The Impact of Deposit Materials on Environment Pollution Around Industrial Areas in Kosovo | Chapter 5 | Research Advances in Environment, Geography and Earth Science Vol. 10

Human evolution, together with the industrial revolution, has caused great changes in the quality of the natural environments, in which man lives and exercises his activity. The soil plays an important role in this process, as it serves as a “repository” for the accumulation of chemical pollutants. Heavy metals, unlike organic pollutants, are not biodegradable. The presence of these pollutants in the environment is related to industrial activities, emissions during the burning of fossil materials, family economy and traffic. Also, persistent organic pollutants (POPs) remain at the center of scientific attention, due to their low degradation rate, lipophilic nature, toxicity, ability to be transported over long distances, and to bioaccumulate in living organisms. Around 70 years ago, various manufacturing industries were established in Kosovo, primarily focusing on ferrous metallurgy and coal extraction for electricity production. Many of these manufacturing industries are still operational today, though some no longer function at their full production capacity as they did two decades ago.

Pollution Evaluation and Risk Assessment of Polycyclic Aromatic Hydrocarbons (PAHs) in Water and Coastal Sediment from two Rivers in Douala-Cameroon | Chapter 10 | Current Advances in Geography, Environment and Earth Sciences Vol. 3

 The purpose of this study was to determine the amount of environmental danger posed by two rivers by examining the distribution of PAHs in their water bodies and sediment. The Mboppi River and the Ngoua River, both in Douala, Cameroon, were researched. The first is in a commercial zone, while the second is in an industrial zone. During the dry and wet seasons, water and sediment samples were taken. During the wet season, total PAH concentrations in sediment from the Ngoua River ranged from 140.42 g.g-1 to 229.47 g.g-1 dry matter in sediment, while during the dry season, total PAH concentrations in sediment ranged from 48.89 g.g-1 to 333.49 g.g-1 dry matter in sediment. The overall quantity of PAHs in the Ngoua River was found to range between 29.13 to 461.94 g.L-1 in extracts from water samples. Due to industrial operations, high molecular weight (HMW) PAHs predominated in all samples. PCA revealed significant changes in the characteristics of samples obtained upstream and downstream of Nettoycam Company along the Ngoua River or Mboppi Market along the Mboppi River, as well as samples collected during rainy and dry seasons. PAHs with two or three rings have low amounts and are even undetectable in some sediment samples, yet they are detected in both rivers' water samples. All of the examined media (water and sediment) from the rivers are hazardous to the environment. The Toxicity Equivalent (TEQ) concentration was used to determine the toxicity of the substance.

Determination of Some Biochemical Indices in Catfish from Rivers, Swamp and Commercial Fish Ponds in Oil and Non-oil Polluted Areas in Rivers and Anambra States, Nigeria: A Comparative Assessment | Chapter 9 | New Innovations in Chemistry and Biochemistry Vol. 4

 The ability of activated carbon (CSAC) and polypyrrole coated sawdust (PPy/SD) obtained from the fruit of Cordia sebestena's gardening plant material to adsorb acid orange -7 from aqueous solutions was examined. The adsorption method is a viable treatment option, particularly if the adsorbent is affordable and easily available. Variations in experimental parameters such as pH, initial dye concentration, contact time, and temperature were used to conduct batch mode adsorption investigations. The kinetic data for both adsorbents was analysed using pseudo first order and pseudo second order models at various concentrations and temperatures. Freundlich and Langmuir models were used to analyse the equilibrium data. Thermodynamic research were also taken into consideration. Finally, CSAC's performance was compared to that of PPy/SD. The experimental results showed that PPy/SD is more effective than CSAC at removing Acid Orange 7 from aqueous solutions.

Study on Source and Distribution of Polycyclic Aromatic Hydrocarbons (PAHs) in Water and Coastal Sediment from the Ngoua River in Douala, Cameroon | Chapter 10 | Modern Advances in Geography, Environment and Earth Sciences Vol. 6

 The goal of this monitoring project is to identify the source and distribution of Polycyclic Aromatic Hydrocarbons in Ngoua River water and coastal sediments. The identification and quantification of 15EPA-PAHs in water and sediment samples collected from the Ngoua River in Douala, Cameroon are reported in this research. The PAH pollution in the Ngoua River had to be assessed by identification and quantification. During the dry and wet seasons, water and sediment samples were taken. Eight (8) samples were collected, with four samples each season and substrate. The PAHs fraction was extracted from water using magnetic agitation and hexane as a solvent. Using a chromatographic column, PAHs were separated, identified, and quantified using Gas Chromatography (GC/FID). During the wet season, the total concentration in sediment ranged from 140.42 g/g to 229.47 g/g dry materials, and during the dry season, it ranged from 48.89 g/g to 333.49 g/g dry matters. Due to industrial operations, high Molecular Weight (HMW) PAHs predominated in all samples. The quantities of PAHs discovered upstream were consistently lower than those found downstream, indicating a role for Nettoycam Company in local PAH contamination. The results of principal component analysis (PCA) revealed significant differences in the features of samples taken upstream and downstream of Nettoycam Company, as well as samples collected during rainy and dry seasons. The overall content of PAHs in river samples ranges between 29.13 to 461.94 g/L, according to examinations of extracts from water samples. PAHs with two or three rings have low quantities and are even undetectable in some tests. PAHs with more than four rings had the highest quantities in the river, regardless of seasonal change. Some ratios revealed a prevalence of petroleum sources of hydrocarbons.
