[5] If the air is contaminated in the workplace, more air exchange will lead to the inhalation of higher amounts of chemicals. [6]
The results from these interventions have been a mixture of good and bad results, ranging from an increase in clean air and water to the deterioration of the quality of coastal effluents due to the rapid use of different hygienic and sanitary supplies. [18]

Thus river water is converted into soft water by eliminating Ca and Mg ions and enhancing Na ions by coal-fired boilers. Soft water application in irrigation (surface or ground water) converts the fertile soils into alkaline sodic soils. [21]
