The purposes of this study are to investigate the types of different collectors and their most effective height of installation in the green mussels cultivation (Perna viridis L.) impacted by heavy metal pollution in mangrove and non-mangrove waters;  and to determine the content of heavy metals, especially Pb, Cu, Cd, and Hg in green mussels cultivation. This research was conducted from April to September 2018 in the coastal area of Karangdempel, Losari Sub District, Brebes Regency. The method used in this research was experimental. The results showed that the growth of green mussels after 6 months period of maintenance reached 7-9 cm long, weighing 10-13 grams per head and yielded 23-30 heads per collector. The most effective mussel collector was net sacks installed at a height of 30 cm from the bottom of the water. The number of mussels per collector was more in mangrove location compared to those in the non-mangrove location, while their growth in length and weight were relatively the same. Heavy metal content in seawater and in the mussel meat are still within the permissible limits of the Indonesian National Standard, except for the Cu content in the mussel exceeding the allowable limit; but it was relatively still safe accoring to the Decree of the Director General of Drug Control and Food, Indonesian Ministry of Health, No. 03725/B/SK/1989. Pb content in sediments in both location of green mussels cultivation and the Cisanggarung River basin is still within the safe limits. The content of Cd, Cu, and Hg in sediments tends to be high. Heavy metal content both in mangrove and non-mangrove areas was not different as a result of mangrove reforestation dominated by seedlings and saplings with little influence on the quality of the water ecologically and economically.

The use of sludge as fertilizers helps to the recycling of nutrients to the environment due to its beginning from wastewater and therefore relatively high content of nutrients and organic matter. However, wastewater does also contain hazardous compounds like heavy metals and micro pollutants which eventually are separated to the sludge during the treatment processes at the wastewater treatment plant. In order to improve the sludge quality, source tracking is a relatively cheap and effective way to find and eliminate hazardous compounds and prevent them from ending up in the sludge. The aim with this thesis was to investigate the fertilizer potential in sludge from wastewater treatment plant. The sludge is analyzed in terms of nutrient and heavy metal contents as well as physiochemical parameters. In order to determine the potential as fertilizer, the quality of the sludge is compared with other fertilizer alternatives, other sludge types and regulations for sludge use in agriculture. The work with sludge quality improvements in Gaborone is also investigated. Sludge from different stages along the treatment processes were collected in order to see differences in quality related to the treatment. The results shows that the samples of primary an aerobically treated sludge tend to have higher heavy metal content than the secondary sludge. The quality of the dry sludge samples indicates lower nutrient content than both the primary and secondary sludge, but similar heavy metal content. The analysis of dry sludge from indicates a low nutrient value and high heavy metal content in comparison to other selected fertilizer options and sludge from other. The processes for removal of nutrients from the wastewater are an important factor for the nutrient content in the sludge. Keywords wastewater; fertilizers; nutrients; sludge treatment

Water samples of six sampling sites (two downstream, two abattoir sites and two upstream sites) were analyzed using standard methods to determined and assessed heavy metal content of abattoir effluent on surface water quality of River Katsina-Ala, Benue State, Nigeria for rainy and dry seasons. Rainy season heavy metals results were; Cr6+ (0.032+0.06mg/l); Mn2+ (0.16+0.034mg/l); Cu2+ (0.86 +0.46mg/l); Pb2+(0.006+0.002mg/;Cd2+(0.0023+0.004mg/l) and the dry season results were: Cr6+(0.028+0.007mg/l); Mn2+(0.07+0.05mg/l); Cu2+(0.85+0.16mg/l); Pb2+(0.0030+0.014mg/l); Cd2+(0.0021+0.012mg/). Most heavy metals for both seasons were within the maximum permissible limit set by Federal Ministry of Environment, Nigeria (1991). The mean concentrations of Zn2+(1.70+0.29 mg/l) for rainy season and Zn2+(1.33+0.23mg/l) dry season were above the control and standard safe limits of < 1mg/l FMEnv (1991) for surface water quality. There was no significance difference (p<0.05) between the means from upstream and downstream sites for both seasons; though significance difference (p<0.05) existed at the abattoir sites. River Katsina –ala is slightly polluted. Heavy metal content from effluents from abattoir contributed to upset the physicochemical balance of the river. Bioaccumulation and bio-magnification of heavy metals may occur from prolong usage of the river water for drinking. It is suggested that the abattoir effluent be treated before discharge into the river to reduce environmental and health hazards.

Marine pollution occurs due to the entry of industrial waste containing chemicals into the aquatic will cause changes to its ecological conditions. Pollutants contained in the waste are in the form of sediment nutrients, pesticides, pathogenic organisms, waste and heavy metals. The purpose of this study was to determine the content of heavy metal Pb in green mussels (Perna viridis), water, and sediments in the Ngemboh, Gresik area and in the waters of the Nusantara Brondong Fishery Port, Lamongan, East Java. The research is observational research with analysis data using linear regression, simple correlation (pearson) and ANOVA. The data collection was carried out by purposive random sampling. The heavy metal content of lead (Pb) in green mussels in Ngemboh waters, Gresik has a heavy metal content of lead (Pb) of 0.871 ppm, 0.199 ppm, 0.161 ppm. The cause of the high content of heavy metal lead (Pb) at station 1 is because it is close to the mouth of the Ngemboh river, where both organic and inorganic waste originate from local residents. Meanwhile, the content of the heavy metal lead (Pb) in green mussels in the waters of the Indonesian fishing port in the archipelago of Brondong, Lamongan, has various values. The values of heavy metal lead (Pb) at both stations were 0.37 ppm and 0.053 ppm. The content of heavy metal lead (Pb) in green mussels has not exceeded the threshold specified in SNI 01-7387-2009, which means that green mussels are still fit for consumption.

Aims: To investigate the level of heavy metal contamination in the lettuce cultivated in Place: Savadkooh County in Mazandaran, Iran. Methodology: five samples were taken from the lettuce produced in this area and also from the soils in which they were cultivated, and the concentrations of Nickel, Lead, and Cadmium were measured by atomic absorption spectrometry. Descriptive and inferential statistics were used to analyze the measured data. Data analysis was performed by SPSS ver.16 at the 0.05 significance level. Results: The highest lead concentration, 0.07ppm, was observed in the sample No. 5 (Lettuce 5), the highest cadmium concentration, 0.008ppm, was measured in the sample No. 2 (Lettuce 2), and the highest nickel concentration, 0.07ppm, was observed in the samples No. 1 and 4 (Lettuce 1 and Lettuce 4). Conclusion: The results of this study show that while all the lettuces cultivated in the Savadkooh region contain some amounts of nickel, cadmium, and lead, these amounts are much lower than the limits specified in Iran’s national standard, and therefore these products are perfectly safe to consume. Also, the concentration of each heavy metal in the lettuces was found to be directly correlated with the corresponding concentration in the soil in which they were grown, indicating that the heavy metal content of the products increases with the increasing heavy metal content of the soil.
