An attempt has been made to determine the levels of benzene in air at different locations in Mumbai city. Levels of benzene in air have been determined by adsorbing air at a uniform flow rate on especially fabricated activated coconut charcoal cartridges followed by Cited by: Ambient levels of benzene in Mumbai city Article in International Journal of Environmental Health Research 14(3) July with 53 Reads How we measure 'reads'.

The study focused on target VOCs as defined by USEPA. Concentrations of benzene, at all the locations, were found to be much above the guidelines values prescribed by World Health Organization (WHO) for ambient air quality.

All other VOCs were observed to be below the WHO guideline values. The results show that levels of VOCs in Mumbai were by: Benzene. Benzene. Hazard Summary. Benzene is found in the air from emissions from burning coal and oil, gasoline service stations, and motor vehicle exhaust.

Acute (short-term) inhalation exposure of humans to benzene may cause drowsiness, dizziness, headaches, as well as eye, skin, and respiratory tract irritation, and, at high levels, unconsciousness.

From another side, the AQD gives several requirements regarding metrological aspects setting very low levels of benzene to be monitored: the limit value (LV) for benzene is 5 µg/m³ (about nmol/mol at 20 °C and kPa) over a calendar. Overall, it has been estimated that 10 kg of benzene is lost per ton of benzene produced during transfer and storage, with approximately 94% lost as air emissions and 6% as water efflu­ ents [1].

It is therefore found in ambient air, water, and soil. For example, benzene has been detected in Cited by: 1. Benzene (C.

Benzene is regarded as the most hazardous compound of the BTX group. The International Agency for Research Cancer (IARC) and United State Environmental Protection Agency (USEPA) have classified benzene to be a Group A and CLASS 1 human carcinogen respectively [] but, toluene and xylene do not fall in this group [18,19].Short term human exposures to relatively high concentrations of benzene can.

Benzene has been measured in air inside vehicles at levels higher than those in residential air, but substantially lower than those at petrol filling stations. Food and water. Waterborne and foodborne benzene contributes only a small percentage of the total daily intake in non-smoking adults.

Fifty two per cent were exposed to an average of μg/m 3, while 8% received maximum exposure concentrations in the region of – μg/m by: Benzene is an air toxic emitted from gasoline service stations, motor vehicle exhaust and fuel evaporation, the burning of coal and oil, and various other sources.

In addition to being a common air pollutant, benzene may also contaminate water. Urban areas generally have higher ambient air concentrations of benzene than other Size: KB. Extended Cox regression modeling was used to estimate hazard ratios (HR) and 95% confidence intervals (CI).

Among all participants, ambient benzene was positively associated with myelodysplastic syndromes (HR =95% CI: – per μg/m 3) and T‐cell lymphoma (HR =95% CI: – per μg/m 3).Cited by: 1. A comprehensive evaluation of the adverse health effects of human exposures to BTX from service station emissions was carried out using BTX exposure data from the scientific literature.

The data was grouped into different scenarios based on activity, location and occupation and plotted as Cumulative Probability Distributions (CPD) plots. Health risk was evaluated for each scenario using the Cited by: @article{osti_, title = {Benzene levels in ambient air and breath of smokers and nonsmokers in urban and pristine environments}, author = {Wester, R C and Maibach, H I and Gruenke, L D and Craig, J C}, abstractNote = {Benzene levels in human breath and in ambient air were compared in the urban area of San Francisco (SF) and in a more remote coastal pristine setting of Stinson Beach.

Benzene is used in Canada in a variety of ways that result in it entering the Canadian environment. Vehicle emissions are the major source of benzene release to the environment.

Releases of benzene result in measurable concentrations in the various media to which humans and other organisms may be exposed. In Canada, the primary source of human exposure to benzene is ambient and indoor air.

The Ministry of Environment of South Korea uses the Comprehensive Air-quality Index (CAI) to describe the ambient air quality based on the health risks of air pollution. The index aims to help the public easily understand the air quality and protect people's health.

The CAI is on a scale from 0 towhich is divided into six categories. Exposure to ambient air pollution is a major risk factor for global disease. Assessment of the impacts of air pollution on population health and evaluation of trends relative to other major risk factors requires regularly updated, accurate, spatially resolved exposure estimates.

We combined satellite-based estimates, chemical transport model simulations, and ground measurements from 79 Cited by: The aim of this study was to investigate the relation between two toxic volatile organic compounds, 1,3-butadiene and benzene, and a commonly used indicator of vehicle exhaust fumes, NO2.

This was to see if NO2 can be used to indicate personal exposure to carcinogenic substances or at least estimate ambient.

Combined with information provided by stakeholders, manufacturers and literature, the review considers commercially available sensors, including PID-based sensors, semiconductor (resistive gas sensors) and portable on-line measuring devices.

Ambient Monitoring Results. Ambient levels of benzene are routinely monitored at approximately twenty sites in the California air toxics monitoring network.

The statewide average concentration of benzene during was ppb (parts per billion). and winter when buildings are less-well ventilated, benzene levels are even higher. The Environmental Protection Agency (EPA) classifies benzene as a Group A* carcinogen and has estimated that a lifetime exposure to ppm benzene in air will result in, at most, 1 additional case of leukemia in 10, people exposed.
