Air Pollution

A person stands next to a white electric vehicle while it charges at a public charging station. The car is backed into a spot marked "CHARGING ONLY," and the charging cable extends from the station to the car’s rear. The person wears a dark jacket, pants, and orange sneakers, and looks down toward the ground. Bright sunlight casts distinct shadows on the pavement.

These communities are unaware they’ve lived near toxic gas for decades. Why has no action been taken?

Five facilities near schools and houses in LA County fumigate produce shipped from overseas with methyl bromide. But the air agency doesn’t plan to monitor the air or take any immediate steps to protect people from the gas, which can damage lungs and cause neurological effects.

A busy shipping port with large, blue gantry cranes labeled 'YTI' towering over stacks of colorful shipping containers. The cranes are equipped with yellow lifting mechanisms used for moving cargo. The sky is clear blue with a few wispy clouds. Rows of containers in shades of red, pink, blue, and brown are stacked neatly along the port, some marked with shipping company names such as 'ONE' and 'CAI.'

‘Herculean effort’: These port communities have waited decades for clean air. Why a new plan may fall short

The ports of LA and Long Beach are the biggest sources of air pollution in the LA basin. Air quality officials have drafted new rules to help electrify the ports. But community groups representing 400,000 residents say they don't go far enough or fast enough to clean up their dirty air.
