The accumulation of plastic litter in the marine environment is a growing ecological concern. Microorganisms can create a biofilm on the surface of plastic litters making them more hazardous. Although plastics are difficult to biodegrade, they can act as substrate for microorganism attachment. To investigate this problem, biofilm coated plastic litters such as covers, films and ropes were collected randomly from Muthunagar and Inigonagar in Tuticorin coastal areas and analysed using FTIR-ATR. The spectra obtained demonstrate the presence of Polyethylene (PE), Polypropylene (PP), Polystyrene (PS) and Polyamide (PA). The concentration of biofilm formed on the surface of plastics is higher in Inigonagar compared to Muthunagar coastal area. Investigations were also conducted into the bacterial development on the plastic surface and in the surrounding water and sediment. Several bacterial communities including human pathogens namely Faecal coliform, E. coli, Salmonella sp., Streptococcus sp., Staphylococcus sp., Pseudomonas sp., Bacillus sp., Klebsiella sp., and Vibrio sp. were found to be associated with the collected plastic litters. We confirmed the weathering of plastic litters by carbonyl and vinyl peaks formation. According to the Carbonyl Index values plastic litters collected from Inigonagar exhibit higher degree of degradation compared to Muthunagar coastal areas. The present study could provide significant baseline information for both plastic pollution and biofilm composition in Muthunagar and Inigonagar coastal areas.

The volume of municipal solid waste in developing countries continues to grow, yet disposal and management have become significant challenges. As a result, a proper disposal strategy is required. The feasibility of making paver blocks from plastic waste for construction work was investigated in this study. Paver blocks manufactured from plastic waste (PP and HDPE) and sand in varied proportions were evaluated for compressive strength, water absorption, and abrasion resistance. Paver blocks were manufactured with plastic (PP and HDPE) to sand ratios of 30:70%, 40:60%, 50:50%, 60:40%, and 70:30%, or PP30, PP40, PP50, PP60, and PP70, and HDPE30, HDPE40, HDPE50, HDPE60, and HDPE70. The paver blocks were inspected after 28 days. Compressive strength, LA abrasion, and water absorption of paver blocks increased from 30% to 40% HDPE, then fell to 70%. As paver block PP content grew from 30% to 70%, abrasion and water absorption decreased. The compressive strength of PP paver blocks declined from 30% to 50% PP, then increased somewhat, and then fell to 60% and 70% PP. PP60 and HDPE40 paver blocks had the highest compressive strength, abrasion value, and water absorption. HDPE40 pavers have lesser water absorption and more abrasion than PP60 pavers. PP60 water absorption and abrasion were 0.53% and 11%; HDPE40 was 0.03% and 24.2%. PP60 and HDPE50 have compressive strength, abrasion resistance, and water absorption of 20.09 MPa, 11%, and 0.53%, respectively, and 13.06 MPa, 12.1%, and 0.03%.

Microplastics (MPs) are present practically everywhere in the coastal ecosystems, including the sediment of beaches and wetlands as well as the columns of surface and subsurface waters. Marine MPs are most frequently found in the near shore zones. Due to their potential negative impact on ecosystem functions, MPs have become a significant environmental problem worldwide. Contamination by microplastics has been well-documented around the world and it has drawn the attention of the scientific community, governmental and international organisations and the general public. In the present study, involving the isolation, assessment and characterisation of MP debris collected from six coastlines with recreation and fishing activities in Tuticorin district, the most common MP polymers identified are polypropylene, polyethylene, polyamide and polystyrene. The maximum number of MPs are found in the sediment samples of Tiruchendur (with an average of 8.33 5.3), and the least number of MPs are observed in the water samples of Aalanthalai (2 1.0). To assess the quality of water and sediment, we calculated the polymer hazard index (PHI), pollutant load index (PLI) and potential ecological risk index (PERI). Because of the presence of high-hazard polymers like polyamide (PA) and polystyrene (PS), the study areas have high PHI values (>1000). According to PLI values, water and sediment samples from Tiruchendur and Manapad are highly contaminated with MPs (PLI: 6.98 to 13.85), whereas samples from Aalanthalai, Kayalpattinam and Roche Park are less contaminated (PLI: 1.87 to 3.43). The PERI values of sediment samples from Tiruchendur show the highest ecological risk (PERI: 416.783). On the basis of anthropogenic activities, centres with recreational activities have substantially greater MP concentrations than the fishing locations, and the sediment samples are considerably more polluted with MPs than the water samples taken from the same locations, according to PLI values.

Surface water represents one of the most utilized sources for water distribution systems globally, despite the fact that rapid urbanization and industrialization has reduced its cleanliness. As a result, the end-user's health is seriously impacted by the dirty water. Nevertheless, it is clear that many developing nations, including India, pay little regard to or care about this crucial issue. The Vidhyadhari River has become a receiver of high organic and bacteriological load of entire Kolkata City through Basanti canal. As a result, the purpose of this investigation is to evaluate how rapid urbanization and industrialization has changed the water quality of Vidhyadhari River using Canadian Water Quality Index (WQI). We have used seasonal water quality data collected at two monitoring stations (Haroa bridge and Malancha) from 2011 to 2020 to study the water quality of Vidhyadhari River. Results of the study indicated that the annual WQI value of Haroa brigde ranged between 21.62 (very bad) and 62.89 (medium) with an average of 27.29 (bad), whereas annual WQI value of Malancha station ranged between 15.44 (very bad) and 43.09 (bad) with an average of 18.77 (very bad). In comparison to downward location, the water quality of Vidhyadhari River was somehow good at upstream i.e., Haroa brigde. According to WQI, the water quality of Vidhyadhari River fall into bad to very bad category, which indicated deterioration of river water quality. Factor analysis revealed that both stations are predominated by hardness cluster (hardness, calcium, magnesium and chloride) followed by cluster of total dissolved solids (TDS), sulphate and ammonia. Sewer, excessive human activity, industrial discharges, poor sanitation, and urban runoff outflow can be extrapolated as the main causes for the deterioration of Vidhyadhari River water quality. This study emphasized the significance of implementing measurement actions, introduction of watershed characteristics and implications for developing water management strategies.

Water crises is a major problem of Darjeeling, West Bengal, India where rainfall is plentiful. Darjeeling gets only one-third of its daily water requirement through municipal pipelines. The water supply network is mostly town centred so the peripheral areas are deprived of water. Private suppliers also supply water at Rs. 300/- per month per household. Darjeeling Municipality established in 1850 has a centralised water management infrastructure laid down between1910–30. The water supply system originates in Senchel Wildlife Sanctuary, located 15 kilometres upstream of Darjeeling with two lakes and a storage of 33 million gallons of water that is recharged by 26 springs. This centralised system fails to acknowledge the vibrant 90 odd natural springs in the town that people are dependent upon. These urban springs have diverse community-based management systems that have evolved over time and are now facing challenges of rapid urbanisation, market forces, upstream concretisation and contamination and reducing discharges. Due to deforestation which is leading to high runoff resulting to less recharge of groundwater. Women, are worst hit, as they have to travel miles to fetch water in this rugged terrainfor her family while their male counterpart are busy to make both ends meet. Every household maintains a kitchen garden whose water is also being procured by females through irrigation. Rooftop rainwater harvesting is the imperative way to mitigate the water crisis. Moreover, reuse, recycle and reducing wastage will help to mitigate this water crisis.

In the 21st century, groundwater has a pivotal role in ensuring water, food, and environmental securities worldwide. Systematic observation, protection and restoration are essential for sustainable management of water resources. Regular monitoring is key to investigate temporal changes in groundwater quality, and statistical trend tests define whether these changes are significant or not. This study focuses on investigating trend in seasonal groundwater quality in an alluvial coastal basin of West Bengal, India. The seasonal groundwater-quality data (pH, TH, TDS, Fe2+ and HCO3ˉ) of pre-monsoon and post-monsoon seasons were collected for 2011–2018 period and analyzed using three non-parametric statistical trend detection tests, namely: (i) Original Mann-Kendall (M-K) test, (ii) Modified Mann-Kendall (mM-K) test, and (iii) Spearman Rank Order Correlation (SROC) test. The trend magnitudes were estimated by using the Sen’s slope estimation test. Statistical analyses revealed that seasonal concentrations of all five groundwater-quality parameters have large spatial (block-wise) variation within the study area. The results of trend analyses indicated that seasonal TH and TDS concentrations mainly have significant decreasing trends (α = 5% or 1%), whereas seasonal HCO3ˉ and Fe2+ concentrations mostly show significant increasing trends (α = 5% or 1%) in different blocks. However, seasonal pH concentrations exhibited no trend. The mM-K test was found to be over-sensitive in finding trends than M-K and SROC tests. The SROC test was found to be less sensitive in detecting trends than M-K and mM-K tests. Trend magnitudes of seasonal pH, TH, TDS, HCO3ˉ and Fe2+ concentrations varied from –0.03/year to 0.23/year, –57.44 mg/L/year to 25.88 mg/L/year, –172.98 mg/L/year to 92.58 mg/L/year, –15.81 mg/L/year to 27.88 mg/L/year, and –0.05 mg/L/year to 0.61 mg/L/year, respectively. Continuous and proper groundwater-quality monitoring is critically required in all aquifer systems. The outcomes of this study will aid policy-makers in appropriately monitoring and managing groundwater quality.

Work-related musculoskeletal disorders (WMSDs) are primary cause of non-fatal injuries in construction. They involve instant or persistent stress on a worker's body (muscles, tendons, ligaments, bones) that may affect a worker's ability to perform his work or even cause chronic disability. This review helps the construction sectors in better understanding the intensity of WMSDs and the risks associated with them. This paper provides a layout for research community with a comprehensive overview of existing technique, their drawbacks, and the need for more study in order to achieve automated evaluations on construction sites. Despite the fact that assessing vulnerability to WMsSD risk factors has proven to be possible in order to reduce the rate of this injury, the area remains undeveloped due to a lack of awareness among professionals about the facilitating techniques, as well as their efficiency and limitations. This paper examines the current WMSD risk evaluation methods and outlines their convenience and disadvantages. This study helps the construction sector in better understanding the extremity of WMSDs and the risks associated with them. This review imparts the researchers with an integrated view of available methods, their drawbacks, and the need for study in order to achieve automated evaluations on construction sites.

Assessment of groundwater quality is of utmost importance to ensure sustainable use of water. Since the availability of water, irrespective of quantity and quality, varies from area to area in Thanjavur taluk. The present paper attempts to determine the spatial distribution of groundwater quality parameters and identify locations with the best quality for drinking and irrigation in the study area using GIS and WQI. Using IDW interpolation methods with ArcGIS 10.8, the spatial distribution maps of physical parameters, anions, cations, WQI, and irrigations indices have been generated. Piper pilot shows that Ca-Mg-Cl (mixed), Na-Cl, Ca-Cl, and Ca–Mg–HCO3 water types are found in the study area. Using a water quality index with a rating scale, 42.85%, 28.57%, and 14.3% of groundwater samples are fit, good, and very poor for drinking purposes, respectively. The obtained results of higher SAR, RSC, Na% show that 75% of groundwater samples are perfectly fit for irrigation purposes due to the long residence time of water, dissolution of minerals from lithological composition, and the addition of chemical fertilizers. The results of groundwater quality analysis have been used to suggest models for assessing water quality. The present study ascertained that the area's groundwater must be treated prior to consumption and protected from the perils of contamination.

The results of groundwater quality analysis have been used to suggest models for assessing water quality. The present study ascertained that the area's groundwater must be treated prior to consumption and protected from the perils of contamination.","PeriodicalId":154319,"journal":{"name":"International Journal of Civil, Environmental and Agricultural Engineering","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121452506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to determine the health consequences of fluoride contamination of groundwater in the Namakkal region in south India using the groundwater quality index (GWQI). Study area latitude and longitude: 11° 00' and 11° 30' in the north, and 77° 45' and 78° 15' in the east. Statewide, it is among the largest districts in the state. The study region occupies an area of 3406.37 km2. The geology of the studied area is mainly based on the Archaean crystalline and metamorphic complex. The district's major aquifer systems are composed of crystalline rocks that are weathered and fractured and of colluvial deposits. Alluvium and colluvium are examples of porous formations in the cross-section. Only the main river channels have alluvial deposits. The phreatic properties of groundwater Depending on the topography, these aquifers may reach 5 m saturation thickness. Groundwater samples were obtained from 58 bore well sites across the study area during the North-East Monsoon (NEM) of 2015. pH concentrations in suitable drinking water regions during the seasons assist in limiting the availability of groundwater for drinking purposes. TDS are an important factor in determining water suitability for various purposes. The groundwater sample in the study area shows cation domination in ascending order of Na+ > Ca2+ > Mg2+ > K+ due to the dissolution of aquifer minerals in rainfall in the study area. In the NEM seasons, rock dominance and anthropogenic contributions to higher Na+ > Mg2+ > Ca2+ > K+ values. Fluoride concentration differentiates into three groups such as < 0.5 indicates low risk, 0.5 to 1.5 indicates moderate risk, and > 1.5 means high risk. More than 2 fluoride implies very high risk, whereas fluoride in the range of 1.5 to 2.24 suggests a very high risk. The appraisal of non-carcinogenic risk was done to stress the health issues that succeed due to the intake and dermal contact of drinking water in the Namakkal district. The percentage of risk HQ >1 shows that 48 men groundwater samples, followed by 46 groundwater samples women and 30 groundwater samples children, constitute possible health hazards. Overall, health risk estimation results showed that all the groundwater samples have surpassed the permissible limit of HQ <1 for children.

Micro irrigation is the modern method of irrigation. By this method water is irrigated through drippers, sprinklers, foggers and by other emitters on surface and sub surface of the land. Micro irrigation can be given by tubes and drippers which deliver water directly to the base of each plant or crop. Drip irrigation, sprinkler irrigation, bubbler irrigation and sub-surface irrigation are the different types of irrigation. Soil moisture is the key variable in controlling the exchange of water and heat energy between the land surface and atmosphere. Soil moisture sensor measures the volumetric water content in the soil. Automation in micro irrigation is a system by which all the operations related to supply of irrigation water or fertilizer to the crop are carried out automatically with minimum manual interventions using soil moisture sensors.
