The study examined the effect of sub-lethal level of Linear Alkylbenzene Sulphonates (LAS) on some selected electrolyte and metabolic indices of juvenile Heterobranchus bidorsalis. The fish were exposed to varying concentrations of LAS (0.00 mg/L, 0.01 mg/L, 0.02 mg/L and 0.03 mg/L, respectively) in a semi-static tank for 14 days. The chemical test analysis of LAS showed that only total suspended solid (196.8 mg/L), total alkalinity (56.1 mg/L) and nitrate (7.9 mg/L) exceeded Federal Environmental Protection Agency (FEPA) and Standard Organization of Nigeria (SON) permissible limits. Conductivity and dissolved oxygen (DO) of the water parameter differ significantly (p < 0.05) from the control and among dose concentration. Electrolyte values (K+ and Ca2+) were not significantly (p > 0.05) different at all level of LAS concentration. However, there were significant (p < 0.05) differences in Na+ concentration. The highest value for Na+ (16.00 + 1.16 Mmol/L) was obtained at 0.02 mg/L, while the least (5.35 + 0.45 Mmol/L) was recorded in the control at 0.00 mg/L. There was significant (p < 0.05) differences in values of urea in the experimental group, except between 0.01mg/L (1.53 + 0.05 mg/dm) and 0.02 mg/L (1.60 + 0.06 mg/dm). On the contrary, there were significant (p < 0.05) differences in all the values of creatinine recorded in this study. The values increased down the experimental group in a dose dependent pattern. The highest value of creatinine (54.45 + 4.96 mg/dm) was recorded at 0.03 mg/L dose concentration while the least (30.47 + 7.65 mg/dm) was obtained in the control (0.00 mg/L). The present study concluded that LAS has impact on the metabolites and electrolytes especially creatinine and the Na+. Therefore, LAS could be very toxic at high concentrations and as such, indiscriminate discharge of LAS effluent into aquatic environment should be averted.

Phytoplankton plays an important role in primary productivity in marine environment. Various environmental changes in coastal area will impact the water quality and their phytoplankton compositions. The purpose of this study is to examine the abundance of phytoplankton from two different sites, i.e Tanah Merah (close to mining site) and Semujur Island (away from mining site) in Bangka Island. Phytoplankton and water sample were collected on June- August 2018. Water quality was measured using water quality checker, whereas the phytoplankton was identified under the microscope with a magnification of 100x. Non-parametric Kruskal test and T-test analysis was performed to determine the abundance, diversity, uniform, and dominance of phytoplankton between Sites, respectively. Statistical analyses showed the abundance of phytoplankton at Semujur Island was significantly higher than that at Tanah Merah (p = 0.003). In additions the diversity, uniform, and dominance were also significantly different between sites (all p <0.05). In Semujur Island, Diatoms (Thalassiothrix, Chaetoceros and Thalassionema) were more dominants than the Dinophyceae group. However, in Tanah Merah, the genera Ceratium belong to class Dinophyceae was more dominant than the class Bacillariophyceae. These results performed that the phytoplankton in Tanah Merah and Semujur Island was affected by environment, in this case the mining area. The water quality in Semujur Island (non-mining Area) might have good quality than in Tanah Merah (mining area). The average value of turbidity and Total Suspended Solid in Tanah Merah Waters causes low abundance of phytoplankton. It can be concluded that tin mining can disrupt the abundance and composition of phytoplankton as a primary producer of waters.

Comparison Of Analytical Methods

Abstract Al, Cd, Cu, Fe, Pb, Mn, and Zn were determined in water samples collected from Clear Creek and North Clear Creek, CO, that had been impacted by acid mine drainage. These samples contained a wide range of total suspended solid concentrations. The samples were prepared and digested by dissolved, acid-soluble, total recoverable, U.S. Environmental Protection Agency (EPA total), and Contract Laboratory Program (CLP) total procedures. The CLP method resulted in the highest reported metal concentrations for 67% of the analyses (primarily Al, Cd, Cu, and Fe), the EPA total method for 11 % of the analyses (mainly Mn and Zn), and the acid-soluble method for 9% of the analyses. For the remainder (13%), 2 or more methods resulted in similar metal concentrations. The same analyses using the Three Kids Mine standard reference material demonstrated that the EPA total and total recoverable methods underestimate the maximum metal concentrations in sediment-bearing water samples. In addition, use of acid-soluble or total methods is inappropriate to determine compliance with aquatic water quality standards that were originally promulgated on the basis of dissolved concentrations

Feasible Alternative

In this study, integrated pretreatments and aerobic digestion processes were investigated in order to provide a feasible alternative that can achieve effective sludge reduction. An ozone treatment in the presence of ionic manganese, a catalyst, increased the sludge reduction ratio three times higher than that of a single ozonation, presumably due to an increase in OH radical production. The ozone treatment yielded the effective sludge reduction ratio with an increasing ozone dosage, and an effective dosage of the catalyst was found to be 4 mg-Mn/g-TS. When a mechanical pretreatment and an ozone/catalyst were applied in a series, the integrated process, even at a half mechanical intensity and a half level of ozone dosage, showed higher and faster sludge reduction than each single process did. In addition, the integrated pretreatment process showed the highest dewaterability of the treated sludges. A ratio of sludge cake generation, which was newly introduced to quantify overall performance of sludge treatment processes, showed that the integrated pretreatment followed by the aerobic digestion yielded approximately a half of the sludge cake volume compared to the single aerobic digestion. Therefore, the integrated pretreatment can be a feasible method for the effective reduction of total suspended solid and the final volume.

Water used for washing carcasses of slaughtered animals and slaughter house is referred to as abattoir wastewater. This study was designed to investigate the microorganisms associated with abattoir wastewater and to establish the biodegradation potential of abattoir wastewater microbiota. Isolation of the microbes was carried out using pour plate technique. The total viable count for the microbes’ ranges from 2.5×104 - 4.6×105 cfu/mL. Results revealed that all the physicochemical parameters exceeded the permissible limits (total dissolved solid (TDS) 1748mg/L, total suspended solid (TSS) 176mg/L, biochemical oxygen demand (BOD5) 91 mg/L and chemical oxygen demand (COD) 227 mg/L). Microorganisms isolated include Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Bacillus anthracis, Aspergillus niger, A. flavus, Mucor sp, Trichophyton quickeanum and Penicillium sp. Some of the microbes were observed to have biodegradation potential by their ability to grow on mineral salt media (MSM) incorporated with starch, cellulose, crude oil, kerosene and diesel as the sole source of carbon and energy. This study suggests that abattoir wastewater harbors microorganisms that could be hazardous to public health when discharged into the environment untreated hence the need for strict monitoring. These microbes isolated could be employed as agent of bioremediation of wastewaters. Key words: Abattoir; Biodegredation; Isolation; Microbiota; Wastewater

Wastewater resulted from the batik dying process is known for its environmentally hazardous substances including hazardous natural and synthetic organic matter, suspended particles, and hazardous metal. But in the micro and medium scale batik textile business, wastewater treatment is mostly not carried because it does not give benefit for the owner. Economical wastewater treatment constructions can be an alternative for the business owner for their free operational cost. Batik wastewater treatment ought to be carried out to meet government standards but most importantly to decrease hazardous pollutant’s concentrations so it does not harm the environment. This society service project aims to provide alternatively economical wastewater treatment for batik business owners by applying simples and cheapest yet effective treatment methods to reduce pollutant concentrations in wastewater. Methods applied in this project including sedimentation, filtration, and landfill-bioremediation. The laboratorium analysis result shows that sedimentation and filtration are significantly reduced total suspended solid particles in wastewater from 2450 to 100 mg/L in line with wastewater decoloring from dark blue to clear yellow.

Researchers recently have suggested that behaviorally disordered students exhibit deficits in test-taking skills, the ability to use test cues to maximize test scores. These deficits may account partially for the low achievement scores commonly associated with this population. The present investigation was intended to determine whether behaviorally disordered students could be trained to improve test-taking skills relevant to content area tests. First, 34 behaviorally disordered adolescents were administered Slakter, Koehler, and Hampton's (1969) test of test-taking skills, matched for grade and pretest score, and assigned at random to experimental and control groups. Experimental group students were provided with training in specific test-taking skills relevant to content area, teacher-made tests, over a 5-day period while control students received their regularly scheduled instruction. After the training period, a posttest was administered. A two-way (group by test) analysis of variance indicated that experimental condition students scored significantly and substantially (nearly 50%) higher than untrained control students. Implications for research and training are discussed.

The Relationship

Total suspended solid (TSS) is one of the parameters that determines whether or not a body of water is polluted. One factor that influences the amount of TSS content is the characteristic of rainfall in an area. Purpose of this study was to determine the relationship between the effect of rainfall characteristics and TSS content in Ciliwung River. Multiple regression analysis was used for analytical method.  Results of multiple regression analysis showed that the correlation coefficient (adjusted R2) for the factors of rainfall, discharge and sediment show a low correlation to changes the content of TSS in Ciliwung River. The value of each correlation coefficient in the upstream, middle, and downstream of Ciliwung River are 0.21, 0.31, and 0.09 respectively. According to the F test, rainfall, discharge and sediment  were significantly affect TSS content in the upstream and middle stream.  Based on t test, it is known that only rainfall affect TSS content in the upstream and midlle stream.
