Chlorophenols impart unpleasant taste and odor to drinking water at concentrations as low as 5 mg/m3. They are formed when the chlorine dis- infection process is applied to phenol-containing waters. What is the threshold for unpleasant taste and odor in units of (a) mg/L, (b) mg/L, (c) ppmm, and (d) ppbm

Chlorine’s disinfection properties have helped improve the lives of billions of people around the world. Chlorine also is an essential chemical building block, used to make many products that contribute to public health and safety, advanced technology, nutrition, security and transportation.

The threshold for unpleasant taste and order in the respective units are;

A) 0.005 mg/L

A) 0.005 mg/LB) 5 μg/L

A) 0.005 mg/LB) 5 μg/LC) 0.005 ppm

A) 0.005 mg/LB) 5 μg/LC) 0.005 ppmD) 5 ppb

We are given the concentration of chlorophenols as; M = 5 mg/m³

A) Converting mg/m³ to mg/L means that;

1 mg/m³ = 0.001 mg/L. Thus;

5 mg/m³ = (5 × 0.001)/1

>> 0.005 mg/L

B) Converting mg/m³ to μg/L means that;

1 mg/m³ = 1 μg/L

Thus; 5 mg/m³ = 5 × 1/1 μg/L

>> 5 μg/L

C) Converting mg/m³ to ppm gives;

1 mg/m³ = 0.001 ppm

Thus;

5 mg/m³ = (5 × 0.001)/1 ppm

>> 0.005 ppm

D) Converting mg/m³ to ppb gives;

1 mg/m³ = 1 ppm

Thus;

5 mg/m³ = 5 × 1/1 ppb

>> 5 ppb
