Question

Persons are medically considered to have lead poisoning if they have concentration of greater than 10 micrograms of lead per decilitre of blood. Concentration in parts per billion is?

Answer 1

Answer:

Explanation:

10 microgram is 10* 10-3 in 10-1 litres

so the ratio can be written as 100/1000 g/l

Now you can easily convert it to Parts per billion

Answer 2

Hey Dear,

◆ Answer -

Lead concentration above 100 ppb is considered as lead poisoning.

◆ Explanation -

Here, we will assume blood has density of water. Thus 1 dl = 0.1 L = 100 g

Also we'll convert micrograms to grams.

10 μg = 10 × 10^-6 g

10 μg = 10^-5 g

Therefore, concentration in parts per billion is calculated bh -

Concentration = (10^-5 / 100) × 10^9 ppb

Concentration = 100 ppb

Hope this helps you. Thanks for asking..
