“…Perfluoroalkyl acids (PFAAs) are a group of synthetic perfluorinated compounds that have been extensively used in the fabric, paper, electronics, and many other industries since the end of the twentieth century [1][2][3]. However, they are listed as persistent organic pollutants (POPs) by the Stockholm Convention owing to their high stability, bioaccumulation factor, and the potential toxicity of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in humans and wildlife [4][5][6][7][8][9][10][11]. PFOA and PFOS released from different products into the environment contaminate the air, soil, and water, and can remain in the environment for over a decade [6,[12][13][14][15].…”

Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) are persistent organic pollutants (POPs) that are prohibited from being produced and used. However, they remain in the agricultural environment and are transferred to crops. In addition, PFOA is classified as possibly carcinogenic to humans. To fully understand the exposure and risk of PFOA and PFOS for human in crops, a residue survey and estimation of dietary exposure assessment are needed. Therefore, we investigated the residues of PFOA and PFOS in upland soil and cultivated root crops. The average residues of PFOA and PFOS in the soil were < 0.054–0.541 μg kg–1 and 0.024–0.111 μg kg–1, and 0.067–0.193 μg kg–1 and < 0.02 μg kg–1 in the crops, respectively. The average PFOA residues were higher than PFOS in the soil and crops. The estimated daily intakes of PFOA and PFOS in the crops were 0.284 ng kgbw–1 day–1 and 0.023 ng kgbw–1 day–1, and the estimated hazard quotients were 0.355 and 0.013, respectively. In addition, the excess cancer risk of PFOA was calculated to be 1.99 × 10–8. Thus, the non–carcinogenic and carcinogenic risks of PFOA and PFOS were not notable from the surveyed residues in the crops. However, the risks may be higher when the residues in other food crops are considered.

“…The Stockholm Convention has classified endosulfan as a persistent organic pollutant (POPs) due to its persistence, long-range transport, and high bioaccumulation properties Choi et al, 2021;Sathishkumar et al, 2021). Most countries have banned the production and use of endosulfan a decade ago, however, it is still frequently detected in the air, water, and soil environment (Oh et al, 2020;Bruce-Vanderpuije et al, 2021). The reported 50% dissipation time (DT50) in soil is 4 to 75 days, 4 to 376 days, 26 to 200 days, and 6 to >200 days for α-endosulfan, β-endosulfan, endosulfan sulfate, and total endosulfan, respectively (Ntow et al, 2007;Weber et al, 2010;Vaikosen et al, 2019).…”

Although the underlying reasons behind the wide ranges of the DT50 in soil are unclear, the reason was believed to be the leaching potential and varying microbial degradation activity in different soils and crop cultivation practices (Ghadiri et al, 2001;Grondona et al, 2014;Oh et al, 2020;Singh and Singh 2008). Among the crop cultivation practices, tillage and mulching are directly affected to the soil condition.…”

“…These values are comparatively lower than BAFs in animals, such as 2628-3278 in plankton, 2429-11583 in fish, and 0.53-2.62 in chickens (Brinati et al, 2016;DeLorenzo et al, 2002;Fang et al, 2018;Negro et al, 2012;Sathishkumar et al, 2021;Toledo and Jonsson 1992).

Endosulfan was widely used as an insecticide in the agricultural sector before its environmental persistence was fully understood. Although its fate and transport in the environment have been studied, the effects of historic endosulfan residues in soil and its bioaccumulation in crops are not well understood. This knowledge gap was addressed by investigating the dissipation and bioaccumulation of endosulfan in ginseng as a perennial crop in fresh and aged endosulfancontaminated fields. In addition, the effect of granular biochar (GBC) treatment on the bioaccumulation factor (BAF) of endosulfan residue in ginseng was assessed. The 50% dissipation time (DT50) of the total endosulfan was over 770 days in both the fresh and aged soils under mulching conditions.; This was at least 2-fold greater than the reported (6->200 days) in arable soil. Among the endosulfan congeners, the main contributor to the soil residue was endosulfan sulfate, as observed from 150 days after treatment. The BAF for the 2-year-old ginseng was similar in the fresh (1.682-2.055) and aged (1.372-2.570) soils, whereas the BAF for the 3-year-old ginseng in the aged soil (1.087-1.137) was lower than that in the fresh soil (1.771-2.387). The treatment with 0.3 wt% GBC extended the DT50 of endosulfan in soil; however, this could successfully suppress endosulfan uptake, and reduced the BAFs by 66.5-67.7% in the freshly contaminated soil and 32.3-41.4% in the aged soil. Thus, this adsorbent treatment could be an effective, financially viable and sustainable option to protect human health by reducing plant uptake of endosulfan from contaminated soils.

Pesticides are indispensable tools in modern agriculture for enhancing crop productivity. However, the inherent toxicity of pesticides raises significant concerns regarding human exposure, particularly among agricultural workers. This study investigated the exposure and associated risks of two commonly used pesticides in open-field pepper cultivation, namely, chlorothalonil and flubendiamide, in the Republic of Korea. We used a comprehensive approach, encompassing dermal and inhalation exposure measurements in agricultural workers during two critical scenarios: mixing/loading and application. Results revealed that during mixing/loading, dermal exposure to chlorothalonil was 3.33 mg (0.0002% of the total active ingredient [a.i.]), while flubendiamide exposure amounted to 0.173 mg (0.0001% of the a.i.). Conversely, dermal exposure increased significantly during application to 648 mg (chlorothalonil) and 93.1 mg (flubendiamide), representing 0.037% and 0.065% of the total a.i., respectively. Inhalation exposure was also evident, with chlorothalonil and flubendiamide exposure levels varying across scenarios. Notably, the risk assessment using the Risk Index (RI) indicated acceptable risk of exposure during mixing/loading but raised concerns during application, where all RIs exceeded 1, signifying potential risk. We suggest implementing additional personal protective equipment (PPE) during pesticide application, such as gowns and lower-body PPE, to mitigate these risks.
