“…The comparatively higher removal of endosulfan sulfate in the presence of i-PrOH suggested the primary role of e aq À in the removal of endosulfan sulfate. The result was consistent with the findings by Al-sheikhly et al (1997) and Guo et al (2009) showing the removal of halogenated compounds, such as 2,6-dichlorobiphenyl and halomethanes from aqueous solution by gamma irradiation was primarily due to e aq À . The second-order rate constant of endosulfan sulfate with Å OH and e aq À was determined by competition kinetic method as described above in experimental section and was found to be 8.1 Â 10 9 and 3.4 Â 10 10 M À1 s À1 , respectively.…”

“…During the partial solar eclipse of October 1995, we have detected huge gamma counts at the eclipse maximum by gamma ray spectrometric experiments with NaI (Tl) scintillator. Since our measurements show drastic decrease in pH value of seawater during both the total eclipse event (partial at study location) on 22 July 2009 and the annular solar eclipse on 15 January 2010, when exposed to solar radiation, in view of the report of Zhaobing et al [25], the reduction in pH value is due to the shorter wavelength radiations reaching the surface of the earth. By comparing our earlier detection and measurements with the report of Zhaobing et al [25], it is obvious that among the shorter waves, gamma rays influences more in the reduction of pH value in seawater.…”

Eclipse induced changes in solar radiation is a common interest of scientists all over the world. The disturbance of the heat balance along the supersonic travel of the trajectory of the Moon's shadow could generate gravity waves during solar eclipse, which results a reduction in the concentration of ozone layer in the stratosphere. We, in this context, conducted some experiments to detect the possible radiations reaching the surface of the earth and the impact of such radiation in seawater during the recent total and annular solar eclipses. This is the first time that the variation in pH value of seawater during solar eclipse is examined, and the experimental data demonstrated that the solar eclipse phenomenon affects the pH value of seawater due to the shorter wavelength radiations received on the surface of the earth. The reduction is around 20% and 40% of the difference between ordinary water and seawater during total and annular eclipses respectively. The multidisciplinary influences of these findings are addressed.

Remediation of wastewater, sludge and removal of objectionable substances from our environment using radiation technology is neglected. Hardly, a couple of decades ago, application of electron beam (EB) technology has gained attention for waste management. When wastewater is irradiated with electron beam, the beam can alter the physico-chemical properties of irradiated aqueous material and also transform wastewater chemicals due to the excitation or ionization of chemical molecules. Thus, chemical reactions may be capable of producing new compounds. The beam of electrons initiates primary reactions to induce the excitation or ionization of molecules at varied rates. This review paper will help to a budding researcher how to optimize the irradiation process to achieve high efficiency with low electron beam energy which is economically viable/ feasible. Application of E-beam radiation for wastewater treatment may ensure future smart cities with sustainable water resources management.
