“…The changes appear to be a response to anthropogenic nitrogen deposition from agricultural and industrial sources to the east of the Rockies (Wolfe et al 2001(Wolfe et al , 2002(Wolfe et al , 2003Das et al 2005). The effects of recent human impact have also been demonstrated by a multi-proxy study of Upper Klamath Lake, USA (Bradbury et al 2004) and the impact of lake pollution and subsequent recovery were traced by Hynynen et al (2004). Human impact has also been studied in an archaeological context (Davies et al 2004).…”

Multi-proxy studies are becoming increasingly common in palaeolimnology. Eight basic requirements and challenges for a multi-proxy study are outlined in this essay -definition of research questions, leadership, site selection and coring, data storage, chronology, presentation of results, numerical tools and data interpretation. The nature of proxy data is discussed in terms of physical proxies and biotic proxies. Loss-on-ignition changes and the use of transfer functions are reviewed as examples of problems in the interpretation of data from multi-proxy studies. The importance of pollen analysis and plant macrofossil analysis in multi-proxy studies is emphasised as lake history cannot be interpreted without knowledge of catchment history. Future directions are outlined about how multi-proxy studies can contribute to understanding biotic responses to environmental change.

“…In addition, sediments are contaminated during previous decades and pose a risk if they act as a source of contaminants due to re-suspension (Rämänen et al 2010). For example, previously untreated effluent with wood-derived bioactive substances and heavy nutrient load released into natural waters cause oxygen depletion and decline of diversity of species (Hynynen et al 2004).…”

“…It has been demonstrated that Exploratory Data Analysis (EDA) is the best approach to identify chemical tracer or specific chemical fingerprints which could be associated to suspected sources for assessing cause-effect relationships 5 . Chemical fingerprints and chemical tracers have been successfully used to distinguish discrete fuel types 6,7,8 , fecal sterols sewage contamination 9,10 , particular solvents used as vapor degreasers, PCBs for age dating and source identification 7 and Kraft pulp bleaching activities 11 . Oil fingerprinting as identification system is based on the analysis of chemical profile of even and odd carbon number distribution of aliphatic hydrocarbons that reflect the source of contamination and the weathering stage of the pollutant.…”

Sediments and mussel specimens of Mytilus chilensis were analyzed for organic pollutant fingerprints and heavy metals in the Corral Bay area of Valdivia, South Central Chile during the period [2003][2004]. GC-MS analysis show hydrocarbon fingerprints corresponding mainly to mixed inputs of aliphatic hydrocarbons of the TPH-diesel fraction and biogenic hydrocarbons, indicating low to medium contamination by petroleum hydrocarbons with high biodegradation of petroleum in sediments at Las Coloradas, La Escuela and Corral Bay (C 17 /Pri < 1 and C 18 /Phy < 1). Mussel TPH fingerprints show weathered hydrocarbons resulting in a zone of increased concentration of cyclic respect to acyclic aliphatic components (UCM), indicating the presence of petroleum hydrocarbons. No temporal variation the in concentration of TPH-diesel found in sediments as well as mussels were observed except for samples collected during January 2004. TPH concentration levels in the sediments varied from 0.4 µgg -1 to 33.8 µgg -1 d.w. whereas in mussels varied between 61 µg g -1 and 287 µgg -1 d.w. Heavy metals were also analyzed by atomic absorption spectrometry and low concentration as well as no seasonal variations of concentration were found in mussels at each sampling point and a relatively even distribution of metals among stations was observed. Maximum concentrations in all sampling points of sediments were found for Fe (24128-43791 µgg -1 ) and Mn (181-388 µgg -1 ) while the minimum concentration was found for Pb (nd-12 µgg). According to the Sediment Quality Guidelines (SQGs-NOAA), the concentration levels of Cu and As in all sediment sampling points are above the "Effects Range-Low" (ERL), indicating that there may be a probable toxicity effect over the biota and attention must be paid on a moderate range of priority.
