For example, many agricultural researchers are doing studies of the relationship between heavy metals and vegetables to understand the degree of tolerance of each variety toward contaminants. Is there some special structure or resistance in the plants that do not readily absorb and attach metals?
例如許多農業人員開始對重金屬與蔬菜關係進行研究，瞭解不同品種間對汙染物的忍耐度；不易吸附重金屬的作物體內，是否有特別的機制，可以抑制重金屬往上吸收。
