With the advent of transgenic, glyphosate-tolerant soybean and glufosinate-tolerant corn, this concern might be reduced by replacing some of the residual herbicides with short half-life, strongly sorbed, contact herbicides. |
In British soils, the apatites tend to be concentrated in the fine sand and silt and sorbed P and organic P in the clay fraction. |
Due to their hydrophobic nature, these contaminants are expected to be strongly sorbed to soil particles, hence not taken up by roots or translocated within plants to any significant extent. |
As higher-chain-length NPEs move through the treatment system, they are degraded to lower-chain-length NPEs and NPECs and ultimately to NP, which itself can be further degraded or sorbed to particles or sludges. |
The amount of TNT sorbed to soil was determined by subtracting the amount in aqueous phase from the amount initially added. |
The exchange of pesticide compounds between aqueous solution and the sorbed phase in soils is not instantaneous. |
