Removal of Heavy Metals from Groundwater by Hydrous Ferric Oxide-Modified Peanut Shell

This study reports the adsorption capacity of copper Cu (II) and nickel Ni (II) of biochar obtained from peanut shell. The kinetics and equilibrium of biosorption were examined in detail. Two kinetic models (pseudo-first order and pseudo-second order) were used to correlate the experimental data and to determine the kinetic parameters. Two well-known adsorption isotherms were chosen to describe the biosorption equilibrium (Langmuir and Freundlich). The equilibrium isotherms showed that modified peanut shells possess high affinity, sorption capacity for Cu (II) and Ni (II) ions, sorption capacities of 37.443 mg/g Cu (II) and 28.626 mg/g Ni (II) biomass, respectively. All results showed that peanut shells biomass is an attractive, alternative low-cost bio sorbent for removal of heavy metal ions from aqueous media, therefore biomass materials find good application prospects.

Arduino Use in Education Systems to Monitor the Noise in Schools Classrooms in Qatar

Many students suffer from the sound of air conditioners and others suffer from light intensity in classroom. The air conditioners and light intensity affect the efficiency and quality of education. Urduino is used a lot in industrial areas because there is a lot of noise pollution. Additionally, it can be used in high traffic regions as well as to monitor noise in different parts of the city. It can also be used in education systems to monitor the noise in classrooms. The purpose of this study was to monitor the noise in classrooms by Arduino Nano that interfaced with a Sound Sensor. A study was conducted to determine the ambient sound and light intensity of a convenience sample at school during September, October and November 2021. Six classrooms’ samples corresponding to hourly fractions of the average sample broken down into the following periods: from 10:00 am to 2:50 pm. Sound levels were measured to assess acoustic conditions. Light levels were measured to assess light conditions. Each classroom from 1 to 6 was tested the ambient sound intensity and light using an Arduino. Noise varies with time and place. The sound level varies between 27.5 dB and 65 dB with the average sound level in the classrooms was 43.53 dB greater than recommended sound level limit of 35 dB. The light intensity varies between 62.50 lux and 208.5 lux. The average light levels around the recommended 300 lux. Everyone emphasized the quality of using the device to measure the noise level in the classroom. The use of the device leads to monitor the noise of the air conditioner or replacing it. The device has the potential to significantly change the noise pollution monitoring system at school. Researchers recommend all students and authorities the importance of the Arduino.

Pollutant Emissions of Vehicle Tyres and Pavement in Real Driving Conditions

Non-exhaust road transport emissions, particularly tyre-pavement abrasion, contribute to poor air quality. This original work is on particle emissions caused by tyre-pavement abrasion in real driving conditions in urban, suburban and motorway areas. The collected data were analyzed according to the size, the number and chemical identification. Multivariate analysis provided clusters of size and chemical elements. Results showed the predominant particles (diameter φ < 1 μm and φ ε]1-2 μm]) for urban and suburban experiments, and ]1- 3 μm] on motorways. A confirmed shift phenomenon at the close-to-the-source showed particles of large sizes [5- 10 μm]. The obtained clusters were: 1. Aluminosilicate, iron compounds, silicate free of aluminum (70%). 2. Ferrosilicon, silica, compounds of calcium, manganese, iron oxide, compounds of aluminum, sulfur, copper and zinc (29%). 3. A mix of various traces (1%). This paper will contribute to the development of new green technologies dedicated to improving sustainable road transport.

Assessment of Particulate Matter, Volatile Organic Compounds, and Suspended Solids in Some Settlements around Port Harcourt Metropolis, Rivers State Nigeria

There is a proliferation of particulate matter in the atmosphere within and around the cities because of increased industrial activities. It is thus hypothesized that increase in human activities lead to increase in pollutants concentration inside (n=80 houses sampled) and outside residential areas. Thus, to investigate the air quality at different residential areas within indoor and outdoor environment air samples were collected using Particle Counter (Model: HHPC MET), and Gas Monitor (Aeroqual series 500) to determine particulate matters (i.e., PM10, and PM2,5), volatile organic carbon (VOC) and total solid particle (TSP).

Conventional and Advanced Nanotechnological Approaches for Wastewater Treatment

The industrialization, urbanization and economic growth have placed a much higher demand of clean water and energy worldwide. The human activities have constantly been contaminating the reservoirs of fresh water which as a result, has triggered a global challenge to keep up the demand and supply of the fresh water for an optimal human survival. Wastewater effluents generated through commercial and industrial activities have been released to the freshwater resources either directly or indirectly

Upswing in Industrial Activity and Infant Mortality During Late 19th Century US

This paper aims to assess the effects of industrial pollution on infant mortality between the years 1850-1940 using full count decennial censuses. In this period, US economy experienced a tremendous rise in industrial activity with significant variation among different counties in absorbing manufacturing industries, which is used as a proxy for variation in space-time industrial pollution.

A Review of the Economist’s Approach to Pollution and Its Control

Pollution, being a social and environmental problem, has been a subject of inquiry by environmental economists. Environmental economists see pollution as an externality problem or a market failure, and have therefore investigated factors affecting pollution and its control.

Air Pollution Report of Agartala city Tripura, India

Air pollution is a major and growing risk factor for ill health in India, contributing significantly to the country’s burden of disease. As per the Global Burden of Disease comparative risk assessment for 2015, air pollution exposure contributes to approximately 1.8 million premature deaths and 49 million disability adjusted life-years (DALYs) lost, ranking it among the top risk factors for ill health in India. Home to 10 of the top 20 cities with the highest annual average levels of PM2.5 as per the WHO Urban Ambient Air Quality Database (2016), and with several studies showing a worsening trend over the time, it is safe to say that rapid urbanization and industrial development have adversely affected urban air quality due to vehicular and industrial emissions. Simultaneously, over two-thirds of rural Indians caught in the ‘chulha trap’ use biomass fuels such as wood, dung or coal to satisfy their cooking and heating needs, resulting in smoke-filled homes and extremely high levels of exposure especially to women and children [1]. With respect to other cities of India, our smallest state Tripura (Agartala city) also have the high value of PM10 & PM2.5.The value of particulate matter is above the CPCB standards and also WHO standards. On the Basis of the study report we made some suggestion to overcome these conditions.

Heavy Element Accumulation in Aquatic Beetles of the Genus Enochrus (Coleoptera: Hydrophilidae) in Erzurum Province

In the present study, fourteen heavy elements (Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Sr, Pb) accumulation in sediment, water and Enochrus spp. species organs (total body) were evaluated. For this purpose, water, sediment and Enochrus spp. were collected from nine wetland sites in Erzurum province (Turkey).
