European emission standards limit the CO 2 emissions of new passenger cars and light vehicles. The European Union average new car CO 2 emissions figure dropped by % in the year to the first quarter of , down to g/km. Water vapour. Vehicle . Road transport is known to be a major source of atmospheric pollution [8,9,10].Despite the fact that exhaust emission regulations for European passenger cars have been in force for more than 20 years, the desired improvements in air quality have not materialized yet [1,11].Therefore, the effectiveness of the Euro emission standards for road transport can be by:
Euro emissions standards. New cars have to meet European emissions regulations. The so-called ‘Euro 1’ standard came into force in and set limits for petrol car carbon monoxide (CO) emissions that could effectively only be met by fitting a catalytic converter in the exhaust system. Each new standard is tougher than the last. A commonly circulated online item about the dangers of benzene supposedly emitted by automobile components has been widely misunderstood: Do not turn on A/C immediately as soon as you enter the car!

Factors Influencing Benzene Emissions from Passenger Car Refueling This report presents the results of an EPA test program designed to characterize benzene refueling emissions. It also examines several other available benzene refueling emission studies to form a combined data : Paul M.

12/83, Aug 9. The concentration of benzene, toluene, m -xylene and o -xylene in exhaust gases of Benzene emissions from passenger cars book cars and in city air were investigated. The mean emissions of aromatic compounds from 31 cars subjected to a total of ECE 15 test drives were: benzene ±toluene ±m -xylene ±95 and o -xylene 95± 40 mg km − by: Benzene emissions from a relevant proportion of today's gasoline-driven passenger cars and light-duty vehicles can increase by up to 2 orders of magnitude when driving at high engine load (e.g., on highways).
Under such conditions, post-catalyst benzene levels exceeded those found pre-catalyst. As a consequence, formation of benzene in the catalyst was by: One study measuring benzene levels inside parked cars with their engines turned off found more benign results.
Toxicologists took samples of the air inside both a new and a used vehicle under simulated hot-sunlight conditions, measuring the levels of volatile organic compounds (VOCs) including C3- and C4-alkylbenzenes, and exposing human and animal cells to the samples to. Benzene emission from the actual car fleet in relation to petrol composition in Denmark.
Supplementary manual traffic counts provided additional split-up of traffic in four vehicle categories: passenger cars, vans, trucks and buses. The passenger cars dominate the traffic with a diurnal variation obviously different from the other vehicle Cited by: General description.
Benzene (CAS Registry Number ; C 6 H 6; molecular weight g/mol) is an aromatic compound with a single six-member unsaturated carbon is a clear, colourless, volatile, highly flammable liquid with a characteristic odour and a density of kg/m 3 at 25 °C ().
At 1 atmosphere of pressure, benzene has a melting point of °C, a relatively low boiling Missing: passenger cars. People can be exposed to benzene in the environment from gasoline fumes, automobile exhaust, emissions from some factories, and waste water from certain industries.
Benzene is commonly found in air in both urban and rural areas, but the levels are usually very g: passenger cars. 3) Newly required recording of in-use durability 4) Until 12/ Diesel cars with GVW > 2 t and - a) > 6 seats or - b) off road vehicles were considered as N1 vehicles EURO - PASSENGER CARS M (≤ 2,5 T GVW, ≤ 6 SEATS).
Any benzene in the automobile compartment is from outside the car due to the emissions from petroleum products (leaks, tank venting, exhausts, etc.) and it is worse in the wintertime, not the summer.
This is because it has a tendency to condense/coalesce in the high-humidity passenger compartment when it comes in from outside. The in-use emissions from passenger cars exceed the new car standards mandated by law. Nonetheless, emissions continue to decrease in spite of high tampering rates and fuel switching (that is, using leaded fuel in engines developed to run on unleaded fuel).

Benzene is a harmful chemical that can exist both inside vehicles and in the open air but warnings such as this eRumor about airing out your car interior may be overblown.
The American Chemical Society released a report in saying that the interiors of motor vehicles were found to contain of a “wide variety of synthetic materials, which emit volatile organic compounds.”. According to research, the car dashboard, seats, air freshener emit Benzene, a Cancer causing toxin (carcinogen – take time to observe the smell of heated plastic in your car).
In addition to causing cancer, Benzene poisons your bones, causes anaemia and reduces white blood cells. Minimize emissions from vehicle exhausts by improved design and regular monitoring of engine settings. Separate dwelling spaces from areas where vehicles and benzene-containing products are kept.
In particular, isolate children from indoor exposure to vehicle emissions. Avoid domestic use of benzene-containing products. production or use of benzene as a feedstock) were identified as additional sources of benzene emissions: oil and gas wellheads, petroleum refineries, glycol dehydrators, gasoline marketing, publicly owned treatment works (POTWs), landfills, pulp and paperMissing: passenger cars.

In this study, the emissions from three passenger cars with gasoline, methanol, ethanol, and their blend were tested. The results show that the CO and HC emissions from the exhaust of the vehicles fueled with E/M decrease compared with those from the vehicles fueled with the gasoline, E10 or M15, while NO x emissions increase by –%.
