1700 micrograms per cubic meter at a distance of 1.5 meters from the smoker. A related study found that pm 2.5 levels in non-smoking offices are about seven times higher than those in non-smoking offices. Smoking can make indoor pm 2.5 soar instantly, so it is best not to smoke indoors...
Environmental Protection Agency or EPA estimated that 8 percent of women of child-bearing age could have blood-mercury levels above a safe amount, determined to be 5.8 ug/L, or micrograms per liter [source: EPA]. And what's safe for an adult is not necessarily safe for a fetus -- or ...
A person's blood cholesterol level is 245 mg/dL. (1 g = 1000 mg; 1 L = 1000 mL). What is the cholesterol concentration in ppT (part per thousands) and ppm (parts per million)? To convert grams to micrograms, the number of grams by. ...
And it is something to be concerned about: As recently as 2000, the U.S. Environmental Protection Agency or EPA estimated that 8 percent of women of child-bearing age could have blood-mercury levels above a safe amount, determined to be 5.8 ug/L, or micrograms per liter [source: EPA]....
ppm means mg per litre. mg/l means 100ug/dl. Therefore there are 10 x 10 micrograms per decilitre in ppm. In other words, 10ug/dl is 0.1 ppm. How do you convert microgram per gram to ppm? Oh, dude, it's like converting microgram per gram to parts per million (ppm) is a piec...
A) 0.003 B) 0.3 C) 3 D) 3000 Parts Per Million: Parts per million (ppm) is one way of expressing the concentration of a solute in a solution. Parts per million is typically used when the concentration is very low. That is, the solute i...
EPA's drinking water standard reveals the maximum concentration of contaminants allowed. This concentration can be given implying various units. Since, allowed concentration is quite low, units like mg/L, ppb etc are used. Answer and Explanation:1 ...
A patient is prescribed 0.5 g of an antibiotic every 12 hours. The antibiotic liquid is labeled 250 mg/5 mL. a. How many mL should be used at each dose? b. How many mg of antibiotic are in each dose? c. How many u...
These values are far from the threshold of concern of 540 micrograms/person/day derived from an extensive database on chronic and subchronic diseases in animal studies [74]. However, the main concern regarding HMF consumption centers around its conversion to sulfoxymethylfurfural (SMF) by ...
