Wastewater (WW) volume generated from both domestic and industrial sectors has increased due to rapid industrialization and urbanization. WW is increasingly used on farms because it is cheap and easily available all year, causing various environmental and health implications. In order to evaluate Multan WW, this study characterizes 154 WW samples collected from 11 disposal stations. These samples were analysed for 23 parameters related to organic matter, nutrients, inorganic matter, and pathogens to determine pollution extent distribution, agricultural reuse potential, and WW treatment database. A major contamination concern was found regarding biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), total coliform, and E-Coli. The average values of BOD and COD were found to be 2.7 and 3.8 times higher than the permissible limits respectively. The microbiological parameters such as total coliform and E-Coli were found to be 10.6 and 36 times higher than the permissible limits, respectively. However, heavy metals and nutrients were found within the permissible limit except phosphorus. Here, the correlation study on selected WW parameters indicated the direct or indirect relationship among WW constituents and the impact of different sources of pollution on WW characteristics. The present study also presents a critical review of different treatment options according to contamination strength in disposal stations.

The current study is a retrospective epidemic report regarding dengue fever (DF) virus infection cases (2017) from fifteen districts of KPK, Pakistan. Medical records of 120948 patients were reviewed retrospectively for demographic, clinical and laboratory data. The presence of dengue infection was confirmed by NS1-ELISA and RT-PCR, respectively. The total positive cases (of suspected DF samples) were 24938 (20.6%), whereas seventy cases (0.28%) had a fatal outcome. Mean age ±SD of the dengue patients was 26±19.8 years, while; the most affected age group was from 16 to 30 years (Chi-square: 12820.125, p:0.00). The infected males were 65.3%, and that of the female was 34.7%. All the dengue-infected patients were observed with symptoms of severe fever (100%), body aches (95%), gums and nose bleeding (5%), skin rashes (30%), vomiting (70%). The highest infection rate was found in district Peshawar and that of the lowest was in Bannu, Hungu and Luki Marwat. A high rate of dengue infection was found in post-monsoon months i.e. October (41%) and September (32%) of the year. The results proved that if the dengue outbreaks reveal further in KPK, it could alarmingly increase the mortality rate. Therefore, the Department of Public Health in KPK, Pakistan may take proper measures to avoid and control dengue epidemics in the future.

The need of wastewater (WW) treatment is increasing along with the production of WW and its disposal without treatment. With a smaller footprint, ease of operation, and relatively less cost, trickling filter (TF) wastewater treatment systems have been considered to be more adoptable for domestic and industrial WW treatment in underdeveloped and/or developing countries – particularly for Asia and Africa. A relatively low-cost and operationally effective TF wastewater treatment system was developed using farm waste cotton sticks as biofilm support media. During the operation of the TF system, flow rates vary from 1.7 to 4.6 m³/hr. The attained removal efficiency for BOD (biological oxygen demand) was 69-78% and for chemical oxygen demand (COD) was 65-80%. The solids removal in TF system was 38-56% for total suspended solids (TSS) and 20-36% for total dissolved solids (TDS). Other aggregates such as turbidity and color removal were 32-54% and 25-42%, respectively. Four to five months of trouble-free operation of the developed TF system indicated the robustness and reliability of the system. Cotton sticks appeared to be a degradation-resistant alternative filter media for the TF system. Moreover, it is useful for reducing potential impacts of WW re-use at the farm level. Treated effluents through the TF system can be re-used as an irrigation water supplement in under-developed and/or developing countries.

The development of drought tolerant wheat cultivars has been slow due to lack of understanding the diagnostic physiological parameters associated with improved productivity under water stress. We evaluated responses to PEG induced osmotic stress under hydroponics in D-genome synthetic derived and bread wheat germplasm with the main aim to unravel and identify some promising attributes having role in stress tolerances. Genotypes used in this study differed in their morpho-physiological and biochemical attributes. Tolerant genotypes exhibited the ability to ameliorate harmful effects of PEG induced osmotic stress through better osmotic adjustment achieved through substantial relative water content (RWC), lowered osmotic potential, relatively stable root length having maximum water extraction capacity, significant increase in osmoprotectant concentration and relatively enhanced antioxidant activities. The results clearly revealed the importance of synthetic derivatives over check cultivars and conventional wheats in terms of osmotic stress responses. Interestingly, synthetic-derived advanced lines with Aegilops tauschii in its parentage including AWL-02, AWL-04 and AWL-07 proved superior over the best rainfed check cultivar (Wa-01). It was concluded that syntheticderived wheats has great potential to improve a range of stress adaptive traits. It could, therefore, be recommended to be a useful strategy for allowing modern bread wheat to become adapted to a wider range of environments in future climate change scenarios.
