The botulinum toxin as the most toxic substance known has an LD 50 value of 1 ng/kg, while the most non-toxic substance water has an LD 50 value of more than 90 g/kg; a difference of about 1 in 100 billion, or 11 orders of magnitude. As with all measured values that differ by many orders of magnitude, a logarithmic view is advisable.
The LD 50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children. [19] [20] However the widely used human LD 50 estimate of 0.5–1.0 mg/kg was questioned in a 2013 review, in light of several documented cases of humans surviving much higher doses; the 2013 review suggests that the lower limit causing fatal ...
As a rule of thumb the LOQ is approximately two times the LOD. For substances that are not included in any of the annexes in EU regulations, a default MRL of 0.01 mg/kg normally applies. [citation needed] It follows that adoption of GAP at the farm level must be a priority, and includes the withdrawal of obsolete pesticides.

Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
Just 1 mg of finasteride is proven to effectively treat male pattern baldness. You’ll typically see results within 3-6 months , and with consistent use, most men retain the majority of their ...
It is a chelating agent and binds to free iron in the body in order to be eliminated by the kidneys into urine. [8] Dosing of deferoxamine should be determined through consultation with a toxicologist but is typically continuously infused at 15 mg/kg to 35 mg/kg per hour and not exceeding the maximum daily dose of 6 grams for adults.
