Title : Cellular phone radiation and its impact on chlorophyll content of some selected plant species and bird nesting in Aligarh, Uttar Pradesh, India
Abstract:
The electromagnetic radiation (EMR) spectrum is an essential component of daily life, originating from natural sources such as solar radiation and human-made sources including electricity, medical devices, and mobile communication systems. EMR ranges from highenergy ionizing radiation to low-energy non-ionizing radiation and underpins technologies such as telecommunications, medical imaging, and photosynthesis research. Increasing reliance on mobile technologies has intensified concerns about electromagnetic field (EMF) exposure and its potential effects on humans, animals, and plants. In India, despite rapid growth in mobile usage, field-based studies on EMF impacts across diverse biological taxa remain limited, and regulatory guidelines largely focus on human safety. Inconsistencies in research methodologies further hinder clear conclusions. This study highlights these gaps while reporting experimental evidence on plants: exposure to 900 MHz EMF resulted in reduced chlorophyll content with increasing radiation intensity. Maximum chlorophyll (44.04 µmol/m²) occurred under low radiation, while minimum levels (34.52 µmol/m²) were observed under moderate radiation. One-way ANOVA indicated significant differences among radiation treatments (F? = 33.63, P < 0.01), emphasizing the need for standardized, ecosystem-focused EMF research.
