    Thailand, one of the world's largest sugarcane producers, has historically used organochlorine pesticides (OCPs) extensively in its plantations. Therefore, OCP residues are anticipated in plantation soil. However, the persistence of these compounds during sugar production is ambiguous. Thus, this study investigated the OCP residues in sugarcane at the different processing stages. Five product samples, i.e., sugarcane juice, bagasse, raw sugar, granulated white sugar, and molasses were obtained from different regions in Thailand. High concentrations of p,p′-dichlorodiphenyltrichloroethane (p,p′-DDT), γ-hexachlorocyclohexane (γ-HCH or lindane), and cyclodiene derivatives such as aldrin, dieldrin, heptachlor and its epoxide were found in the samples. This is surprising because the OCP use in sugarcane plantations has been long banned in Thailand. Bagasse and raw sugar had the highest total OCP concentrations of 1.0393 ± 0.7555 mg/kg and 0.9658 ± 0.8209 mg/kg, followed by white sugar (0.1616 ± 0.1311 mg/kg), molasses (0.0813 ± 0.1195 mg/kg), and sugarcane juice (0.0173 ± 0.0112 mg/kg). This study offers comprehensive information on the fate of OCPs during the entire sugarcane processing stage, from the cane to the final granulated sugar. The findings also suggest persistent OCP presence in plantation soil, possibly due to illegal use.

    This study aims to identify factors influencing individuals’ willingness to use mobile payment applications in China. Stimulus–organism–response (SOR) theory served as the foundational framework. Quantitative data were collected from 462 valid questionnaire addressing people’s use of mobile payment platforms in various regions of China. Structural Equation Modeling (SEM) results that perceived usefulness and ease of use significantly increase user satisfaction and perceived value. In the same vein, service quality and social influence also positively and significantly influence to satisfaction. In other words, cost has negative and significant impact on perceived value. Perceived value has positive and significant impact on satisfaction. Perceived value and satisfaction have positive and significant impact on willingness to use. The current study with significant findings contributed to fill the gap in the context of China region because only a few studies leveraged the SOR theory to explore mobile payment. The findings also contributed to enrich knowledge of mobile payment applications and provide actionable guidance to help mobile payment operators make strategic decisions. These results could also increase the understanding of mobile payment which paint a more vivid picture of this phenomenon and can enable mobile payment operators to make better strategic choices.
