Summary: This study demonstrated the direct monitoring of chromium and copper contamination in algae on a filter using LIBS, showing that LIBS is capable of accurately detecting such contamination and providing information comparable to ICP-MS. The results suggest that LIBS could be an alternative to ICP-MS for monitoring the growth inhibition of algae depending on chromium or copper content.

Summary: The contamination of algae with chromium and copper on a filter can be directly monitored using LIBS, which provides comparable sensitivity and almost equivalent information to ICP-MS. The trend obtained from LIBS analysis was more similar to that of LA-ICP-MS, indicating that LIBS can be an alternative method to monitor the inhibition of algae growth caused by chromium or copper without the need for the complicated decomposition procedure in ICP-MS analysis.

Summary: Laser ablation inductively coupled plasma mass spectrometry is a powerful technique for trace element analysis of solid samples, but its full quantitative capability is limited by the complex relationships between various factors. Altering laser ablation conditions can effectively change the physicochemical properties of LA-generated particles and improve the understanding of their impact on corresponding ICPMS signals. This multidimensional particle characterization approach can comprehensively study LA-generated particles and their effects on ICPMS signals, with potential for extension to other samples and laser wavelengths.

Summary: In this study, LA-ICP-MS was used to quantitatively analyze 46 trace elements in USGS samples. The results showed that the matrix effect had an impact on the analysis accuracy, with refractory elements being underestimated. Additionally, the laser sampling from different matrix samples directly determined the final analysis accuracy.

Summary: Advanced data processing and visualization techniques were applied to analyze the uptake and transformation of ionic silver to silver nanoparticles in sunflower roots, revealing that the size of the biosynthesized AgNPs is predisposed by the reducing power of specific root compartments. This multimodality information can only be obtained by combining the results of techniques from several complementary platforms.

Summary: Hair and nails are increasingly being used in human biomonitoring due to their non-invasive sampling, stability, and ease of storage. However, the lack of standardized analytical protocols has hindered the use of laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) for elemental analysis of these samples. In this study, analytical methods were developed for the analysis of model elements in hair and nails using LA-ICP-MS. Critical aspects of the method, such as line scan vs. spot scan and sample cleaning, were evaluated. The study demonstrates the potential application of LA-ICP-MS in high throughput elemental analysis of hair and nail samples for future biomonitoring studies.

Summary: Laser-induced breakdown spectroscopy (LIBS) has been utilized for estimating soil carbon content by detecting atomic carbon lines, with a challenge being interference from iron lines. By using a high-resolution spectrometer, suitable emission lines near 247.8561 nm can be identified to minimize overestimation of carbon content in soil samples. This method reduces the impact of interference, soil heterogeneity, and matrix effects, showing potential for quantifying soil carbon accurately.

Summary: The study found that three techniques (refractive index, mu XRF, and LIBS) had high correct association rates for samples originating from the same source in forensic glass sample comparisons. Similarly, there were high correct exclusion rates for samples from different vehicles. Significant variations in reported conclusions between laboratories were observed, highlighting the need for standardization of reporting language.
