Organophosphorus Pesticide Residues in Sapodilla Fruit via GC-MS

Chlorpyrifos was detected in about 70% of fruit and 33% of pulp samples from commercial sapodilla, despite being prohibited by ANVISA and EC guidelines. The dataset likely contains measurements for eight pesticides, including dichlorvos and parathion methyl, validated using a QuEChERS extraction and GC-MS detection method. Good linearity (R > 0.99) was obtained, with detection limits ranging from 0.01 to 0.06 mg kg-1.

Use Cases

• Validate pesticide detection methods based on the described QuEChERS extraction and GC-MS protocol.
• Assess compliance with food safety regulations based on the detection of prohibited pesticides like chlorpyrifos.
• Study matrix effects in analytical chemistry based on the described need for matrix-matched calibration.
• Analyze recovery rates for pesticide analysis based on results between 70 and 120% with RSD < 20%.

Strengths

• Method validation shows good linearity with R > 0.99 for all eight pesticides studied.
• Recovery studies at six different levels (0.08 to 1.17 mg kg-1) showed results between 70 and 120% with RSD < 20%.
• Limits of detection and quantification are provided, ranging from 0.01 to 0.06 mg kg-1 and 0.03 to 0.2 mg kg-1, respectively.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
