Multivariate statistical evaluation of dissolved trace elements and a water quality assessment in the middle reaches of Huaihe River, Anhui, China
TLDR
The results of the water quality index (WQI) indicate that water in the Huaihe River is heavily polluted by trace elements, so approximately 96% of the river water is unsuitable for drinking and a health risk assessment suggests that Co, Cd and Pb in the river could cause non-carcinogenic harm to human health.About:

Multivariate statistical methods and GIS based evaluation of the health risk potential and water quality due to arsenic pollution in the Kızılırmak River
TL;DR: In this paper , the spatial distribution, effect on irrigation water quality, environmental pollution status, ecotoxicological and health risks as well as possible sources of 12 potential toxic elements' (PTEs) (manganese (Mn), aluminum (Al), arsenic (As), chromium (Cr), zinc (Zn), iron (Fe), nickel (Ni), cadmium (Cd), cobalt (Co), copper (Cu), mercury (Hg), and lead (Pb)) concentrations from surface water samples in the Kızılırmak River were analyzed by using geographical information systems (GIS) software and multivariate statistical analysis.

Potentially toxic elemental contamination in Wainivesi River, Fiji impacted by gold-mining activities using chemometric tools and SOM analysis
Satendra Kumar,A.G. Tashlinskiy +1 more
TL;DR: In this paper , an integrated approach of self-organizing map (SOM), principle component analysis (PCA), hierarchical cluster analysis (HCA), and indexical approaches was used to evaluate the spatial pattern, eco-environmental pollution, and source apportionment of potentially toxic element (PTE) contamination in Wainivesi River, Fiji triggered by gold-mining activities.

Application of factor analysis in the assessment of groundwater quality in a blackfoot disease area in Taiwan
TL;DR: The over-extraction of groundwater is the major cause of groundwater salinization and arsenic pollution in the coastal area of Yun-Lin, Taiwan and this model explains over 77.8% of the total groundwater quality variation.

Assessment of seasonal and polluting effects on the quality of river water by exploratory data analysis
TL;DR: In this article, an ANOVA of the rotated principal components has demonstrated that mineral contents are seasonal and climate dependent, thus pointing to a natural origin for this polluting form and pollution by organic matter and nutrients originates from anthropogenic sources, mainly as municipal wastewater.

Ecological risk assessment of heavy metals in sediment and human health risk assessment of heavy metals in fishes in the middle and lower reaches of the Yangtze River basin
TL;DR: Investigation of the middle and lower reaches of the Yangtze River in China found that heavy metals may be mainly derived from metal processing, electroplating industries, industrial wastewater, and domestic sewage, and Hg may also originate from coal combustion.
