Accumulation of Major and Trace Elements in Spider Webs

Area of Science:

• Environmental Science
• Ecotoxicology
• Analytical Chemistry

Background:

• Air quality monitoring is crucial for urban health.
• Biomonitoring using biological indicators offers a cost-effective approach.
• Spider webs can accumulate airborne pollutants.

Purpose of the Study:

• To evaluate heavy metal and trace element contamination in Wrocław's air.
• To investigate the potential of Malthonica ferruginea spider webs as biomonitors.
• To identify sources of airborne pollution in urban and industrial areas.

Main Methods:

• Collection of Malthonica ferruginea webs from diverse urban locations over 60 days.
• Quantification of 16 major and trace elements using analytical techniques.
• Statistical analysis including Principle Component Analysis (PCA) and correlation analysis.

Main Results:

• Spider webs from high traffic and postindustrial sites showed elevated element concentrations.
• Residential and low-traffic urban sites exhibited lower pollutant levels.
• PCA and correlation analysis identified road traffic and industrial activities as primary contamination sources.

Conclusions:

• Malthonica ferruginea webs are effective biomonitors for assessing airborne element distribution.
• Spider webs can reveal localized pollution patterns within a city.
• This study provides baseline data for urban air quality assessment in Wrocław.
