Plants that are infected must be destroyed as the disease can be transmitted from plant to plant by contaminated sap. Symptoms include dark green ink bleed marks in the veins of yellow-colored leaves, and/or tissue collapse between veins.
Exposure to EMF and cancer. Magnetic fields are classified by the International Agency for Research on Cancer (IARC) as a possible cause of cancer, particularly for childhood leukemia. However, experts agree that there may be other explanations for the potential link between exposure to EMF and childhood leukemia. Until scientific evidence can clarify the link between exposure to magnetic fields from high-voltage power lines and cancer risk, you may not want your children to play directly beneath them for long periods of time.
This analysis showed that higher levels of exposure to magnetic fields, as measured by the monitors, were associated with 4 1/2 times the risk of leukemia, and confirmed the increased risk in children under 6 and for acute lymphoblastic leukemia.his analysis also looked at electric fields, which, unlike magnetic fields, were associated with a decreased leukemia risk. Both analyses showed no association between living close to high-tension power lines and leukemia risk overall.
