“…Heavy metal levels in most seafood from Lingdingyang were higher than the safety limit (ShuaiLong Wang, 2013). A study done by Mishra et al (2007) in the TransThane Creek area of Mumbai, measured the trace element in different types of marine organisms and reported the HQ values of 0.01 (50th percentile) and 0.005 (95th percentile) in case of the ingestion of Cd. The same study also revealed lower HQ values for Cr, Ni, Zn and Cu and suggested that consumption of fish samples were within the safe limit (Mishra et al, 2007).…”

Similar to the findings, Tu et al (2008) worked on the concentration of Cr, Cu, Zn and Cd, and measured HQ values of less than 1 which indicated that the local residents were not exposed to potential risk via consumption of shrimp.…”

The study and application of health risk assessment techniques are crucial in order to understand the risk of exposure to heavy metals and other harmful pollutants. It entails evaluating the risks of exposure at various concentrations and with reference to certain standard values approved by World Health Organization (WHO) and United States Environmental Protection Agency (USEPA). Investigation of water contamination with heavy metals has become the prime focus of environmental scientists in recent years. Effluent discharges into aquatic system affect living organisms within the receiving environment. The concentrations of these metals were mostly assessed at 50th, 75th and 95th percentile and various exposure evaluated. This review covers studies in water, air, soil and fish samples. Air risks assessment was not given the needed attention and children were more susceptible to the hazard than adult, especially lead toxicity, resulting in health complications. Heavy metals bio accumulates over time, and lethal upon exposure at low concentrations. This review will assist risk managers to minimize the exposure at optimum level as well as for the government to formulate policies in safe guarding the health of population.

“…Thereby, in practical assessment work, it is usually found that the factors with high concentration (heavily polluted) have a fateful influence on the final assessment results obtained by the single-factor method. However, the dominant parameter and the average contribution of all factors were both taken into account for the comprehensive index method used in the present research, and a better environmental quality was achieved as the assessment result [9] . The difference mentioned above between the two pollution index methods can be further proved by the application example of the models given in Table 5.…”

Four assessment methods (two pollution index and two fuzzy mathematical models) were employed to investigate the environmental quality of eight soils around a heavy metal contaminated site. From the results of analysis, comprehensive index model is more reasonable compared with the single-factor index method; Compared with the pollution index, in fuzzy mathematical methods, membership functions were used to describe the limits between different pollution degrees, and different weights were allocated for the factors according to pollution contribution. In the single-factor deciding model, the dominant factor was given more attention, and the effects of the other factors were weakened. However, in the weighted average model, the contribution of each factor was well taken into account, and the weights were allocated for the factors according to the contribution degree. In fuzzy mathematical methods, membership functions were used to describe the limits between different pollution degrees, and different weights were allocated for the factors according to pollution contribution. Introduction of membership degree and weight of each factor to fuzzy mathematical models made the methods more reasonable in the field of environmental quality assessment.

“…There are three possible routes by which metal can be derived, namely, (1) from solution, (2) from ingestion of food, and (3) from the ingestion of particulate matter containing metals [27]. Moreover, direct uptake from the sediment particles can be an important additional source of sediment-bound contaminations for sediment-feeding organisms [28].…”

Abstract" systematic study on the natural radionuclide Poand heavy metals in marine organisms has been undertaken to establish a baseline data on the contamination of a coal burning power plant area. The organism samples have been collected from the local fish market which was very near to Sultan salauddin abdul aziz power plant and analysed for Poand heavy metals using alpha spectrometer and ICP-MS, respectively. The content of Poand heavy metals in analyzed organisms varies according to the feeding habits and ecological niche.
