“…Literature survey reveals different multivariate GIS approaches for determining the heavy metal contamination in agricultural soil [8,[43][44][45][46][47][48][49][50] in many parts of the world, but only a few articles are focusing on the analysis of the metals concentrations in soils [38], sediments [51][52][53] and water [54][55][56][57], in the United Arab Emirates. Apart from the mentioned articles [38,[51][52][53][54][55][56][57], only one study [58] presents the soil characteristics in the Eastern Arabian Desert Region using as investigation tools the ICP-OES with GIS Mapping.…”

The aim of this study was twofold. Firstly, we performed a land capability class determination of the agricultural soils from the Abu Dhabi Emirate, the United Arab Emirates, based on the concentrations of 17 chemical elements determined in the soil samples collected from 84 locations. Secondly, we assess the soil pollution with different metals, using several pollution indices. The results of Principal Component Analysis (PCA) shows that four principal components (PCs) are responsible for describing the total metals concentrations’ variance, the highest contribution on PC1 being that of Mn, and Cr, on PC2 that of Fe, on PC3 that of Cu, and on PC4 that of Al. After determining the optimal number of clusters, we classified the sites into three clusters, while the studied metals were grouped function on their concentrations. Then, we used five indices to assess the pollution level of the soil at the study sites and in the clusters. The geo—accumulation index (Igeo) indicates uncontamination/moderately contamination with Cu in cluster 1, uncontaminated/moderately contaminate soils with Cd, Cu, and Ni in cluster 2, and uncontaminated/moderately contaminated soil with Cu and moderately contaminated with Pb, Zn, and Ni in cluster 3. By comparison, the enrichment factors overestimate the pollution of the studied sites. The pollution load index (PLI) indicates a baseline level of pollution at 14 sites and the deterioration of the soil quality at four sites. The Nemerow pollution index provides similar results as PLI.

“…CDI ingestion and HQ ingestion values were estimated using equations (1) and (3) . The RfD ingestion values used for each heavy metal are as follows: Cr = 3 μg/kg/day [ 39 ], Cu = 40 μg/kg/day [ 40 ], Fe = 700 μg/kg/day [ 41 ], Mn = 140 μg/kg/day [ 42 ] and Zn = 300 μg/kg/day [ 43 ].…”

Risk assessment via oral and dermal pathways from heavy metal polluted water of Kolleru lake - A Ramsar wetland in Andhra Pradesh, India

The Kolleru Lake, India is a famous wetland of international significance. Analyses of certain potentially toxic heavy metal ions in water indicate that this freshwater lake is characterized by highly heterogeneous distribution of chromium (Cr; 4.5–80 μg/L), copper, iron (Cu, Fe; below detection limit), manganese (Mn; 1–313 μg/L) and zinc (Zn; below detection limit). Non-carcinogenic health risk assessment indices like hazard quotients ( HQ ) and hazard indices ( HI ) are estimated following the guidelines recommended by the US Environmental Protection Agency (USEPA). These indices are found to be within the acceptable limit (<1), indicating negligible potential health risk via ingestion and dermal routes. However, when the average values of these indices pertaining to the Kolleru lake are normalized with similar estimates from clean and uncontaminated global surface water, both high and low ratios are obtained. While Cr (12.5), Cu (2.3) and Mn (3.7) exhibit high ratios, those of Fe (0.09) and Zn (0.99) show respectively low and comparable values. The significance of such heterogeneous distribution of hazard indices and their ratios are discussed. Further, average carcinogenic risk levels of the adults and children due to Cr ingestion are estimated to be 0.00154 and 0.0022, respectively. Both values are higher than the permissible levels recommended by the USEPA. As a remediation measure, it is recommended that monitoring the levels of heavy metal in water and other items like fish in the lake or rice and vegetables grown in the area is needed to be carried out at regular intervals. This study therefore offers requisite perception to the local government and health officials to evolve their plan of action so that effective management and mitigation of water quality of the Kolleru lake can be administered.

Groundwater is one of Earth's most precious natural resources [1]. It is vital to human health and the quality and quantity of grains because it affects soils, crops, and the surrounding environment [1,2]. However, due to environmental changes andhuman activities, groundwater quality is deteriorating at an alarming rate [3]. In recent years, the excessive use of chemical fertilizers and pesticides in agricultural areas hasbecome a major source of groundwater pollution, attracting considerable attention [4,5]. Since 2006, China has become the world's largest producer and consumer of fertilizers. In 2016, global fertilizer consumption was approximately 187 million tons, of which China's consumption was 59.84 million tons [6,7]. The large-scale use of chemical fertilizers,
