Air quality assessment is a measure of how clean or polluted the air is. Monitoring the air quality of the environment is a prime concern for human beings because all of the things in the world directly, indirectly, or partially depend on the environment. For this reason, it is necessary to measure the air quality condition.

Noise Level Assessment is a process to identify noise hazard areas using a noise level meter. Data collected from noise level monitoring and testing helps us to understand the conditions and action that can be taken to reduce noise pollution.

Temperature is the measure of warmth or coldness in reference to a set standard, often expressed in terms of degrees Fahrenheit or Celsius. Humidity refers to the amount of water vapor, or moisture, in the air.

Light or visible light, commonly refers to electromagnetic radiation that can be detected by the human eye. The entire electromagnetic spectrum is extremely broad, ranging from low energy radio waves with wavelengths that are measured in meters, to high energy gamma rays with wavelengths that are less than 1 x 10-11 meters.

Stack air emission assessment is a process to identify harmful exhaust gases. Basically, gases are released into the air from boiler stacks, chimneys or diesel generator set stacks, etc. from various industries after the incineration process, i.e. method to remove or burn harmful gases before releasing them into the environment.

Ozone Depleting Substance gas leak detection test is a process of identifying whether any leak exists in the joint, pipe or body of air conditioning systems or refrigeration systems.

GHG/Carbon Footprint Assessment is a process to identify the list of emission sources and the associated emissions and is quantified using standardized methods.

Volatile Organic Compound Assessment is important because volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands. By identifying the area and measuring the quantity of VOCs around the area we can take the necessary steps.

Environmental Impact Assessment (EIA) is a tool used to assess the significant effects of a project or development proposal on the environment. EIAs make sure that project decision-makers think about the likely effects on the environment at the earliest possible time and aim to avoid, reduce or offset those effects. This ensures that proposals are understood properly before decisions are made.

An Environmental Management Plan (EMP) is a guidance document to measure and achieve compliance with the environmental mitigation and monitoring to be taken during implementation and operation to eliminate adverse environmental and social impacts of an industry or project, offset them, or reduce them to acceptable levels.
