The negatives of community gardens in urban areas - pollution

What is the effects of pollution on community gardens?

Urban areas have a lot of pollution, and this can be damaging for community gardens. Some people wonder if city-grown food is safe to eat because the soil in Urban areas can become toxic from harmful gases that come from vehicle exhausts or factories. Plants take in chemicals from the soil. They don't just absorb chemicals in their roots, but in their shoots, leaves, fruits and seeds. This means that people may eat those toxins. There’s little you can do to protect plants from this hazard, people are still learning about this issue. Some ways you can help to protect your garden is by using raised beds, and inspecting your soil regularly with the help of universities testing soil in their science labs.
