Source Apportionment (SA) is a practice of deriving insights about pollution sources and the amount they contribute to ambient air pollution levels. This thing can be accomplished using three main approaches:

• Emission Inventories
• Source-Oriented Models
• Receptor-Oriented Models

Data generated over the years reveal that particulate matters are exceeding more than the permissible levels at many locations, particularly in urban areas. Air pollution problem becomes complex due to multiple and complex air polluting sources such as,

• Industries
• Construction activities
• Automobiles
• Domestic fuel burning
• Roadside dusts, etc.

Source apportionment study is primarily based on measurements and tracking down the origin of sources through receptor modeling and helps in identifying the sources & extent of their contribution. Source-apportionment processes aim to determine the role of given sources to air pollution levels. AIRSHED is equipped with all the tools and techniques that are required to conduct source apportionment studies based on Receptor and Dispersion Model.

A Greenhouse Gas Emission (GHG) inventory is a list of emission sources and its associations quantified using UNFCC, ISO, USEPA standardized methods. Organizations need to understand and plan to manage their GHG emissions to ensure long-term success in a competitive work environment.

GHG emission inventory provides business with information that can be used to build an effective strategy to manage GHG emissions which leads to improved governance around Climate Change risks and opportunities. ISO 14064 is one of the international standards which provides guidance for Developing GHG emission Inventories. AIRSHED develops GHG emission inventory as per ISO 14064/GHG protocol.
AIRSHED supports the development of air pollutant and greenhouse gas emission inventories for clients and national governments to fulfil their international reporting requirements.

Carbon Neutrality as per PAS 2060

Carbon Neutrality is a “condition in which there is no net increase in the global emission of greenhouse gas to the atmosphere as a result of the greenhouse gas emissions associated with the subject” (PAS 2060, BSI).
Carbon Neutrality results in Brand Differentiation and increased customer recognition along with cost and energy savings. It lets the organizations move towards a path of low carbon growth and carry out business process responsibly. PAS 2060:2014 particular requirements are to be met by any organization seeking to demonstrate Carbon Neutrality through the means of quantification, reduction and offsetting of greenhouse gas (GHG) emissions. AIRSHED develops carbon Neutrality Strategy and assists companies to become Carbon Neutral.

Air Dispersion Modelling uses mathematical formulations to categorize the atmospheric processes that disperse a pollutant emitted by a source and for that AIRSHED has previously worked and currently working closely with state meteorologists and research institutes.

Assessing impacts of air emissions from

• Point Sources
• Area Sources
• Line Sources
• Through dispersion model at industrial facility level, local level, city level

AIRSHED offers comprehensive modelling expertise across a wide variety of sectors through dispersion model at industrial facility level, local level and city level. AIRSHED uses air dispersion models such as:

• AERMOD
• CALPUFF
• CAMx
• CMAQ
• CHEM

Our team comprises of multidiscipline professionals such as chemical engineers, civil engineers, meteorologists, chemists, statisticians, risk assessors, toxicologists, epidemiologists, and pharmacologists who are experts in inhalation & air toxics health risk assessment.

Inhalation and Air toxic health risk assessment evaluates the health impact to be expected from measuring the effects of air quality, in different socioeconomic, environmental, and policy factors so hence, it is an important tool for notifying public policy decisions. We recognize that the complete assessment of a human health or ecological risk is a significant milestone in the successful and smooth process of an organization.

The 4 Step Risk Assessment Process:

• Hazard Identification – What are the health problems are caused by toxic pollutant.
• Exposure Assessment – How much of the pollutant do people are exposed to and how much they inhale it during a specific time period?
• Dose-Response Assessment – What are the health problems caused at different exposures?
• Risk Characterization – What are the other factorial risks of health problems in the pollutant exposed population?

GIS-Based Pollutant Mapping helps in development of high-resolution thematic layers of primary air pollutants (SOx, NOx, CO, VOCs and PM) and air pollution sources (industries, automobiles, domestic fuel burning, etc.), for the effective measurement and mapping of air pollutants that are harmful emitting widely from the vehicular and industrial sources.

A geographic information system (GIS) is a computer-based tool for mapping and analyzing geographic phenomenon that exist and events that occur on Earth. Air quality is one of the most significant factors to our health and environment, but sources of contamination are often difficult to monitor. GIS technology manages statistical and spatial data that provides a tool that shows the relationship between poor air quality and occurrences of deficient human and environmental health. Hence, in this manner, GIS assists in monitoring pollutant emissions. A GIS can be used to track the pollutant emissions by delineating the effects of ozone, smog, dust, and other harmful airborne pollutants on plant and human life.

By monitoring those alliance, a GIS becomes a tool conservationists can use to ensure that no further pollution occurs. GIS technology allows us to locate from where the toxic pollutants are coming from and monitor those areas for change to conserve the air quality and our experts at AIRSHED assist you with the solutions to overcome those challenges to an extent.

Good Indoor Air Quality helps in improving the personal well-being and health of your employees. So, there is no doubt that the working premises with good quality of air are more productive workplaces.
AIRSHED is working with the clients to strategize and implement real-time compliance solutions using innovative approaches and advanced technology to monitor and assess pollutants to improve the Air Quality. We also provide an Indoor Air Quality assessment that will instigate good environmental management of every aspect of your workplace.

Many toxic pollutants that impact the indoor air quality come from the sources inside of a building, though some are drawn in from outdoor activities. Among the most common pollutants are:

• Volatile organic compounds (VOCs)
• Carbon monoxide (CO)
• Particulate matter (PM)
• Radon
• Carbon dioxide
• Nitrogen dioxide
• Methane

AIRSHED offers an indoor air quality testing service which helps you attaining the peace of mind, realizing that you are providing a healthy and safe working environment for your employees. We offer reliable and responsible information and an extremely advanced and cost-effective process of certification. If you are dealing with multiple sites, our long-term monitoring methods and techniques standardize and systematize corrective action across all sites and help in reducing your operating costs.
