“…Rhizospheric soil (non-calcareous, silty clay loam, isohyperthermic Udic Hapludalfs) from a depth of 10–20 cm was acquired in early August 2018 from a rice paddy field in Gujranwala, Pakistan (32°19′N, 74°20′E). The sampling site was 226 m above sea level with a hot semi-arid climate (BSh) ( Mahmood et al, 2019 ) with an annual rainfall of around 577 mm and an average annual temperature of 23.9 °C. Field soil samples were transported to an experimental provision in zipper bags to minimize contamination.…”

The impact of environmental perturbations (e.g., nitrogen (N), phosphorus (P), potassium (K) and rice straw (Rs)) on the dynamics of soil bacterial and archaeal community are multifactor dependent and seeks more investigation concerning underlying mechanisms. Current study was designed to establish the effect of pure and mixed fertilizers on microbial community profiles in paddy soil. A short-term microcosm based experiment was established in which each microcosm is amended with N as C(H2N)2O, P and K as KH2PO4, K as KCl and Rs with concentrations equivalent to 160 kg N ha−1, 60 kg P ha−1, 130 kg K ha−1 and 1% respectively. Soil pH, electrical conductivity (EC), total C (TC), total nitrogen (TN), organic matter (OM), available K (AK) and extractable P (EP) were evaluated. To understand the microbial community variation in soil and to predict their metabolic functions, a high throughput sequencing (HTS) approach of 16S rRNA gene along with phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) was employed and analyzed. The results showed that microbial richness and diversity were increased under all amendments compared to control. Proteobacteria, Actinobacteria and Firmicutes were dominant bacterial phyla. In all amendments, regarding relative abundance, Chloroflexi, Bacteroidetes and Verrucomicrobia showed positive while Actinobacteria, Acidobacteria and Gemmatimonadetes showed negative trends when compared with controlled observations. Thaumarchaeota and Euryarchaeota were dominant archaeal phyla and exhibited increasing and decreasing trends, respectively. The PICRUSt indicated microbial community shift significantly towards amino acid, carbohydrate, energy, and lipid metabolism while less towards glycan biosynthesis, synthesis of secondary metabolites, terpenoids and biodegradation. Regarding metabolism (methane metabolism), most and least responsive treatments were predicted to be KP and controls, respectively. These findings enhanced our understanding regarding soil quality, fertilizer composition and their impact on microbial diversity.

“…The imperativeness of MSW converged the attention of researchers and substantial improvement has been observed in the last decade. Various urban regions of Pakistan such as Lahore [4][5][6], Gujranwala [7], Hyderabad [8], Faisalabad [9], and Karachi [1,10,11] has been evaluated on various bases and remarkable data has been acquired. This study contributes to filling the knowledge gap by providing experimentally calculated authenticated data of Karachi by focusing on improved collection systems, supported and organized recycling to develop state-of-the-art WMS.…”

Exploring E-Waste Resources Recovery in Household Solid Waste Recycling

The ecosystem of earth, the habitation of 7.53 billion people and more than 8.7 million species, is being imbalanced by anthropogenic activities. The ever-increasing human population and race of industrialization is an exacerbated threat to the ecosystem. At present, the global average waste generation per person is articulated as 494 kg/year, an enormous amount of household waste (HSW) that ultimately hits 3.71×1012 kg of waste in one year. The ultimate destination of HSW is a burning issue because open dumping and burning as the main waste treatment and final disposal systems create catastrophic environmental limitations. This paper strives to contribute to this issue of HSW management that matters to everyone’s business, specifically to developing nations. The HSW management system of the world’s 12th largest city and 24th most polluted city, Karachi, was studied with the aim of generating possible economic gains by recycling HSWs. In this regard, the authors surveyed dumping sites for sample collection. The sample was segregated physically to determine the content type (organic, metals, and many others). Afterward, chemical analysis on AAS (Atomic Absorption Spectrophotometry) of debris and soil from a landfill site was performed. HSW is classified and quantified into major classes of household materials. The concentrations of e-waste [Cu], industrial development indicator [Fe], and the main component of lead-acid storage batteries [Pb] are quantified as 199.5, 428.5, and 108.5 ppm, respectively. The annual generation of the aforementioned metals as waste recovery is articulated as 1.2 × 106, 2.6 × 106 and 6.5 × 105 kg, respectively. Significantly, this study concluded that a results-based metal recovery worth 6.1 million USD is discarded every year in HSW management practices.
