atr-ftir spectroscopy reveals polycyclic aromatic hydrocarbon contamination despite relatively pristine site characteristics: results of a field study in the niger delta.	fourier-transform infrared (ftir) spectroscopy is an emerging technique to detect biochemical alterations in biological tissues, particularly changes due to sub-lethal exposures to environmental contaminants. we have previously shown the potential of attenuated total reflection ftir (atr-ftir) spectroscopy to detect real-time exposure to contaminants in sentinel organisms as well as the potential to relate spectral alterations to the presence of specific environmental agents. in this study based ...	2017	26826366
novel sensor technologies towards environmental health monitoring in urban environments: a case study in the niger delta (nigeria).	the niger delta (nigeria) is an exemplar of a legacy of environmental pollution. limited knowledge on spatial and temporal pollutant distributions in the region highlights the need for biomonitoring approaches to study impacts on sentinel organisms. this study evaluated whether infrared (ir) spectroscopy and multivariate analysis could detect alterations in biomolecules in samples in differing exposure scenarios, i.e., spatial and temporal using african catfish (heterobranchus bidorsalis) or wat ...	2014	24602761
assessment of heavy-metal profile of the new calabar river and its impact on juvenile clarias gariepinus.	we have determined the heavy-metal status of the lower reaches of the new calabar river in the niger delta region over a 40-km-long distance, and its impact on the development of catfish (juvenile clarias gariepinus). the total mean concentrations of dissolved trace metals in the river were 0.01, 0.85, 0.56, 2.08, 0.05, 12.0, and 6.59 mg/l for hg, pb, cd, cu, cr, fe, and zn, respectively. the accumulated concentration of trace metals in the muscles of different mature fish caught from the river ...	2006	17193219
