Many people grow vegetables in their own garden, thinking that in this way they avoid the toxicity of the product on the market.
Many people grow vegetables in their own garden, thinking that in this way they avoid the toxicity of the product on the market. However, experts warn that this is not always the case. Scientists are trying to determine how much arsenic, lead, cadmium or pesticides remain in the soil.
Some time ago, the level of arsenic in food was monitored in Bangladesh, given that more than 40 million people were affected by water and food grown or cooked with it. Obviously, vegetables with edible roots, such as radishes, absorb more toxins than the leaves and fruits of others - spinach or tomatoes and zucchini, respectively. Until now, leafy vegetables were thought to be the largest accumulators of metals.
With the growth of cities, gardens are getting closer to former mining areas or industrial factories, etc., which pollute the soil with toxic substances. The study was aimed at determining in which part of the vegetables these substances accumulate. Experts point to the example of Australia, where arsenic has long been used as a pesticide and now, years later, the soil remains contaminated even in already populated areas.
