IEQ refers to the quality of a building’s environment in relation to the health and wellbeing of people occupying it. IEQ is determined by many factors and contaminants impacting health conditions of the building occupants often leading to a sick building syndrome.
Various respiratory symptoms and illnesses can be associated with sick building characteristics, including dampness, cleanliness, and ventilation characteristics. Indoor environments are highly complex and building occupants may be exposed to a variety of contaminants such as various gases and particulates emanating from office machines, cleaning products, construction activities, carpets and furnishings, perfumes, cigarette smoke, water-damaged building materials, microbial growth (fungal, mold, and bacterial), insects, outdoor pollutants and many other factors. Understanding the sources of indoor environmental contaminants and controlling them can often help prevent or resolve building-related worker symptoms.

Municipal solid waste (MSW) is a heterogeneous refuse from households, non-hazardous solid waste from industrial, commercial and institutional establishments, market waste, yard waste and road sweepings. It poses a great health and environmental hazard and needs to be scientifically managed in terms of collection, transfer, treatment and disposal.

Effective MSW Management depends upon an appropriate distribution of responsibilities among many stakeholders including local self-government. Like all the waste management strategies, MSW also first needs to be fully characterized over all the seasons and localities.

All forms of life rely on an active hydrosphere and human beings are particularly interested in the fresh water hydrosphere as the rivers are of immense importance geologically, biologically, historically and culturally. Water quality monitoring is one of the first steps required in the rational development and management of water resources to maintain their wholesomeness and pristine.
In the field of water quality management, there has been a steady evolution in procedures for designing system for the designated best use. The monitoring comprises all activities to obtain information, including water characteristics, with respect to the water system.
It is a fact that the natural water courses are exposed to variety of pollution at various degrees; hence it becomes essential to measure the suspected contaminants for their management.

Sewage and sullage are generated from household activities and other domestic usage of water. As sullage weak wastewater and is generated from non-toilet usage of water, such as bath or handwash, it still contains microbial and organic, inorganic pollutants. Therefore, both type wastewaters need to be tested for their respective treatment approaches and generally following parameters can give their characteristics.

• Chemical oxygen demand (COD)
• Chlorides
• Faecal coliforms
• Heavy metals
• pH
• Sulphates
• Total dissolved solids
• Total oil & grease
• Total suspended solids
• Available nitrogen
• Bromide
• Bulk density
• Chlorides
• Chlorine demand

Clean air is considered to be a basic requirement of human health and well-being. However, as air pollution continues to pose a significant threat to health worldwide, a significant urban population is exposed to the burden of disease due to air pollution. Legislative framework has long been established for the Air quality standards, both ambient air and for workplace, which need to be maintained by the respective stakeholders.
