Bromide residues in lettuce after soil fumigation with methyl bromide, and some factors involved

Iodine, bromine and chlorine contents in solls and plants of Japan

“…From the iodine and bromine contents shown in Table I (Forest soil) and 3 (Paddy soil), it appears that there was a similar difference between the values in the paddy soil (Site No. 16,21,23) and those of the forest soil (Site No. 15,20,22) having the same parent rock as that of the neighboring paddy soil.…”

The occurrence of bromine in some Finnish and imported vegetables determined by a polarographic method

“…Table 2 shows that the lettuce samples originating from Holland and Spain (1 sample) had the highest bromide contents. These are obviously due to the bromide treatment of the soil, since the mean bromide content of lettuce grown on untreated soil, according to Stark and Suss (1973), is 1.16 ppm, and bromide is known to accumulate in lettuce ( Van Wambeke 1974).…”
