“…Solidified sea bottom sediments, when dredged, normally gives off horrible smell. A study was conducted with solidified sea bottom sediments for the construction of an artificial tidal flat in Ago Bay, Japan (Dabwan et al, 2017) [9]. In-situ solidification system for the treatment of sea bottom sediments, the ''Hi-Biah-System" was developed and the dredged sediments were thus first treated.…”

In the coastal areas, dredging operations are undertaken for creation, draft enhancement and maintenance of navigable channels for port and harbor activities. Dredging may also be performed in rivers or reservoirs for similar reasons. The dredged sediments may be disposed at on-land or oceanic sites. In the recent years, inexpensive ocean dumping is being eliminated as a disposal alternative, causing a crisis in the management of sediment. In construction industry, production of concrete creates heavy demand on the supply of raw materials for cement and also aggregates for concrete. In many locations, habitat restoration and tidal flat creation also generates demand of fine aggregates. It has been observed that at several sites, supply from quarry is not always an economic and feasible option. Sustainable solution to both the aforementioned problems is re-using the sediments from river and ocean in construction industry or bio-diesel production. Various applications attempted in construction industry include those for production of cement, as fine aggregate in concrete, in construction of pavements, in production of lightweight concrete, among others. This article presents a review of approaches employed to recycle dredged sediments in construction industry and biodiesel production.

“…Bivalves and different species of fishes have been used to study the accumulation of heavy metal on water ecosystems either in their tissues or in their bones [4][5]. Chemical reactivity of ions with cellular structural proteins, enzymes, and membrane system in mammalian systems is primarily due to metal ion toxicity with cellular structural proteins, enzymes, and membrane system.…”

The major goal of this study is to determine the bioaccumulation of heavy metals in the tissues and bones of Red Hybrid Tilapia (Oreochromis niloticus) and Mackerel (Rastrelliger kanagurta) taken from two distinct sites in Terengganu state, Malaysia, namely Kijal and Paka. Zinc (Zn), copper (Cu), nickel (Ni), and lead (Pb)were the metals examined. Soil analysis also was carried out for the same elements. The tissues and bones of the fishes were separated before further analysis was made. Drying process technique was used to determine the moisture content for all samples at 80 °C for 24 hours. Water content ranged between 70 & 77%. Triplicate samples were evaluated by using Atomic Absorption Spectrophotometer (AAS) to find out heavy metals concentration. Oven and Teflon beakers were used to fully digest all solid samples at 120 oC for 3 hours. Highest readings of Zn, Ni and Pb were found in the fish bone for the samples collected from both mentioned locations. However, different pattern was noticed for Cu where higher values were found in the tissues for the same samples. Values of Pb in the tissues were higher than the acceptable value in edible fish by Food and Agriculture Organization (FAO); 1 ppm and Malaysian Food Act (MFR) & World Health Organization (WHO); 2 ppm, whereas values of Cu, Zn were in the acceptable range set by the same organizations. No values recommended for Ni by MFR. In general heavy metals in the bones and tissues from both locations can be sorted in descending order as follows; Pb>Zn>Cu>Ni. Soil samples collected from both locations showed different pattern where high concentration was found for Zn followed by Pb then Cu and Ni. Moreover analysis for soil samples collected from Paka River showed higher content for all elements compared to Kijal. More investigation is needed to clarify whether this contamination is solely from industry or due to geology of the area.
