The discussed below. 3.1 Catalyst Some metal, metal

The PMNC prepared from inorganic materials using in situ polymerization and composite formation are suitable as catalysts, sensors, reducing agents and to microbe killing agents.23 Scientists have synthesized zinc oxide polyaniline nanocomposite which has improved interface. Due to its synergistic effects it exhibited thousand times better electrical conductivity.24 Addition of nanoparticles in polymer matrix improves the polymer properties and produce PNCs with desired properties. Catalytic, adsorption, and mechanical properties of PNCs are generally used for the purification of water. These properties of PNCs are briefly discussed below. 3.1 Catalyst Some metal, metal oxide, and sulfides are used as catalysts for […]

EFFECT OF PRETREATMENT OF CRUDE OIL CONTAMINATED DIET WITH OIL PALM LEAF ON LIPID PEROXIDATION AND XANTHINE OXIDASE ACTIVITY IN THE KIDNEY OF RAT Achuba ,F. I . Department of Biochemistry, Delta State University, PMB 1, Abraka Nigeria. [email protected]   Abstract The toxicity of petroleum hydrocarbon across the living systems is now a common knowledge among the scientific community. What is lacking is a mini-scale antidote that can be adopted by the inhabitants of crude oil producing areas of the world. This was the reason for this study. The study was comprised forty eight female Wister rats divided into six […]

Turtles ocean. The sea turtles that occur on

Turtles are one of the oldest reptile groups. They are classified as amniotes. They have existed for a long time ago, specifically, sea turtles which have existed for more than 60 million years ago (Dobbs 1). Turtles, in general, have survived the journey of time and is threatened by the pollution that humans have created in the ocean. The sea turtles that occur on the coasts of America are absolutely endangered. Sea turtles are significantly important for the ecosystem. Without sea turtles, ecological disturbance will eventually occur in the oceans. Human threatens sea turtles by their impulsive actions. Therefore, humans […]

The a flock of rabbits nearby. (Jais).The Ecosystem

The Spanish Imperial Eagle is a raptor that is greatly endangered, it lives mostly in Spain and some parts of Portugal and Morocco. Spain:According to “Spain Population (LIVE).”Spain has a population 46.4 million people. According to weatheronline.co.uk. Spain’s climate in the summer is dry and hot. In the winter Spain is very rainy and wet. Spain also has many beautiful beaches, forests, rivers and mountains and is located in south west Europe. (“Spain Population (LIVE)”) (“weatheronline.co.uk.”). Its Habitat:According to Jais, the Spanish Imperial Eagle lives in forests and marshes. Sometimes they can also be found in agricultural areas. If you […]

Recycling

Recycling Name: Course: Date: Recycling 1) An ecosystem can be described as a complex community of living organisms together with the non-living constituents, interrelating with each other within the environment they inhabit as a system. The interactions between the living and non-living components are defined by the unique process of nutrient sequences and flow of energy which are the source of interaction between the constituents. Ecosystems vary in size but commonly accommodate particular limited spaces. However, the interactions between the components are being disrupted by destructive processes. An example of a complex ecosystem that is under threat due to human […]

biomes

Biomes Name: Tutor: Course: Date: Name: Tutor: Course: Date: Biomes Biomes comprise comparable climatic regions scattered around the earth. These regions constitute communities of animals as well as vegetation and soil life forms. Typically, biomes gain description as major ecosystems. Various factors define biomes in scientific context. Such factors typically comprise aspects such as plant configurations, leaf categories, plant spacing and climate. Additionally, specific patterns of ecological sequence and pinnacle vegetation assist in identifying biomes. Thus, such identification categorizes biomes into two distinct groups. These groups comprise Terrestrial biomes and Aquatic biomes. However, the modern environment complicates the longevity of […]

Assignment 1

Assignment 1 Name: Course: Lecturer: Institution: Date: Assignment 1 Introduction Environmental pollution is the number one contributor to global warming. Often, some geologists and other scholars argue that pollution is not among the contributors of global warming. Hence, they tend to decide that human activity is not the cause of global warming. However, it should be noted that human activities may affect the environment positively or negatively, it only depends on how the activity is viewed. Therefore, in the paper, an article in the New York Times involving a human activity that affects the environment both positively and negatively, is […]

Anthropocene

Name: Lecturer: Course: Date: Anthropocene Anthropocene is a term that refers to influence that human beings’ activities have on the environment. It refers to the evidence that can be seen from on the environment because of man’s activities. Recently there has been a new geological period because of all the activities that man is involved with today. This is because there are many new activities that man is engaging in. These activities also have an impact on the environment in the same way. The more they are, the more the environment changes. It is because of this that scientists are […]

Concentration within the prescribed limits. Target hazard quotients

Concentration of heavy metals (Cr, Cu, Zn, As, Pb and Cd) were determined to evaluate the potential human health risks in nine different indigenous fish species in Noakhali region. Among the metals apex value was found 1.53 mg/Kg and the nadir value was found 0.51 mg/kg.  The results revealed that all the heavy metals were less than the permissible levels stated by the European Union, Food and Agriculture Organization, World Health Organization guidelines, Western Australian Food and Drug regulations, UK, Spanish, and Turkish legislations. Moderate positive correlations was found between Cu and Pb (r =0.57); and As and Cd (r […]
