Objective: To understand the current status of malaria control knowledge awareness of primary and secondary school students and its influencing factors in Yunlong District, Xuzhou City, so as to provide the evidence for improving the malaria prevention work.
Methods: A total of 800 students from 4 urban and rural primary and secondary schools were randomly selected and investigated with questionnaires.
Results: The total awareness rate of malaria control knowledge was 61.
Article Synopsis
- This study looked at how two types of indoxacarb, a pesticide, break down in different soils.
- Researchers used X-ray technology to figure out the exact shapes of indoxacarb molecules.
- The results showed that in most soils, one type of indoxacarb broke down faster, but in some acidic soils, both types broke down equally, and bacteria were the main reason for these differences.
Article Synopsis
- This study examined how different types of soil affect the breakdown of the pesticide dufulin, focusing on its two enantiomers, S-(+)-dufulin and R-(-)-dufulin.
- The researchers used high-performance liquid chromatography (HPLC) to analyze the stability and degradation of these enantiomers, finding that they remained stable and did not convert into each other in nonsterile soil conditions.
- Results indicated that dufulin degraded faster in nonsterile soils due to microbial activity, with the S-(+)-enantiomer degrading more quickly than the R-(-)-enantiomer, suggesting that using S-(+)-dufulin could be less harmful to the environment.
