Pak Green, use latest vehicle emission measurement technology to ensure that policy focuses on only the most polluting sectors of the vehicle fleet. By accurately measuring real-world driving emissions, we deliver the local insight necessary to inform the cost-effective design of low-emission policy. Our remote sensing equipment accurately measures real-world driving emissions from thousands of vehicles, under actual driving conditions, in a short space of time and without interfering with the vehicle whose emissions are being measured.

We measure real world driving emissions of nitric oxide, nitrogen dioxide, particulate matter, hydrocarbons, carbon monoxide and ammonia. Bespoke measurement campaigns are designed to explore real-world driving emissions at locations selected to maximize the benefit to the design of low-emission policies.

The design and development of cost effective, evidence-based, Clean Air and Low Emission Zone strategy and pollution mitigation schemes through:
  • Real-world driving emissions measurements that accurately characterize the vehicle fleet mix, identifying the most polluting vehicle types (i.e. buses, heavy goods vehicles, vans and cars) and their respective contributions to emissions.
  • Quantified and highly disaggregated emissions data to underpin robust mitigation measures.
  • Assessing abatement technology performance over time.
  • Measurement data to support compliance management within Clean Air and Low Emission Zones.
The improvement of local air quality emissions inventories and modelling through:
  • The provision of vehicle-emissions data that are consistent with existing vehicle classes used in emission factor and emission inventory development.
  • Accurate road traffic counts and detailed vehicle information via automatic number plate recognition (ANPR).
  • The delivery of insights such as the fraction of primary nitrogen dioxide emissions and the potential for ammonia emissions from modern selective catalytic reduction technologies.
  • Significantly reduced modelling uncertainty for baseline and mitigation scenarios by removing assumptions and replacing them with evidence-based, real-world driving emissions information.
  • High-volume sample sizes, at multiple locations, ensuring the evidence base is representative of the fleet in the area of interest.

Optimization of model performance at key road links.

Meteorology is the study of the Earth’s atmosphere and the variations in temperature and moisture patterns that produce different weather conditions. Meteorology plays an important part during the environmental survey and study.

Meteorological phenomena are described and quantified by the variables of Earth’s atmosphere as follows:
  • Wind speed and direction
  • Air temperature
  • Air pressure
  • Air humidity
  • Precipitation
  • Haze and contents of the air
  • Solar and terrestrial radiation

At different spatial scales are used to describe and predict weather on local, regional, and global levels.

1. Lux Level Monitoring

Likewise, excessive levels of artificial light produce annoyance and can adversely affect health. These detrimental effects may depend on the spectrum as well as the overall brightness level of light. LUX level according to our national and international environmental standards.

2. Noise Level Monitoring

Noise survey is conducted in areas where noise exposure is likely to be hazardous. Noise level refers to the level of sound. A noise survey involves measuring noise level at selected locations throughout an entire plant or sections to identify noisy areas.

Noise pollution has adverse health outcomes, including heart disease and hearing loss. Reducing environmental noise pollution is achievable and consistent with national prevention goals.

Areas we cover:
  • Commercial areas
  • Construction sites
  • Indoor Laboratories
  • Roads/ Highway
  • Generator Areas / Canopy
  • Industrial Estates

Water is a vital natural resource which is essential for multiplicity of purpose. water quality standards describe the quality parameters set for drinking water. Drinking water or potable water is water safe enough to be consumed by humans. In most developed countries, the water supplied to households, commerce and industry meets drinking water quality standards, even though only a very small proportion is actually consumed or used in food preparation.

Meteorological phenomena are described and quantified by the variables of Earth’s atmosphere as follows:
  • Wind speed and direction
  • Air temperature
  • Air pressure
  • Air humidity
  • Precipitation
  • Haze and contents of the air
  • Solar and terrestrial radiation

At different spatial scales are used to describe and predict weather on local, regional, and global levels.

We provide analytical services for many clients including municipal agencies, NPDES permit holders, metal finishing industries, engineering films, chemical suppliers, and consulting firms.

From working with our clients we have gained a strong background in various facets of the environmental industry.

Industrial hygienists use environmental monitoring and analytical methods to detect the extent of worker exposure and employ engineering, work practice controls, and other methods to control potential health hazards Occupational Health and safety is the main focus during the Compliance reporting of Industrial Hygiene.

Industrial hygienists analyze, identify, and measure workplace hazards or stresses that can cause sickness, impaired health, or significant discomfort in workers through chemical, physical, ergonomic, or biological exposures. Two roles of the OSHA industrial hygienist are to spot those conditions and help eliminate or control them through appropriate measures.

When workers are exposed to chemical and physical agents, industrial hygiene programs and practices help mitigate acute and chronic health issues. Gabriel has conducted Occupational Safety and Health Administration (OSHA) audits, completed monitoring studies, implemented protective measures, and organized health and safety programs since last many years. Pak Green complete expertise in industrial hygiene and OSHA regulations allows us to look at the big picture and also develop focused, customized solutions.
