Electric cars release more toxic emissions than petrol-powered vehicles and are worse for the environment (msn.com)Interesting research...This doesn't mean that people should gravitate away from electric cars because they 'are more efficient depending zero emission,' Rakha said, but added the caveat that 'it also generates a lot of CO2 when charging your vehicle.'
EV batteries weigh about 453kg, and can result in tire emissions that are nearly 400 times more than exhaust pipe emissions.
Particle pollution can increase health problems including heart disease, asthma, lung disease and in extreme cases, can lead to hospitalisation, cancer, and premature death.
New petrol-powered cars are created to be 'cleaner,' by updating the trims of their internal combustion engines to include particulate filters that reduce emissions.
The EVs increased weight due to their lithium-ion batteries cause the tyre treads to wear faster, ultimately producing more emissions.
The study, conducted by the firm Emissions Analytics, said the main difference between exhaust pipe and tyre emissions is that the majority of particulate emissions released from the tyre go directly into the soil and water, while exhaust negatively affects the air quality.
The effects of tire composition come down to the materials the tyre is made from, the study reported.
Light-duty tyres are typically made from synthetic rubber which is developed using crude oil natural rubber adds fillers and additives, some of which are recognised carcinogens.
Emissions Analytics tested the tire wear on both EV and gas-powered vehicles after driving them at least 1,600km.
The researchers used a sampling system to collect particles immediately behind each tire and then measured the size of the particles emitted from the tread.
It found that the greater the vehicle's mass and weight, the more rapidly the tyre particulate emissions would be released due to the increased torque between the tires and the road.
