## Introdução

The accurate determination of pesticide residues in food and environmental samples is crucial for ensuring public health and environmental safety. Triazine pesticides, a class of herbicides widely used in agriculture, are of particular concern due to their persistence and potential ecological and health risks. This article focuses on the development of an efficient triazine pesticide standards mix, which serves as a vital tool for accurate testing solutions in pesticide residue analysis.

## Importance of Accurate Testing

Accurate testing of pesticide residues is essential for several reasons. Firstly, it helps in monitoring compliance with regulatory standards, ensuring that food products meet safety thresholds. Secondly, it aids in identifying sources of contamination and implementing appropriate control measures. Lastly, accurate testing is vital for the protection of public health and the environment, as it helps in preventing the accumulation of harmful substances in ecosystems.

## Composition of the Standards Mix

The triazine pesticide standards mix is a carefully formulated mixture of known concentrations of various triazine pesticides. The composition of the mix includes commonly detected triazine pesticides such as atrazine, simazine, and propazine. The choice of these compounds is based on their widespread use in agriculture and their potential for contamination in food and environmental samples.

### Table 1: Composition of the Triazine Pesticide Standards Mix

| Pesticide | Concentration (µg/mL) |
|-----------|-----------------------|
| Atrazine | 50, 100, 200 |
| Simazine | 50, 100, 200 |
| Propazine | 50, 100, 200 |

## Performance in Analytical Methods

The triazine pesticide standards mix has been evaluated in various analytical methods, including gas chromatography (GC), liquid chromatography (LC), and high-performance liquid chromatography (HPLC). The results demonstrate the mix's effectiveness in enhancing the accuracy and precision of pesticide residue analysis.

### Cromatografia em fase gasosa (GC)

GC is a widely used technique for the analysis of volatile organic compounds, including triazine pesticides. The standards mix has been successfully applied in GC, showing good linearity and recovery rates. The use of the mix as an internal standard has minimized matrix effects and improved the accuracy of the results.

### Liquid Chromatography (LC)

LC is another commonly employed method for the analysis of non-volatile organic compounds. The triazine pesticide standards mix has been effectively utilized in LC, providing reliable results with high sensitivity and selectivity. The mix has been instrumental in detecting low levels of triazine pesticides in complex matrices, such as food and environmental samples.

## Benefits for Regulatory Agencies and Researchers

The efficient triazine pesticide standards mix offers several benefits for regulatory agencies and researchers. Firstly, it facilitates the development of standardized testing protocols, ensuring consistency in the analysis of pesticide residues. Secondly, the mix aids in the training of laboratory personnel, enhancing their proficiency in pesticide residue analysis. Lastly, the mix provides a valuable tool for researchers in studying the behavior and fate of triazine pesticides in the environment.

## Conclusão

In conclusion, the efficient triazine pesticide standards mix is a valuable tool for accurate testing solutions in pesticide residue analysis. Its development and application have significantly improved the precision and reliability of pesticide residue analysis in food and environmental samples. The mix's performance in various analytical methods and its potential benefits for regulatory agencies and researchers highlight its importance in ensuring public health and environmental safety.
