Case Report
Problems with Hawaiian Forest Birds

Leonard A. Freed, Rebecca L. Cann

We have documented that the introduced Japanese white-eye (Zosterops japonicus) has outcompeted an entire community of native birds at Hakalau Forest National Wildlife Refuge. We estimate that the refuge has lost an average of 31.5% of individuals of its eight native passerine species in a 3373 ha area to competition, and up to 50% of one endangered species. While we believe that the white-eye needs to be controlled, the USGS-BRD still asserts that native bird populations are stable.

Radiation Induced OH Free Radicals Degradation Process of Phenol in Aqueous Solutions – Environmental Implications

Fathi Djouider*

The presence of the phenol, an organic refractory pollutant, in wastewater is one of the biggest environmental issues for both human health and life in aquatic ecosystems. In this study, gamma radiation induced degradation of phenol has been investigated. The radiolitically produced hydroxyl free radical OH initiates the degradation via its addition to the phenol ring. After one hour, the phenol degradation was found 98% at a dose of 9 kGy.

Climate Change and the Rise of Obesity

LisaAnn S Gittner*, Barbara Kilbourne, Katy Kilbourne, Youngwon Chun

In the late 20th century, temperatures in cities have increased significantly faster as compared to rural areas. Research shows during extreme heat events, both morbidity and mortality increase and correspond to physiologic changes rendering individuals sensitive to the heat. In addition, the climate has also been changing over the same time period.

Factors Affecting the Biosorption of 2-Chlorophenol Using Spent Tea Leaf Wastes as Adsorbent

Tenzing Japhe, Kateryna Zhdanova, Lisa Rodenburg, Loretta Roberson, Abel E. Navarro*

The presence of phenolic compounds is often underestimated in environmental protection. However, the combination of their prevalence in industrial runoffs and negative impact in human health and ecology is a top-priority concern. Chamomile (CM), green tea (GT) and peppermint (PM) spent tea leaves were used as potential adsorbents of 2-chlorophenol (2-CP) from aqueous solutions in batch conditions at room temperature. Equilibrium parameters such as pH and adsorbent dose were studied to maximize the uptake of 2-CP. Moreover, the effect of interfering inorganic and organic substances on the adsorption was studied. Results indicate that the adsorption of 2-CP is strongly affected by the pH, showing its lowest and highest values at pH 6 (21%) and pH 9 (90%) for CM.
