Citizen scientist lepidopterists exposed to potential carcinogens

Area of Science:

• Entomology
• Occupational Health
• Environmental Science

Background:

• Lepidopterists, including many citizen scientists, utilize significant quantities of solvents for insect collection.
• Occupational healthcare often overlooks risks associated with solvent handling by non-professional researchers.

Purpose of the Study:

• To assess solvent usage, exposure risks, and safety practices among Finnish lepidopterists.
• To identify potential health risks linked to solvent exposure in entomological fieldwork.

Main Methods:

• Survey of Finnish lepidopterists regarding solvent use, exposure frequency, and safety precautions.
• Analysis of data on trap maintenance, catch handling, spill incidents, and self-reported adverse effects.

Main Results:

• Chloroform and 1,1,2,2-tetrachloroethane were common anaesthetics; exposure risks were highest during trap maintenance and sorting.
• Only 17% used adequate protection; spills were frequent, and exposure durations exceeded odour thresholds.
• Mild to moderate adverse effects were reported by 9.8% of participants, with no predictors of unsafe practices identified.

Conclusions:

• Lepidopterists face significant exposure risks from solvents used in insect trapping.
• Current safety practices are insufficient, highlighting a need for enhanced awareness and protective measures.
• Despite risks, adverse reactions were generally mild, but long-term effects remain a concern.
