Index Evaluation

This paper took the SongSan wastewater irrigation district of Liaoning Province, Anshan city as object of study. Base on the survey on the sewage irrigation situation, heavy metal concentration in rice grain and drinking water were measured through single pollution index evaluation and comprehensive pollution index evaluation (Nemerow index method). It could be served as the basis for environmental management and relevant laws and regulations. Experimental results showed that drinking water were not polluted by heavy mental. Sewage irrigation had a comparatively small impact on drinking water. According to the heavy mental determination results of grain crop seeds, it can conclude that the Cu and Pb content were above the national food quality standard. The pollution is serious, however, the content of Zn and Cd were below or close to the national food quality standard, which is in danger of exceeding the standard. Determined by comprehensive pollution index, it showed that the rice in the whole sewage irrigation is serious polluted by heavy mental. The heavy metal pollution presented the characteristics of extensive area-source pollution. Pollution intensity was strengthened and more difficult to be managed.

Pollution Status

Abstract The present study focused on pollution status of groundwater in the industrial areas of Challawa and Sharada in Kano city based on pollution indices, statistical and spatial analyses. Twenty groundwater samples representing groundwater of the studied areas (Ten from each area) were analyzed for the presence of Cd, Cr, Ni, Fe, Mn and Zn using atomic absorption spectrophotometer. The result showed 95%, 5%, 60%, 15% and 25% of the analyzed water samples had detectable Cd, Cr, Ni, Fe, and Mn above the drinking water limits of both Nigerian standards for drinking water quality NSDWQ and World Health Organization (WHO) with Cd dominating other analyzed heavy metals in the groundwater. Evaluation of heavy metal pollution revealed a low polluted status based on the contaminant index (Cd), synthetic pollution index, heavy metals evaluation index, and heavy metal pollution index. Metal index categorized the groundwater as seriously polluted. The statistical evaluation gave strong and positive correlations between indices and a moderate one between the metallic ions. Component analysis revealed a strongly positive loading of Fe, Ni and Zn while Cd had a strong negative loading. Cr and Mn were positive and moderately loaded. Statistical analyses suggested both anthropogenic and geogenic sources for the heavy metals mainly from the industrial and agricultural practices and rock weathering processes, respectively. This study is expected to be a useful tool in the planning, monitoring and mitigation of pollution activities in the area. Article Highlights The pollution status of groundwater with respect to heavy metals was investigated in the Challawa and Sharada industrials zones in Kano city Nigeria The concentration of Cd, Fe, Ni, Cr Mn and Zn was determined using the AAS Different Pollution indices of HPI, HEI, SPI, Cd and MI were utilized to categorized the area as low, medium and highly polluted. Spatial and temporal distribution maps demarcated based on the metal concentrations and computed indices in the area. CA, PCA, and HCA were used to identified the geochemistry, relationship, sources and origin of heavy metals in groundwater. The study revealed zones with low to high-risk groundwater in terms of toxic heavy metals and pollution status.

Heavy Metal Assessment

This study goals to assess the concentrations of specified Heavy Metals (HMs) and quality of taps drinking water of Ramadi city, western Iraq. Heavy Metal Pollution Indices like heavy metal pollution index (HMPI ), heavy metal evaluation index (HMEI) and contamination degree (CD) were applied to assess the supplied water. The average concentrations of Lead (Pb), Nickel (Ni), Chromium (Cr), Arsenic (As) and Cadmium (Cd) in most stations exceed the maximum admissible concentration, while Iron (Fe) in most of stations was within the maximum admissible concentration according to local and global guidelines. (HMPI ) values of most stations were exceed the maximum critical value of 100. (HMEI) values of most stations were exceed the value of 10 recommended for drinking water. (CD) values of most stations were exceed the value of 1 recommended for drinking water. The pollution origins were assessed using principal component analysis (PCA) and clustering analysis (CA). The results indicate that contamination comes from anthropogenic causes being the most common and lithogenic sources being the least common. The present concentration of (HMs) in taps water is causing health and environmental problems, water with high (HMs) concentrations would need to be treated before being supplied to consumers.
