
Why is carbon monoxide toxic for humans? Explain why you agree or disagree with the following statement: We should not worry much about exposure to toxic chemicals because we can use genetic engineering to reduce our susceptibility to their effects. ...
Involvement of AhR and AhR-regulated genes has also been suggested as one of the effects caused by metals in various tissues, particularly toxic heavy metals[26]. Increased expression of AhR mRNA has been noted in a human keratinocyte cell line (HaCaT cells) in response to arsenic[27]. In ...
The plant's metal transporters responsible for the uptake and stabilization of metals in plant cells become saturated due to increased metal uptake, leading to competition between different metals, particularly nones- sential metals such as cadmium (Cd), arsenic (As), and lead (Pb). The ...
The sensitivity of the bioluminescence test systems, when compared to those of other bioassays is, usually, sufficient to reveal any compound toxic to humans and other mammals. In some cases, the BL systems can have not enough sensitivity to detect a toxic substance at its Maximum Permissible...
Unfortunately, that argument doesn’t hold much weight.Humans are 20 times more sensitive to MSG than monkeys, 5 times more sensitive than rats.(6) We have glutamate receptors on every major organ, hard-wired into our brains, and even on the tip of our tongue! That means that one fifth...
Settlement densities of humans tended to rise from unblemished mountain locations towards the more polluted lowland regions. To formulate a working hypothesis, we anticipated that the downstream level of antibacterial resistance would increment. At eight distinct stations along the Qishan River, and at ...
things in small quantities, but deleterious in high quantities. For humans, theMayo Clinic recommendsa daily allowance of 8 mg for women and 11 mg for men. But they warn us that “large amounts of zinc are toxic and can cause copper deficiency, anemia, and damage to the nervous system....
Death cap mushrooms are exploiting our interconnected world to start popping up in unexpected, new places. And it's not the only fungus taking advantage.
