“…5). These high levels of organic materials have also been obtained by Bai et al [37] concerning urban wastewater in India and also by Gongwala et al [2] with the wastewater from another slaughterhouse in Yaounde (Cameroon). The plateau obtained between 20 and 30 min on the COD curve can be due to the fact that the organic load has become weak, which is a reminder of the impact of glidarc on dilute solutions.…”

Wastewater samples from liquid effluents of a slaughterhouse in the city of Yaounde (Cameroon) was first analyzed and exposed to gliding arc (glidarc) electric discharge to reduce the pollution load. The analyzed results showed high levels of organic pollution parameters (BOD 5 = 2000 mg/L, COD = 30544 mg/L) and the presence of a large amount of microorganisms. The UV-Visible spectrum showed an absorbance peak at 663 nm which can be attributed to chlorophyll. A hexane extract of green leaves of senna alata was thus exposed to the plasma to follow the degradation of chlorophyll. After 30 minutes of treatment, reduction rates of 96% and 73% respectively were obtained for BOD 5 and COD. The absorption peak disappears and a discoloration rate of 76% was obtained. Microorganisms such as fecal coliforms and fecal streptococci present in large quantities were completely destroyed by plasma after 15 minutes of exposure to the electric discharge. In addition, the decrease in total organic carbon showed that there was mineralization of chlorophyll contained in senna alata. This study shows that the gliding arc plasma is effective in cleaning the wastewater from slaughterhouses and in degrading chlorophyll.

“…This study focused on the third most populous region of Karnataka state and second largest city, Mysuru (12.2958° N, 76.6394° E), known as Heritage City (Pallavi et al 2021;Sharifi et al 2016). Mysuru City comprises five drainage districts which feed into three MWWTPs, all of which are facultative aerated lagoons with sedimentation basins (Bai et al 2010). More than 50% of the sewage generated in Mysuru City is received by Vidyaranyapuram MWWTP (Prashanthi and Sundaram 2016).…”

Pharmaceuticals compounds are the emerging contaminants known for their refractory and environmental persistence, which pose threat to flora and fauna. In the present study, the occurrence and possible contamination sources of four drugs, namely paracetamol, diclofenac, salbutamol and ceftriaxone in wastewater of Mysuru, India, were investigated. The said pharma compounds were analyzed in the effluent of select health care establishments and municipal wastewater treatment plant (MWWTP). The results revealed that diclofenac was omnipresent in all the samples with the peak concentration of 4.2 µg/mL, whereas salbutamol and ceftriaxone were in the range of 0.7–18.7 µg/mL and 1.25–29.15 µg/mL, respectively. In addition, paracetamol was detected only at the inlet of MWWTP with a concentration of 4.6 µg/mL. Surprisingly, the presence of relative amounts of these drugs in the treated water released from MWWTP was observed. Further, the ‘risk quotient method’ for ecological risk assessment was adopted to assess the magnitude of risk toward aquatic species. Next, the study employed the concept of citizen science to gather information on disposal and management methods of unused and expired medications at household and health care centers. This survey revealed that hospital discharges and community disposal of unused medicines contributed to incidence of pharmaceutical compounds in the local environment. Finally, a precise perspective and future challenge for the safe management of drugs are presented.

In the 21 st century the fresh water scarcity increased very rapidly due to the urbanization and industrialization process. In these conditions the urban wastewater plays an important role in the water usage criteria. In this aspect, in all the major cities, wastewater treatment plants have been constructed to treat the urban wastewater in view of decreasing the water scarcity. The presence of nutrients in the wastewater is considered as beneficial to agricultural practices. The contaminants present in the wastewater pose health risks directly to agricultural workers and indirectly to the consumers as the long term application of the wastewater may result in the accumulation of toxic elements in soil and in plants. In this way the heavy metals will circulate among the food chain and food web to cause adverse effects on human health as well as on soil health. In the present study an attempt has been made to study the characteristics of urban wastewater at wastewater treatment plant of Mysore city. And also heavy metal behavior was studied with the analysis of heavy metals in wastewater, Biosolid and receiving soil along with the plants which indicates the uptake of heavy metals.
