Fewer house sparrow males were observed at locations with higher electric field strength from GSM base stations.

Plain English Summary

Summary written for general audiences

Researchers studied the effect of long-term exposure to low-intensity electromagnetic radiation from GSM base stations on house sparrows during breeding season in six Belgian residential districts. They sampled 150 point locations across the six areas to examine variation in male house sparrow numbers and electromagnetic radiation strength. The number of male house sparrows was negatively and highly significantly related to electric field strength from 900 and 1800 MHz downlink bands. This negative relationship was consistent across all six study areas despite differences in bird numbers and radiation levels.

Why This Matters

The researchers concluded that their data support the notion that long-term exposure to higher radiation levels negatively affects house sparrow abundance or behavior in the wild. They found fewer male house sparrows at locations with relatively high electric field strength from GSM base stations.

Quick Questions About This Study

The study investigated the effect of long-term exposure to low-intensity electromagnetic radiation from GSM base stations on house sparrow numbers during breeding season in six Belgian residential districts.
The researchers sampled 150 point locations across six residential districts in Belgium.
The number of male house sparrows was negatively and highly significantly related to electric field strength from both 900 and 1800 MHz downlink frequency bands.
The negative relationship was highly similar within each of the six study areas despite differences in bird numbers and radiation levels.
The researchers concluded that fewer male house sparrows were seen at locations with higher electric field strength from GSM base stations, supporting the notion that long-term exposure to higher radiation levels negatively affects sparrow abundance or behavior in the wild.
