Bioconcentration is usually used in reference to pollutants. When you spray plants with herbicides and pesticides, some gets taken up into their tissues. When animals eat these plants, they also eat the pesticides and herbicides. The majority of these chemicals are fat-soluble and will accumulate in fat. Since vegetables are naturally low in fat, when you buy organic vegetables, you are only avoiding a little bit of poison. When you buy organic meat, especially the fatty cuts, you’re avoiding a lot.
