We are taking a conservative approach and this (new rules) is a "living document" that can be amended should further scientific evidence emerge.Q: What is the thrust of these new rules?A: What we will ask for eligibility of intersex athletes is that they reduce their testosterone levels to below five
nanogrammes per litre.
The researchers identified the minimum healthy level of 25-hydroxyvitamin D in blood plasma to be 30
nanogrammes per millilitre (ng/ml) and found to reach this, dietary supplements of 3,000 to 5,000 international units (IU) per day, less with the addition of moderate daily sun exposure with minimal clothing (approximately 10-15 minutes per day outdoors at noon) would be required.
More than 10,000 kilometers of rivers around the globe have concentrations of the drug in excess of the EU "watch list" limit of 100
nanogrammes per litre, the new research found.
The specified limit for cannabis is two
nanogrammes per 100ml of blood.
