Present study assesses the uptake and allotment of heavy metals in irrigated water, soil and tomato (Lycopersicones culentum) at the export processing zone of Bangladesh. The elemental distributions of the heavy metals in the plant organs and fruits were determined after the harvesting stage. The uptake and distribution of the three heavy metals Cd, Cr and Pb were found in the several organs of tomato in reducing pattern of green tomato>plant shoot> leaf> ripen tomato> plant root; leaf> ripen tomato> plant shoot> plant root> green tomato and plant shoot> leaf> ripen tomato> plant root> green tomato while Ni has more toxic metal in Plant root but less in ripe tomato. This outline of distribution in the plant organ showed the typical pattern of a prohibited plant with a higher concentration of metals accumulated in the plant parts than in the fruits. The reducing pattern of the bio-concentration factor (BCF) showed that the ability of tomato fruits to accumulate heavy metals was reduced as the level of contamination in plant parts.

This research aimed to study the guidelines for green building operations in Thailand’s construction industry and develop a structural equation model (SEM). According to global trends in sustainable development goals, issues about energy resources, pollution, and human surroundings are concerning. Each country’s green building criteria or discipline topics will be developed and improved for their condition. The research analysis emphasised the green building industry using descriptive, reference, and multiple statistics. The research results show guidelines for green building operation in 4 aspects. Each component aspect’s names are (1) Environment Arrangement, (2) Collaborative Creation, (3) Knowledge Management and (4) Technology Development. The hypothesis test showed that the difference in enterprise sizes revealed overall aspects that were not significantly different at 0.05. The analysis of the developed structural equation model showed that it was in accordance and harmony with the empirical data and passed the evaluation criteria. Its Chi-square probability level, relative Chi-square, the goodness of fit index, and root mean square error of approximation was 0.184, 1.084, 0.959, and 0.013, respectively.

Domestic sewage-based constructed wetland (CW) showed that the effluent from CW-system contain enough plant nutrients and enhanced the growth of microalgae. Hence, a pilot CW system employing Typha latifolia in domestic sewage, integrated with the cultivation wild type Chlorella sp. was investigated. Phytoremediation at 48 hours of detention time caused significant changes in its physicochemical properties and the generated effluent was notably attractive for the cultivation of microalgae. The microalga was grown in 6 treatments: treated-mixotrophic (T1), treated-heterotrophic (T2), treated-autotrophic (T3), control-mixotrophic (T4), control-heterotrophic (T5) and control-autotrophic (T6) conditions for 8 days inside an incubator. The results suggested that phytoremediation effluents integrated with mixotrophic cultivation of microalgae, utilising both light and carbon sources could be the most efficient, environmentally safe, sustainable and novel technique for synergistic resource generation and bioremediation.

This project deals with the environmental assessment of the Bagmati River in Kathmandu Valley, Nepal. Rapid population growth and urban development in recent decades have turned this river into a highly polluted water body. To delineate the contaminant hotspots, water and sediment samples were collected from eleven (11) sites along the river. Water samples were analysed for temperature, pH, total dissolved solids (TDS), conductivity, dissolved oxygen (DO), total suspended solids (TSS), turbidity, E. coli, biochemical oxygen demand (BOD), nitrate, total phosphorus (TP), chloride, and heavy metals in sediments. The data showed considerable degradation of the aquatic system. The TDS increased from 52 mg/L in Sundarijal (near source) to 595 mg/L near Teku (city center). Simultaneously, TSS increased from 43 mg/L to 1233 mg/L, with a contamination hotspot near the Thapathali area. DO quickly dropped below 2 mg/L at all sites near downtown. E. coli increased from 4000 MPN/100 mL in Sundarijal to 46,000 MPN/100 mL in Teku. The high levels of E. coli and the low DO were attributed to the direct disposal of sewage, house-hold trash, industrial effluents, and wastes from hospitals and slaughter houses. In recent years, sediment accumulation of heavy metals has also gone up, namely Cr (35%), Cu (59%), Fe (7%), Pb (7%), and Zn (25%). Phosphorus ranges from 0.2 mg/L at the source to 6.2 mg/L near the city. Phosphorus comes from the area’s wastewater treatment plant, industrial discharges, and sewage. From people’s survey results, 23% said they dispose off part or all of their trash into the river or directly on the street. The urban impact is also evident in the dramatic rise of dissolved Cl in water from the suburbs (26.2 mg/L) to the central city area (73 mg/L). Based on the results, areas near Teku, Thapathali, and Kalimati should be prioritised for immediate remedial measures. Urgent recommendations include dredging of stream sediments, contaminant source cutoff, stringent industrial regulations, and buffer strips and filter beds along the stream banks.

Groundwater in aquifers is one of the most significant renewable natural resources. It provides drinking water to more than 90% of the rural population. The majority of domestic and industrial garbage is disposed off in open dumping yards. As a result, groundwater becomes contaminated and of poor quality. Many therapy strategies are being used in various regions of the world to address this issue. We investigated the groundwater properties in a section of an industrial city in southern India and treated the contaminated groundwater using natural bio-coagulants in this study. Artocarpus heterophyllus (Jackfruit peel), Momordica charantia (Bitter gourd seed), Musa paradisiaca (Banana blossom leaf), and Cynodon dactylon were employed as eco-friendly bio-coagulants (Scutch grass). These coagulants are good at removing turbidity while also keeping the pH of the water stable. Furthermore, these natural coagulants lower BOD, COD, and salt levels. Groundwater can be utilised for home purposes after treatment. Because it is a low-cost and environmentally friendly approach, a vast population can afford it.

This study analysed factors influencing the decision to use chemical fertilisers by farmers at the household level, and it included a related assessment of nutrients in nearby water bodies. One focus group discussion was held at each site, and then a total of 198 and 58 households in Lake Phewa and Kulekhani Reservoir, respectively, were surveyed. The results reveal that 90% and 55% of households applied chemical fertilisers in Lake Phewa and Kulekhani Reservoir, respectively. A logistic regression model indicated that the two factors having a significant positive influence on the decision to use chemical fertilisers were higher vegetable yield and the amount of urea available to farmers Water sampling indicated that phosphorous concentrations were relatively high in both these water bodies compared to previous studies in other nearby lakes.

Every day, it becomes more difficult to find water. The main factor causing water body contamination is human activity. Groundwater becomes contaminated when improperly treated waste water from industries and other sources gets mixed with it. The primary objective of this initiative is to treat water that has been contaminated by toxic substances. The study’s focus is on the process of eliminating additional compounds such as sulphate, nitrate, phenol, fluoride, mineral oil, calcium, and turbidity. The usefulness of ground water for specific uses depends on its chemistry, physical characteristics, and bacterial makeup. The groundwater’s pH, fluoride, nitrate, sulphate, turbidity, hardness, phenol, and other characteristics were all measured. The treatments took into account aeration and sedimentation. The water is then recommended as safe for household and agricultural purposes.

Air pollution is characterised as the presence of one or more pollutants in the outdoor environment, such as dust, gases, mist, odour, smoke, or vapour. They are harmful to human, plant, or animal life or property or interfere with the healthy nature of life or property in specific amounts, characteristics, or periods. This study aimed to investigate the characteristics of ambient air pollution through relations between determinants to each SO2, NO2, PM10, and suspended particulate matter (SPM) by applying linear regression. The data has been obtained from the official websites of the Indian government based on the real-time pollutant concentrations monitored by stations in an urban and resident areas from 2000 until 2015. The data consisted of eight (8) variables; SO2, NO2, PM10, and SPM as outcomes, month, year, area, and monitoring stations as determinants. The model showed that the month, year, monitoring station, and area were correlated to SO2, NO2, and PM10 concentration. Yet, in SPM concentration, month, year, the station was correlated. The area was not correlated to SPM. Investigation of other predictors was needed to gain information about the increasing air pollution on a global scale.

The primary goal of this research is to evaluate the treatment of dairy effluent from a Coimbatore industry sector utilising algae bioreactor techniques. The activated sludge process is a biological wastewater treatment process for treating industrial wastewater for reducing solid particles and simultaneously treating dairy wastewater under aerobic conditions. In this present study, an aeration tank is designed and fabricated for the treatment of wastewater and sludge production by inoculating green algae. The algae bioreactor is operated continuously for 30 days by supplying oxygen. The wastewater characteristics are tested for their concentration to find the removal efficiency of the aerobic tank. This study attempts to reduce the pollutant concentration and CO2 emission from wastewater as well as produce fertilisers from this treatment. This method of treatment is sustainable and eco-friendly.
