Pharmaceutical products are formulated to therapeutically influence the physiological systems, however, their potential health concerns which contribute in increasing environmental pollution like other most potential environmental pollutants still needs to be taken under consideration by the healthcare professionals and environmental experts. So, the contamination of treated wastewater by pharmaceutical waste and outcome of these compounds in the agricultural environment are of increasing concern and potential risk for the ecosystem. With increasing utilization of treated wastewater and biosolids in agriculture, residues of pharmaceutical and personal care products in these reused resources may contaminate the food produced via plant uptake, constituting a route for human exposure. In this article, the occurrence and behavior of pharmaceuticals waste have been briefly reviewed. Moreover, major concerns associated with exposure of biological systems of both plant and animal origin to the pharmaceutical wastes contaminating the ecosystem have also been discussed here which concluded that standard procedures and protocols should be followed to dispose of the leftovers of pharmaceuticals and/or pharmaceutical wastes.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"33 1","pages":"209-219"},"PeriodicalIF":0.0,"publicationDate":"2020-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91072203","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 study also categorizes different types of land use through supervised image classification scheme and maximum likelihood algorithm (MLA), and assess the correlation between LST and land use type of different classes. The results of the study indicate that modifications in type of land use altered spatial variations of land surface temperature in 1990 and 2015. The findings also show that the ever increasing temperature caused by impervious surfaces such as builtup area, roads, construction sites and vacant land considerably contributes to heat island effect. However, vegetation cover, green and blue spaces decrease LST and effectively relieve the effect of heat island. LST builds a strong positive correlation with NDBI and strong negative correlation with NDVI. Based on the regression analysis between LST and NDBI and NDVI, these indices can be utilized as a sign to assess the impact of LU changes on temperature. The results further indicates that LST changes follow the pattern of LU changes in Lahore and the warmness intensity has been observed highest in the high density builtup area and vacant land, while low at the green and blue spaces. The analysis reveals that an increase in LST by 1.98 °C during the period of 25 years at the rate of 0.079 °C/year in high density builtup area was due to the excessive increase in settlement growth. The study concludes that change of land use has an effect on the LST in Lahore.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"24 1","pages":"188-200"},"PeriodicalIF":0.0,"publicationDate":"2020-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73083452","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}

The results from the descriptive statistics showed that there was significant difference (P 0.05) in the mean values of Zn across the stations. The results of the relationship of the metals revealed a negative correlation between Fe and Mn with the other metals correspondingly. The results of the Kriging interpolation indicated a strong bull eye colour for stations 2 and 3 (6.42), while stations 1 and 4 were minimal (1.4). The results of the geospatial mapping indicated Fe, Zn and Mn to be the most dominant metals across the stations. The results of the PCA (principal component analysis) yielded 16 variables under 9 components with Eigenvalues >1 in components 1- 6 and these variables explained 99.99 % of the total variance in the sediment. The results of the degree of suitability and sphericity of the PCA revealed a high significant difference at P<0.001. The results of the potential ecological risk index values were very high in station 2 (824.30) and 3 (802.11) correspondingly. That of index of geo-accumulation was generally low (< 2). The findings from this study generally revealed the source apportionment of the trace and heavy metals to come from anthropogenic influences such as farming; fertilizers. Sustainable agriculture is highly recommended in order to reduce the impacts of anthropogenic activities, deterioration of the ecosystem and possible death of the life forms in this watercourse.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"28 1","pages":"176-187"},"PeriodicalIF":0.0,"publicationDate":"2020-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88334568","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}

Their discharge to nearby drains without treatment has high risk to environmental and human health. The physico-chemical strategies under practice to treat these effluents have technical and economical restrictions. Comparatively, biological treatment methods like floating treatment wetlands are less expensive and eco-friendly. Blue reactive dye enriched textile water and prepared synthetically and added to an artificial Floating Treatment Wetlands (FTWs) system vegetated with Eichhornia crassipes and Pistia stratiotes aquatic plants along with Bacillus cereus and Bacillus subtilis bacterial strains. Plant-microbe synergistic effect was studied by measuring the physico-chemical parameters i.e. pH, EC, TDS and TSS of dye enriched water after 0 (at the start of the experiment), 24, 48 and 72 h retention time. A substantial decrease in all these factors (11.34 %, 40.67 %, 64.37 %, 58.23 %, for pH, EC, TDS and TSS respectively) was noted for E. crassipes and B. cereus combination after 72 h retention time. This high lighted the fact that plant assisted microbial FTWs technique can be a unique approach to remediate the textile effluents.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"1993 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82407384","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}
