| Abstract | The purpose of this study was to assess the toxicological effects of two munition compounds, 4-amino-2,6-dinitrotoluene (4A-DNT) and 1,3,5-trinitro-1,3,5-triazine (RDX), on three different bird species: two common toxicological model species—the Northern Bobwhite (Colinus virginianus) and the Japanese Quail (Coturnix japonica), and a representative passerine—the Zebra Finch (Taeniopygia guttata). Bobwhite were exposed to 4A-DNT at 0, 8, 15, 30, 60, or 150 mg/kg body weight (bw) d by oral gavage for seven days; because the high dose of 4A-DNT was lethal to bobwhite, the maximum dose was changed to 100 mg/kg bw d for Japanese quail and finches to ensure tissue could be used for future toxicogenomic work. RDX was similarly administered at 0, 0.5, 1.5, 3, 6, or 12 mg/kg bw d. Blood was drawn prior to euthanasia for blood cellularity and chemistry analyses. Finches were clearly least affected by 4A-DNT as evidenced by a lack of observable effects. Bobwhite appeared to be the most sensitive species to 4A-DNT as observed through changes in blood cellularity and plasma chemistry effects. Bobwhite appeared to be more sensitive to RDX than Japanese Quail due to increased effects on measures of plasma chemistries. Finches exhibited the greatest sensitivity to RDX through increased mortality and seizure activity. This study suggests that sensitivity among species is chemical-specific and provides data that could be used to refine current avian sensitivity models used in ecological risk assessments. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
