Effects of Electromagnetic Radiation and Radio Frequency on Freshwater Calanoid and Cyclopoid Copepods

(2024)
Method

Exposure Protocol EMF Exposure Conditions:

Voltages: 190 V and 230 VRF Frequency: 9 GHz

Exposure Durations: Varied (up to 300 minutes)

Control Group: Copepods not exposed to EMF/RF (baseline comparison)

Statistical Analysis

  • Data presented as mean ± standard deviation (e.g., 21.81 ± 3.14).

Likely used t-tests/ANOVA to compare exposed vs. control groups.

Result

Mortality Rates (after 300 min exposure):

  • Neodiaptomus sp. (Calanoid):
    190V: 21.81% ± 3.14
    230V: 34.55% ± 1.81
  • Mesocyclops sp. (Cyclopoid):
    190V: 18.18% ± 3.15
    230V: 21.21% ± 2.78

Biological Impacts:

Significant protein content alterations in both species

Observable changes in:

  • Sublethal exposure duration
  • Motility patterns
  • Amino acid composition

Species-Specific Sensitivity:

  • Calanoid copepods showed higher vulnerability
  • Voltage-dependent response observed (higher mortality at 230V)

Ecological Implications:

  • RF radiation (9GHz) and EMFs affect vital planktonic organisms
  • Potential disruption of aquatic food webs
  • Metabolic stress indicators detected

Conclusions:

  • Telecommunication EMF/RF emissions significantly impact copepod survival
  • Voltage intensity correlates with mortality rates
  • Protein-level changes suggest physiological stress mechanisms

Urgent need for further ecotoxicological assessments
