Present study was aimed to investigate the community structure and size distribution of Icthyoplankton sampled from Kuantan River, Malaysia. Sampling was conducted from May 2015 to August 2015 using modified bubu light trap in Kuantan river and its immediate tributary (Belat river). A total of 78 larvae representing 4 families and 6 genus were sampled and size distribution were measured using Dino capture 2.0v portable microscope. Significant influences of selected water quality parameters on the distribution of Icthyoplankton were observed (p < 0.05). Representatives of larvae belong to gobiidae, eleotridae ambassidae and leiognathidae were recorded during sampling and few larvae were unable to be distinguished morphologically and hence stored for further DNA barcoding. Modified bubu light trap method designed and adopted in this study can be successfully used to sample Icthyoplankton in rivers where the depth and turbidity are the key limiting factors during sampling.

Environmental pollution by heavy metals is a serious threat to human and ecosystem. Accumulation of heavy metals in the biota may pose hazardous impact on public health and other living organisms. By using gastropods Neritasp as bio-indicator, the levels of heavy metals in their soft tissues can determine the contamination of heavy metals in the Tanjung Lumpur Mangrove along the Kuantan River. The aim of this study is to identify copper, cadmium, chromium and iron accumulated in the tissue of Neritasp, to investigate the concentration of the copper, cadmium, chromium and iron in the molluscan tissue among the different sizes of gastropod Neritaspand to compare the concentrations of heavy metals in a gastropod Neritasp tissue among the different stations of Kuantan River, Pahang. Gastropods of Neritasp were randomly collected along the river. The tissues of gastropods were digested with nitric acid. Then, concentration of copper, cadmium, chromium and iron were analyzed by using flame atomic absorption spectrophotometer (AAS) model Perkin Elmer SIMAA 6100 graphite furnace. Neritasp accumulate copper the most in their tissues compared to other heavy metals. The concentrations are around 189.8 µg/ L – 247.95 µg/ L. The highest concentration of copper is in Station 3 which is at 241.67 µg/ L. The second highest concentration is iron or ferrum where the concentrations are around 121.25 µg/ L – 174.55 µg/ L. Station 3 was identified to have the highest concentration of iron at 161.12 µg/ L. Followed by, chromium which the concentrations are around 23.49 µg/ L – 46.15 µg/ L. The highest concentration of chromium is Station 1 at 34.82 µg/ L. The lowest concentration of heavy metals is cadmium which is around 8.69 µg/ L – 18.46 µg/ L. Also, Station 1 showed the highest concentration of cadmium at 17.56 µg/ L. This study can be used to identify contamination of heavy metals in marine zone by using bio-indicator to avoid environmental perturbation.

A study on physicochemical parameters and distribution of phytoplankton communities was carried out at Kuantan estuary, Pahang, Malaysia. The study was carried out in September, 2011 and November, 2011 to determine the spatial distribution of phytoplankton from three different stations during the pre-monsoon and monsoon seasons. The phytoplankton and water quality were analyzed using standard method outlines by APHA, 1998. The temperature recorded was between 27.29 oC to 29.33 oC, pH was from 6.96 to 8.24, conductivity range from 33.50mS/cm to 47.85mS/cm, dissolved oxygen ranged was from 4.25 mg/L to 5.84 mg/L, biochemical oxygen demand was from 3.37 mg/L to 1.60 mg/L, salinity range from 21.01 ppt to 30.72 ppt, total dissolved solids range from 21.80 g/L to 31.60 g/L and total suspended solids range from 0.024 to 0.044. The nitrite concentration was range from 0.078 mg/L to 0.088 mg/L during monsoon while in the pre-monsoon seasons the range was from 0.018 mg/L to 0.025 mg/L. Similarly, ammonium concentration was from 0.3056 mg/L to 0.0670 mg/L. The phosphorus content was range from 0.0110 mg/L to 0.0897 mg/L. The pre-monsoon season phytoplankton (1466 Cells/L) was found to be higher than the monsoon season phytoplankton (644 Cells/L).

Cesium 133Cs natural concentration is low and not toxic. It acts as short term pollutant in air but in soil it has long persistence. Plant uptake being the pathway of entrance of Cesium in biosphere. Two major radioisotopes of Cesium that proved to be pollutants are Cs 137 & Cs 134 they emit β and γ radiation. Those radiation enters terrestrial environment through nuclear testing and accidental or legalized discharge of nuclear waste from nuclear reactors. However it has been evaluated that concentration of uptake determines its hazard potential to plants. Details are presented in present chapter about its percolation, factors effecting its uptake and impacts on the plants. Radiocesium has a long term radiological impact on the environment as this radionuclide is readily transferred to human through food chain. Plant uptake is the major contributor in this shift. In the current chapter factors involve in translocation of radiocesium in environment has been reviewed. Plants significant in phyto remediation of radiocesium from environment has been assessed. Radiocesium phytoremediation was found too slow in restoration activity. In accidental situation fast growing Cs accumulating plants are required whereas at small or domestic scale traditional counter measures like crop varieties that do not uptake Cs should be used to block or restrict entry into food chain. however the limitation found in this is the slow uptake and accumulation of radioactive biomass at the end.

Sanitary landfill leachate is considered as highly polluted wastewater, if without any treatment and discharge into water system will affect water quality. This study was carried out to assess the treatability of the semi-aerobic landfill leachate via coagulation-flocculation using poly-aluminum chloride (PAC), cationic polymer and modified micro sand. Leachate was collected from Pulau Burung Sanitary Landfill located in Penang, Malaysia. Coagulation-flocculation was performed by using jar test equipment and the effect of pH, dose of coagulant and polymer toward removal of chemical oxygen demand (COD), color and suspended solid (SS) were examined. Micro sand also had been used in this study to compare settling time between coagulation-flocculation process with and without the aid of micro sand. The optimum pH, dose of coagulant (PAC) and dose of polymer (cationic) were achieved at 7.0, 1,000 mg/L and 8 mg/L, respectively. The dose of micro sand used for the settling time process is 300 mg/L. Results showed 52.66 % removal of COD, 97.16% removal of SS and 96.44% removal of color were obtained under optimum condition. The durations of settling time to settle down the sludge or particle that formed during coagulation-flocculation process were recorded at 1 minute (modified sand), 20 minutes (raw micro sand) and 45 minutes (without micro sand).

This study was conducted to enhance the ability of activated carbon to remove ammonia by modifying its surface as ion exchanger. The study involved the determination of the capabilities of modified activated carbon to remove ammonia from leachate using fixed bed column. Adsorption capability was determined based on the percentage of ammonia removal. Thomas and Yoon and Nelson models were used to determine the adsorption capacity for both modified and bare activated carbon. Results indicated that modified activated carbon has higher removal ability for ammonia with the maximum removal up to 94.30% compared to bare activated carbon with maximum removal of 64.05%. Based on Yoon and Nelson model, the maximum capacity value, qo was found to be 3.063 mg/g using modified activated carbon which is higher than bare activated carbon with the value of 1.478 mg/g. It can be concluded that the modified activated carbon has a higher ion-exchange capacity for removing ammonia removal compared to bare activated carbon.

Biodegradable and eco-friendly materials are preferred due to less environmental impacts in compare to synthetic and chemical compounds. Serishm is known as a natural protein based material which includes Collagen and has been considered as an ancient coating on textile materials. However, there is a lack of scientific approach and experimental finding to show the capability of using this material as the fire retardant for fabrics. Therefore, the main objective of this work is to investigate the possibility of using Serishm as a natural fire-retardant material. 23 various samples in fabric type (polyester, cotton and cotton/polyester) , Serishm content in 150 cc water (5, 10 and 15 g) were investigated under various conditions of padding pressure (2, 3 and 4 MPa), padding times (2, 3 and 4 times) andmethod of coating (pad dry cure, conventional method and injection molding of silicone-resin. Moreover, as cotton fabrics were highly flammable, various nano-silica contents (2, 4 and 8%) were used to determine the most appropriate condition for cotton fabrics. Flame retardancy and physical properties of each sample were evaluated. According to the test results, polyester fabric coated by Serishm showed better flame retardancy in compare to cotton and co tton/polyester fabrics. By increasing the padding times, the sample was capable to stop the firing procedure. The conventional coating showed better results in compare to padding methods, while the injection molding was the most appropriate method in compare to the other methods. It was concluded that the protein resin could completely penetrate into the fabric texture during injection molding. Therefore, by applying Serishm through injection method even cotton fabrics showed better flame retardancy.
