What is bioaccumulation?

Bioaccumulation is when something harmful stays inside your body and gets bigger over time.

Imagine you're eating candy every day, but instead of sweet stuff, it's tiny bits of something not so nice. At first, it doesn’t seem like much, but after a while, all those little pieces add up, and they start to make you feel not so good.

Think of your body like a sponge in the ocean. The sponge is soaking up water, just like your body is soaking up tiny bits of something from food or drink. At first, it’s only a little bit, but if the sponge keeps absorbing more and more, eventually it becomes full, or even too full.

That's what happens with bioaccumulation: your body keeps taking in small amounts of something harmful over time, like a sponge soaking up water, until there's enough to cause problems.

It’s not magic, it’s just something that builds up slowly, day by day, like eating one piece of candy every day without even noticing it.
