1. Water sampling is the process of taking water samples for analysis to check water quality.
2. There are two main types of water sampling: grab sampling, which collects discrete samples at a point in time, and composite sampling, which mixes multiple grab samples.
3. The water sampling procedure involves identifying sampling points, collecting samples using proper containers and labels, and transporting samples to a laboratory for testing of various physical, chemical, and bacteriological parameters.

Analysis of Water Quality Using Physico-chemical Parameters of Mula-Mutha Riv...ijtsrd
We wants to present an extensive work on physico-chemical parameters of water samples of Mula-Mutha river at Pune (Maharashtra). Water samples under investigations were collected from Khadkwasla dam to Sangam Bridge during pre monsoon (April “ May2016) monsoon (July “ August2016) and post monsoon (October “ November2016) seasons. The observed values of different physico-chemical parameters like pH, DO, BOD, COD, Chloride, Nitrate, Sulphate, Calcium, Magnesium and Hardness, etc. of samples were compared with standard values recommended by world health organization (WHO). The Mula-Mutha River water in Pune had deteriorated in quality. Its biological oxygen demand, an indicator of organic pollution, has risen to over 30 mg/l, more than ten times the permissible limits for bathing. Municipal Corporation is currently supplying water sufficient for the projected population. More water means more sewage, beyond the quantum its sewage treatment plants can treat. As a result there is greater pollution loads discharged in to the Mula-Mutha, two rivers that confluence within city limits and serve to flush away Punes excreta. All the physico - chemical parameters for pre monsoon, monsoon and post monsoon seasons are within the highest desirable or maximum permissible limit set by WHO except some of the parameters like DO, BOD,COD, chloride, calcium, magnesium and hardness.

Simultaneous Quantitation of Manganese (II) and Iron (III) In An Industrial E...IOSRJAC
In the present study, a successful attempt has been made to develop a simple method for the simultaneous determination of manganese (II) and iron (III) in an industrial effluent using differential pulse polarography (DPP) technique. Quantification of manganese (II) and iron (III) was done in Triethanolamine and KOH as a supporting electrolyte. The polarogram recorded for the industrial effluent in triethanolamine and KOH showed two peaks at -0.3V and -0.82V vs. saturated calomel electrode which were confirmed to be of manganese (II) and iron (III) respectively by the method of standard addition. The linear working range for manganese (II) and iron (III) both was 1.408 µg/mL to 4.977 µg/mL. The proposed method was found to be simple, precise, and accurate and can be successfully applied for the analysis and simultaneous determination of manganese (II) and iron (III) in industrial effluents.
Abstract— The water quality was studied for selected samples from groundwater and network water-supply. The values of NH3, NO3-, pH, TDS, alkalinity, hardness, Pb, Cd, Fe3+ and Mn2+ were estimated. Ammonia values ranged between 0.07-0.7 ppm. Nitrate values ranged between 2.4 and 0.35 ppm. The TDS was between 645 ppm and 480 ppm. For Fe3+ and Mn2+ the values are below the limits of WHO except for well 9; and manganese in wells 6-10. Several wells showed values of Cd above the Saudi STD. The network water-supply in Tabuk city was investigated. The TDS values for these samples were between 500-600 ppm. The hardness values exceed the Saudi STD limit. When ammonia was tested, only one sample showed high value. Chloride level was below 158 ppm, but sulfate values for most samples were 128-222 ppm. For iron only one sample (well no. 9) was above the permissible limit.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

2. WHAT IS SAMPLING ?
In research terms a sample is a group of people, objects, or items that are
taken from a larger population for measurement. The sample should be
representative of the population to ensure that we can generalize the
findings from the research sample to the population as a whole.
3. WATER SAMPLING
Water sampling is the process of taking a portion of water for
analysis or other testing, e.g. drinking water to check that it
complies with relevant water quality standards, or river water to
check for pollutants, or bathing water to check that it is safe for
bathing, or intrusive water in a building to identify its source.
