| Abstract | Chemical ultraviolet (UV) filters are used in various products and could be released into the environment, for example, via sunscreens used at swimming lakes. UV filters have been found in surface waters in the past but only a few investigations have concentrated on the effects of these substances in the environment. This study investigates the effects of a UV filter in the amphipod Gammarus fossarum at the cellular and molecular level. Stress protein (Hsp70) responses and reactions of hepatopancreatic cells and cells of gut appendices were investigated in the freshwater amphipod Gammarus fossarum after short-term exposure (4 days) to five different concentrations of the UV filter 3-benzylidene camphor (3-BC; 33 ng/L, 330 ng/L, 3.3 μg/L, 33 μg/L, 330 μg/L) and two control conditions (water and solvent ethanol). Male as well as female gammarids showed increased Hsp70 levels after exposure to low concentrations of 3-BC, with a maximum response at 3.3 μg/L, while the higher concentrations resulted in lower Hsp70 levels. This effect was most likely due to a cessation of Hsp70 synthesis following pathological impact as indicated by strong cellular responses and cellular damage obtained in epithelia of the hepatopancreas and the gut appendices after treatment with 330 μg/L 3-BC. Although environmentally relevant concentrations of 3-BC did not seem to have an adverse effect in this short-term study, higher concentrations of 3-BC are surely detrimental. It is known that chronic exposure generally requires much lower concentrations to cause harm than acute exposure. Additionally, juvenile stages may be even more sensitive than the adults tested. Therefore, on the basis of this study, 3-BC-effects in the field cannot be excluded and should be regarded possible. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
