“…biochar into Chinese soils ( f om and percent clay were 0.012−0.046 and 12−56%, respectively) increased the Log K F of CAP from 0.18 to 2.29. 34,35 A significant increase in sorption was seen between 15 and 35 °C (P = 0.0326), while no significant change was observed between sorption at 25 °C and both 15 and 35 °C, consistent with previous observation that high temperature will enhance the sorption of organic compounds to rice field soils. 36 Therefore, the soil−water partitioning of CAP could be significantly impacted by early growing season temperature fluctuations, however, as the temperature stabilizes to daily fluctuations between 18−22 °C, it is not expected to impact the sorption of CAP to California rice field soils.…”

Chlorantraniliprole (3-bromo-N-[4-chloro-2-methyl-6-(methylcarbamoyl)phenyl]-1-(3-chloro-2-pyridine-2-yl)-1H-pyrazole-5-carboxamide, CAP; water solubility 1.023 mg·L) was recently registered for application on California rice fields. Air- and soil-water partitioning of CAP were investigated under simulated California rice field conditions through calculation of K and ΔH and a batch equilibrium method following OECD 106 guidelines, respectively. K and ΔH were determined to be 1.69 × 10 - 2.81 × 10 atm·m·mol (15-35 °C) and 103.68 kJ·mol, respectively. Log(K) ranged from 2.59 to 2.96 across all soil and temperature treatments. Log(K) ranged from 0.61 to 1.14 across all soil, temperature, and salinity treatments. Temperature and salinity increased sorption significantly at 35 °C (P < 0.05) and 0.2 M (P < 0.0001), respectively, while soil properties impacted sorption across all treatments. Overall results, corroborated using the Pesticides in Flooded Applications Model, indicate that volatilization of CAP is not a major route of dissipation and sorption of CAP to California rice field soils is moderately weak and reversible.

“…The resultant rice straw ash (RSA) is incorporated into the soil in the subsequent crop cultivation and may play an important role in the retention of pollutants in the soil. Previous studies have demonstrated that the incorporation of RSA and other burned crop residues into soils can enhance the adsorption capacity of the soils for organic contaminants, such as atrazine [16], diuron [17] and chlorophenol [18]. This enhanced adsorption capacity for organic contaminants is primarily attributed to the content of biochar comprising a range of materials from polyaromatic compounds to graphitic carbon [19][20][21][22][23].…”

“…The magnitudes of enhancement of freshly applied biochar on the sorption of hydrophobic organic matter in soils depend on the indigenous soil organic matter contents (Zhang et al 2010;Liu et al 2010). The proposed mechanisms were attributed to either competition for a limited capacity of environmental BC sorption sites between added organic substances and the native ones, or blocking of BC sites by soil dissolved organic matters (DOM) (Wen et al 2009 preloaded with humic acid (Koelmans et al 2009).…”

The sorption behavior of chlorantraniliprole (CAP) by biochar and effect of soil extracts on sorptivity in soil-biochar systems were examined. The results showed that biochar amendment could enhance the sorption of CAP in soils. The values of K F increased significantly when the soils were amended with 0.5 % BC850, which were from 1.54 to 196.5. The indigenous sorptivity of biochar was suppressed after it was applied to the soils. The degree of biochar sorptivity attenuation in different soil-biochar systems varied with the properties of soil water soluble matters. Sorption of CAP by biochar from the five soil extracts was found to be lower than that from a CaCl2 solution. The calculated K d values at C w of 0.01 mg kg(-1) for biochar sorption of CAP from CaCl2 solution were 21.4-26.6 times of that from soil extracts. Aging of biochar in soil extract reduced CAP sorption by up to 85 %.
